Abstract :

This paper focuses on investigation of design process parameters which mainly affect the Springback. Elastic Modulus is considered as the factor related to material and bending angle, punch radius and material thickness are considered as the factors related to the V bending process. The results of experiments for varying elastic modulus at different plastic strains were regressed and the regression equation gave the relationship between elastic modulus and plastic strain which can be used for more accurate prediction of Springback. The further experiments were conducted for V bending to find the effect of critical process parameters on Springback for aluminium (HE 9). The percentage contribution of each parameter causing springback was calculated. The material thickness was found as the most significant parameter causing springback in aluminium (HE9). Hence in order to minimize the Springback in aluminium (HE9), material thickness needs to be effectively controlled. The confirmation experiments were conducted for validation. The results of the confirmation experiments were found to be within the confidence interval.
