N2 - Springback is defined as a geometric defect, which occurs due to elastic recovery in the part after it has been unloaded. This challenge is most common in lightweight alloys as well as in advanced high strength steels. The materials, which exhibit lower elastic modulus or higher tensile strength, would be more prone to springback. In this paper, a novel patented technique is introduced to eliminate the springback by using rollers in the forming tool. It was found that due to the rotation of rollers in the tool during forming, reduces the stress in the part and, thus reduces the springback.
