Manual Retraction - Siemens SINUMERIK 840D sl Universal Operating Manual

Manual retraction

In the following cases, the "Retract" function allows drilling tools to be retracted in the tool
direction in the JOG mode:
• After interrupting a thread tapping operation (G33/331/G332),
• After interrupting machining operations using drilling tools (tools 200 to 299) as a result of
power failure or a RESET at the machine control panel.
The tool and/or the workpiece remain undamaged.
Retraction 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.
Use the Z axis as well as the spindle when retracting from threads.
The machine OEM sets up the "Retract" function.
