Abstract: In many manufacturing processes involving sheet metal fabrications, springback is a major concern, complicating tooling designs. This paper develops an effective analytical model to predict springback for a straight flanging process. The model calculates the final springback angle by conducting bending moment computation, geometry and configuration calculation, and springback calculation. The predicted results are examined against our own experimental data and experimental results from independent papers. The predicted results show a good agreement with the corresponding experimental results published in the literature. Sensitivity and trend analysis of springback are efficiently obtained.

Keywords: analytical model; sheet metal forming; springback; straight flanging process.
