摘　　要：介绍了一种CAD/CAPP集成环境下基于三维模型的工序图自动生成系统。该系统充分利用已有的信息,采用逆 向动态生成法生成各道工序图。分析了系统的信息流向及信息需求,讨论了自动生成过程中遇到的难点,利用三维图形 处理技术和参数修改法解决零件模型的动态修改和自动生成。为解决工序图的自动生成提供了一条新的途径。The 3D_model based automatic generation of parts processing sketches under CAD/CAPP integrated environment is introduced . The method of inversed generation is employed in order to utilize effectively information which has existed. This paper analyses key points about automatic generation, such as information flows and requirement of information. Processing sketches are generated by modify 3D_ model part through methods of Parameter Editing and Boolean Operation. The paper gives a new easy way to generate processing sketches automatically under CAD/CAPP integrated system.
