Function
The shoulder plunge-cutting cycle can be used to machine a workpiece shoulder by plunge-
cutting in the Z direction. The direction depends on the cutting edge used (refer to "Tools and
Tool Radius Compensation")
Shoulder plunge-cutting involves only roughing and finishing.
An acoustic emission sensor can be used to bridge the distance between the starting point
and the actual workpiece surface within an optimum time by sparking.
Parallel to the grinding process, a short-travel reciprocation can be activated in the X
direction via reciprocation commands.
