Sequence
The sequence for positioning to the machining position is: X axis first, then the Z axis, or vice
versa, depending on the park position of the grinding wheel in X.
The starting positions in X and Z are determined as follows:
●
X axis: Setpoint di roughing all air allowance
●
Z axis: Shoulder dimension in Z + roughing all air allowance
An acoustic emission sensor can be used for optional sparking, in which case the axes are
traversed simultaneously at an angle ("inclined axis"). Machining by grinding is performed
simultaneously in the X and Z axes up to finished dimension.
Once the sparking-out time has expired, both axes are retracted to the starting position.
When using a measurement control system, the _GC_KORR GUD variable can be used for
compensation. This parameter is taken into account internally via CYCLE433 (taking into
account the caliper compensation).
●
_GC_KORR = 0 - Nominal/actual deviation is taken into account in wheel wear
●
_GC_KORR = 1 - Setpoint-actual deviation is taken into account in work offset G507(X)
●
_GC_KORR = 2 - Nothing is taken into account
