Rapid Prototyping(RP) is an efficient method for rapid design verification and trial manufacturing. In order to improve their unique characteristics according to the working principles. Variable Lamination Manufacturing process and corresponding CAD/CAM system is developed. The objective of this study is to improve dimensional accuracy of VLM-ST process, and it can be done by offset for cutting error correction, cutting path correction for sharp edge and reference shape generation. To verify the proposed algorithms, they applied to three-dimensional shapes, such as spanner and mechanical part.

CAMPfonn2D is a Finite Element Method (FEM) based process simulation system designed to analyze two dimensional (2D) flow of various metal forming processes. It enables designers to analyze metal forming processes on the computer rather than the shop floor using trial and error and provides vital information about material and thermal flow during the forming process to facilitate the design of products. CAMPfonn2D can be used by companies, research institutes and industrial applications to analyze forging, extrusion, drawing, heading, upsetting and many other metal forming processes. Also, process simulation using CAMPfonn2D can be instrumental in cost, quality and delivery improvements at leading companies. Today's competitive pressures require companies to take advantage of every tool for rapid manufacturing of well-designed product. So, the preprocessor of simulation program must be easy to use to speed-up design. In this paper, we introduce new version of Preprocessor and show how easy to use it. And, Preprocessor will prove itself to be easy and extremely effective.

본고에서는 일본 중견기업의 위상, 특징, 관련 정책을 검토함으로써 우리나라에서의 중견기업 정책의 방향을 모색하고자 한다. 일본의 경쟁우위업종인 기계, 전자부품업의 출하와 고용비중은 여타 업종보다 높아, 그 저변에 두터운 중견기업이 존재하고 있음을 알 수 있다. 일본의 중견기업 육성정책은 연구개발과 환경대책을 위한 기업간 제휴 유도라는 측면에서 간접적으로 지원하고 있다. 우리나라도 특정 정책사업에 있어서 기업간 협력 유도를 통하여 중견기업을 육성할 수 있을 것이다.
