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 X starting position is calculated as the setpoint diameter + stock allowance + air
allowance. Optionally, the surface can then be sparked using an acoustic emission sensor.
The technological sequence programmed in the selected mode is executed when grinding by
reciprocating. The infeed is performed both at the reversal points of the reciprocating motion
either on the right, on the left or at both points. The motion behavior at these reversal points
can be programmed.
In the reversal points, a programmed stopping time becomes effective in revolutions of the
calculated workpiece after the infeed takes place.
A sparking-out time with subsequent retraction to the starting position is performed at the
end position for machining.
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
