基于工作流和集成化物料清单树的CAPP系统

在计算机辅助工艺设计系统中,面向产品全生命周期工艺设计的流程化与工艺数据的管理尤其重要.为解决传统的计算机辅助工艺设计系统在这些方面存在的问题,探讨了工作流技术在基于Web集成化物料清单树的计算机辅助工艺设计系统中的应用,提出了集成化物料清单树的概念,以集成化物料清单为主线,分析了计算机辅助工艺设计系统工艺流程,阐述了基于浏览器/服务器和客户机/服务器模式的计算机辅助工艺设计系统的功能、体系结构及其实现机制,并在此基础上分析了工艺工作流管理器的关键技术.最后,从物料信息编码、集成化物料清单树的组织节点设计、设计物料清单向工艺物料清单的转化,以及程序实现技术等方面详细分析了集成化物料清单树的实现机制.

Computer aided process planning system based on workflow and integrated bill of material tree

It is extremely important for procedure of process design and the management of process data for product life cycle in Computer Aided Process Planning(CAPP) system,but there are many shortcomings with traditional CAPP system in these aspects.To solve these problems,application of workflow technology in CAPP system based on web-integrated Bill of Material(BOM) tree was discussed,and the concept of integrated BOM tree was brought forward.Taking integrated BOM as the thread,CAPP systematic technological process was analyzed,and the function,system architecture and implementation mechanism of CAPP system based on Browser/Server and Customer/Server modes were expatiated.Based on it,the key technologies of workflow management device were analyzed.At last,the implementation mechanism of integrated BOM tree was analyzed from viewpoints of material information encoding,organization node design of integrated BOM tree,transformation from Engineering BOM(EBOM)to Process BOM(PBOM)and the programming implementation technology.
