Explanation
Reference point (abs)
Reference point (abs, always diameter)
End point in conjunction with _AMODE (UNITS)
End point in conjunction with _AMODE (TENS)
Thread run-in in conjunction with _AMODE (HUNDREDS) or
Thread run-in = thread run-out in conjunction with _AMODE (HUNDREDS)
Thread run-out
Thread depth
Finishing allowance in X and Z
Infeed slope as a distance or an angle, in conjunction with _AMODE (THOUSANDS)
> 0 = Infeed on the positive side
< 0 = Infeed on the negative side
0 = Center infeed
Starting angle offset (only effective with "single start")
Number of roughing cuts, in combination with _VARI (TEN THOUSANDS)
Number of non-cuts
Pitch as a value, in conjunction with _PITA
Machining type
UNITS: Technology
1 = External thread with linear infeed
2 = Internal thread with linear infeed
3 = External thread with degressive infeed, cross-section of cut remains constant
4 = Internal thread with degressive infeed, cross-section of cut remains constant
TENS: Reserved
HUNDREDS: Infeed type
1 = Infeed on one side
2 = Infeed alternate sides
THOUSANDS: Reserved
