Description
2.7 Probe, calibration body, calibration tool
Parameters of the tool probe
Setting data:
● For machine-related measurement/calibration:
– SD 54626 $SNS_MEA_TP_TRIG_PLUS_DIR_AX1
– SD 54625 $SNS_MEA_TP_TRIG_MINUS_DIR_AX1
– SD 54627 $SNS_MEA_TP_TRIG_MINUS_DIR_AX2
– SD 54628 $SNS_MEA_TP_TRIG_PLUS_DIR_AX2
● For workpiece-related measurement/calibration:
– SD 54641 $SNS_MEA_TPW_TRIG_PLUS_DIR_AX1
– SD 54640 $SNS_MEA_TPW_TRIG_MINUS_DIR_AX1
– SD 54642 $SNS_MEA_TPW_TRIG_MINUS_DIR_AX2
– SD 54643 $SNS_MEA_TPW_TRIG_PLUS_DIR_AX2
The default setting has data fields for 6 probes.
In addition to turning tools, drills and mills can also be measured.
Calibration, gauging block
A probe must be calibrated before it can be used. To do this, when using measuring cycles in
the AUTOMATIC mode, before calibration, the approximate values must be entered into the
setting data listed above for the corresponding probe. Only then can the approximate position
of the probe be identified in the measuring cycle.
Calibration involves precisely determining the trigger points (switching points) of the tool probe,
and entering them in the corresponding parameters.
Calibration tool (type 585 or type 725) or turning tool (type 5xy) can be used for calibration.
The precise dimensions of the tool are known.
Measurement version Calibrate probe (CYCLE982) (Page 255) is provided for calibration.
