The tool is moved at rapid traverse to the programmed position,
allowing for the retraction plane and safety clearance. It is then
inserted into the workpiece at the feedrate programmed under F until
it reaches the programmed depth (Z1). The spindle stops are a
specific position there. "Lift off contour" or "Do not lift off contour" can
be programmed on expiry of the dwell time.
With retraction, withdrawal distance D and the tool orientation angle α
can either be defined via machine data or in the parameter screen. If
both parameters are pre-assigned via machine data, they do not
appear in the parameter screen.
Please refer to the machine manufacturer's instructions.
Press the "Drilling" and "Boring" softkeys.
