Please note while programming:
HEIDENHAIN only gives warranty for the function of
the probing cycles if HEIDENHAIN touch probes are
used.
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.
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 program a tool call
to define the touch-probe axis.
Pre-position the touch probe so that it is located
approximately above the center of the calibration
sphere.
If you program Q455=0, the TNC will not perform a
3-D calibration.
If you program Q455=1-30, there will be a 3-D
calibration of the touch probe. Deviations of the
deflection behavior will thus be determined under
various angles. If you use Cycle 444, you should first
perform a 3-D calibration.
If you program Q455=1-30, a table will be stored
under TNC:\Table\CAL_TS<T-NR.>_<T-Idx.>.3DTC.
<T-NR> is the number of the touch probe, and <Idx>
is its index.
If there is already a reference to a calibration table
(entry in DR2TABLE), this table will be overwritten.
If there is no reference to a calibration table (entry in
DR2TABLE), then, in dependence of the tool number,
a reference and the associated table will be created.
