结合FZCAPP系统的开发 ,研究了实用回转体零件计算机辅助工艺设计系统的设计方法 ,认为 :以GT技术为指导 ,按零件结构和工艺的相似性 ,建立零件工序工步集 ,采用特征型面描述法 ,以人机交互的方式输入零件信息 ,采用派生与创成相结合的综合模式生成零件工艺内容的方法 ,既有较高的实用性 ,又有较好的先进性 Combining with the development of FZCAPP system, the design method of computer aided process designing system of practical rotary body parts is studied. It is considered that, with the guidance of GT technology, according to the similarity of structure and process of parts, Method, the way of human-computer interaction to enter the part information, the use of a combination of derivative and create a combination of integrated technology to generate part of the method of content, both high practicality, but also better advanced
