N_FR (number of sparking-out strokes)
Once the finished dimension is reached when grinding by reciprocating, a number of
additional 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 (acoustic emission sensor)
The KS parameter is used to specify whether an acoustic emission sensoris used.
0 = without acoustic emission sensor
1= with acoustic emission sensor
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 acoustic emission sensor) is
traversed.
UWERK
Use the UWERK parameter to specify the peripheral speed of the workpiece in m/min.
