Abstract

This study shows the experimental investigation on Inconel 718 to find the parametric response of abrasive water jet cutting on top Kerf width (Wt), bottom Kerf width (Wb) and Kerf wall inclination. The machining are planned with Box Behnken Design (BBD) based on four factors at three levels each. Four important process parameters e.g P, AFR, SOD and TS, were selected in cutting. The quadratic regression models were established to forcast the Kerf quality by using response surface methodology. ANOVA has been employed to find the influence of operating factors. Result reports that traverse speed is the most influenced parameter in affecting the Kerf taper.
