7 Programming: Miscellaneous functions 86
7.1 Entering Miscellaneous Functions
M and STOP
With the TNC's miscellaneous functions - also called M functions -
you can affect:
■ Program run, e.g., a program interruption
■ Machine functions, such as switching spindle rotation and coolant
supply on and off
■ Contouring behavior of the tool
The machine tool builder may add some M functions
that are not described in this User's Manual. Your
machine manual provides more detailed information.
M functions are always entered at the end of a positioning block.
The TNC then displays the following dialog question:
Miscellaneous function M ?
Only enter the number of the M function in the programming
dialog.
In the MANUAL OPERATION operating mode, the M functions are
entered with the M soft key.
Please note that some F functions become effective at the start of
a positioning block, and others at the end.
M functions come into effect in the block in which they are called.
Unless the M function is only effective blockwise, it is canceled in a
subsequent block or at the end of the program. Some M functions
are effective only in the block in which they are called.
Entering an M function in a STOP block
If you program a STOP block, the program run or test run is
interrupted at the block, for example for tool inspection. You can
also enter an M function in a STOP block:
ú To program an interruption of program run,
press the STOP key.
ú Enter miscellaneous function M
