Function
The plunge-cut cycle is called for the machining of a cylindrical seat if the wheel width is
greater than or equal to the width of the seat to be machined. Either straight or inclined
wheels are used.
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 Z
direction via reciprocation commands.
The workpieces can be checked for their finished dimensions and the individual feedrates
can be switched in the various technological sections by means of a measurement control
(caliper) that is used during actual machining.
