The Study on the Cutting Force Prediction in the Ball-End Milling Process at the Random Cutting Area using Z-map
Z-map을 이용한 임의의 절삭영역에서의 볼 엔드밀의 절삭력 예측에 관한 연구
Abstract
In this study, a method is proposed for the cutting force prediction of Ball-end milling process using Z-map is proposed. Any types of cutting area generated from previous cutting process can be expressed in z-map data. Cutting edge of a ball-end mill is divided into a set of finite cutting edges and the position of this edge is projected to the cross-section plane normal to the Z-axis. Comparing this projected position with Z-map data of cutting area and determining whether it is in the cutting region, total cutting force can be calculated by means of numerical integration. A series of experiments such as side cutting and upward/downard cutting was performet to verify the simulated cutting force.
