Sheet metal forming is a process where pieces of sheet metal are modified to their geometry rather than removing any materials. Major problems in sheet metal forming operations are the spring back effect and the deformation errors. Spring back is a very complicated behaviour and is not easy to predict through the mathematical models. It can only be controlled and minimised but quite difficult to be eliminated. Different types of materials used for sheet metal forming are aluminium and mild steel for its deformation capabilities and other properties. In this work, an experimental investigation of spring back of aluminium and stainless-steel sheets with two different thicknesses is carried out using V bending machine under dry and wet environment. The grid analysis method will be used for stress-strain deformation analysis and a stress vs strain graph will be plotted. A Taguchi based optimization technique is carried out to find optimum parameter combination and analysis of variance (ANOVA) to find the most significant factor. [ABSTRACT FROM AUTHOR]
