Manual retraction

After an interruption of a tapping operation (G33/G331/G332) or a general drilling operation
(tools 200 to 299) 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.
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.
