A Study on Formed Tool to Machine Milli-structure Mold
미세구조물 금형가공을 위한 총형공구에 관한 연구
Abstract
This paper presents the formed tool to machine a milli-structure mold. The formed tool is used to machine the geometrical shape of bearing rubber seal for precision machining. The bearing rubber seal has milli-sized complex geometry. Because it is difficult to machine the unique shape exactly by the conventional tool, the formed tool is used in machining die of the bearing seal. In this paper, it is performed to investigate properties of the formed tool; tool wear, cutting force and machined surface roughness. Tool wear increases rapidly with clearance angle Increase. Thus, the dimension accuracy is affected by the clearance angle.
