Sheet metal stamped components find extensive use in engineering industry, in particular, in automobile like passenger cars, two wheelers, domestic white goods like washing machines, air conditioning equipment and electrical control equipment like switch gears and switches. The annual turnover in this sheet metal stamping industry itself extends to several thousands of lakhs of rupees. This is assuming importance because the process supplies near net shapes without the need of further machining. But in these sheet metal forming processes particularly in bending , defects such as rupture, wrinkling, galling and Springback in formed parts might occur, whether during or after the process. The Springback phenomenon is the most complex and challenging issue in industry. This work presents a study of spring back in wipe bending metal forming process. Spring back is one of the most sensitive features of the sheet metal forming, which occurs due to elastic recovery during unloading. The main purpose of this work is spring back prediction of sheet metal copper alloy and investigation into the causes of the spring back, such as process parameter, geometry of tools etc. In this work the prediction model of spring back in wipe bending process was developed using finite element method code ANSYS APDL 14.0 and an over bend approach is applied to compensate the spring back and the obtained spring back for different process parameters are validated by analytical method.
