Research on Mold’s Reverse Modeling and Basic Surface Repair

Abstract

Reverse engineering is used to obtain mold’s numerical point cloud. The key is to get mold’s defective area and boundary’s features information. Then its original model of mold’s defective parts is built, and combined with bi-cubic B-spline to control vertex, the abutting of curves and surfaces, and value iteration technologies for integrate modeling of defect molds.Using finite element analysis and multiple technologies to analyze and amend, the model is repeated revised until a mold’s complete model is obtained.
