拉深件的生产遍布于军用、民用的各个生产部门,其用量之大也是不言而喻的。因而世界上工业发达国家的大企业集中了较多的人力、物力,从事拉深模CAD的开发。到七十年代中期,国外许多公司已经成功地将计算机技术应用到汽车复盖件生产领域。如美国的通用汽车公司、日本的三菱汽车公司、英国的剑桥大学工业部,美国的康乃尔大学、苏联的国家科学院综合技术研究所等。匈牙利米什科尔茨重工业大学机械系所开发的拉深模CAD/CAM系统,可用于处理一些轴对称件(包括带凸缘件、台阶形工件等)和矩形件。国内, Drawing parts production throughout the military, civilian production departments, the amount of large is self-evident. As a result, large enterprises in industrialized countries in the world have concentrated more manpower and material resources and engaged in the development of CAD for deep drawing. By the mid-seventies, many foreign companies have successfully applied computer technology to the production of automotive cover parts. Such as the United States General Motors Corporation, Japan’s Mitsubishi Motors Corporation, the British Ministry of Industry Cambridge University, the United States Cornell University, the Soviet Union’s National Institute of Technology and other integrated technology. The drawing die CAD / CAM system developed by the Department of Mechanical Engineering at the University of Miskolcz in Hungary can be used to process some axisymmetric parts (including flanged parts, stepped parts, etc.) and rectangular parts. domestic,
