Effect of spring-back and spring-forward in V-die bending of St1403 sheet metal plates
Today there is widespread usageof high strength steels (HSS), and ultra high strength steels in the manufacturing industry. Especially in the automobile industry for the rigid and light weight chassis components made out of high strength steels. During sheet metal forming material undergoes plastic deformations and after the process of forming and taking out of the tool, formed sheet metal plate try to take previous position and elastically deforms. This deformation is called elastic spring-back. Special version of this elastically unloading is called spring forward. It can be seen in V-die bending with small punch radius, and small punch angle which is shown in this paper.
