Tool breakage monitoring
This function works only:
If the tool table is active.
If tool monitoring is switched on in the cycle
(enter Q330 not equal to 0).
If the breakage tolerance RBREAK for the tool
number entered in the table is greater than 0 (see
also the User's Manual, section 5.2 "Tool Data").
The TNC will output an error message and stop program run if the
measured deviation is greater than the breakage tolerance of the
tool. At the same time the tool will be deactivated in the tool table
(column TL = L).
Reference system for measurement results
The TNC transfers all the measurement results to the result
parameters and the log file in the active coordinate system, or
as the case may be, the shifted and/or rotated/tilted coordinate
system.
