Calibration using a calibration sphere
Proceed as follows for manual calibration using a calibration sphere:
In the
Manual operation
mode, position the ball
tip above the center of the calibration sphere
Select the calibration function: Press the
CAL. R
soft key
Enter the outside diameter of the ball
Enter the safety clearance
Enter the start angle
Enter the number of touch points
Select Length measurement, if applicable
If necessary, input the reference for the length
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 TNC
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 TNC logs the calibration process in
TCHPRMAN.html.
In order to be able to determine the ball-tip center
misalignment, the TNC needs to be specially
prepared by the machine manufacturer.
Refer to your machine manual.
