NC MACHINE TOOL FILE (MTF)
WARNING
The initial values in the MTF (machine tool file) listed below
are different from those used for a production run. Actual
setting values vary with the machine. For details, refer to the
manual provided by the machine tool builder. If these data
values are not set appropriately for the actual machine
being used, correct NC data cannot be prepared.
Machining with incorrect NC data may result in the tool
colliding with the workpiece and/or machine, or forced
machining occurring, possibly causing damage to the
machine and/or tool itself, or injury to the user.
