Abstract

A new springback compensation system based on springback mechanics is developed. The cause of springback is the bending moment before springback. To compensate the tool shape, it is necessary to satisfy the springback mechanical equation which is expressed by curvature and bending moment. In this system, the bending moment before springback is designed considering the springback mechanical equation. Actually, the optimum bending moment distribution is designed by modifying the design parameters such as curvature and punch load in this system so that the metal sheet is deformed into the desired shape. In the modification process of the design parameters such as curvature and punch load, the sequential response surface method is used to optimize them. When the proposed method was applied to V-bending, it was found that it was effective because the convergence rate is great and not only the curvature but also the punch load can be obtained.
