Calibrate Ts (Cycle 460, Din/Iso: G460, Software Option 17) - HEIDENHAIN TNC 620 User Manual

16.6 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.
A measuring log is created automatically during calibration. The
log file is named TCHPRAUTO.html. This file is stored in the same
location as the original file. The measuring log can be displayed in
the browser on the control. If a program uses more than one cycle
to calibrate the touch probe, TCHPRAUTO.html will contain all the
measuring logs.
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 warrants the function of the touch
probe 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.
A measuring log is created automatically during
calibration. The log file is named TCHPRAUTO.html.
