TUTORIAL #1

















TUTORIAL #11 #11

OVERVIEW OF STEPS TAKEN TO CREATE THE FINAL PART:

OVERVIEW OF STEPS TAKEN TO CREATE THE FINAL PART: From Drawing to CAD Model:  The student should examine the drawing on the following page to understand what part is being created in the tutorial.  From the drawing we can decide how to go about creating the geometry in Mastercam.

Create the 2D CAD Model used to generate Toolpaths from:  The student will create a line in the Top Pane needed to create the toolpaths.  Two files will be created one for a cylindrical helix, another for a conical helix.  Geometry creation commands such as create line endpoint (horizontal and vertical), and the delete entities command will be used.

Create the necessary Toolpaths to machine the part:  The student will set up the stock size to be used and the appropriate tool settings.  A contour toolpath will be created to machine a cylindrical cylindrical helix using Axis Substitution.  Another contour toolpath will be created to machine a conical helix using Axis Substitution.

Backplot and Verify the file:  The Backplot will be used to simulate a step by step process of the tool’s movements.  The Verify will be used to watch a tool machine the part out of a solid model.

Post Process the file to generate the G-code:  The Student will then post process the file to obtain an NC file containing the necessary code for the machine.

















CREATE THE GEOMETRY OF THE CYLINDRICAL HELIX

TUTORIAL #11 #11

This tutorial covers Mastercam's 4 and 5-Axis toolpath functionality. To apply these toolpaths to a 5-Axis machine tool, a customized post processor for your machine is required. There are no default 5-Axis post processors included with Mastercam due to the variation in multi-axis machine configurations. Contact your Mastercam reseller to request post processor services such as multi-axis post development. Your post processor may require certain additional programming information not covered in this tutorial. For instance: You may be required to position your stock i n machine space rather than at Mastercam's origin. You may be required to use the Misc Values box. Your post may also prompt for tool gage lengths. The nature of the additional information required depends largely on your machine's configuration. Contact the developer of your post processor for details.

STEP 1: CREATE THE GEOMETRY OF THE CYLINDRICAL HELIX Cylindrical helix parameters: Diameter, D= 4". Number of spirals, n = 2. Helix length L= 8".

.

















TUTORIAL #11 #11


1.1 Create the Horizontal Line Create  Line.  

Endpoint. [Specify the first endpoint]: Select the Origin by moving the cursor at the center of the grid as shown in Figure: 1.1.1. 1.1.1. Figure: 1.1.1

From the Ribbon bar, enable the Horizontal icon.  [Specify the second endpoint]: endpoint]: Sketch the line to the right of the origin.  In the Ribbon Bar, enter the Length = 8.0 as shown. 



Select the Apply button to continue in the same command.

1.2 Create the Vertical Line NOTE: To calculate the length of the vertical line, use the computer calculator (start/run type "calc"). Enter pi* 2*4. Select Edit and copy (Ctrl + C).


















TUTORIAL #11 #11

1.3 Create Line Parallel Create  Line. Parallel.  [Select a line]: Select the horizontal line.  Select the upper endpoint of the vertical line as shown in Figure: 1.3.1. 1.3.1. 

Figure: 1.3.1



Select the OK button to exit the command.

The geometry should look as shown in Figure: 1.4.1. 1.4.1. Figure: 1.4.1



Select the OK button to exit the command.

1.5 Delete the two Horizontal Lines and the Vertical Line Click on the horizontal lines and on the vertical line and press Delete from the keyboard.  The geometry should look as shown in Figure: 1.5.1. 1.5.1. 

Figure: 1.5.1



















SELECT THE MACHINE AND SET UP THE STOCK

TUTORIAL #11 #11

STEP 2: SELECT THE MACHINE AND SET UP THE STOCK In Mastercam, you select a Machine Definition before creating any toolpaths. The Machine Definition is a model of your machine tool's capabilities and features and acts like a template for setting up machining jobs. The machine definition ties together three main components: the schematic model of your machine tool’s components, the control definition that models your control unit’s capabilities and the post processor that will generate the required machine code (G-code). For the purpose of this tutorial, we will be using the Mill 4 Axis VMC machine.

Step Preview:

















TUTORIAL #11 #11


Select the MILL 4 - AXIS VMC.MMD-7.  Select the Add button to add the machine into the Machine Definition Menu as shown in Figure: 2.1.1. 2.1.1.



2.3 Set the Tool Parameters in the Tool Settings 

Select the plus sign in front of Properties in the Toolpaths Manager to expand the Toolpaths Group Properties as shown.



Select the Tool Settings to set the tool parameters as shown in Figure: 2.3.1. 2.3.1. Figure: 2.3.1



















Change the parameters to match the Figure: 2.3.2. 2.3.2. Figure: 2.3.2

Program # is used to enter a number if your machine tool requires a number for a program name. Assign Tool Numbers Sequentially allows you to overwrite the tool number from the library with the next available tool number. (First operation tool number 1; Second operation tool number 2, etc.) Warn Of Duplicate Tool Numbers allows you to receive a warning if you enter two tools with the same number.

2.4 Set the Stock Shape and Size Select the Stock Setup tab to define the stock.  Set the Stock Shape to Cylindrical and the Axis to X.  Set the Diameter to 4.0 and the Length to 8.0 as shown in Figure: 2.4.1. 2.4.1.
