Effect of Process Parameters on Spring Back In Deep Drawing: A Review
Sachin S Chaudhari,  Navneet K Patil
Abstract - Spring back is one of the most important phenomenon that affects the accuracy of the sheet metal parts. In order to get tight tolerances for the formed parts it is highly recommended to use such process parameters/tool geometry that allow a significantly diminishing of the spring back amount. In this sense, good results could be obtained by applying some methods and techniques of optimization. Optimization of process parameters in sheet metal forming is an important work to reduce manufacturing cost. To determine the optimum values of the process parameters, it is necessary to find their control on the deformation behavior of the sheet metal. The significance of three important process parameters as, punch nose radius, blank holder force and friction coefficient on the deep drawing characteristics, die shoulder radius, sheet thickness, radial clearance etc. of a mild steel cup will be determined. In this paper basic review is presented based upon optimization of process parameter in deep drawing process with the use of different techniques. Verity literatures of research spotlight on parameters that affect most in deep drawing process. By analyzing these parameters, the defects like wrinkling, tearing, earing and spring back is reduced and also we can get the good quality product.
