A Finite Element Analysis of the effects of punch radius on springback in a V Bending process of a Titanum Alloy Ti-۶AI-۴V sheet metal piece

Springback is a very common and critical phenomenon in sheet metal forming operations, which is caused by the elastic redistribution of the internal stresses after the removal of deforming forces. Springback compensation is absolutely essential for the accurate geometry of sheet metal components. This paper presents a finite element model to simulate the V Bending process of a ۱mm thick Titanum Alloy Ti-۶AI-۴V workpiece in order to analyze the effects of punch radius on the amount of springback in this process. The simulations suggest that the smaller the punch radius the less springback accurse during the process.
