CHAPTER

1

1 Expert cut This chapter's purpose is to help the user in his first steps with Lantek Expert programming system. This chapter includes:

1.1 FOLDER/JOBS The Folders can be created to manage various jobs. To work with Folders, you have to enable the Job explorer parameter. This Job explorer option provides the list of folders and Jobs that are created. One can create a folder inside another folder. Any new jobs created can be organized in folders in a tree structure shown on the left side of the panel in the CAM window.

1.2 CREATING A FOLDER/JOB 1. Execute the main program: Start - Programs - Lantek - Lantek Expert CAM 2. Once inside the main program of Expert, Select the option Job explorer: CAM-View-Display-Job Explorer. The user can create a new Folder/Job by clicking the right button of the mouse on the Database or any existing folder.

11

Expert

Cut Module

Figure 1: Job explorer dialog box

Folder created by clicking on the database will create a Primary folder. Folder created by clicking on an existing folder will create a subfolder inside the selected folder.

1.3 JOB DETAILS In the Job explorer, the created jobs have two identifiers: name and references. Whenever a job is created, an automatic reference is generated which will be unique in the database, and the user will have to give a name for it. The same job name cannot be repeated again with the same name in the same folder. The user can view the listed jobs of the created parts by right clicking on the Job>Open, which can be viewed on the right hand side of the panel. A new job can be assigned with a new name, reference, user data and order information. The user can open, export, cut and paste, delete and view or modify the property parameters of a new job.

4.6 NESTING FOR MULTITORCH


The user can configure the number of torches for the machine. The system supports to use up to 20 torches at the same time. Each torch may have different capabilities for cut, mark or for machine chamfers or notches, and the user can choose the capabilities of each torch. In order to configure a machine with multitorch, do the following: 1. Select the option Multitorch data- CAM – Manage - ComponentsMachines - Cutting Machine – Configure - Machine Tab - Multitorch data. 2. The system displays a dialog box.

3. Enter the data as follows and click on OK. •

Torches on axis Y: Depending on each machine, the torches can be placed on X axis (by default), or in Y axis. It is important to specify to system which kind of torches placement the machine uses.

•

Control torch: It establishes the reference torch. The CNC program is built for this torch and the other torches follow the movements of this torch. The options depend on the previous parameter. If the torches are on axis X, the possible movements are Right and Left. If the torches are on axis Y, the possible movements are Up and Down.

•

Minimal and Maximal distance between torches: This is the minimum and maximum distance allowed between the two torches.

•

View configuration in "Do all" : The multitorch configuration is shown each time when the user clicks "Do All" option in the Nesting module, which makes the nesting and machining process automatically for all the parts depending on the 46

This option is available only if multiple torches are configured in the machine

The Multitorch data dialog box shows the list of torches along with the capabilities and distances of each one Automatic distances: If enabled, the system will calculate the optimal distances between torches for the related nesting, Disabled, the user can manually enter the distances. For making it easier, and if the distance is fixed between torches, the Equal distances button can be pressed after input one value, resulting on automatically filled the rest of values. Work with fixed number of torches: With this option, the system will make the nesting with all the active torches at the same time. 47

5 Remnants 5.1 CREATE REMNANTS This option generates remnants automatically depending on the configuration made on the machine’s sheet remnant.

5.2 DRAW THE EDGE


This option allows you to draw a polyline using dots and arcs for limiting the remnant. In order for the remnant to be valid, the polyline must start and finish in the external area of the sheet. It must also meet some requirements such as minimum area and not trespassing with the cutting margins of the parts.

6 Machining With this option ( ) the system will machine the nested parts automatically depending on the options configured in the automatic machining section of the cutting / punching machine configuration.

6.1 MANUAL MACHINING Machining allows you to cut the various parts manually.

6.2 MANUAL CONTOUR MACHINING Select manual contour to cut the selected elements of the contour.

6.2.1 All holes Select this to machine all the holes of parts on a sheet as follows: 1. Select ‘All Holes’ and then click OK. The system displays Machining initialization dialog box 2. You can set various initialization parameters and then click Finish. The system machines all the holes of the parts.

6.2.2 Parts Select ‘Parts’ to machine the entire part.

Glossary C

CAD: Cartesian Coordinates:

CAD is Computer-aided Design where computer technology is used to design the objects. It is a rectangular coordinate system that identifies each point on a plane with a pair of numerical co-ordinates, which are at a directed distance from the point to the axis.

Chamfer:

It is a beveled edge connecting two surfaces.

Compensation:

It is the compensation for the cutter radius.

CNC:

CNC is Computer Numerical Controlled machine tools used in the design process.

Construction Lines:

Coordinates:

It is used as an auxiliary tool in the complex construction of geometries for the part. These lines do not have definite ends. It is a set of numbers used to specify the location of a point on a line or a surface or a dimensional space.

D Default Thickness: Default Sheet Thickness for parts being exported to Lantek Expert System.

E Edge Length:

Value of linear distance is used to approximation cutting edges. 57

F Fillets:

It is a concave junction when two surfaces meet, forming a rounded corner.

J Jobs:

Platform for parts and nestings

L Laser eye:

The Laser eye is a device in some laser machines which is used to detect and avoid collisions with the head.

M Machining:

Macros: Modified Rectangles: Multitorch:

It is a part of manufacturing process. Machining is a collection of working process where machine tools with a sharp cutting tool are used to mechanically cut the material. It consists of machining instructions. They are rectangles with special corners. They are many torches used for machining a part.

N Nesting:

The sheet parts are distributed on the sheets or remnants.

O Obrounds: One-touch Figures:

A geometrical shape consisting of two semicircles connected by parallel lines tangent to their end points. These are different types of notches that can be introduced in the geometry of a part.

Cut Module

P Polar Coordinates:

It is a two dimensional coordinate system where each point on a plane is determined by a distance from a fixed point and an angle from a fixed direction.

R Remnants:

An unused/remaining part of the sheet.

O Open contour:

A curve without ends.

S Sub-job:

The jobs are divided into sub-jobs based on material, thickness, machine, and so on.

W Work chutes:

It consists of different types of part evacuation.

T Torch:
