在模具型腔光整加工中,多功能抛光机的出现,超声、电解和机械复合抛光新工艺的应用,与传统的单纯依靠工人的经验进行操作的工艺状况极不适应。本文介绍了一个针对DFM-1型电脑复合模具抛光机建造的自动编制工艺规程的专家系统,讨论了其原理、结构和特点,为CAPP及专家系统技术的应用开拓了一个新的领域。本系统的基本原理和用人工智能中规划的方法自动生成工艺路线,以及用产生式系统确定工序数目和顺序的方法也适用于机械零件切削加工和产品装配CAPP系统的建造。
In the mold cavity finishing, multi-function polishing machine, ultrasound, electrolysis and mechanical polishing new technology applications, and the traditional relying solely on the experience of workers to operate extremely poor condition of the process. This paper introduces an automatic expert system for DFM-1 computer composite mold polishing machine, discusses its principle, structure and characteristics, and opens up a new field for the application of CAPP and expert system technology. The basic principles of this system and the method of automatically generating process routines using artificial intelligence, as well as the method of determining the number and order of processes with a production system, also apply to the construction of CAPP systems for machine parts machining and product assembly.
