Abstract

Springback is the geometric change made to a part at the end of the forming process. This happens when the part has been released from the forces of the forming tool and due to uneven force distribution along the cross section. During the development of tools, Springback is compensated by software in order to remove the component from the tool to get the required dimensions. As a result, intense tryout loops that occur at a very late stage in the development of the tool can be reduced to a minimum. Simulation software can not only detect Springback early on, it can also compensate for it. This paper gives the prediction of Springback for an automotive component named Bracket Shock Absorber mounting used in automotives. In this research the material properties for E 34 are used. Sheet metal with different thicknesses such as 5, 4 and 3 mm are used. Also different die radius such as 5, 4 and 3 mm are used. The effects of these parameters on sheet metal are studied and Springback is investigated.
