Generate NC Code

task target This task shows you how to generate NC code from the program. An APT source file will be generated in this example.

Before doing this task, double-click the Part Operation entity in the tree and, in the dialog box that appears, click the Machine icon to access the Machine Editor dialog box. Make sure that you have selected a Horizontal lathe machine and that the desired NC data format is set to Axis (X, Y, Z).
scenario 1. Use the right mouse key on the Manufacturing Program.1 entity in the tree to select Generate NC Code Interactively. The Generate NC Output Interactively dialog box appears.

2. Select APT as the desired NC data type.
  3. Click the Output File button to select the folder where you want the file to be saved and specify the name of the file.
4. Click Execute to generate the APT source file.
An extract from a typical APT source file is given below.
