| Abstract Scope |
In this paper, a novel method of using conformal mapping to design the pre-forging shape is proposed to achieve a reasonable three-dimensional (3D) shape of the pre-forging. Firstly, the 3D final forging was two-dimensional (2D) sliced to simplify the design problem. The new profile of each slice was calculated based on the conformal mapping method. Then, the discrete points on all new profiles were combined into a 3D point cloud for surface reconstruction to obtain 3D model of the pre-forging. Next, four parameters (conformal factor and triaxle scaling factors) were applied to describe the pre-forging shape. Finite element analysis was used to simulate the forging process of the designed pre-forging. Finally, this method was applied to design the pre-forging shapes of different forgings. Through reasonable parameter values, satisfactory pre-forging shapes can be obtained. This method is effective, easy to implement, and has universal adaptation. |
