Many components are needed to be formed into different shapes depending upon their applications. Whenever the component is formed, it is associated with little or more amount of spring back. It is because of the elastic stresses that remain in the bent-up part. When the bending force is removed, the elastic stresses remaining in the bent up part try to relieve and due to relieving of these elastic stresses the formed up component tries to regain its original shape. This movement of metal due to relieving of stresses is called spring back. In this paper, the effect of orientation on the spring back is studied for components with holes and without holes. The components are formed in U shape along the rolling direction, 450 to the rolling direction, and 900 to the rolling direction, with hole and without a hole in the component. Springback is measured and compared for all the formed-up components. It is seen that the spring back is minimum both for components with holes and without holes formed along the rolling direction. It is also seen that for the components with holes the spring back is reduced as compared with the component without the hole.
