Manual Retraction - Siemens SINUMERIK 840D sl Operating Manual

The feedrate / rapid traverse override is active during traversing.
Procedure
5.5

Manual retraction

If a tapping operation (G33/G331/G332) – or machining with a drilling tool (tool 200 to 299) –
is interrupted as a result of a power failure or a RESET at the machine control panel, then
using the retraction function you can retract the tool in the tool direction in the JOG operating
mode. The tool and/or the workpiece remain undamaged.
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.
