Touch Probe Cycles: Special Functions | CALIBRATE TS (Cycle 460, DIN/ISO: G460, software option 17)
Q407 Radius of calib. sphere? Enter the exact
radius of the calibration sphere used. Input range
0.0001 to 99.9999
Q320 Set-up clearance? (incremental): Additional
distance between measuring point and ball tip.
Q320 is added to SET_UP (touch probe table), and
is only effective when the preset is probed in the
touch probe axis. Input range 0 to 99999.9999
Q301 Move to clearance height (0/1)?: Definition
of how the touch probe is to move between the
measuring points:
0: Move at measuring height between measuring
points
1: Move at clearance height between measuring
points
Q423 Number of probes? (absolute): Number of
measuring points on the diameter. Input range 0 to
8
Q380 Ref. angle in ref. axis? (absolute): Enter
the reference angle (basic rotation) for measuring
the measuring points in the active workpiece
coordinate system. Defining a reference angle can
considerably enlarge the measuring range of an
axis. Input range 0 to 360.0000
Q433 Calibrate length (0/1)?: Define whether the
TNC is to calibrate the touch probe length after
radius calibration, as well:
0: Do not calibrate touch probe length
1: Calibrate touch probe length
Q434 Preset for length? (absolute): Coordinate of
the calibration sphere center. The definition is only
required if length calibration is to be carried out.
Input range -99999.9999 to 99999.9999
Q455 No. of points for 3-D calibrtn.? Enter the
number of probing points for 3-D calibration. A
value of about 15 probing points is useful. If 0
is entered here, no 3-D calibration is performed.
During 3-D calibration, the deflecting behavior
of the touch probe is determined under various
angles, and the values are stored in a table. 3D-
ToolComp is required for 3-D calibration. Input
range 1 to 30
