Engine and turbine components
Example program code
The key aspects of engine and turbine components production are illustrated below on the basis
of the start program and a finishing program.
It is recommended that all of the technology parameters such as feedrate, speed, HSC settings
(CYCLE832), vector smoothing (ORISON), and special M codes be defined in the main program.
All feedrate values are defined here as R parameters. This allows greater flexibility when
optimizing the feedrate values for the machine operator.
The subprogram should only contain geometry information. For testing the program, it is
recommended that the subprograms be structured in such a way that they can be processed
individually. To this end, jump marks should be set in the main program for jumping to a specific
subprogram. Experience has shown that this is faster and more effective than a block search.
