Sequence of operations
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 diameter + roughing allowance + air allowance
Z axis: Shoulder dimension in Z + (roughing allowance + air allowance)*tan(angle)
Note: If no angle is programmed 45° are used.
A 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, there is a compensation capability with the aid of the
variable _GC_KORR. This parameter specifies whether additional compensation should be
computed for the measurement control.
● _GC_KORR = 0: Nominal/actual deviation is taken into account for the wheel
● _GC_KORR = 1 - Nominal/actual deviation is taken into account for the active work offset
● _GC_KORR = 2 - Nothing is taken into account

N_SITZ (seat number)
The N_SITZ parameter is used to enter the number of the seat to be machined on the
workpiece.
X_SOLL (setpoint diameter)
The setpoint diameter corresponds to the finished dimension in the X direction.
