Explanation N10 to N180, calibrate
The "tip" of the calibration tool T7 is positioned in measuring axis X from the starting position
at distance _FA=1 mm (dimension → with reference to the radius) before the probe. In axis Z,
the probe tip center is centered with respect to the probe.
The measuring process is initiated in the negative X direction (_MA=2, starting position) with
measuring velocity 150 mm/min (_VMS=0, _FA=1). The switching signal is expected by the
probe 1 (_PRNUM=1) within a distance of 2 · _FA=2 mm. Otherwise, an alarm will be
triggered.
Measurement is performed once (_NMSP=1). After successful measurement, the "tip" of T7
is _FA=1 mm in front of the probe in the X direction.
The calculated probe value is entered in _TP[0,2]. Calibration with the measuring process
has been completed in minus X.
Calibration is then performed in the other measuring directions/axes.
Explanation N200 to N300, measure
The probe is completely calibrated.
The "nose" of the turning tool T3 is positioned in measuring axis X from the starting position
at distance _FA=1 mm (dimension → with reference to the radius) in front of the probe. In
axis Z, the center of the cutting edge is centered with respect to the probe. If the cutting edge
radius =0, it is the tool nose.
The measuring process is initiated in the negative X direction (_MA=2, starting position) with
measuring velocity 150 mm/min (_VMS=0, _FA=1). The switching signal is expected by the
probe 1 (_PRNUM=1) within a distance of 2 · _FA = 2 mm. Otherwise, an alarm will be
triggered.
Measurement is performed once (_NMSP=1). After successful measurement, the "tip" of T3
is _FA=1 mm in front of the probe in the X direction.
The calculated length difference of L1 (tool type 5xy, _MA=2, _MVAR=1) is summated and
entered in D1 from T3 in the wear (_CHBIT[3]=1).
Measurement and wear offset are then performed in L2 in the minus Z direction.
