Bent parts with high accuracy are required in daily life applications. While bending generally metal sheets, polymers or laminate sheet materials are used. In this study particular focus is on Aluminium grade material Al-5251 H24 having application in marine structures, aircraft parts, etc. by conducting test in V-bending die as it is economical and variation due to different factors can be studied easily. Spring back in simple terms means elastic recovery of the material. Every material has its own elastic properties, due to which it will exhibit spring-back or spring-go effect after unloading the tool force. In research study of spring back it is found that spring-back is affected by material properties, tool geometry and process parameters etc. With the help of Taguchi approach to minimize the no. of experiments by using Orthogonal Array and ANOVA technique to determine spring back affecting parameters and thus optimize it, also the focus is to determine the most affecting parameters.
