摘　　要：为充分利用已有的设计信息,实现设计信息到制造信息的快速转换,针对箱体类零件的几何特点,提出以面为中心的,基于痕迹与规则的混合特征识别算法。实例证明,该文的识别算法能够有效识别箱体类零件中的常用加工特征,并在开发的CAD/CAPP集成系统中利用遗传算法实现了对所获取的特征信息的充分利用,制定出合理的工艺路线。CAD/CAPP集成技术能够有效地缩短产品开发周期,提高工艺人员的工作效率,降低成本。In order to fully utilize the existing design information and realize the transitionfrom design information to manufacturing information, according to geometric characteris- tics of box-type parts, this paper focuses on surface and proposes a rule and hint basedhybrid recognition method, which, as proved, effectively realizes the common machining feature recognition, and the developed CAD/CAPP integrated system achieves full use ofthe acquired feature information using genetic algorithm and can effectively develop a rea- sonable process. The CAD/CAPP integration technology can effectively shorten the productdevelopment cycle, while improving the efficiency of the process engineer to reduce costs.
