In this paper experimental investigation is carried to study the effect of parameters, viz water pressure, Traverse speed, and Standoff distance, of Abrasive Waterjet Machine (AWJM) for mild steel (MS) on surface roughness (SR).Further Taguchi’s method, analysis of variance and signal to noise ratio (SN Ratio) are used to optimize the considered parameters of abrasive Water Jet Machining. In Taghuchi’s design of experimentation, L9 orthogonal array is formulated and it can be concluded that water pressure and transverse speed are the most significant parameters and standoff distance is sub significant parameter.

Keywords: Waterjet machining, MS, Taguchi, Anova, S/N ratio, surface roughness.
