Generate NC Data

task target This task shows you how to generate NC data in APT format from the program.

For more information about this procedure please refer to Program Output.
scenario 1. Use the right mouse key on the Manufacturing Program.1 entity in the tree to select Manufacturing Program.1 object > 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.

Please note that the Flank Contouring portion of this source contains information for cutter radius compensation. Output is the tool tip point (XT, YT, ZT), tool axis vector (IJK) and the drive surface normal (PQR).
