| Abstract: | The graph matching based on machining benchmark is a key point of the reconstruction of 3D process model.Firstly,the projection of three-dimensional process model is associated with current process drawing.Then,types and features of machining benchmark are analyzed.Subsequently,a method of get the machining benchmark and the concept of benchmark graphics is proposed in this paper.Finally,a series of examples are presented to demonstrate the feasibility and effectiveness of the proposed approach. |
