17.5 CALIBRATE TS (Cycle 460, DIN/ISO:
G460, software option 17)
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.
