Abstract
Today there is widespread usage of high strength steels (HSS), and ultra
high strength steels (UHSS) in the manufacturing industry. Especially in
the automobile industry for the rigid and light weight chassis components
made out of high strength steel. 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.
