Explanation
Feedrate for roughing/finishing
Infeed abscissa groove turning
Feedrate for insertion into relief cuts, roughing
Infeed ordinate groove turning
Retraction plane for internal machining (abs, always diameter)
Roughing infeed (see _AMODE UNITS)
X infeed (see _AMODE UNITS)
Z infeed (see _AMODE UNITS)
Finishing allowance X, (see _VARI TEN THOUSANDS)
Finishing allowance Z, (see _VARI TEN THOUSANDS)
Finishing allowance parallel to contour, (see _VARI TEN THOUSANDS)
Additional finishing allowance while finishing (see_AMODE THOUSANDS)
Definition of blank
1 = Cylinder with allowance
2 = Allowance at contour of finished part
3 = Contour of blank is given
Definition of blank X (see _AMODE HUNDRED THOUSANDS)
Definition of blank Z (see _AMODE MILLION)
Limit 1 X (abs, always diameter)
Limit 1 Z (abs)
Limit 2 X (see _AMODE TEN MILLION)
Limit 2 Z (see _AMODE HUNDRED MILLION)
Grooving limit 1 for grooving on front face (abs, always diameter)
Grooving limit 2 for grooving on front face (abs, always diameter)
Number of grooves
Distance between grooves
Longitudinal groove: parallel to Z axis
Transverse groove: parallel to X axis
Distance for interruption of infeed
0 = no interruption
0 > with interruption
Safety clearance for avoiding obstacles, incremental
D number for 2nd edge of tool; if not programmed ⇒ D+1
