The center offset is then automatically compensated during all probing
processes (see the User's Manual):

With MP6160, select whether the spindle should be oriented in a 180°
rotation directly through the NC or through the PLC.
If the spindle is oriented by the NC, you must reset M4012 (See "Oriented
Spindle Stop" on page 6 – 201).
For spindle orientation by the PLC you must enter the number of the
M function in MP6160. The respective position is transferred as in the
"oriented spindle stop" cycle.
In the MANUAL and ELECTRONIC HANDWHEEL modes, a triggering touch
probe is rotated by pressing a soft key. A measuring touch probe is
automatically rotated during calibration:

With MP6321, select if the rotation should be automatic. M4017 is set for
every spindle orientation.
Special case: tilting axes
The actual position of the spindle position encoder can vary with tilted axes. It
depends on the machine's mechanical design. Since the TNC uses the actual
position of the spindle as its reference when compensating the eccentricity, it
would be necessary to recalibrate the touch probe for each new tilt in position:

In D760, enter the current offset with respect to the initial position.
7 7 7 7
Calibrate the touch probe in the initial position.
The TNC compensates the entered offset when compensating the
eccentricity. In the initial position, D760 must equal 0.
