Performance of the Drills with Deburring Inserts
디버링 기구를 내장한 드릴의 성능에 관한 연구
Abstract
This paper describes the design and development of drills with deburring inserts. The drills can be used to drill holes and deburr the edges of the drilled holes simultaneously. The drills incorporate deburring inserts within the shank. The insert consists of a fixing base, a cantilever spring and a cutting tip. The stiffness of the cantilever spring and the details of the cutting tip play a central role for the successful deburring performance. The deburring performance is also governed by the conditions of the drilling burr best described by the burr control chart suggested by Dornfeld. With careful burr control, successful deburring is obtained by the drills with deburring inserts.
