Procedure
142
1. Load the workpiece probe into the spindle.
2. Enter the diameter and length approximately in the tool data.
3. Select the "JOG" mode in the "Machine" operating area.
4. Move the workpiece probe approximately over the center of the sphere.
5. Press the "Meas. workp." and "Calibrate probe" softkeys.
The window "Calibration: Probe" is opened.
6. Press the "Comp. to sphere" softkey.
The "Calibration: Probe on sphere" window opens.
7. In the "Calib. in infeed axis" selection box, choose "yes" if you want to
calibrate the probe in the plane and infeed axis.
- OR -
Choose "no" if you want to calibrate the probe on a reference surface.
8. If you choose "yes", enter the upper edge of the calibration sphere in "ZS"
if you want to calibrate the infeed axis.
The length of the workpiece probe is determined.
9. In the "Adjust tool length" selection box, choose "no" to save the deter‐
mined length difference in the calibration data set.
- OR -
Choose "yes" to calculate the length difference into the probe tool data.
Note
Please observe the information provided by the machine manufacturer.
10. Enter the sphere diameter in "Ø" and the probing angle in "α0".
11. Press the <CYCLE START> key.
Calibration starts.
All reference data are determined in three passes round the reference
