  • 본 연구에서는 공구선정 작업의 자동화를 목표로 하였다.공구선정을 완전 자동으로 행하기 위해 해결해야 할 문제는, 현재 공구대(turret)에 장착되어 있는 공 구중에서 어떤 공구를 얼마칸큼 직선, 회전 이동시키면 판재 경계와 정확하게 일치하 는가 하는 문제와, 복잡한 형상의 펀칭을 위해선 효과적인 공구조합은 어떻게 해야하 나 하는 문제로 귀결되므로 이 두가지 문제의 해결방안을 기술한다.

  • A data structure representing 3-D objects was designed for the personal computer. It is very simple to be used in the personal computers which have small memory and low speed. A homogeneous transformation for developing 3-D objects was derived. Each developing procedure consists of five transformations : one translational-three rotational-one translational. Developing a solid is a creative work. So the results of developing vary with the order of surfaces to be developed. One method to reduce the length of seam was considered. The programs used in this study were written in Pascal and Assembly and a modeller that generates 3-D primitives was included. This program is an interactive dual-screen system. While all the menus in Korean are displayed at the monochrome monitor, the development figures with projective views are drawn at the color monitor. The program has wide applications for plate works.
