Displaying calibration values

The TNC saves the effective length and effective radius of the
touch probe in the tool table. The TNC saves the ball-tip center
offset of the touch probe in the touch-probe table in the CAL_OF1
(principal axis) and CAL_OF2 (secondary axis) columns. You can
display the values on the screen by pressing the TOUCH PROBE
TABLE soft key.
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. When running a touch probe cycle in the Manual
Operation mode, the TNC saves the measuring log under the name
TCHPRMAN.html. This file is stored in the folder TNC: \ *.
Ensure that the tool number of the tool table and
the touch-probe number of the touch-probe table are
correct. This is regardless of whether you want to
use a touch-probe cycle in automatic mode or Manual
operation mode.
