论CAPP的创成模式

本文论述了系统运用成组技术原理，提出了检索，创成综合模式。其特点是按相似零件组编组工序、工步词典，以工序工步词典为索引建立相应的工艺决策规则。在系统软件实现方面，运用编译原理、构造词法、语法分析器，对规则或知识进行预处理，形成特定的语法结构，使知识库与推理机相互独立。

The Generative Model of a Computer Aided Process Planning

In this paper,the authors described the system based on the principle of Group Technology,Combined Variant Approach with Generative Approach to form their Compound Approach whichdistinguishing feature is to be built the process and the work step dictionaries and then to draw upthe part rules for the process decison according to the dictionaries. The inperential engine is inde-pendant of the knowledge and rules , The principle compilation is applied to build the token and the parse analysical program which analyses the rules to take form the structure of grammar spe- cially while the rules is pretreatment by analysical engine,they join to the knowledge base of the process.
