摘　　要：本文介绍了活塞CAD/CAM技术内容和发展现状 ,在三维有限元的基础上 ,采用面向对象的技术和专家知识型的数据库建立活塞的实体模型 ,并在进行有限元的剖分和边界条件的确立后对分析结果优化设计 ,最后将设计好的实体通过在计算机上自动生成NC程序 。The article introduces the technical contents and development status of piston CAD/CAM.On the basis of three dimensional FEM analysis, applying the solid model whose piston is set up with the technology which is orient object and expert database,making the advanced design of the analysis result after the creation of FEM meshes and the establishment of boundary conditions.Finally,the designed object goes through the NC procedure,which is automatically developed in the computer,develops and establishes a whole set of piston CAD/CAM integration based on the three dimensional solid model.
