data.
Enter the diameter of the ring gauge
Enter the start angle
Enter the number of touch points
Start the probing procedure: Press the machine
START button. The 3-D touch probe probes all
required touch points in an automatic probing
routine and calculates the effective ball-tip radius.
If probing from opposite orientations is possible,
the TNC calculates the center offset
Checking the results
Press the
OK soft key for the values to take effect
Press the END soft key to terminate the calibrating
function. The TNC logs the calibration process in

prepared by the machine manufacturer. Refer to your
machine manual.
