4 Measuring Cycle for Turning Machines 08.96
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: Tool type 3
L1 geometry 10
L2 geometry 40
R radius 5
The trigger points are always stored as radius values, even for a transverse axis.
Values in MDC: MDC 1020=50 Minus direction of abscissa
MDC 1021=20 Plus direction of abscissa
MDC 1022=70 Minus direction of ordinate
MDC 1023=40 Plus direction of ordinate
