The automotive industry is widely uses the forming processes. Springback is a significant issue associated with forming processes. Springback is caused because of elastic stresses present in bent areas. These residual elastic stresses try to get relieved when the punch is retracted it causes the movement of the formed-up parts called springback. In this paper, the effect of holes on sheet metal components (such as base, corner, and sidewall of the U shape component) and the spring back is investigated. The results obtained by finite element analysis (FEA) are compared with the experimental results. Further, the size of the hole in the base wall of the U shape component on the springback is studied. For all locations of holes, i.e. the hole in the base wall, corner, and sidewall, a decrease in the springback is observed. But the presence of a hole in side wall has shown more decrease in springback as compared with hole in the base wall and corner and also, with an increase in the size of the hole the decrease in springback is observed.
