3.7.2 Drilling and reaming
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 depth Z1.
Drilling: If Z1 has been reached and the dwell time expired, the drill is
retracted at rapid traverse either to the retraction plane or the safety
clearance depending on the setting in parameter "Retraction position
pattern". You will find parameter "Retraction position pattern" in the
program header or under "Settings" in the "Miscellaneous" menu.
Reaming: If Z1 has been reached and the dwell time expired, the
reamer is retracted at the programmed retraction feedrate to the
safety clearance.
