Determining dimensions of calibration

Function
If no special calibration tool is available, a turning tool with cutting edge position SL=3 can be
used instead for calibration of two sides of the probe (_TP[i,0], _TP[i,2]).
With the following procedure it is possible to determine the dimensions as the calibration
tool.
Example: X axis, probe PRNUM=1 (_TP[0,2])
1. Approximate probe data in the data block GUD6: Parameters _TP[0,0]..._TP[0,3]
2. Measure the turning tool at the presetting location.
3. Enter all tool data in the tool offset (incl. e.g.: L1 = 60.000) and use the tool in the
4. Machine a test part (turn to X dimension), e.g.:
5. Adapting tool correction (L1 = 59.950).
6. Finish-turn the test part again, e.g.:
7. Calibrate tool probe in X axis
8. Measure tool (see section "Measure turning tool (machine-related)")
Another tool can then be measured and used as the calibration tool. Calibrate the probe; the
subsequent tool measurement must result in the same tool length.
