Running a part program
Preparation
1 Clamp the workpiece to the machine table.
2 Set the datum
3 Select the necessary tables and pallet files (status M)
4 Select the part program (status M)
You can adjust the feed rate and spindle speed with
the override knobs.
It is possible to reduce the feed rate when starting
the NC program using the
FMAX soft key. The
reduction applies to all rapid traverse and feed rate
movements. The value you enter is no longer in
effect after the machine has been turned off and
on again. In order to re-establish the respectively
defined maximum feed rate after switch-on, you
need to re-enter the corresponding value.
The behavior of this function varies depending on the
respective machine. Refer to your machine manual.
