AbstractIn this paper, Taguchi technique is selected in order to explore ideal process parameters for abrasive water jet machining (AWJM). The goal of this exploratory research is to explore the effects of machining parameters on MRR and SR of a work piece made of aluminum a356 alloy. Our approach is based on Taguchi's technique, ANOVA and the SN ratio in order to optimize AWJ machining process parameters for successful machining and to establish optimal values of each AWJM parameter, namely, abrasive stream rate, traverse speed, standoff distance and abrasive grit size. L9 orthogonal array is utilized for varying values of A, B, C, D and three tests were conducted for each combination. Using the SN ratio, it was possible to find the optimal parameter values for AWJM. It was concluded that, in actual practice, the ideal combination of AWJM process parameters fulfill the requirements for machining of cast A 356 aluminum alloy.
