Research on Graph-based Recognition of Undercut Features from Molded Part

Shao JianLu ZhenKe Yinglin Zhejiang University, Hangzhou, 310027  
A new graph-based recognition method of undercut features from molded part was proposed. Attributes of node and edge in Face Adjacency Attribute Graph(FAAG) were extended to form Extended Face Adjacency Attribute Graph(EFAAG). Based on these theories, concave, convex and through undercut features were defined accordingly and sub-graphs of the undercut features were recognized from EFAAG of the molded part by graph matching. Feature orientation of each recognized undercut features was determined by visibility map and optimized parting direction was chosen from these feature orientations. The case study shows that the proposed method is available in recognizing the undercut features and improves the efficiency in undercut feature recognition.
