4 Measuring Cycle for Turning Machines
4.1.1 L972/L982 Calibrating the tool probe
Recommendation: Create a machine-specific calibrating subroutine using cycle L972/L982.
This program can be used when required either for each tool measure-
ment using the main program or via MDI (once a day).
Example: Machine-specific calibration subroutine (see Fig. 4.2 for more details)
On turning machines, the calibration tool is treated like tool type 3 and must be entered as
such in the TOA memory.
Values in the TOA memory D9:
The trigger points are always stored as radius values, even for a transverse axis.
Values in MDC: MDC 1020=50
MDC 1021=20
MDC 1022=70
MDC 1023=40
