Machinability optimization of abrasive water jet cutting process on AA6082 aluminium alloy

Abstract

Aluminium alloys are extensively used nowadays in various manufacturing industries due to its special properties and high strength. In this study, AA6082 aluminium alloy is taken into consideration by studying the machinability properties using the abrasive water jet cutting process. RSM technique is used for conducting the experiments by varying the input factors such as stand-off distance, abrasive feed and nozzle transverse speed. The effect of hardness and surface roughness is investigated. The correlation between the input parameters and the corresponding output was tested by analysis of variance to check the 95% confidence level.
