Spring back is the most important phenomenon that affects the accuracy of the sheet metal parts. the important problem because spring back is major forming defect in sheet metal forming using high strength steel sheets. Spring back occurs in metal forming after removal of the load due to elastic recovery of material. It is difficult to develop analytical formula for spring back the formed parts it is highly recommended to use such process parameter, tool geometry that are allow a significantly dimension of the spring back amount of the major defects in sheet metal forming processed. Spring back is influenced by many factors including properties of the sheet materials and processing conditions, Obtaining the desired size, shape depends on the prediction of spring back. By analyzing these parameters, the defects like wrinkling, earing, tearing and spring back is reduced and also we can get the very good quality product.
