Process parametric optimization of Impact test using Taguchi and ANOVA approach

ABSTRACT Impact testing methodology is finding the applications for determining the impact strength of the different materials. The process implies hammering effect on the work material that determines how much mechanical energy required for failure of any material. The aim of this research work is focused on the optimization of process parameters in order to maximize the impact toughness using taguchi technique. The research work investigates the effect of process parameters on impact values. An L9 orthogonal array was chosen for the design of experiment. The optimum process parameters were determined by using signal-to-noise ratio. The levels of importance of process parameters on impact testing were obtained using analysis of variance. The variation of impact properties with process parameters were mathematically modelled using the regression analysis. The results obtained using design of experiments were validated analytically and graphically shows that work material affected the impact toughness most significantly factor of Izod impact value. The material and height of the hammer are the most significant factor of Charpy impact value.
