Explanation
Retraction plane (abs)
Reference point (abs)
Safety clearance (to be added to reference point, enter without sign)
Drilling depth (abs), see _AMODE
Drilling depth (inc), see _AMODE
Dwell time in seconds at drilling depth/safety clearance after retraction, see ENC
Direction of rotation for retraction
Direction of rotation after end of cycle
Tapping with spindle mounted encoder (G33)/tapping without spindle mounted encoder
(G63)
0 = With spindle mounted
encoder
20 = With spindle
mounted encoder
11 = Without spindle
mounted encoder
1 = Without spindle
mounted encoder
Thread size for "ISO metric" only (pitch is calculated internally during run time)
Range of values: 3 to 48 (for M3 to M48), alternative to PIT
Pitch as a value, for unit see _PITA)
Range of values: > 0, alternative to MPIT
Drilling axis:
0 = 3rd geometry axis
1 = 1st geometry axis
2 = 2nd geometry axis
≥ 3 = 3rd geometry axis
- Pitch from MPIT/PIT - without DT
- Pitch from MPIT/PIT - with DT after retraction to
safety clearance
- Pitch from MPIT/PIT - with DT at drilling depth
- Pitch from programmed feedrate - with DT at drilling
depth (feedrate = speed · pitch)
