Example for shoulder plunge-cutting
Complete machining of a shoulder to a width of 50 mm with reciprocation using a direct-
contact vibration pick-up.

Sequence of operations
The machining start position is first approached in X, then in Z, corresponding to the initial
position of the grinding wheel in Z, if the current X value is less than the X allowance.
The Z starting position is calculated as the shoulder dimension in Z + roughing allowance +
air allowance.
The surface can be sparked using a direct-contact vibration pick-up. Optionally, the recipro-
cating motion is activated in X, and the subsequent roughing operation is performed by
Grinding
