随着世界工业的进步和人们生活水平的提高,产品的研发周期越来越短,设计要求响应时间短。特别是结构设计需做些修改时,前期的模具制造费用和制造工期都白白地浪费了。因而模具设计和制造成为新产品开发的瓶颈。计算机辅助工程的发展,使得传统产业与新技术的融合成为可能。三维CAD可以把设计从画图板中解放出来,大大简化了设计者的设计过程,减少出错的几率。并且随着快速成型(RP)技
With the progress of the world’s industry and people’s living standards, product development cycle is shorter and shorter, the design requirements of the response time is short. In particular, the structural design needs to be modified, the previous mold manufacturing costs and manufacturing deadlines are wasted. Mold design and manufacturing become the bottleneck of new product development. The development of computer aided engineering makes the integration of traditional industries and new technologies possible. 3D CAD can liberate the design from the drawing board, which greatly simplifies the designer’s design process and reduces the chance of error. And with rapid prototyping (RP) technology
