“…The obtained result showed that the springback increased with increasing coating thickness, punch radius, punch travel, die radius, die opening, and punch velocity. It has also been observed that 90° orientation show higher springback than 0° orientation [28].…”

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.

“…For the same die opening, the punch has to travel a longer distance in smaller die angle than the larger one. The increase in punch travel increases the bending moment which in turn increases the springback [19]. When the sheet thickness increases from 1 mm to 2 mm, the springback reduces.…”

The bimetallic sheets are used in the industrial sheet metal products to meet the demands of multifunctionality. The bending behaviour of bimetallic sheet is contributed by individual layers of the sheet and it is entirely different from the monolithic material. In this study, V-bending experiments are carried out to understand the springback, bend force and thickness change of Al-Cu clad sheets. The effect of different parameters such as sheet thickness, sheet setting condition, die angle, die opening and punch radius have been investigated. The results indicated that springback is more for smaller die angle, wider die opening and larger punch radius. Increase in die angle, increase in die opening or decrease in punch radius decreases the bend force. The clad sheet thickens at Al/Cu setting condition whereas it thins at Cu/Al setting condition. This thinning or thickening of the sheet influences the springback and bend force.

Bending in a V-die has been well covered in the literature and the results have been used to indicate the outcome of bending in cold roll forming. However, recent work comparing springback between roll forming and single step bending has found lower springback in the roll forming process compared to single step bending. Roll forming is an incremental bending process and in this study a V-section was formed in a single operation and in multiple steps and the springback determined. The springback in V-die forming was significantly reduced by incremental forming. This suggests that the lower springback determined in roll forming compared to single step bending may be related to the incremental nature of the roll forming process.
