| 摘 要： | Design for assembly (DFA) evaluation has preved to be a systematic approach in determining how well a product is designed from the point of view of assembly. Geometric feature, such as symmetry, is an important factor when evaluating the assemblability of a part in it. But the automated detection of symmetry has always been considered to be a difficult problem which requires great effort. Proposed here is a new method for part symmetry automated recognition. The method is based on ray detecting theory and can effectively recognize the symmetry of parts with various shapes. It is of great importance to linking together DFA evaluation procedure with CAD model.
