SRZ, SLZ, FSLZ (infeed amount for roughing, finishing and fine-finishing)
When grinding by reciprocating, the wheel is fed in at the reversal points, depending on the
machining type (roughing, finishing or fine-finishing). The infeed amount is programmed us-
ing the parameters SRZ, SLZ and FSLZ.
ZU_ART (infeed)
When grinding by reciprocating, the wheel is fed in at the reversal points. The ZU_ART pa-
rameter is used to define whether an infeed by the infeed amount is to be performed only at
the left, at both or at the right reversal point.
BVU1 and BVU2 (holding time at the reversal point)
The dwell time at reversal point 1 or 2 can be defined using the following value:
>0 = Wait for exact stop fine and then wait for stopping time to elapse
The unit for the dwell time is given in workpiece speed after infeed.
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
N_FR (number of sparking-out strokes)
Once the finished dimension is reached when grinding by reciprocating, a number of addi-
tional reciprocation strokes are performed without further infeed of the wheel. These strokes
are called 'sparking-out strokes'. The number of the sparking-out strokes is defined in the
N_FR parameter.
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.
