Abstract
Milling is one of the most importyant metal cutting processes. If we measure the cutting force, we can make cutting process optimum, prevent tool breakage, and improve efficiency of process. Especially in the case of using a micro end mill, It is very difficult to dentify whether cutting process is good or not. In this paper, we proposed the cutting force measurement technique by using image processing. In the technique, we captured images of end mill during cutting process from x-y direction, determined deflection of the tool and then estimated cutting force. Finally we can estimate small cutting force in two-dimension plane and determined the experimental equation of cutting force based on the measured data.
