position (only
Drill hole at programmed position
for G code)
Position pattern
•
Position with MCALL
Z0 (only for G Reference point Z
code)
DIR Direction of rotation
•
(only for G
•
code)
Z1 Drilling depth (abs) or drilling depth in relation to Z0 (inc)
Dwell time at final drilling depth in seconds
DT •
Dwell time at final drilling depth in revolutions
•
SPOS Spindle stop position
Do not lift off contour
Lift mode •
The cutting edge is not fully retracted, but traverses back to the retraction plane.
Lift off contour
•
The cutting edge retracts from the edge of the hole and then retracts to the safety
clearance from the reference point and then positions at the retraction plane and
hole center point.
DX Retraction distance in the X direction (incremental) - (for lift-off only, standard)
