Sequence of operations
The machining start position is first approached in X, then in Z, corresponding to the initial
position of the grinding wheel in X, if the current X value is less than the X allowance.
The starting position is calculated as the setpoint diameter + stock allowance + air
allowance. Optionally, the surface can be then sparked using an acoustic emission sensor
and adding the Z direction oscillating motion.
Machining by grinding is assigned the parameter B_ART, the value programmed taking into
account the stock allowance, and the appropriate feedrate.
The reciprocating motion and the subsequent retraction to the starting position are stopped
at the end position for machining after expiry of a sparking-out time
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)
For taking into account a seat compensatioin, the N_SITZ parameter is used to enter the
number of the workpiece seat to be machined.
X_SOLL (setpoint diameter)
The setpoint diameter corresponds to the finished dimension in the X direction.
Z_ST (starting position in Z)
Z_ST is used to define the starting position of the grinding motion in the Z direction.
