Edge effects of metal plate in laser forming
(School of Mechanical Engineering, Shanghai Jiaotong University, Shanghai 200030, China)
Abstract: To search for the new scanning plan that can reduce the bending angle variation and the bending curvatures of the bending edge, an explanation for the causes of the edge effects was given. Six new scanning strategies were proposed through the change of the scanning length of middle and two ends based on the above analyses. Numerical simulations were carried out to study the edge effects using the six new scanning strategies. The simulation results show that the new scanning strategies can improve effectively the quality of the forming parts.
