Touch Probe Cycles: Special Functions
16.6 CALIBRATE TS (Cycle 460, DIN/ISO: G460)
Exact calibration sphere radius Q407: Enter the
exact radius of the calibration sphere used. Input
range 0.0001 to 99.9999
Set-up clearance Q320 (incremental): Additional
distance between measuring point and ball tip.
Q320 is added to SET_UP in the touch probe table.
Input range 0 to 99999.9999
Traversing to clearance height Q301: 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
Number of probe points in the plane (4/3) Q423:
Number of measuring points on the diameter. Input
range 0 to 8
Reference angle Q380 (absolute): 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
Calibrate length (0/1) Q433: Define whether the
TNC should also calibrate the touch probe length
after radius calibration:
0: Do not calibrate touch probe length
1: Calibrate touch probe length
Datum for length Q434 (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
