17.5 CALIBRATE TS (Cycle 460, DIN/ISO:
G460)
With Cycle 460 you can calibrate a triggering 3-D touch probe
automatically on an exact calibration sphere. You can do radius
calibration alone, or radius and length calibration.
1 Clamp the calibration sphere and check for potential collisions.
2 In the touch probe axis, position the touch probe over the
calibration sphere, and in the working plane, approximately over
the sphere center.
3 The first movement in the cycle is in the negative direction of
the touch probe axis.
4 Then the cycle determines the exact center of the sphere in the
touch probe axis.
Please note while programming:
HEIDENHAIN only gives warranty for the function of
the probing cycles if HEIDENHAIN touch probes are
used.
The effective length of the touch probe is always
referenced to the tool datum. The machine tool
builder usually defines the spindle tip as the tool
datum.
Before a cycle definition you must have programmed
a tool call to define the touch probe axis.
Pre-position the touch probe in the program so that
it is located approximately above the center of the
calibration sphere.
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
