Experimental Investigation and Optimization of SiC Abrasive Water Jet Machining of Aluminium Alloys

Investigation of the parameters variation over the abrasive water jet machining of aluminium 2014 alloy was studied using the Taguchi technique. Traverse speed, standoff distance, pressure and mass flow rate were considered as the process parameters and were varied at three levels. The depth of cut was taken as the response, and it was measured and analysed statistically. The optimal parameters to achieve the maximum depth of cut were identified with the main effect plot. Most influencing parameters over the depth of cut were identified with the analysis of variance and response table. A mathematical relationship was developed to predict the depth of cut.
