Abstract-Recently forming industries faces spring back drawback in forming process like cold drawing, sheet metal forming, bending etc. These forming process resulted permanent deformation by cold forming to create different shapes. Spring back defect taking place during the forming process has been emphasized. The solution to such defect problems was also given. Literature review shows that considerable amount of researches have been conducted in the field of material forming and spring-back optimization process. The present review focuses on the cold forming processes, spring back defect, factors affecting spring back, the various methods used to analyze and optimize the spring back free process. This review also opens future research work to get dimensional stability and least springback.

“…The curvature of each part of the sheet can be individually calculated through equations (4a-c) of the bending moment in the process of the bending formation. 6 The sheet is wrapped around the punch in the contact area between punch and sheet, so the curvature can be seen as a fixed value in the contact area (fully plasticity) between the punch and sheet…”

Based on the flexure theory of plate, and the assumption of plane deformation, an analytic model of U-free bending theory is proposed, which considered the hardening, anisotropy and elastic deformation of the material. Using this model, the change rules of bending force with bending stroke and the formula of target angularity are obtained, and the various factors affecting bending force and rebound are analysed. Furthermore, the results of theoretical calculations, experiments and simulations are compared, which provide the theoretical basis for identifying the parameters of the intelligent controlled free U-bending in wide plate, as well as determine variables of the input and output layer of the predicted model.

“…Paik, et al [7] developed on advanced computer aided manufacture (CAM) system called the changeable die system (CDS) that applied to the cold-forming technique to produce curved metal plates with complex, three-dimensional geometry. Thipprakmas and Phanitwong [8] studied process parameter design of springback and spring-go in V-bending process using Taguchi technique. Sharad and Nandedkar [9] studied the change of some various parameters affecting springback such as the ratio of die radius to sheet thickness, sheet thickness, blank holder force, the coefficient of friction etc.…”

In this paper, the phenomenon of springback and how to reduce this phenomenon were studied experimentally and theoretically. To simulate springback effect and analyze the results theoretically, a special program (finite elements (ANSYS 18.1)) has been used. The simulation of the bending sheet metal has been performed by using a rectangular plate of aluminum alloy (3105) and low carbon steel (1020) with three different thickness (1,1.5,2) mm using die profile radius (50) mm. These parameters have been used to study the effect of type and thickness of metal used with die profile radius on the amount spring back and residual stresses after removing the load. The results obtained for aluminum (3105) and low carbon steel (1020) revealing that, the amount of springback is decreasing with increase thickness of the plate. In addition, the results showed that the amount of springback for aluminum plates is higher than low carbon steel in all cases. The experimental results is in a good agreement with numerical results .
