Abstract
This paper proposes a monitoring technique for the in-process measurement of cutting force and the prediction of tool breakage in the high speed slotting with the small-diameter end mill, which is based on the newly developed visualization system with high-speed CCD camera, image acquisition and image processing. This system is able to measure the tool deflection and to predict the cutting force in process, it is useful for the monitoring of the cutting state.
In order to control the constant cutting force in process, the cutting force that this system predicted was used for the feedrate override control. As a result, the prevention of tool breakage and the control of the cutting force were confirmed by the feedrate override control.
