Tool breakage monitoring
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.
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").
