5.6 Simple stock removal of workpiece

The retraction function is especially useful when the coordinate system is swiveled, i.e. the
infeed axis is not in the vertical position.
Note
Tapping
In the case of tapping, the form fit between the tap and the workpiece is taken into account
and the spindle moved according to the thread.
The Z axis as well as the spindle can be used for retraction at the thread.
The "Retraction" function must be set up by the machine manufacturer.
