Generating an NC Output File This task explains how to interactively generate NC code from the program you have just created. 1. Save your program with File/Save as in the directory of your choice (here we have a directory called models) and call your program MySurfaceMachining. Press Save. 2. Select Manufacturing Program.1 in the specifications tree and select Generate NC Code interactively in the contextual menu.

Select the Generate documentation icon . The process documentation dialog box is displayed. 2. Select the SurfaceMachinist4.CATScript file from the samples directory. Leave "Process" as the process name. Choose the directory where you want to store your new file (we have chosen MyFiles, but this is not obligatory). Leave "Process" in the Base field. 3. Press Document now. Your NC document has been created. Press Done to close the dialog box.

In this tutorial you are going to learn how to: define areas (including a rework area) on the part below, define tools to use on the areas, use a safety plane, change a tool axis, create an APT file and a workshop document. Entering the workbench Defining the areas to machine Defining the tools to use Sweep roughing the part Sweeping the top surface Sweeping the side areas ZLevel on vertical walls Reworking between contours Generating an output file Generating workshop documentation Area-oriented machining http://dsfr2e/itprm/doc/CXR7doc/doc/online/smgug/smguggs15.htm [5/17/2001 3:07:36 PM] Entering the Workbench This task shows you how to open a part and enter the Surface Machining workbench. 1. Open the Gets2.CATPart in the samples directory. 2. Select NC Manufacturing > Surface Machining from the Start menu. The Surface Machining workbench is displayed. The part is displayed in the viewer along with the manufacturing specifications. 3. Press MB2 and MB3 at the same time and turn the part round so that it looks like this. 4. Double click Part Operation.1 in the tree. In the dialog box that is displayed, click the design part icon and click the part in the viewer. The double click anywhere in the viewer and press OK. This step is necessary for the visualization and analysis part of the process.

You are going to define: the whole part as a machining area for rough machining purposes four other areas for use with different cycle types and a rework area. 1. Click on the Machining Area icon . 2. Place your mouse cursor over the red, sensitive area in the dialog box and press MB3. 3. Choose Body(ies) in the contextual menu. 4. Click the part in the view. The whole part is selected. Double click anywhere in the viewer to redisplay the dialog box.

Replace the text in the name box by Whole. Click OK. You have just created your first machining area. 6. Now create an area on the top of the part. Select the Machining area icon and click (MB1 this time) on the red, sensitive area in the dialog box. Now select the areas that you see selected in the picture below. Click on OK in the face selection toolbar. Call this area Top. 7. Now do the same for the left side of the part with these faces: Defining the areas to machine http://dsfr2e/itprm/doc/CXR7doc/doc/online/smgug/smguggs17.htm (2 of 6) [5/17/2001 3:07:43 PM] Call this area Left. 8. Define a third area with these faces and call it Right.
