Manual retraction

After the interruption in machining due to power loss or a RESET at the machine control
panel, you have the possibility to retract the tool in the JOG mode in the tool direction without
damaging the tool or the 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.
Both the Z axis as well as the spindle can be used for retraction for the thread.
The "Retraction" function must be set up by the machine manufacturer.
