Precondition
For a G-code program, at least one CYCLE62 is required before CYCLE952.
If CYCLE62 is only present once, then this involves the finished part contour.
If CYCLE62 is present twice, then the first call is the unmachined part contour and the
second call is the finished-part contour (also see Chapter "Programming").
Set machining area limits
If, for example, you want to machine a certain area of the contour with a different tool, you
can set machining area limits so that machining only takes place in the area of the contour
you have selected.
Feedrate interruption
To prevent the occurrence of excessively long chips during machining, you can program a
feedrate interruption.
