U Start angle C axis Q419 (absolute): Starting angle in
the C axis at which the first measurement is to be
made. Input range -359.999 to 359.999
U End angle C axis Q420 (absolute): Ending angle in the
C axis at which the last measurement is to be made.
Input range -359.999 to 359.999
U Angle of incid. in C axis Q421: Angle of incidence
in the C axis at which the other rotary axes are to be
measured. Input range -359.999 to 359.999
U Number meas. points C axis Q422: Number of probe
measurements with which the TNC is to measure the
C axis. Input range 0 to 12. If input value = 0, the TNC
does not measure the respective axis.
U No. of measuring points (4/3) Q423: Specify
whether the TNC should measure the calibration
sphere in the plane with 4 or 3 probing points. 3
probing points increase the measuring speed:
4: Use 4 measuring points (standard setting)
3: Use 3 measuring points
U Preset (0/1/2/3) Q431: Specify whether the TNC is
to set the active preset (datum) automatically in the
center of the sphere:
0: Do not set the preset automatically in the center of
the sphere: Set the preset manually before the start
of the cycle
1: Set the preset automatically in the center of the
sphere before measurement: Pre-position the touch
probe manually over the calibration sphere before the
start of the cycle
2: Set the preset automatically in the center of the
sphere after measurement: Set the preset manually
before the start of the cycle
3: Set the preset in the center of the sphere before
and after measurement: Pre-position the touch probe
manually over the calibration sphere before the start
of the cycle
U Backlash, angle range Q432: Here you define the
angle value to be used as traverse for the
measurement of the rotary axis. The traversing angle
must be significantly larger than the actual backlash
of the rotary axes. If input value = 0, the TNC does not
measure the backlash. Input range: -3.0000 to
+3.0000
If you have activated "Preset" before the calibration (Q431
= 1/3), then move the touch probe by the safety clearance
(Q320 + SET_UP) to a position approximately above the
center of the calibration sphere before the start of the
cycle.
