Explanation of the parameters
X_SOLL (maximum workpiece diameter)
The X_SOLL parameter serves to calculate the workpiece speed.
X_AB, Z_AB_L, Z_AB_R (dressing amount in X and Z)
The dressing amount is the cutting depth by which the wheel is reduced in X or Z when
dressing.
When using an inclined wheel, the dressing amount in Z is calculated using the wheel angle
and the X dressing amount.
FFW (retraction travel)
The FFW parameter specifies the retraction travel in both axes X and Z.
Z_LPOS (longitudinal position)
Selection of longitudinal positioning
0 = no longitudinal positioning
-1 = shoulder left
Z_SCH (shoulder dimension in Z)
The Z_SCH parameter is used to specify the width of the shoulder.
ZSTW (probe infeed travel)
The ZSTW parameter is used to program the incremental infeed amount of the probe in the
Z direction.
F_Z_MESS (measuring feedrate)
Acquisition of the measuring feedrate for the longitudinal position
N_ABR (number of dressing strokes)
The N_ABR parameter specifies how many strokes are required for the dressing of the
wheel.
