摘要
为提高计算机辅助工艺设计(CAPP)系统的工艺适应性,增强产品工艺变型设计的能力,提出了一种基于事物特性表(SML)的CAPP系统设计方法。根据事物特性表原理及主文档技术,介绍了一种面向工艺重用的CAPP系统构建方法及相关使能技术,并采用本体技术,构建了CAPP领域信息层次结构模型。据此设计了一种PDM框架下,面向工艺变型设计的系统体系结构,以满足用户工艺定制的市场需求。最后给出了面向工业汽轮机转子加工工艺变型设计的系统开发实例。
In order to improve the process applicability,practicality and enhance the ability for process variant design,a design methodology for computer aided process planning(CAPP) based on tabular layouts of article characteristics(SML) was proposed.Based on principles of tabular layouts of article characteristics and the technique of master documents,an ideology and technologies of process reuse for developing CAPP system were introduced.The information hierarchy model of CAPP system was constructed based on ontology and knowledge management.And architecture for CAPP system faced the process reuse was developed based on the theory above.The process diversification and individuation could be adapted by this CAPP system.
