Abstract
In this paper, a cutting force measurement technique by using image processing was proposed to optimize cutting process and detect abnormality in cutting operation. In the technique, we captured images of end mill by a small CCD camera and mirrors during cutting process from x and y direction to determine deflection of a tool and then estimated cutting force in x-y plane. In optimization, relation between cutting force and cutting volume was formulated and optimization effect was verified by the proposed equipment. In detection of abnormality in cutting operation, relation between tool wear and RMS value of cutting force was estimated. Finally, we optimized cutting condition and detected abnormality in cutting operation very well.
