Displaying calibration values
The compensation factors and force ratios are stored in the TNC for
later use whenever the measuring touch probe is needed.
You can display the stored values on the screen by pressing the 3D
CAL soft key.
Storing calibration values in the TOOL.T tool table
If you conduct measurements during program run, the compensation
data for the touch probe can be activated from the tool table via a TOOL
CALL.
To store the calibration data in the TOOL.T tool table, enter the
tool number in the calibration menu (confirm with ENT) and then press
the ENTER R IN TOOL TABLE soft key.
The TNC stores the stylus radius 1 in the R column, and the stylus
radius 2 in the R2 column.
This function is only available if machine parameter 7411
= 1 is set (activate touch probe data with TOOL CALL), and
tool table TOOL.T is active (machine parameter 7260 not
equal to 0).
