Feedrate interruption
To prevent the occurrence of excessively long chips during machining, you can program a
feedrate interruption.
Input simple
For simple machining operations, you have the option to reduce the wide variety of parameters
to the most important parameters using the "Input" selection field. In this "Input simple" mode,
the hidden parameters are allocated a fixed value that cannot be adjusted.
If the workpiece programming requires it, you can display and change all of the parameters
using "Input complete".
Machining type
You can freely select the machining type (roughing, finishing or complete machining).
