现代汽车及起亚汽车的研究论文发表会 利用三维数字数据制造车体和开发工程系统 Development of Body Manufacturing and Engineering System for 3D Digital Data Hwang,Woo Dong * Jung,Jae Ho Song,Song Chun Kawk,Ho Chul (Body Manufacturing Engineering Team 1) The current manufacturing preparation task has a low work accuracy and a long task time because 2D based manual operations depending on experience and intuition. This paper is about a program development optimizing the task of the current. This program uses 3D CATIA data as it is in general computer without the conversion and move automatically the document creation. This program is divided to the three modules( 3 D structure check, 3 D planning drawing and simulation, 3D Quality analysis).As the results of this research,The quality of current manufacturing preparation task was greatly improved and the planning drawing and equipment preparation period was considerably reduced and the design degree of freedom to the feedback of task data was enhanced Key Word : 3D structure check, 3D planning drawing and simulation, 3D Quality analysis 多了. DMES 是利用三维数字信息技术, 有效 1. 导言 率地实行生产准备工作的一体化的系统概念. 请参考 Table1 的 DMES 概念. 1.1 研究背景 迎接 21 世纪的汽车产业正在面临着符合 多种多样的市场要求的同时增大赢利, 走向世 界为基础的改革要求. 在这样的情况下, 著名 的世界级汽车公司曾开始研究以 CE(Concurre nt En-gineering)方式为基础的最适当的新车 开发过程和生产方式, 以便于灵活地对待市场 变化和生产价格低廉而质量较高的汽车.随着 车辆生命周期越来越短, 新车开发期间的缩短 和同时生产体系的构筑是所有制造行业的最
