Abstract:
Bending is one of the most frequently used process in manufacturing industry. The bending operation involves springback, which is elastic recovery of the part during unloading. It is still a practical problem to predict the final geometry of the part after springback. To resolve that, this experimental study investigates the effect of punch displacement, sheet thickness, friction coefficient and material type during the sheet metal bending process under room temperature condition. Furthermore, the effect of R/t ratio and clearance is also studied. The amount of springback, total deformation, the total equivalent plastic strains, and the equivalent von Mises stresses are also observed. Moreover, the finite element method results are compared with experimental results.
