Managing more than one block of calibrating
data
If you use several touch probes or measuring contacts arranged in a
cross shape on your machine, you must also use several sets of
calibration data, if required.
To be able to use more than one block of calibration data, you must set
bit one in Machine Parameter 7411. Although the calibration data
(length, radius, center misalignment, and spindle angle) are calculated
in the calibration menu, you must always save them in the tool table
TOOL.T under a tool number that can be selected in the calibration
menu (see also User's Manual, section 5.2, “Tool Data”).
Execute the calibration function (as described previously).
Enter the tool number in the corresponding input box.
Enter the calculated calibration data in the tool table by pressing the
ENTER-R IN TOOL TABLE or ENTER L IN TOOL TABLE soft key.
If you use the touch probe afterwards, you must first
activate the corresponding tool number with a tool call
before executing a touch probe cycle, regardless of
whether you wish to run the touch probe cycle in
automatic mode or manual mode.
You can view and edit the calibration data in the calibration
menu, but you must make sure to write the changes back
into the tool table by pressing the ENTER R IN TOOL
TABLE or ENTER L IN TOOL TABLE soft key. The TNC
does not write the calibration values into the table
automatically!
