Function
The oscillating plunge cutting cycle is called for the purpose of machining a slot or surface
that is smaller than the wheel width. It can also be used for grinding front faces. The surface
concerned is ground using the oscillation method.
Infeed takes place at the reversal points. Intermediate dressing, interruption and use of the
handwheel are all supported.
The keys will only ever respond at the end point.
At the end, the tool retracts or grinding continues with a different technology.
Infeed is possible in the Y or Z directions and the Z value can be either negative or positive.
