Study on control of Tool Life in End Milling Processes

In order to perform high speed machining, it is important to develop a support system that can monitor the machining process, and optimize machining conditions adaptively. In this research, we propose a long-term monitoring scheme of the tool wear and a cutting force control strategy. First, the cutting force is monitored only at every “check point” set on the tool path. The federate profile is updated at every check point, such that the desired cutting distance can be machined before reaching the end of tool life. The effectiveness of the present approach is experimentally investigated by cutting experiments.
