Explanation
Amount/percentage for each additional infeed (degression amount/percentage), see
_AMODE
Dwell time at drilling depth, see _AMODE
Dwell time at start point (for chip removal only), see _AMODE
Percentage for the feedrate for the first infeed, see _AMODE
Machining type
UNITS: Chip breaking/removal
0 = Chip breaking
1 = Chip removal
Tool axis:
0 = 3rd geometry axis
1 = 1st geometry axis
2 = 2nd geometry axis
> 2 = 3rd geometry axis
Minimum infeed (only for degression percentage)
Retraction distance after each machining step (for chip breaking only)
> 0 = Variable retraction distance
0 = Standard value 1 mm
Dwell time at final drilling depth, see _AMODE
Limit distance (for chip removal only), see _AMODE
Geometrical mode (evaluation of programmed geometrical data)
UNITS: Reserved
TENS: Drilling depth with respect to tip/shank
0 = Tip
1 = Shank
Display mode
UNITS: Machining plane G17/G18/G19
0 = Compatibility, the plane effective before cycle call remains active
1 = G17 (only active in the cycle)
2 = G18 (only active in the cycle)
3 = G19 (only active in the cycle)
