Explanation
Reference point in Z (abs)
Reference point in X (abs), in diameter
Intermediate point 1 in Z (abs/inc), see _AMODE (UNITS)
Intermediate point 1 in X (abs/inc), see _AMODE (TENS) or
Thread inclination 1 (-90° to 90°)
abs is always diameter, inc is always radius
Intermediate point 2 in Z, (abs/inc), see _AMODE (HUNDREDS)
Intermediate point 2 in X (abs/inc), see _AMODE (THOUSANDS) or
Thread inclination 2 (-90° to 90°)
abs is always diameter, inc is always radius
End point in Z, (abs/inc), see _AMODE (TEN THOUSANDS)
End point in X, (abs/inc), see _AMODE (HUNDRED THOUSANDS) or
Thread inclination 3 (-90° to 90°)
abs is always diameter, inc is always radius
Thread approach (inc, to be entered without sign)
Thread run-out (inc, to be entered without sign)
Thread depth (inc, to be entered without sign)
Finishing allowance in X and Z
Infeed slope as a distance or an angle, see _AMODE (MILLION)
The infeed slope is applied according to the setting of parameter _VARI (HUNDREDS).
Definition of _VARI_HUNDERTER = 0 - Compatibility mode:
> 0 = Side infeed on one side
0 = Infeed vertical in the thread
< 0 = Side infeed with alternating sides
Definition for _VARI_HUNDERTER<>0:
> 0 = Infeed on the positive side
0 = Center infeed
< 0 = Infeed on the negative side
Starting angle offset for the 1st thread
Number of roughing cuts, see _VARI (TEN THOUSANDS)
