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 = 3. Geometry axis
1 = 1. Geometry axis
2 = 2. Geometry axis
≥ 3 = 3. Geometry axis
Pitch unit (evaluation of PIT and MPIT)
0 = Pitch in mm
1 = Pitch in mm
2 = Pitch in TPI
3 = Pitch in inches
4 = MODULE
- 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)
- evaluation of MPIT/PIT
- evaluation of PIT
- evaluation of PIT (threads per inch)
