7.1 Entering Miscellaneous Functions M and STOP
7.1 Entering Miscellaneous
Functions M and STOP
Fundamentals
With the TNC’s miscellaneous functions – also called M functions –
you can affect:
n Program run, e.g., a program interruption
n Machine functions, such as switching spindle rotation and coolant
supply on and off
n Contouring behavior of the tool
You can enter up to two M functions at the end of a positioning block.
The TNC then displays the following dialog question:
Miscellaneous function M ?
You usually enter only the number of the M function in the
programming dialog. Some M functions can be programmed with
additional parameters. In this case, the dialog is continued for the
parameter input.
In the Manual Operation and Electronic Handwheel modes of
operation, 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:
U To program an interruption of program run,
press the STOP key
U Enter miscellaneous function M
Example NC blocks
The machine tool builder may add some M functions that
are not described in this User's Manual. Refer to your
machine manual.
