A Study on the Burr Minimization of Drilling Process by Optimal Velocity Profile Tracking
이상적 속도 궤적을 이용한 드릴링 공정의 버 최소화에 관한 연구
Abstract
At the exit stage of drilling, the burr generates and deburring process is required to remove it. Since the additional process reduces productivity, a burr minimization technique is necessary in the servo system of drilling machines. In this research, cutting force is modelled with tool geometry and the optimal velocity profile with which the desired cutting force maintains is generated to minimize burr. Experiments show that the proposed velocity profile tracking effectively minimizes burr compared to the constant velocity feed.
