Parameters
T, D, F, S, V See Sec. "Programming the tool, offset value and spindle speed".
Shank The drill is inserted into the workpiece until the drill shank reaches the value
programmed for Z1. The insertion angle entered in the tool list is applied.
Tip The drill is inserted into the workpiece until the drill tip reaches the value
programmed for Z1 (does not apply in reaming).
Z1 Insertion depth for drill tip or drill shank.
Z0 Height of workpiece; Z0 is specified in the position pattern ("Positioning" softkey).
DT Dwell time for relief cut.
FB Retraction feedrate (for reaming only)
3-232
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.
Press the "Drilling" and "Drilling reaming" softkeys.
