Calibration using a calibration ring
Proceed as follows for manual calibration using a calibration ring:
In the Manual operation mode, position the ball
tip inside the bore of the ring gauge
Select the calibration function: Press the CAL. R
soft key
The control displays the current calibration data.
Enter the diameter of the ring gauge
Enter the start angle
Enter the number of touch points
Probe: Press the NC Start key
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
control calculates the center offset.
Check results
Press the OK soft key for the values to take
effect
Press the END soft key to terminate the
calibrating function.
The control logs the calibration process in the
TCHPRMAN.html file.
Refer to your machine manual.
In order to be able to determine ball-tip center
misalignment, the control needs to be specially
prepared by the machine manufacturer.
