一个工艺实例的匹配方法

Instance Matching for Manufacturing Process Planning

提出一个以无向特征依赖图 (UFDG)表达零件特征和存储特征间的相互依赖的拓扑关系 ,通过 UFDG(子 )图同构判别零件之间的相似性、通过零件的其它特征参数的相似性选择进一步筛选工艺实例的匹配方法 .

A way of representing the relationship of different features in a part termed Undirected Feature Dependency Graph(UFDG) is proposed. Base on this approach, the similarity of process plan instances of different parts can be evaluated by the subgraph isomorphism method, after that, a filter function is performed to scale down the instance set, then the user can select instance from it to start his process plan design. This approach has the advantages of catholicity and fine resolving performance.
