并行设计思想在开发CAPP中的应用

Application of Concurrent Design in Developing CAPP

探讨并行设计环境下基于特征模型的工艺设计过程，提出通过关联特征约束推理和特征分组，实现加工工艺方案优化的方法。分析引起产品制造问题的原因，提供产品设计上的改进意见，或对设计知识规则进行更新，实现产品设计与工艺设计的双向动态控制和并行求解。

This paper expounds feature model based process planning procedure within concurrent design environment, presents the principles for realizing production planning optimizing by means of interacting feature constraints and feature clustering. The Reasons causing manufacturing faults are analyzed to improve product design or update some design rules. As a result, process planning and product design are bidirectionally dynamically controlled and concurrently resolved.
