Cycle974 Measuring Cycle Parameters - Siemens SINUMERIK 840D sl Programming Manual

The groove width from the difference of the position values of the groove wall must be determined precisely (precision dial
gauge).
For calibration in the groove, it is assumed that the tool length of the probe of the calibrated axis = 0.
The positions values for the groove base must also be determined precisely on the machine (no drawing dimensions).
Measuring axis S_MA=3 for calibration on a surface and on a turning machine with real 3rd axis of the plane (for G18 Y).
6)
Adapt tool length when calibrating length in the groove, or for lengths at the surface.
7)
Workpiece probe in lathes can be defined using 2 lengths (X Z).
Turning probe, type 580
cutting-edge position 7: For length calibration, optionally, the Z length is corrected.
Turning probe, type 580
cutting edge position 8: For length calibration, optionally, the X length is corrected
The tool length is not adapted for the measurement version, radius at groove or radius at the surface.
Only the corresponding trigger points are saved.
