An external sensor is generally mounted on a machine tool in case cutting force information is needed. Mounting the external sensor, however, requires mounting space and lowers the stiffness of the system. We have been developing the sensor-less cutting force monitoring method, which can estimate cutting force without an external sensor by using servo information. The estimation accuracy of this method is influenced by friction force arising on guides and the gravity force is needed to be compensated in z-axis. Therefore, high-accuracy z linear-motor-driven stage applying aerostatic guideways and an air balancer is developed to achieve high-accuracy cutting force monitoring. In this study, the sensor-less cutting force control system is developed applying the sensor-less cutting force monitoring. The cutting force controlled drilling of glass is carried out and its validity is evaluated.
