When performing oblique plunge-cutting using a straight wheel, this parameter must be pro-
grammed. When an inclined wheel is used, the contents of the TPG8[ ] parameter (angle of
the inclined wheel) are taken into account in the cycle. The contents of WIN are then ig-
nored.
B_ART (machining type)
The B_ART parameter is used to define the machining type used to machine a technological
section. Possible values for B_ART lie in the range between 1 and 3 with the following mean-
ing:
1 = roughing
2 = finishing and fine-finishing
3 = roughing, finishing and fine-finishing
A_LU (air allowance)
The term 'air allowance' is used to denote the distance between the starting position in Z and
the stock allowance for roughing.
A_SR, A_SL, A_FSL (allowance)
For the various machining steps, different values can be defined for the allowance. These re-
fer to the nominal diameter.
A_SR
A_SL
A_FSL
F_SR, F_SL, F_FSL (feedrate)
Different feedrates can be specified for the individual machining steps. They are program-
med in [mm/min].

F_SL
F_FSL
TIME (sparking-out time)
After reaching the workpiece finished dimension, the tool dwells at the end position for a de-
fined time. This time is called 'sparking-out time'. It is programmed in [s].
MZ (measurement control)
The MZ parameter is used to specify whether a measurement control is used.
0 = No measurement control
1 = With measurement control
KS (direct-contact vibration pick-up)
The KS parameter is used to specify whether a caliper is used.
0 = without direct-contact vibration pick-up
1= with direct-contact vibration pick-up
F_KS (feedrate for air grinding)
With an air grinding feedrate, the path between the starting point and the point where the
wheel comes into contact with the workpiece (with the aid of the direct-contact vibration pick-
up) is traversed.
