Compensating workpiece misalignment

The TNC electronically compensates workpiece
misalignment by computing a "basic rotation".
You set the rotation angle to the desired angle with
respect to the reference axis in the working plane
(see page 1-13).

Press the PROBING ROT soft key.

ROTATION ANGLE =

Enter the nominal value of the rotation angle.

Move the ball tip

Displaying calibration values

The effective length and radius, and the center
misalignment of the 3D touch probe are stored in
the TNC for use when the touch probe is needed
again. You can display the values on the screen
with the soft keys CAL L and CAL R.
