Using M functions

Depending on the configuration of the machine tool, you can also use M functions
(machine functions) for machining operations. You can use M functions to
influence the following factors:
functions on the machine tool, such as switching the spindle rotation and
coolant on and off
In the Milling application mode: the contouring behavior of the tool
the program execution
You can use all M functions as block type in programming and program run.
Further information:
A graphic can also be optionally displayed for calling the M functions in the
program run.
Further information:
The product differentiates between standard M functions and the manufacturer-
specific M functions.
Standard M functions
The product supports the following standard M functions (oriented to DIN 66025/
