Interrupting machining
There are several ways to interrupt a program run:
■ Programmed interruptions
■ Machine STOP button
■ Switching to Program Run, Single Block
If the TNC registers an error during program run, it automatically
interrupts the machining process.
Programmed interruptions
You can program interruptions directly in the part program. The TNC
interrupts the program run at a block containing one of the
following entries:
■ STOP (with and without a miscellaneous function)
■ Miscellaneous functions M0, M1 (see „11.5 Optional Program Run
Interruption“), M2 or M30
■ Miscellaneous function M6 (determined by the machine tool
builder)
Interruption with NC STOP button
ú Press the NC STOP button: The block which the TNC is currently
executing is not completed. The asterisk in the status display
blinks.
ú If you do not wish to continue the machining process you can
reset the TNC with the STOP soft key. The asterisk in the status
display goes out. In this case, the program must be restarted
from the program beginning.
Interruption of machining by switching to the Program Run,
Single Block mode of operation.
You can interrupt a program that is being run in the Program Run,
Full Sequence mode of operation by switching to Program Run,
Single Block. The TNC interrupts the machining process at the end
of the current block.
