A New Springback Compensation Method for Sheet Metal Bending Based on Curvature Correction
Abstract:
The dimensional inaccuracy caused by springback is a major problem for most stamping applications. One of the most promising ways to solve this problem is to compensate it by means of appropriate tool shape modifications. In this paper, a new springback compensation method is introduced. A coefficient of curvature correction, which reflects the deviation of the experiment data and the analytical calculation data, is also proposed to redesign the tooling shape. This method was applied to a two-dimensional wavy-shaped part forming case for verification. The experiment results demonstrated that this method is efficient.
