Research on Automatic Generation Method of 3D Sheet Metal Process Model
A fast method for generating sheet metal process models is proposed to address the problem of difficulty in automatically generating process models in 3D process design of sheet metal parts.Firstly,utilizing the data and topological relationships of the design model,the bending and internal features of the sheet metal are automatically identified.Then,the bending features are used to calculate the sheet metal flattening matrix,and the boundary data and flattening matrix of the surface are used to calculate the sheet metal unfolding part and process model.A prototype system for generating sheet metal process models is developed,and the feasibility of the above method is verified.The results indicate that the proposed method can automatically generate sheet metal process models and ensure the accuracy of process model generation.
