前言使用电子计算机对模具进行辅助设计和制造(CAD/CAM),是提高模具生产效率和模具制造质量的有效途径之一。国外早在50年代就开始了CAD/CAM的研究,60年代已开始在模具生产上应用,70年代已形成了不少成熟的系统并取得了显著效果。从早期应用于冲裁模,发展到用于拉延模、注塑模和锻模等。目前,我国的计算机技术正在日益发展和普及,因此将计算机技术用于模具设计和制造,不但有了可能,而且是十分必要的。
Preface The use of computer-aided design and manufacture of molds (CAD / CAM) is one of the effective ways to improve the mold production efficiency and mold manufacturing quality. As early as in the 1950s, CAD / CAM started its research in foreign countries. In the 1960s, the application of mold CAD / CAM was started. In the 1970s, many mature systems have been formed and achieved remarkable results. From the early application of blanking die, developed for drawing dies, injection molds and forging dies. At present, computer technology in our country is being developed and popularized day by day. Therefore, it is not only possible but also necessary to use computer technology for mold design and manufacture.
