Driving gear and turbine components

5.2

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.
