7.1 Entering Miscellaneous
Functions M and G38 (STOP)
Fundamentals
With the TNC’s miscellaneous functions—also called M functions—
you can influence:
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 displays the following dialog question:
Miscellaneous function M?
You usually enter only the number of the M function. 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 M 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 G38 block
If you program a G38 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 U U U To program an interruption of program run, press the
STOP key.
U U U 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.
