Methodology

Methodology Surface Machining is a versatile application, fully adapted to your needs and your working methods whether they are machining area-oriented or operation-oriented. You can either define the machining areas on your part and then assign an operation to each of them or you can define your machining process as a series of operations with an area to machine for each operation. A machining area can be: the whole part (for example, in roughing), a subset of the faces on the part, a subset of faces on the part with a limiting contour. The Getting Started chapter contains two sections, one which demonstrates operation-oriented machining and another which demonstrates area-oriented machining. Before starting work with Surface Machining, please ensure that you have an open file (CATPart or CATProduct) and that you are in the Surface Machining workbench (Start > NC Manufacturing > Surface Machining). Here is a suggested order for operations in a machining program: rough machining operations, (semi-)finishing operations, detection of unmachined areas, reworking of unmachined areas, generation and output of documentation.

Area-oriented

Area-oriented methodology is useful when you have a complex part to machine and you know in advance what kind of operation you are going to apply to each separate area. This approach is of great use when, for example, you are going to machine a "family" of similar parts and when you have dedicated machines for mass production. You define the areas on one part, you assign an operation to each area, and then you machine. At the end you have a program that you can apply to all of the "members" of the "family" at least working cost because: the machining strategy has already been defined (chosen operations), the tool has already been defined, only the area need be redefined,

Methodology

1.

you know exactly what kind of output you require, and as a result the computation can be run in batch to further reduce time loss. Define all of the separate areas to machine on your work piece.

2.

Select the area or areas you want to machine with a particular operation.

3.

Click on the appropriate icon (for example, sweeping).

4.

Change the parameters in that operation (if required). The only mandatory data for a operation is the area to machine (with the exception of roughing which requires a rough stock too) and all of the other parameters have default values.

5.

Operation-oriented

We recommend that you use the default parameters first unless you are sure of the values you wish to enter. Compute the operation. If the results are satisfactory, repeat steps 2, 3, and 4 for all of the other areas to machine. Use operation-oriented machining when you want to progressively define your machining program operation-by-operation sequentially. Each operation has the area it deals with defined as part of its data.

1.

This approach is useful for single or limited part production because it allows you to define your requirements step-by-step. Choose the operation you want to use.

2.

Click the "part" area in the geometric components of the operation.

3.

Select the area(s) to machine either as the whole part with the contextual menu or as a face or group of faces with the face selection wizard. Change the other parameters in the operation (if required).

4.

The only mandatory data for a operation is the area to machine (with the exception of roughing which requires a rough stock too) and all of the other parameters have default values.

5.

We recommend that you use the default parameters first unless you are sure of the values you wish to enter. Compute the operation. If the results are satisfactory, continue defining the remaining operations for your machining program

What's new

What's new? General functions New: There is a new cycle, spiral milling, that has been developed to finish-mill flat surfaces. New: There are three new types of approach and retract for sweeping, contour-driven and pencil operations. New: There is now an option that allows you to extend paths in a straight line to link two areas in a part when they are separated by a hole or a gap. You can find this option in the sweeping and contour-driven operations. Enhanced: The stepover options have been enriched with the possibility of defining the stepover by two points.

Part to machine New: You can now apply an overall default offset to an offset group. Enhanced: The Face selection wizard now has an option that lets you select faces that are normal to an axis or parallel/perpendicular to a selected face. New: You can now use faces from existing machining areas or offset areas to form a new machining area.

Tools to use New: tapered tool/conical mill for sweeping, contour driven and pencil operations and also for rework areas.

Roughing New: You can now choose whether or not you want to contour the rough stock before milling. This option is intended for use with zig-zag tool path style only.

ZLevel New: You can now use variable offsets in ZLevel operations.

http://dsfr2e/itprm/doc/CXR7doc/doc/online/smgug/smgugwn.htm (1 of 2) [5/17/2001 3:06:30 PM]

What's new

Tool Path Editor New: You can now create multiple transformations of a tool path. All of the tool paths now appear in the specifications tree under the operation they belong to. Enhanced: If a tool path is not closed (for example, if you have cut an area out of it), you will be informed of this by the word open after its name in the specifications tree. Enhanced: When you reverse a tool path, a message now tells you that it has been reversed. New: You can now add approaches or retracts to a tool path via an item in the tool path contextual menu.

Getting Started

Getting Started Before getting to grips with all of the Surface Machining capacities, here are two short step-by step tutorials that will help guide you through the key functionalities. You will learn how to use the functions listed below and learn how to define areas on the part to machine, use specific machining operations on the part and output data. There are two ways of defining your machining program, you can either base it on operation definition or on area definition. Try both tutorials to see which method suits your working techniques best. The tutorials should take you 30 minutes each to complete. Operation-oriented machining Area-oriented machining

Roughing operations

Rough Machining Operations These are the tasks that you will use for rough machining the part. Create a sweep roughing operation: Select the sweep roughing icon, choose a part to machine and specify the tool to be used. You can also specify machining parameters, feedrates and spindle speeds. Create a roughing operation: Select the roughing icon, choose a part to machine and specify the tool to be used. You can also specify machining parameters, feedrates and spindle speeds.


Sweep roughing

Sweep Roughing This task shows you how to insert a sweep roughing operation into the program. Sweep roughing is an operation which allows you to rough machine parts by vertical planes. To create the operation you define: the geometry of the part to machine

,

the parameters of the machining strategy the tool to use

;only end mill tools

the feedrates and spindle speeds the macros

, are available for this operation,

,

.

Only the geometry is obligatory, all of the other requirements have a default value. Either: make the Manufacturing Program current in the specification tree if you want to define an operation and the part/area to machine at the same time, or select a machining feature from the list if you have already defined the area to machine and now you want to define the operation to apply to it. Below we are going to see how to do the first of these. Open file Basic1.CATPart then select NC Manufacturing > Surface Machining in the Start menu. 1.

Select the sweep roughing icon

.

A SweepRoughing entity and a default tool are added to the program. The dialog box opens at the geometry tab page

.

This page includes a sensitive icon to help you specify the geometry to be machined. The area that represents the part geometry is colored red indicating that the geometry is required for defining the area to machine. All of the other geometry parameters are optional.

Sweep roughing


Sweep roughing - geometric components

Sweep Roughing - Geometric Components In the geometric component tab you can define the area to machine either: by clicking on the face definition area and using the face selection wizard, by passing the mouse over the face definition area and choosing Body in the contextual menu if you wish to machine a whole part and not just an area on it, or by choosing a pre-defined area like this:

The other geometric components that you can select in the view (but that are not obligatory) are: the check element. The check is often a clamp that holds the part and therefore is not an area to be machined.

an area to avoid if you do not wish to machine it. the safety plane. The safety plane is the plane that the tool will rise to at the end of the tool path in order to avoid collisions with the part. You can also define a new safety plane with the Offset option in the safety plane contextual menu. The new plane will be offset from the original by the distance that you enter in the dialog box. an upper plane which defines the highest plane that will be machined on the part, a lower plane which defines the lowest plane that will be machined on the part, the limit line which defines the outer machining limit on the part. the offset on the part. the offset on the check element.



You can also define the following parameters: Stop position defines where the tool stops: outside stops the tool outside the limit line, inside stops inside the limit line, on stops the tool on the limit line. Stop mode defines which part of the tool is considered at the Stop Position, i.e. whether it is the contact point or the tool tip. Offset is the distance that the tool will be either inside or outside the limit line depending on the Stop Mode that you chose. Part autolimit. If you activate Part autolimit, the tool will not go beyond the edge of the part. Part autolimit and the limiting contour can be used individually or together to define the area you want to machine. In the pictures, the blue outline is the part edge, the yellow part is the area that will be machined, the black line is the limiting contour: If you use Part autolimit, the whole part is machined.



If you use Limiting contour, only the area inside the limiting contour is machined.

You can now either run the operation on the part, store the operation that you have just defined or define other parameters in the machining strategy, tool data, speeds and rates, or macro data tabs first.


Sweep roughing-machining strategy

Sweep Roughing - Machining Strategy In the machining strategy tab, you can define the cycle type, the tool path style, the machining tolerance, the stepover distance and the maximum cut depth. You can also choose the tool stepover direction and the tool axis. The sensitive icon illustrates the roughing type you select: ZOffset; the tool path is offset from the part. ZPlane; the part is machined plane by plane. ZProgressive; the part is machined by interpolating the tool path between the part and the top of a theoretical rough stock. You can change the tool axis and the machining direction in the sensitive icon. Change the tool axis and the machining direction with Select in the contextual menu which will display a dialog box where you can choose between selection by angle and selection by coordinates. Selection by angle lets you choose the tool axis by rotation around a main axis. Angle 1 and Angle 2 are used to define the location of the tool axis around the main axis that you select. There is also a button that lets you reverse the direction of the axis with respect to the coordinate system origin.

Selection by coordinates has the following options: Feature-defined; you select a 3D element such as a plane that will serve to automatically define the best tool axis.



Selection; you select a 2D element such as a line or a straight edge that will serve to define the tool axis or machining direction, Manual; you enter the XYZ coordinates, Points in the view; click on two points anywhere in the view to define the tool axis or machining direction.

The machining tab concerns the tool path style, stepover side and machining tolerance. Consider the tolerance value to be the acceptable chord error. The tool path style can be: Zig-zag; the tool path alternates directions during successive passes,



One-way next; the tool path always follows the same direction during successive passes and goes diagonally from the end of one tool path to the beginning of the next. One-way same; the tool path always has the same direction during successive passes and returns to the first point in each pass before moving on to the first point in the next pass. The stepover side can be either to the left or the right of the tool path and is defined with respect to the machining direction. The strategy tab allows you to define the distance which is the width of the overlap between two successive passes and the maximum depth of cut.

Only the geometry is obligatory, all of the other requirements have a default value. Either: make the Manufacturing Program current in the specification tree if you want to define an operation and the part/area to machine at the same time, or select a machining feature from the list if you have already defined the area to machine and now you want to define the operation to apply to it. Below we are going to see how to do the first of these. Open file SurfaceMachining3.CATProduct, then select NC Manufacturing > Surface Machining in the Start menu. Then display the model in wireframe mode with this icon 1.

Roughing - geometric components

Roughing - Geometric Components In the geometric component tab. You can define the area to machine either: by clicking on the face definition area and using the face selection wizard, by passing the mouse over the face definition area and choosing Body in the contextual menu if you wish to machine a whole part and not just an area on it, or by choosing a pre-defined area like this:

The other geometric components that you can select in the view (but that are not obligatory) are: the rough stock. If you do not have a rough stock you can create one automatically. the check element. The check is often a clamp that holds the part and therefore is not an area to be machined. an area to avoid if you do not wish to machine it (the small light brown corner near the part selection area). the safety plane. The safety plane is the plane that the tool will rise to at the end of the tool path in order to avoid collisions with the part. You can also define a new safety plane with the Offset option in the safety plane contextual menu. The new plane will be offset from the original by the distance that you enter in the dialog box. an upper plane which defines the highest plane that will be machined on the part, a lower plane which defines the lowest plane that will be machined on the part, an imposed plane that the tool must obligatorily pass through. Use this option if the part that you are going to machine has a particular shape (a groove or a step) that you want to be sure will be cut, a start point where the tool will start cutting. Use this option when accessing the part from the outside. the offset on the part. the offset on the check element.


Roughing - geometric components

You can also define the following parameters: Position defines where the tool center stops: outside stops the tool outside the rough stock, inside stops the tool inside the rough stock, on stops the tool on the rough stock. Offset defines the distance that the tool can overshoot the Position. It is expressed as a percentage of the tool diameter. This parameter is useful in cases where there is an island near the edge of the part and the tool diameter is too wide to allow the area behind the island to be machined. This parameter can only be used of the position is inside or outside and you must check the Overshoot box. There is an option which allows you to replay all previous operations. You can now either run the operation on the part, store the operation that you have just defined or define other parameters in the machining strategy, tool data, speeds and rates, or macro data tabs first.


Roughing-machining strategy

Roughing - Machining Strategy Here you can define parameters concerning the style of machining, the machining strategy, and the zone to machine. You can also choose the tool axis. The sensitive icon illustrates the tool path style that you chose. Change the tool axis with Select in the contextual menu which will display a dialog box where you can choose between selection by angle and selection by coordinates. Selection by angle lets you choose the tool axis by rotation around a main axis. Angle 1 and Angle 2 are used to define the location of the tool axis around the main axis that you select. There is also a button that lets you reverse the direction of the axis with respect to the coordinate system origin.

Selection by coordinates has the following options: Feature-defined; you select a 3D element such as a plane that will serve to automatically define the best tool axis. Selection; you select a 2D element such as a line or a straight edge that will serve to define the tool axis, Manual; you enter the XYZ coordinates, Points in the view; click on two points anywhere in the view to define the tool axis,



The Machining tab defines: the Tool path style which can be: One-way next; the tool path always has the same direction during successive passes and goes diagonally from the end of one tool path to the beginning of the next. One-way same; the tool path always has the same direction during successive passes and returns to the first point in each pass before moving on to the first point in the next pass. Zig-zag; the tool path alternates directions during successive passes. Helical; the tool moves in successive concentric passes from the boundary of the area to machine towards the interior. The tool moves from one pass to the next by stepping over. Contour only; only machines around the external contour of the part.



Concentric; the tool removes the most constant amount of material possible at each concentric pass. The tool is never directly in the heart of material. It also respects the given cutting mode in all cases. The approach mode with this style is always Helix. the Machining tolerance value, consider it to be the acceptable chord error, the Machining mode which defines the type of area to be machined and can be: By plane; the whole part is machined plane by plane, Pockets only; only pockets on the part are machined, Outer part; only the outside of the part is machined, Outer part and pockets; the whole part is machined outer area by outer area and then pocket by pocket. the Cutting mode which can be Climb or Conventional.

The Strategy tab defines: the maximum depth of cut which is the depth of the cut effected by the tool at each pass the overlap between two successive passes. Define this distance by choosing either: By ratio and enter a percentage of the tool diameter, By length and enter a length.

The Zone tab includes: Min. area which lets you filter out areas that you consider to be too small (in millimeters) to be machined. Tool core diameter is the diameter of the tool top that does not actually cut the material. Part contouring is an option that is only used with the zig-zag tool path style. With part contouring switched on, the tool goes round the outside contour of the part before continuing to zig-zag. Deactivating this option allows you to gain machining time. The tool that you are using and the part you are working on must be such that contouring the rough stock is superfluous.



With part contouring switched on. Note how the tool went round the area to machine first:

With part contouring switched off and exactly the same parameters. Note that the tool goes straight into zig-zag mode:


Roughing - Macro data

Roughing - Macro Data The Macro tab defines the tool engagement parameters. There is a button that optimizes tool retract movements. This means that when the tool moves over a surface where there are no obstructions, it will not rise as high as the safety plane because there is no danger of tool-part collisions. The result is a gain in time. In some cases (where areas of the part are higher than the zone you are machining and when you are using a safety plane), the tool will cut into the part. When this happens, deactivate the Optimize retracts button.

The Axial safety distance is the maximum distance that the tool will rise to when moving from the end of one pass to the beginning of the next. The approach mode can be: Plunge; the tool plunges vertically, Drilling; the tool plunges into previously drilled holes. You can change the drilling tool diameter, angle and length, Ramping; the tool moves progressively down at the Ramping angle, Helix; the tool moves progressively down at the ramping angle with its center along a (vertical) circular helix of Helix diameter. Approach distance is the engagement distance for plunge mode. The Radial safety distance is the tool clearance distance with respect to the sides of the part.

Sweeping


Sweeping - geometric components

Sweeping - Geometric Components In the geometric component tab you can define the area to machine either: by clicking on the face definition area and using the face selection wizard, by passing the mouse over the face definition area and choosing Body in the contextual menu if you wish to machine a whole part and not just an area on it, or by choosing a pre-defined area like this:

You can also use an Offset Group on the part. The other geometric components that you can select in the view (but that are not obligatory) are: the check element. The check is often a clamp that holds the part and therefore is not an area to be machined. an area to avoid if you do not wish to machine it. the safety plane. The safety plane is the plane that the tool will rise to at the end of the tool path in order to avoid collisions with the part. The safety plane contextual menu allows you to define: an offset safety plane at a distance that you give in a dialog box that is displayed, and the tool retract mode which may be either normal to the safety plane or normal to the tool axis. an upper plane which defines the highest plane that will be machined on the part, a lower plane which defines the lowest plane that will be machined on the part, a start plane which is the first plane that will be machined, an end plane which is the last plane that will be machined, the limiting contour which defines the machining limit on the part. The contour that defines the outer machining limit on the part. the offset on the part. the offset on the check element.



The picture is slightly different if you are using a rework area and will have fewer parameters.

There is also an Info button that, when pressed, gives the details on the parameters that were defined with the rework area.



You can also define the following parameters: Stop position defines where the tool stops: outside stops the tool outside the limit line, inside stops inside the limit line, on stops the tool on the limit line. Stop mode defines which part of the tool is considered at the Stop position, whether it is the contact point or the tool tip. Offset is the distance that the tool that the tool will be either inside or outside the limit line depending on the Stop mode that you chose. Part autolimit. I f you activate Part autolimit, the tool will not go beyond the edge of the part. Part autolimit and the limiting contour can be used individually or together to define the area you want to machine. In the pictures, the blue outline is the part edge, the yellow part is the area that will be machined, the black line is the limiting contour: If you use Part autolimit, the whole part is machined.






Sweeping-machining strategy

Sweeping - Machining Strategy In the machining strategy tab, you can define the tool path style, the machining tolerance, the stepover and the types of area to machine. You can also choose the tool stepover direction and distance, the tool axis and the tool advance direction. A button allows you to reverse the tool path direction. The sensitive icon illustrates the mode that you have chosen. Change the tool axis and the machining direction with Select in the contextual menu which will display a dialog box where you can choose between selection by angle and selection by coordinates. Selection by angle lets you choose the tool axis by rotation around a main axis. Angle 1 and Angle 2 are used to define the location of the tool axis around the main axis that you select. There is also a button that lets you reverse the direction of the axis with respect to the coordinate system origin.




Selection; you select a 2D element such as a line or a straight edge that will serve to define the tool axis or machining direction, Manual; you enter the XYZ coordinates, Points in the view; click on two points anywhere in the view to define the tool axis or machining direction.

The machining tab lets you: define the tool path style which can be : One-way next; the tool path always has the same direction during successive passes and goes diagonally from the end of one tool path to the beginning of the next.



One-way same; the tool path always has the same direction during successive passes and returns to the first point in each pass before moving on to the first point in the next pass. Zig-zag; the tool path alternates directions during successive passes. define the machining tolerance value, consider it to be the acceptable chord error. reverse the tool path direction. The stepover tab concerns the distance between successive passes and has two possibilities: Constant Scallop Height Constant has a constant stepover distance defined in a plane and projected onto the part. You can modify the stepover distance.



Scallop height has a stepover which depends on the scallop height that you choose. You can also define the maximum and minimum distances that can exist between passes with the scallop height that you defined.



There are three parameters in the Stepover Strategy area: Maximum distance is the stepover distance if you have selected Constant as the value or the maximum stepover distance if you chose Scallop height. Minimum distance is the minimum stepover distance if you chose Via Scallop height. Scallop height is a value that you define for the maximum allowable height of the crests of material left uncut after machining. The stepover side can be left or right and is defined with respect to the machining direction. Use Along tool axis when you want to machine along the axis you have selected (or along the default axis). Other axis can only be used with a ball-nose tool. When it is selected, the axis/direction icon lets you define a second axis (the other axis - the one pointing up to the left).

Activating Other axis displays a button for collision checking. When this is turned on, all of the points where the toolholder would have collided with the part are displayed on the tool path (after Replay).



The Machined Zone tab lets you define: which parts of the part or machining area you wish to machine: All; all of the surfaces are machined, Frontal walls; frontal surfaces of the part are machined, Lateral walls; lateral surfaces of the part are machined, Horizontal zones; horizontal surfaces of the part are machined. Min. lateral slope gives the minimum angle between the tool axis and the part surface normal for the surface to be considered to be a lateral wall. Min. frontal slope gives the minimum angle between the tool axis and the part surface normal for the surface to be considered to be a frontal wall. Max. horizontal slope gives the maximum angle between the tool axis and the part surface for the surface to be considered to be a horizontal area.


Sweeping - Macro data

Sweeping - Macro Data The Macro tab defines the tool approach, retract and plunge data as well as the parameters for high speed milling and optimization of retracts. There is a button where you can optimize retracts. This means that if no collisions are detected, the tool will not rise to the safety plane. It will only rise as high as necessary in order to clear the part. The result is a faster machining process. In some cases (where areas of the part are higher than the zone you are machining and when you are using a safety plane), the tool will cut into the part. When this happens, deactivate the Optimize retracts button. High speed milling parameters are: Transition radius is the radius of the arc that joins successive passes, Discretization angle is a value which, when reduced, gives a smoother tool path. Safety distance is the clearance distance that the tool passes over the part at the feedrate in order to disengage the tool from cutting between passes. The approach/retract mode can be: Along tool axis; the tool moves along the tool axis, Along a vector; the tool moves along a vector that you define with the Approach/Retract direction: X/Y/Z boxes, Normal; the tool moves in a direction perpendicular to the surface being machined, Tangent to movement; the approach/retract is tangent at its end to the rest of the toolpath. None; no approach/retract. Back; the tool doubles back like an arrow above the cutting tool path. You can either define this type with two lengths or a length and an angle. The parameters that you can modify are: the length (1) the height (2) the ramp angle (3).



Circular; the tool moves towards/away from the part in an arc. The parameters that you can set are: the length (1), the angle (2) the radius (3). If you do not use Part autolimit, the curve will be below the surface of the part. If you use the manual plane computation mode, the approach/retract arc will be normal to the plane that you select.

Box, the tool moves across the diagonal of an imaginary box, either in a straight line or in a curve (Linking mode). The Length(4) is the distance that the tool will move in once it has crossed the box. The box is defined by three distance values: the distance along the normal axis (1), the distance along the tangent (2) , the distance (can be a negative value) along the tool axis (3), The direction of the box diagonal is defined by whether you want to use the normal to the left or the right of the end of the tool path. Left or right is determined by looking along the tool path in the direction of the approach/retract. In the image, it is the the right side that is used. Plunges can only be defined if you selected a one-way sweeping mode in the machining strategy tab. Plunges can be : No check; the tool can plunge and rise with the surface, No plunge; the tool cannot plunge, Same height; the tool does not plunge but will not stop when it encounters a peak. In the Linking tab, check the Island skip box if you want to use intermediate approaches and retracts (i.e. those that link two different areas to machine and that are not at the beginning nor the end of the tool path).



With Island skip turned on:

With Island skip turned off:

Island skip length is the height that the tool will rise to on intermediate approaches and retracts. The Feedrate length defines the distance beyond which tool path straight lines will be replaced by intermediate approaches and retracts. In the picture below, the Feedrate length was set to 45 mm. Note that the gaps that were less than 45 mm are crossed by a straight line tool path and those that are greater than 45 mm are crossed with a standard intermediate tool path with an approach and a retract.

Feedrate length is only active if the Island skip length is 0 mm.


ZLevel machining

ZLevel Machining This task shows you how to insert a ZLevel operation into the program. ZLevel operations are finishing or semi-finishing operations that machine the whole part by parallel horizontal planes that are perpendicular to the tool axis.

ZLevel machining - geometric components

ZLevel Machining - Geometric Components In the geometric component tab you can define the area to machine either: by clicking on the face definition area and using the face selection wizard, by passing the mouse over the face definition area and choosing Body in the contextual menu if you wish to machine a whole part and not just an area on it, or by choosing a pre-defined area like this:

You can also use an Offset Group on the part. The other geometric components that you can select in the view (but that are not obligatory) are: the check element. The check is often a clamp that holds the part and therefore is not an area to be machined. an area to avoid if you do not wish to machine it (small light brown corner near the red part selection area). the safety plane which is the plane that the tool will rise to at the end of the tool path in order to avoid collisions with the part. an upper plane which defines the highest plane that will be machined on the part, a lower plane which defines the lowest plane that will be machined on the part, an imposed plane that the tool must obligatorily pass through. Use this option if the part that you are going to machine has a particular shape (a groove or a step) that you want to be sure will be cut, a start point where the tool will start cutting. Use this option when accessing the part from the outside. If you use a limiting contour that results in successive passes not being closed, the start point(s) will be ignored. the limiting contour which is the contour that defines the outer machining limit on the part. the offset on the part. the offset on the check element.







You can also define the following parameters: Stop position defines where the tool stops: outside stops the tool outside the limit line, inside stops inside the limit line, on stops the tool on the limit line. Stop mode defines which part of the tool is considered at the Stop Position, whether it is the contact point or the tool tip. Offset is the distance that the tool will be either inside or outside the limit line depending on the Stop mode that you chose. Part autolimit. If you activate Part Autolimit, the tool will not go beyond the edge of the part. Part autolimit and the limiting contour can be used individually or together to define the area you want to machine. In the pictures, the blue outline is the part edge, the yellow part is the area that will be machined, the black line is the limiting contour: If you use Part autolimit, the whole part is machined. If you use Limiting contour, only the area inside the limiting contour is machined.

If you have selected a single face to be machined and you are not using Part autolimit, the tool will machine both sides of the face. If you use Part autolimit, the tool will stop when it reaches the edge of the face (as shown below).



You can now either ix-ZLevel parameters:run the operation on the part, store the operation that you have just defined or define other parameters in the machining strategy, tool data, speeds and rates, or macro data tabs first.


ZLevel machining-machining strategy

ZLevel - Machining Strategy In the machining strategy tab, you can define the cutting mode, the machining mode, the machining tolerance and the stepover distance. You can also choose the tool axis. A button allows you to reverse the tool path direction. The sensitive icon illustrates the machining mode that you have chosen. Change the tool axis by clicking the tool in the sensitive icon and choosing Select in the contextual menu which will display a dialog box where you can choose between selection by angle and selection by coordinates. Selection by angle lets you choose the tool axis by rotation around a main axis. Angle 1 and Angle 2 are used to define the location of the tool axis around the main axis that you select. There is also a button that lets you reverse the direction of the axis with respect to the coordinate system origin.

Selection by coordinates has the following options:



Feature-defined; you select a 3D element such as a plane that will serve to automatically define the best tool axis. Selection; you select a 2D element such as a line or a straight edge that will serve to define the tool axis, Manual; you enter the XYZ coordinates, Points in the view; click on two points anywhere in the view to define the tool axis. The machining tab lets you define: the machining tolerance value, consider it to be the acceptable chord error,



the machining mode which defines the type of area to be machined and can be: By plane; the whole part is machined plane by plane, Pockets only; only pockets on the part are machined, Outer part; only the outside of the part is machined, Outer part & pockets; the whole part is machined external area by external area and pocket by pocket. the cutting mode which can be Climb or Conventional. The stepover tab concerns the distance between successive passes and has two possibilities: Constant Scallop Height



Constant has a constant stepover distance defined in a plane and projected onto the part. You can modify the stepover distance.

Scallop height has a stepover which depends on the scallop height that you choose. You can also define the maximum and minimum distance between passes with the scallop height that you defined.



The Machined Zone tab lets you define: the maximum slope that can be considered to be horizontal (any area that is considered to be horizontal will not be machined), the width of the overlap of the end of a pass over its beginning,


ZLevel machining - Macro data

ZLevel Machining - Macro Data The Macro tab defines the tool approach, retract and plunge data. There is a button where you can optimize retract distances. this means that if no obstacle is detected between two passes, the tool will not rise to the safety plane (because it is not necessary) and the operation will take less time. In some cases (where areas of the part are higher than the zone you are machining and when you are using a safety plane), the tool will cut into the part. When this happens, deactivate the Optimize retracts button. Another button lets you use high speed milling. High speed milling parameters are: Transition radius is the radius of the arc that joins successive passes, Discretization angle is a value which, when reduced, gives a smoother tool path. Safety distance is the clearance distance that the tool over over at the feedrate in order to disengage the tool from cutting between passes.


ZLevel machining - Macro data

The approach and retracts are defined with these parameters:

The linking pass (i.e. the means of moving from the end of one pass to the beginning of the next one) can be: Along tool axis; the tool moves along the tool axis, Ramping; the tool follows a slope defined by the ramping angle, Circular; the tool describes a circle defined by the value of Radius, Circular or ramping; the tool uses either circular or ramping mode depending on whichever is best adapted to the part being machined. In certain cases, notably where there is a risk of collision with a circular linking pass, you should choose Circular or ramping rather than simply Circular in order to ensure that your tool path will be produced.

Approach distance is the engagement distance for all types of linking pass. Safety distance is the distance that the tool moves horizontally before it begins its approach.


Spiral milling

Spiral Milling Spiral machining gives a good surface without having to use a particularly small tool. It gives particularly good results for areas that are relatively flat. Use this type of operation to optimize machine time by reducing the stepover. To create the operation you define: the geometry of the part to machine

,

the parameters for the machining strategy the tool to use

. The tools that can be used with this type of operation are:

end mill tools conical tools

, ,

face mill tools

and T-slotters

Either: make the Manufacturing Program current in the specification tree if you want to define an operation and the part/area to machine at the same time, or select a machining feature from the list if you have already defined the area to machine and now you want to define the operation to apply to it. Below we are going to see how to do the first of these. 1.

Spiral milling


Spiral - geometric components

Spiral Milling - Geometric Components In the geometric component tab you can define the area to machine either: by clicking on the face definition area and using the face selection wizard, by passing the mouse over the face definition area and choosing Body in the contextual menu if you wish to machine a whole part and not just an area on it, or by choosing a pre-defined area like this:

The other geometric components that you can select in the sensitive icon are: the check element. The check is often a clamp that holds the part and therefore is not an area to be machined. an area to avoid if you do not wish to machine it (light brown area in the left hand corner near the part selection area). the safety plane. The safety plane is the plane that the tool will rise to at the end of the tool path in order to avoid collisions with the part. The safety plane contextual menu allows you to: define an offset safety plane at a distance that you give in a dialog box that is displayed, remove the safety plane. a top plane which defines the highest plane that will be machined on the part,



a bottom plane which defines the lowest plane that will be machined on the part, a start point which is the first point that will be machined, an end point which is the last point that will be machined, a limiting contour which defines the machining limit on the part. The contour that defines the outer machining limit on the part. the offset on the part. the offset on the check element. You can also define the following parameters: Stop position defines where the tool stops: outside stops the tool outside the limit line, inside stops inside the limit line, on stops the tool on the limit line. Stop mode defines which part of the tool is considered at the Stop Position, whether it is the contact point or the tool end. Offset is the distance that the tool that the tool will be either inside or outside the limit line depending on the Stop mode that you chose. Part autolimit. If you activate Part autolimit, the tool will not go beyond the edge of the part. http://dsfr2e/itprm/doc/CXR7doc/doc/online/smgug/smgugbt0234.htm (2 of 3) [5/17/2001 3:11:34 PM]


Part autolimit and the limiting contour can be used individually or together to define the area you want to machine. In the pictures, the blue outline is the part edge, the yellow part is the area that will be machined, the black line is the limiting contour: If you use Part autolimit, the whole part is machined.




Spiral - machining strategy

Spiral Milling - Machining Strategy The machining strategy tab is where you define the machining and strategy parameters and also the area that you want to machine. Start by selecting what you want to machine with one of the two options: automatic; the surfaces that are considered to be horizontal with respect to the maximum angle are automatically selected for machining. or manual. A red contour lights up in the sensitive icon. Click on it and then select the contours that will form the limit to the area you want to machine. The selection takes account of all the surfaces inside the limit, horizontal or not. You can also define more than one contour. Defining another contour inside the original contour will have the effect that only the area between the two contours (i.e. inside one and outside the other) will be machined. The blue contour represents the first contour, the black contour represents the second contour, and the yellow area represents what will be machined. There are three tabs: Machining, Stepover, Zone, HSM (High Speed Milling). You can also change the tool axis with Select in the contextual menu which will display a dialog box where you can choose between selection by angle and selection by coordinates. Selection by angle lets you choose the tool axis by rotation around a main axis. Angle 1 and Angle 2 are used to define the location of the tool axis around the main axis that you select. There is also a button that lets you reverse the direction of the axis with respect to the coordinate system origin.




Feature-defined; you select a 3D element such as a plane that will serve to automatically define the best tool axis. Selection; you select a 2D element such as a line or a straight edge that will serve to define the tool axis, Manual; you enter the XYZ coordinates, Points in the view; click on two points anywhere in the view to define the tool axis.



The machining tab lets you define: the cutting mode which can be Climb or Conventional, the tool offset with respect to the contour, the machining tolerance value, consider it to be the acceptable chord error. the tool path style: With Outward, the tool path will begin at the middle of the area to machine and work outwards.

With Inward, the tool path will begin at the outer limit of the area to machine and work inwards.

You can also reverse the tool path. Reversing the tool path means that a tool path that goes from right to left will now go from left to right and vice versa.



The stepover tab lets you define the maximum distance between successive passes in the tool path.

At the bottom of the stepover tab are the View Direction buttons. View direction is used to calculate the stepover distance, as if you were looking along an axis. If you wish to use an axis other than the tool axis to define the stepover, select Other axis. Other axis can only be used with a ball-nose tool. When Other axis is active, there is a box is also displayed where you can choose to check for toolholder-part collisions. The icon at the top of the tab for axis selection has changed and you can now select an axis (the oblique axis in the icon) other than the tool axis for the view direction.



In the Zone tab, you can define the maximum angle that can be considered as horizontal. The angle is measured perpendicular to the tool path.

If you choose to perform high speed milling, you can define the corner radius to round the ends of passes. The ends are rounded to give a smoother path that is machined much faster.


Spiral - Macro data

Spiral Milling - Macro Data The Macro tab defines the tool approach and retract data. The approach/retract mode can be: along tool axis; the tool moves along the tool axis, along a vector; the tool moves along a vector that you define with the Approach/Retract direction: X/Y/Z boxes, normal; the tool moves in a direction perpendicular to the surface being machined, tangent to movement; the approach/retract is tangent at its end to the rest of the tool path. none; no approach/retract.


Spiral - Macro data

back; the tool doubles back like an arrow above the cutting tool path. You can either define this type with two lengths or a length and an angle. The parameters that you can modify are: the length (1) the height (2) the ramp angle (3). circular; the tool moves towards/away from the part in an arc. The parameters that you can set are: the length (1), the angle (2) the radius (3). If you do not use Part autolimit, the curve will be below the surface of the part. If you use the manual plane computation mode, the approach/retract


Spiral - Macro data

arc will be normal to the plane that you select. box, the tool moves across the diagonal of an imaginary box, either in a straight line or in a curve (Linking mode). The Length(4) is the distance that the tool will move in once it has crossed the box. The box is defined by three distance values: the distance along the normal axis (1), the distance along the tangent (2), the distance (can be a negative value) along the tool axis (3), The direction of the box diagonal is defined by whether you want to use the normal to the left or the right of the


Spiral - Macro data

end of the tool path. Left or right is determined by looking along the tool path in the direction of the approach/retract. In the image, it is the the right side that is used.


Contour-driven machining

Contour-driven Machining This task explains how to machine an area on a part by using a contour as guide. There are three types of machining included in this task: parallel contours where the tool sweeps out an area by following progressively distant (or closer) parallel offsets of a given guide contour. between contours where the tool sweeps between two guide contours along a tool path that is obtained by interpolating between the guide contours. The ends of each pass lie on two stop contours. spine contour where the tool sweeps across a contour in perpendicular planes.

To create the operation, you define: the geometry of the part to machine

,

the parameters of the machining strategy the tool to use this operation,

; you have the choice of end mill


, or conical

tools for

,

.

Only the geometry and the guide contour(s) (strategy tab) are obligatory. All of the other requirements have a default value Either: make the Manufacturing Program current in the specification tree if you want to define an operation and the part/area to machine at the same time, or select a machining feature from the list if you have already defined the area to machine and now you want to define the operation to apply to it. Below we are going to see how to do the first of these with a between contours operation on a small area of a part. Open file Basic2.CATPart, then select NC Manufacturing > Surface Machining in the Start menu.

4.

Press Replay to compute the tool path for the operation.




The result will show you that you have machined between two guide contours delimited at either end by two others.




Contour-driven - geometric components

Contour-driven Machining - Geometric Components In the geometric component tab you can define the area to machine either: by clicking on the face definition area and using the face selection wizard, by passing the mouse over the face definition area and choosing Body in the contextual menu if you wish to machine a whole part and not just an area on it, or by choosing a pre-defined area like this:

You can also use an Offset Group on the part. The other geometric components that you can select in the sensitive icon are: the guide contours, the stop contours (only used for machining with parallel contours), the check element. The check is often a clamp that holds the part and therefore is not an area to be machined. an area to avoid if you do not wish to machine it (light brown area in the left hand corner near the part selection area). the safety plane. The safety plane is the plane that the tool will rise to at the end of the tool path in order to avoid collisions with the part. The safety plane contextual menu allows you to define: an offset safety plane at a distance that you give in a dialog box that is displayed, http://dsfr2e/itprm/doc/CXR7doc/doc/online/smgug/smgugbt0233.htm (1 of 4) [5/17/2001 3:12:37 PM]


and the tool retract mode which may be either normal to the safety plane or normal to the tool axis. an upper plane which defines the highest plane that will be machined on the part, a lower plane which defines the lowest plane that will be machined on the part, a limiting contour which defines the machining limit on the part. The contour that defines the outer machining limit on the part. the offset on the part. the offset on the check element.

The picture is slightly different if you are using a rework area and will have fewer parameters. There is also an Info button that, when pressed, gives the details on the parameters that were defined with the rework area.



You can also define the following parameters: Stop position defines where the tool stops: outside stops the tool outside the limit line, inside stops inside the limit line, on stops the tool on the limit line. Stop mode defines which part of the tool is considered at the Stop Position, whether it is the contact point or the tool end. Offset is the distance that the tool that the tool will be either inside or outside the limit line depending on the Stop mode that you chose. Part autolimit. If you activate Part autolimit, the tool will not go beyond the edge of the part. Part autolimit and the limiting contour can be used individually or together to define the area you want to machine. In the pictures, the blue outline is the part edge, the yellow part is the area that will be machined, the black line is the limiting contour: If you use Part autolimit, the whole part is machined.






Contour-driven - machining strategy

Contour-driven Machining - Machining Strategy In the machining strategy tab, you can define the machining, strategy and stepover parameters and the zone to machine. You should choose the cycle type (between contours, parallel contour or spine contour) that you want before setting any of the other parameters. The parameters that you can use depend on the cycle type you choose.

Between Contours The Between contours option has four active tabs: Machining, Strategy, Stepover, Machined Zone. First choose whether you want to machine: between four open contours (i.e. that are not necessarily perfectly connected to each other) Guide 1 and Guide 2 are the two contours between which you are going to machine. Stop 1 and Stop 2 delimit the ends of the machining paths.



or by machining or within one closed contour. To do this you must select four points on the contour and you must select them in the order that you see in the sensitive icon. P1, P2, P3 and P4 are the four points that you select on the contour within which you are going to machine.

You can also change the tool axis with Select in the contextual menu which will display a dialog box where you can choose between selection by angle and selection by coordinates. Selection by angle lets you choose the tool axis by rotation around a main axis. Angle 1 and Angle 2 are used to define the location of the tool axis around the main axis that you select. There is also a button that lets you reverse the direction of the axis with respect to the coordinate system origin.




Feature-defined; you select a 3D element such as a plane that will serve to automatically define the best tool axis. Selection; you select a 2D element such as a line or a straight edge that will serve to define the tool axis, Manual; you enter the XYZ coordinates, Points in the view; click on two points anywhere in the view to define the tool axis. The machining tab lets you: define the tool path style which can be: One-way next; the tool path always has the same direction during successive passes and goes diagonally from the end of one tool path to the beginning of the next. One-way same; the tool path always has the same direction during successive passes and returns to the first point in each pass before moving on to the first point in the next pass. Zig-zag; the tool path alternates directions during successive passes. define the machining tolerance value, consider it to be the acceptable chord error. reverse the tool path direction.



The strategy tab has an option that lets you start an automatic pencil operation (defined with a set of default parameters) at the end of the contour driven operation.

There are four stepover possibilities: Constant, Scallop height, Constant on part, Maximum on part.

Constant has a maximum stepover distance defined in a plane and projected onto the part. You can modify the stepover distance.






Constant on part is a stepover that has a constant distance on the part itself. The parameters that you can define are: the distance; the constant distance between two successive passes, The sweeping strategy, i.e. where you want to start machining and where you want to end, the possibilities are: From guide 1 to guide 2 (starts at guide 1 and ends at guide 2) From guide 2 to guide 1 (starts at guide 2 and ends at guide 1), From guide to zone center (starts at guide 1 and works towards the center of the zone then goes to guide 2 and works towards the center of the zone), From zone center to guide (starts at the center of the zone and works towards guide 1 then comes back to the center and works towards guide 2), From guide to zone center (spiral) starts at guide 1 and spirals towards the center), From zone center to guide (spiral) starts at the center and sprials towards the guide contours), the tool initial position with respect to the guide contour (inside, outside, on), the tool reference; whether the tool end or the tool contact point is used for the computation, the tool offset with respect to the guide contour. With a negative value the tool path will start outside the guide contour, with a positive value it will start inside the guide contour. Below is an example of Constant on part use.



The stepover is of a constant distance along the whole length of the path measured on the part itself, starting from Guide 1 and going towards Guide 2.





Maximum on part defines the stepover with a maximum distance between passes that must be respected. The parameters that you can define are: the maximum distance; the constant distance between two successive passes, The sweeping strategy, i.e. where you want to start machining and where you want to end, the possibilities are: From guide 1 to guide 2 (starts at guide 1 and ends at guide 2) From guide 2 to guide 1 (starts at guide 2 and ends at guide 1), From guide to zone center (starts at guide 1 and works towards the center of the zone then goes to guide 2 and works towards the center of the zone), From zone center to guide (starts at the center of the zone and works towards guide 1 then comes back to the center and works towards guide 2), From guide to zone center (spiral) starts at guide 1 and spirals towards the center), From zone center to guide (spiral) starts at the center and spirals towards the guide contours), the tool initial position with respect to the guide contour (inside, outside, on), the tool reference; whether the tool end or the tool contact point is used for the computation, the tool offset with respect to the guide contour. With a negative value the tool path will start outside the guide contour, with a positive value it will start inside the guide contour.



Below is an example to illustrate the difference between Constant on part and Maximum on part. We are going to take the same part and use the same parameters and then look at the results. This is the surface we are going to use

When we use Constant on part the result is of an equal distance on the part surface from guide 1 to guide 2. Note the bottom of the machined area and how the paths remain perfectly parallel to each other but because of the shape of the surface they finish gradually on guide 2.



Now see the difference when we use Maximum on part. There is a variation in the distance between the paths on the surface but the paths respect both guide 1 and guide 2. There is no gradual finish on Guide 2 as there was with Constant on part.

At the bottom of the stepover tab are the View Direction buttons. View direction is used to calculate the stepover distance, as if you were looking along an axis. If you wish to use an axis other than the tool axis to define the stepover, select Other axis. Other axis can only be used with a ball-nose tool. When Other axis is active, there is a box is also displayed where you can choose to check for toolholder-part collisions. The icon at the top of the tab for axis selection has changed and you can now select an axis (the oblique axis in the icon) other than the tool axis for the view direction.

Here is an example of View direction use:



This is the surface that we are going to machine:

Taking this surface, using a distance of 5, Constant stepover and with this edge (red edge) defined as the other axis:

will give you this result:



This is what you get using a distance of 5, Constant stepover and along the tool axis:

However if you look along the tool axis you will see how the same distance is used for the stepover as in the first operation:

The Machined Zone parameters are used to define the type of area on the part that you wish to machine: All; all of the surfaces are machined, Frontal walls; frontal surfaces of the part are machined, Lateral walls; lateral surfaces of the part are machined, Horizontal zones; horizontal surfaces of the part are machined. Below the zone selection area are parameters which let you define whether a surface is frontal, lateral or horizontal: Min. lateral slope gives the minimum angle between the tool axis and the part surface normal for the surface to be considered to be a lateral wall. http://dsfr2e/itprm/doc/CXR7doc/doc/online/smgug/smgugbt0213.htm (13 of 29) [5/17/2001 3:12:49 PM]


Min. frontal slope gives the minimum angle between the tool axis and the part surface normal for the surface to be considered to be a frontal wall. Max. horizontal slope gives the maximum angle between the tool axis and the part surface normal for the surface to be considered to be a horizontal area.

Parallel Contours The Parallel contour option has four active tabs: Machining, Strategy, Stepover, Machined Zone. You must choose a contour on the part to be the reference for your operation.







Feature-defined; you select a 3D element such as a plane that will serve to automatically define the best tool axis. Selection; you select a 2D element such as a line or a straight edge that will serve to define the tool axis, Manual; you enter the XYZ coordinates, Points in the view; click on two points anywhere in the view to define the tool axis. The machining tab lets you: define the tool path style which can be : One-way next; the tool path always has the same direction during successive passes and goes diagonally from the end of one tool path to the beginning of the next. One-way same; the tool path always has the same direction during successive passes and returns to the first point in each pass before moving on to the first point in the next pass. Zig-zag; the tool path alternates directions during successive passes. define the machining tolerance value, consider it to be the acceptable chord error. reverse the tool path direction.



The strategy tab has parameters that concern the tool position and distance: Pencil rework lets you start an automatic pencil operation (defined with a set of default parameters) at the end of the contour-driven operation, Offset on contour is the distance the tool will be from the guide contour at the beginning of the operation Maximum width to machine defines the width of the area to machine starting from the guide contour, Offset side defines the side of the contour where machining will be performed (left or right), i.e. if you choose Left, the tool will machine on the left side of the guide contour for the Maximum width distance, Direction is the machining direction, either towards the contour (starting at the Maximum width distance from the guide contour) or away from the contour. Initial tool position is where the tool will start with respect to the guide contour (in red); it can be: to (1) on (2) past (3) There is also an option that lets you start an automatic pencil operation (defined with a set of default parameters) at the end of the contour driven operation.

There are two stepover possibilities: Constant, Scallop height.







At the bottom of the stepover tab are the View Direction buttons. View direction is used to calculate the stepover distance, as if you were looking along an axis. If you wish to use an axis other than the tool axis to define the stepover, select Other axis. Other axis can only be used with a ball-nose tool. When Other axis is active, there is a box is also displayed where you can choose to check for toolholder-part collisions.



The icon at the top of the tab for axis selection has changed and you can now select an axis (the oblique axis in the icon) other than the tool axis for the view direction.











The Zone parameters are used to define the type of area on the part that you wish to machine: All; all of the surfaces are machined, Frontal walls; frontal surfaces of the part are machined, Lateral walls; lateral surfaces of the part are machined, Horizontal zones; horizontal surfaces of the part are machined. Below the zone selection area are parameters which let you define whether a surface is frontal, lateral or horizontal: Min. lateral slope gives the minimum angle between the tool axis and the part surface normal for the surface to be considered to be a lateral wall. Min. frontal slope gives the minimum angle between the tool axis and the part surface normal for the surface to be considered to be a frontal wall. Max. horizontal slope gives the maximum angle between the tool axis and the part surface normal for the surface to be considered to be a horizontal area.

Spine Contour The Spine contour option has three active tabs: Machining, Stepover, Machined Zone.



You must choose a contour on the part to be the reference for your operation.





Feature-defined; you select a 3D element such as a plane that will serve to automatically define the best tool axis. Selection; you select a 2D element such as a line or a straight edge that will serve to define the tool axis, Manual; you enter the XYZ coordinates, Points in the view; click on two points anywhere in the view to define the tool axis. The machining tab lets you: define the tool path style which can be : One-way next; the tool path always has the same direction during successive passes and goes diagonally from the end of one tool path to the beginning of the next. One-way same; the tool path always has the same direction during successive passes and returns to the first point in each pass before moving on to the first point in the next pass. Zig-zag; the tool path alternates directions during successive passes. define the machining tolerance value, consider it to be the acceptable chord error. reverse the tool path direction.



There are two stepover possibilities: Constant, Scallop height.





At the bottom of the stepover tab are the View Direction buttons. View direction is used to calculate the stepover distance, as if you were looking along an axis. If you wish to use an axis other than the tool axis to define the stepover, select Other axis. Other axis can only be used with a ball-nose tool. When Other axis is active, there is a box is also displayed where you can choose to check for toolholder-part collisions.



The icon at the top of the tab for axis selection has changed and you can now select an axis (the oblique axis in the icon) other than the tool axis for the view direction.











The zone parameters are used to define the type of area on the part that you wish to machine: All; all of the surfaces are machined, Frontal walls; frontal surfaces of the part are machined, Lateral walls; lateral surfaces of the part are machined, Horizontal zones; horizontal surfaces of the part are machined. Below the zone selection area are parameters which let you define whether a surface is frontal, lateral or horizontal: Min. lateral slope gives the minimum angle between the tool axis and the part surface normal for the surface to be considered to be a lateral wall. Min. frontal slope gives the minimum angle between the tool axis and the part surface normal for the surface to be considered to be a frontal wall. Max. horizontal slope gives the maximum angle between the tool axis and the part surface normal for the surface to be considered to be a horizontal area.


Contour-driven - Macro data

Contour-driven Machining - Macro Data The Macro tab defines the tool approach and retract data. There is a button where you can optimize retracts. This means that if no collisions are detected, the tool will not rise to the safety plane. It will only rise as high as necessary in order to clear the part. The result is a faster machining process. In some cases (where areas of the part are higher than the zone you are machining and when you are using a safety plane), the tool will cut into the part. When this happens, deactivate the Optimize retracts button. High speed milling parameters are: Transition radius is the radius of the arc that joins successive passes, Discretization angle is a value which, when reduced, gives a smoother tool path. Safety distance is the clearance distance that the tool over over at the feedrate in order to disengage the tool from cutting between passes The approach/retract mode can be: along tool axis; the tool moves along the tool axis, along a vector; the tool moves along a vector that you define with the Approach/Retract direction: X/Y/Z boxes, normal; the tool moves in a direction perpendicular to the surface being machined, tangent to movement; the approach/retract is tangent at its end to the rest of the tool path. and none; no approach/retract.



Back; the tool doubles back like an arrow above the cutting tool path. You can either define this type with two lengths or a length and an angle. The parameters that you can modify are: the length (1) the height (2) the ramp angle (3).

Circular; the tool moves towards/away from the part in an arc. The parameters that you can set are: the length (1), the angle (2) the radius (3). If you do not use Part autolimit, the curve will be below the surface of the part. If you use the manual plane computation mode, the approach/retract arc will be normal to the plane that you select.



Box, the tool moves across the diagonal of an imaginary box, either in a straight line or in a curve (Linking mode). The Length(4) is the distance that the tool will move in once it has crossed the box. The box is defined by three distance values: the distance along the normal axis (1), the distance along the tangent (2), the distance (can be a negative value) along the tool axis (3), The direction of the box diagonal is defined by whether you want to use the normal to the left or the right of the end of the tool path. Left or right is determined by looking along the tool path in the direction of the approach/retract. In the image, it is the the right side that is used. In the Linking tab, check the Island skip box if you want to use intermediate approaches and retracts (i.e. those that link two different areas to machine and that are not at the beginning nor the end of the tool path).



With Island skip turned on:

With Island skip turned off:

Island skip length is the height that the tool will rise to on intermediate approaches and retracts. The Feedrate length defines the distance beyond which tool path straight lines will be replaced by intermediate approaches and retracts. In the picture below, the Feedrate length was set to 45 mm. Note that the gaps that were less than 45 mm are crossed by a straight line tool path and those that are greater than 45 mm are crossed with a standard intermediate tool path with an approach and a retract.

Feedrate length is only active if the Island skip length is 0 mm. Your guide contour(s) must be closed.


Contouring

Create a Profile Contouring Operation This task explains how to create a profile contouring operation on a part. A profile contouring operation can be created from machining: Between two planes The tool follows a contour between the top and bottom planes while respecting user-defined geometry limitations and machining strategy parameters. Between two curves The tool follows the trajectory defined by the top and bottom guide curves while respecting user-defined geometry limitations and machining strategy parameters. Between a curve and surfaces The tool follows a trajectory defined by a top guide curve and the bottom surfaces while respecting user-defined geometry limitations and machining strategy parameters.

Select the Strategy tab page

and choose the

desired tool path style. You can then use the tab pages to set parameters for: machining such as machining tolerance stepover (see example) finishing.

You can choose between the standard tip output and a cutter profile output by means of the Output type option in the Machining tab page. If a cutter profile style is selected, both the tip and cutter profile will be visualized during tool path replay. For cutter profile, cutter compensation instructions are generated in the NC data output. In this case, an approach macro must be defined to allow the compensation to be applied. For macro types other than approach and retract, the compensation is not applied: these macros will be framed with CUTCOM/OFF and CUTCOM /left/right instructions. Any user defined PP words in macros are added to the cutter compensation instructions generated in the NC data output. Therefore you should be careful when specifying CUTCOM instructions in macros. A tool is proposed by default when you want to create a machining operation. If the proposed tool is not suitable, just select the Tool tab page to specify the tool you want to use. This is described in Edit the Tool of an Operation. 9.

Select the Feeds and Speeds tab page

to specify the feedrates and spindle speeds for the operation.



10.

Check the validity of the operation by replaying the tool path.

The specified operation uses a default linking macro to avoid collision with the selected fixture. You can optimize the linking macro and add approach and retract macros to the operation in the Macros tab page . This is described in Define Macros of a Milling Operation. 11.

Click OK to create the operation.


Reworking operations

Reworking Operations These are the operations that you will use to rework an area on a part where there is residual material. Before using one of these operations, compute the areas that you want to rework. Pencil operations Reworking operations


Pencil operations

Pencil Operations This task shows you how to insert a pencil operation into the program. A pencil operation is one where the tool remains tangent in two places to the surface to be machined during the cycle. It is often used to remove crests along the intersection of two surfaces that were left behind by a previous operation. To create the operation you define: the geometry of the part to machine

,

the parameters of the machining strategy

,

the tool to use ; you have the choice of end mill for this operation, the feedrates and spindle speeds, the macros

or conical

tools

.

Only the geometry is obligatory, all of the other parameters have a default value. Either: make the Manufacturing Program current in the specification tree if you want to define an operation and the part/area to machine at the same time, or select a machining feature from the list if you have already defined the area to machine and now you want to define the operation to apply to it. Below we are going to see how to do the first of these. 1. Open file gets2.CATPart. A Pencil entity and a default tool are added to the program. Select the Pencil icon

.

The dialog box opens at the geometry page

.

This page includes a sensitive icon to help you specify the geometry to be machined.

Pencil operations


Pencil - geometric components

Pencil - Geometric Components In the geometric component tab you can define the area to machine either: by clicking on the face definition area and using the face selection wizard, by passing the mouse over the face definition area and choosing Body in the contextual menu if you wish to machine a whole part and not just an area on it, or by choosing a pre-defined area like this:

You can also use an Offset Group on the part. The other geometric components that you can select in the view (but that are not obligatory) are: the check element. The check is often a clamp that holds the part and therefore is not an area to be machined. an area to avoid if you do not wish to machine it (light brown area in the corner near part selection). the safety plane. The safety plane is the plane that the tool will rise to at the end of the tool path in order to avoid collisions with the part. The safety plane contextual menu allows you to define: an offset safety plane at a distance that you give in a dialog box that is displayed, and the tool retract mode which may be either normal to the safety plane or normal to the tool axis. the limiting contour which defines the outer machining limit on the part. the offset on the part. the offset on the check element.







You can also define the following parameters: Stop position defines where the tool stops: outside stops the tool outside the limit line, inside stops inside the limit line, on stops the tool on the limit line. Stop mode defines which part of the tool is considered at the Stop position, whether it is the contact point or the tool tip. Offset is the distance that the tool that the tool will be either inside or outside the limit line depending on the Stop mode that you chose. Part autolimit. If you activate Part autolimit, the tool will not go beyond the edge of the part.

Part autolimit and the limiting contour can be used individually or together to define the area you want to machine. In the pictures, the blue outline is the part edge, the yellow part is the area that will be machined, the black line is the limiting contour: If you use Part autolimit, the whole part is machined.






Pencil - machining strategy

Pencil - Machining Strategy In the machining strategy tab, you can define the machining tolerance, the cutting mode the axial direction, the minimum change length and the size of the smallest areas to be machined. You can also choose the tool axis. The sensitive icon illustrates a pencil tool path, i.e. one that is tangent to two surfaces at the same time. In the sensitive icon you can change the tool axis via Select in the contextual menu which will display a dialog box where you can choose between selection by angle and selection by coordinates. Selection by angle lets you choose the tool axis by rotation around a main axis. Angle 1 and Angle 2 are used to define the location of the tool axis around the main axis that you select. There is also a button that lets you reverse the direction of the axis with respect to the coordinate system origin.




Selection; you select a 2D element such as a line or a straight edge that will serve to define the tool axis, Manual; you enter the XYZ coordinates, Points in the view; click on two points anywhere in the view to define the tool axis.

I

In the machining tab, consider the machining tolerance value to be the acceptable chord error. There is also a button that reverses the tool path direction.



The axial direction can be: up, down or either. Either means that the direction which is most suitable to the current cutting action will be used. The cutting mode can be: Conventional where the back of the advancing tool cuts into the material first, Climb where the front of the advancing tool cuts into the material first, Either where either of the two possibilities may be used depending on which is most suitable to the current cutting action. Minimum change length is the minimum distance for a change of axial direction or cutting mode, i.e. if a portion of the pass is shorter than this value, the tool will ignore it and continue in the same direction or mode.


Pencil - Macro data

Pencil - Macro Data The Macro tab defines the tool approach and retract data.

There is a button where you can optimize retract distances. this means that if no obstacle is detected between two passes, the tool will not rise to the safety plane (because it is not necessary) and the operation will take less time. There is a button where you can optimize retracts. This means that if no collisions are detected, the tool will not rise to the safety plane. It will only rise as high as necessary in order to clear the part. The result is a faster machining process. The approach/retract mode can be: along tool axis; the tool moves along the tool axis for a given Length, along a vector; the tool moves along a vector that you define with the X,Y and Z directions for a given Length, normal; the tool moves in a direction perpendicular to the surface being machined for a given Length, tangent to movement; the approach/retract is tangent at its end to the rest of the tool path and is of a given Length, and none; no approach/retract.


Pencil - Macro data

Back; the tool doubles back like an arrow above the cutting tool path. You can either define this type with two lengths or a length and an angle. The parameters that you can modify are: the length (1) the height (2) the ramp angle (3). Circular; the tool moves towards/away from the part in an arc. The parameters that you can set are: the length (1), the angle (2) the radius (3). If you do not use Part autolimit, the curve will be below the surface of the part. If you use the manual plane computation mode, the approach/retract arc will be http://dsfr2e/itprm/doc/CXR7doc/doc/online/smgug/smgugbt0331.htm (2 of 4) [5/17/2001 3:15:52 PM]

normal to the plane that you select. Box, the tool moves across the diagonal of an imaginary box, either in a straight line or in a curve (Linking mode). The Length(4) is the distance that the tool will move in once it has crossed the box. The box is defined by three distance values: the distance along the normal axis (1), the distance along the tangent (2), the distance (can be a negative value) along the tool axis (3), The direction of the box diagonal is defined by whether you want to use the normal to

the left or the right of the end of the tool path. Left or right is determined by looking along the tool path in the direction of the approach/retract. In the image, it is the the right side that is used.


Roughing rework

Roughing Rework Operations This task explains how to rework a part. You must have computed at least one machining operation prior to this one in the manufacturing program. The rough stock used for a program where you insert a reworking operation must be topologically closed, that is, it cannot be formed by a set of faces. 1. 2.

Select the roughing icon

.

In the geometric component tab, define the area to machine either: by clicking on the face definition area and using the face selection wizard. or by passing the mouse over the face definition area and choosing Body in the contextual menu. Do not define the rough stock for this operation. The residual material that is left by the operations preceding the reworking is automatically taken as the rough stock for the operation. The other geometric components that you can select in the view (but that are not obligatory) are: the check element. The check is often a clamp that holds the part and therefore is not an area to be machined. the safety plane. The safety plane is the plane that the tool will rise to at the end of the tool path in order to avoid collisions with the part. an upper plane which defines the highest plane that will be machined on the part, a lower plane which defines the lowest plane that will be machined on the part, an imposed plane that the tool must obligatorily pass through. Use this option if the part that you are going to machine has a particular shape (a groove or a step) that you want to be sure will be cut, a start point where the tool will start cutting. Use this option when accessing the part from the outside an inner point where the tool will start cutting. This option is used when machining pockets. the offset on the part. the offset on the check element.

Machining features

Machining Features Machining features are areas that you define on a part. You may want to define an area where you want to use a specific type of operation or you may want to define an area to rework because there is too much residual material on the part. Besides this, you can also decide to define a specific offset on an area of a part or a group of varied offsets on a part. Area to machine Area to rework Offset area Group of offset areas


Defining an area to machine

Defining an Area to Machine Machining areas can be used to define different zones on a part. First you define the machining areas and then you assign an operation to each of them. This is a useful approach if, before you start machining, you are aware that the part has areas that will require different types of operation. A machining area can be: the whole part (for example, in roughing), a subset of the faces on the part, a subset of faces on the part with a limiting contour. 1.

Click OK. This creates a machining area. When you want to assign an operation to one of these areas, simply click on its name in the Manufacturing feature view and then click the icon for the operation that you want to use.

7.

The operation dialog box opens at the machining strategy tab and not the geometric components tab because the area to machine is already defined. The area is displayed in blue on the part in the viewer. If you want to edit a machining area, double click on its name in the Manufacturing feature view.


Defining an area to rework

Defining an Area to Rework Once you have machined a part and visually checked it, you may decide to rework certain areas where residual material remains. Defining a rework area allows you to focus only on the areas where there is residual material and this gain time. This task explains how to define an area to rework and how to use it. Before creating a rework area you must have executed a manufacturing program. 1.

Open gets2.CATPart.

2.

. Click the Rework Area icon In the dialog box that is displayed, change the Entry diameter to 10 mm, the Corner radius to 5 mm and the name to Rework.



3.

Press OK to compute the rework area.

The rework area is created and can be seen in the Manufacturing feature view .

The following steps are not obligatory.



4.

There is a Load from button at the top of the dialog box that can be used to simplify the creation of a rework area by loading all of the appropriate data from an existing operation, tool or area. Click on the button and then select an operation and/or a tool in the specifications tree and/or select a machining area in the manufacturing view.

5.

In the General tab, click the red area and either: use the face selection wizard to choose the faces that you want to make up the area to machine. or pass the mouse over the face definition area and choosing Body in the contextual menu if you wish to machine a whole part and not just an area on it. Define the limit line in order to restrict the area to be reworked. Select the tool axis that you used to machine the rest of the part. Enter the tool data that you used to machine the rest of the part. If you wish to use a conical tool, enter a positive cutting angle. For an end mill, leave the default value of 0 degrees.

6. 7.

Press Compute. If you find that there are too many areas to be reworked or if you decide to concentrate on only a part of the rework area, go to the Advanced tab and define other parameters to restrict the area to rework.



You can use a filter line to define a smaller area, and the minimum depth, length and width parameters to filter out areas that you wish to ignore because they are not deep, long or wide enough. Tolerance is the machining tolerance that you want to use for the rework area. For the sake of speed you should use the same value as for the machining tolerance in the operation that the rework area is going to be used in. You may decide to use a smaller tolerance in the machining area and a larger one in the operation, reducing the operation one until you obtain satisfactory results as regards the finish that you require. Overlap is the distance that you allow the tool to go beyond the boundaries of the rework area and is defined as a percentage of the tool radius. Part offset is the offset that is computed for the rework area with respect to the part. 8.

Click Compute to create a rework area. Press OK to close the dialog box.



9.

When you want to assign an operation to a rework area, simply click on its name in the Manufacturing feature view and then click the icon for the operation that you want to use. The operation dialog box opens at the machining strategy tab and not the geometric components tab because the area to machine is already defined. The area is displayed in blue on the part in the viewer. If you want to edit a rework area, double click on its name in the Manufacturing feature view.


Defining offsets

Defining offsets This task shows you how to define offset areas and groups of offset areas. An offset area must belong to a group of offset areas. An offset area is a group of faces (at least one) with a n offset value (with respect to the original part) and a color to identify it. An Offset group must include at least one offset area. Offset groups can be used to machine upper and lower dies using a single set of geometry.

1. 2.

Open file Basic1.CATPart then select NC Manufacturing > Surface Machining in the Start menu. Click the Offset group icon

.

In the dialog box that is displayed, change the name of the group to Group1 and press OK.

Offset in the dialog box is the overall offset that will be applied to the group in general. It is applied only to areas in the offset group that do not have their own specific offset. For example, if you assign an offset of 10 mm to a group and within that group there is an area that has a thickness of 5 mm and an area that has no thickness assigned to it, the first area will still have an offset of 5mm and the second area will have an offset of 10 mm.


Defining offsets

Open the manufacturing view and you will see that the group has been created.

3.

As Group1 is still the current object, you are going to create two offset areas there. Click the Offset area icon A dialog box is displayed.

.

Enter a value of 10 mm for the thickness and leave green as the color you want to display the offset area in.

The thickness of the offset can be negative. If you want to use a negative value, the tool corner radius must be greater than 2mm.


Defining offsets

4.

Click on the red area in the dialog box and select these three faces in the viewer:

Click OK in the Face Selection wizard. Click OK in the Offset Area creation dialog box. 5.

Click on the Offset Area creation icon again. This time enter a thickness of 20 mm and change the color.


Defining offsets

6.

Click on the red area in the dialog box and select these two faces in the viewer.

Click OK in the Face Selection wizard. Click OK in the Offset Area creation dialog box. So now you have Group 1 containing two areas, one with an offset of 10 mm and the other with an offset of 20 mm.


Defining offsets

7. Click the Sweeping icon

.

At the top of the geometry tab, select Group1 as Offset Group. Offset groups can be used with Sweeping, Pencil and Contour-driven operations. They can also be used with rework areas. If you are using a rework area that includes an offset group in an operation, you will not be able to modify the offset group. 8.

Using MB3 over the red area, choose Body(ies) in the contextual menu and click on the part in the viewer. Double click anywhere in the viewer to confirm your selection and redisplay the dialog box. Press Replay.

Note the effect of the two offset areas (on the left in the picture.) The same face cannot be used in two separate offset areas in the same group. If you wish to have two different offsets on any given face, you must create a new group for the second value.

PP Word Syntaxes

PP Word Syntaxes This section shows you how to customize the following types of syntaxes in your PP word table: syntaxes associated to NC commands sequences of PP word syntaxes associated to NC instructions. The NC Manufacturing product will resolve the parameters of these syntaxes and syntax sequences and generate the corresponding statements in the APT output. A sample PP word table is delivered with the product in \Startup\Manufacturing\PPTables\PPTableSample.pptable It can be used as a basis for creating user-defined tables. Please refer to PP Tables and Word Syntaxes for more information.

1.

NC Commands You can define for a given machine tool (i.e. post-processor) PP word syntaxes associated to particular NC commands. An NC command is a machine function such as feedrate declaration (NC_FEEDRATE) or spindle activation (NC_SPINDLE_START). A syntax comprises a major word and one or more syntax elements such as minor words, numerical values, list values and parameters. A syntax that includes lists or parameters is a parameterized syntax (see example below): *START_NC_COMMAND NC_FEEDRATE FEDRAT/%MFG_FEED_VALUE,&MFG_FEED_UNIT *END Note that the `&' character indicates a list and the `%' character indicates a parameter.

2.

3. 4.

You can define only one syntax for each NC command. The following example shows how the NC command NC_DELAY could be used in a Drilling Dwell Delay operation. Make sure that the PP word table is referenced by the machine used in the Part Operation and the syntax associated with the NC_DELAY command is already created as follows: *START_NC_COMMAND NC_DELAY DELAY/&MFG_DELAY_UNIT,%MFG_DELAY_VALUE *END Create a Drilling Dwell Delay operation. In the dialog box showing the available options, set the Dwell mode to Revolutions and enter a numerical dwell value of `5'. In this case the statement generated in the resulting APT source will be: DELAY/REV,5.000 If the operation was created with the Dwell mode set to Time Units and a dwell value of `5', the statement generated in the resulting APT source would be: DELAY/5.000


PP Word Syntaxes

1.

NC Instructions You can define for a given machine tool (i.e. post-processor) sequences of PP word syntaxes associated to particular NC instructions. NC instructions are either axial machining operations or auxiliary commands. A syntax comprises a major word and one or more syntax elements such as minor words, numerical values and standard parameters. A set of standard parameters is associated to each NC instruction. Parameters may be combined in arithmetical expressions. A syntax that includes parameters is a parameterized syntax (see example below): *START_NC_INSTRUCTION NC_TOOL_CHANGE *START_SEQUENCE TOOLNO/%MFG_TOOL_NUMBER,%MFG_NOMINAL_DIAM TPRINT/%MFG_TOOL_NAME LOADTL/%MFG_TOOL_NUMBER *END *END Note that the `%' character indicates a parameter.

2.

3. 4.

You can define one or more syntax sequences for each NC instruction. The following example shows how the NC instruction NC_DRILLING_DWELL_DELAY could be used to generate a specific NC data output. Make sure that the PP word table is referenced by the machine used in the Part Operation and the syntax associated with NC_DRILLING_DWELL_DELAY instruction is already created as follows: *START_NC_INSTRUCTION NC_TOOL_CHANGE *START_SEQUENCE CYCLE / DRILL, %MFG_TOTAL_DEPTH, %MFG_FEED_MACH_VALUE, &MFG_FEED_UNIT, %MFG_CLEAR_TIP, DWELL, %MFG_DWELL_REVOL *END *END Create a Drilling Dwell Delay operation. In the dialog box showing the available options, set: hole depth to 25.0 feedrate to 500.0 approach clearance to 5.0 Dwell mode to Revolutions and enter a numerical dwell value of `3'. In this case the NC data output is as follows: CYCLE/DRILL, 25.000000, 500.000000, MMPM, 5.000000, DWELL, 3 The PP word table is updated with your syntaxes when you save the file.


PP Tables and PP Word Syntaxes

PP Tables and PP Word Syntaxes PP Word Tables You can create and manage Post-Processor word tables with NC Manufacturing products. A sample PP word table is delivered with the product, and can be used as a basis for creating user-defined tables. A PP word table is stored in a unique text file with suffix pptable. A PP word table can be defined for a specific machine tool and used in NC applications. You can also define the general syntaxes of post-processor words. These syntaxes will be proposed when you want to create a PP instruction. A PP word table comprises: major words without parameters major words with a text major words with parameters minor words word syntaxes. You can define for a given machine tool: syntaxes associated to particular NC commands sequences of PP word syntaxes associated to particular NC instructions. The NC Manufacturing product will resolve the parameters of these syntaxes and syntax sequences and generate the corresponding statements in the APT output.

NC Commands You can define for a given machine tool (i.e. post-processor) PP word syntaxes associated to particular NC commands. An NC command is a machine function such as feedrate declaration (NC_FEEDRATE) or spindle activation (NC_SPINDLE_START). A syntax comprises a major word and one or more syntax elements such as minor words, numerical values, lists and parameters. A syntax that includes lists or parameters is a parameterized syntax (see example below): *START_NC_COMMAND NC_COMPENSATION LOADTL/%MFG_TL_NUMBER,%MFG_TOOL_COMP *END Note that the & character indicates a list and the % character indicates a parameter. A list has a finite number of values. You can define only one syntax for each NC command. For an example of how to define syntaxes in NC commands, please see PP Word Syntaxes in the Customizing section of this guide.

Specification Tree

Specification Tree Here is an example of a Process Product Resources (PPR) specification tree for NC Manufacturing products. Process List is a plan that gives all the activities and machining operations required to transform a part from a rough to a finished state. Part Operation defines the manufacturing resources and the reference data. Manufacturing Program is the list of all of the operations and tool changes performed. Pocketing.1 operation is complete and has been computed. Pocketing.3 operation is complete but has not been computed. Pocketing.2 operation has not been computed and does not have all of the necessary data (indicated by the exclamation mark). Product List gives all of the parts to machine as well as CATPart documents containing complementary geometry. Resources List gives all of the resources such as machine or tools that can be used in the program.

The part of a tool path that ends where the tool begins to cut the material The speed of linear advancement of the tool during its approach, before cutting.

C Climb milling

A cutting mode where the front of the tool (advancing in the machining direction) cuts into the material first.

Check element

Geometry that represents material that is not to be machined in an operation. It often represents a clamp that holds the part to machine in place.

Glossary


Conventional milling Cut depth

This type of machining uses a contour as guide. There are three types of contour driven machining: parallel contours where the tool sweeps out an area by following progressively distant (or closer) parallel offsets of a given guide contour. between contours where the tool sweeps between two guide contours along a tool path that is obtained by interpolating between the guide contours. The ends of each pass lie on two stop contours. spine contour where the tool sweeps across a contour in perpendicular planes. A cutting mode where the back of the tool (advancing in the machining direction) cuts into the material first. See Climb milling. The maximum depth of the cut effected by the tool at each pass.

F Feedrate Frontal wall

The speed of linear advancement of the tool into the material while cutting. An area of the part surface that forms an inclined wall that the advancing tool will climb or descend.

G Guide contour

A contour used to guide the tool during an operation. See Contour-driven machining.

I Imposed plane

Inner point

A plane that the tool must pass through. This option is useful for machining parts that have grooves or steps and when you want to make sure that these areas are cut. The point where the tool will start cutting in a roughing operation when the surface to machine has pockets.

L Lateral wall Limit line Lower plane

An area of the part surface that forms an inclined wall that the tool will advance along laterally instead of climbing or descending. A contour that is used to delimit the areas to machine in an operation. One of the two planes normal to the tool axis that confines the area to machine. The operation will only machine between this plane and the upper plane.


Glossary

M Machining area

An area defined on a part either: during an operation as part of the machining geometry , or before an operation, the operation being assigned to a machining area afterwards. A machining area can be: the whole part (for example, in roughing), a subset of the faces on the part, a subset of faces on the part with a limiting contour.

P Pencil operations

Plunge Pocket

P.P.R.

A pencil operation is one where the tool remains tangent in two places to the surface to be machined during the cycle. It is often used to remove crests along the intersection of two surfaces that were left behind by a previous operation. A movement where the tool plunges deeper into the material, advancing along the (negative) tool axis. An area on a part surface that represents an internal depression (in Z) relative to the surrounding part surfaces. An internal depression is one that does not extend to the outside edge of the part. Process Product Resources.

R Retract Rework area Reworking Roughing Rough stock

The part of a tool path that begins where the tool stops cutting the material. An area that cannot be machined with a given tool. An operation which touches up zones that are left completely unmachined by previous operations. An operation where a part is rough-machined by horizontal planes. The block of raw material to be machined to produce a part.

S Safety distance Scallop height Spindle speed Start point

A horizontal clearance distance that the tool moves over at the feedrate in order to disengage the tool from cutting between passes. The maximum allowable height of the crests of material left uncut after machining. The speed of the spinning tool around its axis. The point where the tool will start cutting in a roughing operation where the surface to cut is accessed from the outside of the part.


Glossary

Stepover distance Stop contours

Sweeping operations

Sweep roughing

The width of the overlap between two successive passes. The two contours connecting the ends of two guide contours in contour-driven machining (between contours option). The ends of each pass lie on the stop contours. Sweeping operations machine the whole part and are used for finishing and semi-finishing work. The tool paths are executed in vertical parallel planes. An operation where a part is rough-machined by vertical planes.

U Upper plane

One of the two planes normal to the tool axis that confines the area to machine. The operation will only machine between this plane and the lower plane.

Z ZLevel machining

An operation where the tool progressively follows the part surface at different constant Z values (heights).
