NC (Numerical Control) machine tools is the device which automated operation of a machine tools by numerical control, and it is greatly contributing to a trial production or manufacturing efficiency-ization at a factory. Machine operation of the NC machine tools is automated, however a human operator needs to determine a processing parameters. An inappropriate parameter causes high loading state operation or cutting vibration, and NC machine tools position accuracy become worse. Introducing force control in NC machine tools has advantages, such as reduction of machine load, and suppression of vibration. For force control in NC machine tools, it is necessary to attach a force sensor which is expensive and fragile. In this paper, force sensor-less cutting force detection is proposed. Finally, validity of proposed method is verified by experiment.
