Panthi, N. Ramakrishnan, M. Ahmed, S. S. Singh, and M. D. Goel, “Finite element analysis of sheet metal bending process to predict the springback,” Mater. Springback Measured The springback angle is the difference between sheet angle αf which formed after raising the load where the part tends to recover elastically after bending and its bend radius becomes larger when the tools are taken away the outer radius of the workpiece and punch angle αi or which called loading bending angle when punch / dies configuration in closed position, as shown in fig.	cache/alkej-437.pdf	txt/alkej-437.txt
