And to predict future individual machine tool diagnostics and life cycle management of machine tools.
Most of the conventional machining centers, which currently use machining centers, are used off-line so that only the field workers know the machining conditions and machine tool conditions.
That is, a monitoring device capable of monitoring a measurement result of the sensor and a monitor attraction are required in a unit factory equipped with the machining center, provided with a sensor capable of measuring a machining state and a state of a machine tool in the machining center .
