Research on Part Feature Rule Description and Matching Algorithm based on Topological Relation

The recognition and extraction of part processing features is an preliminary step for intelligent manufacturing, and can significantly facilitate the machining process design and resource allocation. This paper uses SolidWorks software, which is commonly used in the production process, to carry out secondary development. The feature description rules and matching algorithms are designed in common parts based on multi-attribute adjacency graph (MAAG), which ensure the rapidity and accuracy of feature recognition in the manufacturing process. The results of feature recognition in common parts store topological relationships between features, which is beneficial for the determination of co-planar features, co-processing direction features.
