Example program code
The key aspects of driving-gear and turbine-component production are illustrated below on the
basis of the start program and a finishing program.
Example start program The individual subprograms are called in the start program. All the tool and technology data is
stored in the subprogram. The start program controls how the NC programs generated with the
CAM system are called.
If you have a suitable post processor (e.g. from PostBuilder), both the main programs and
the subprograms can be generated automatically.
