Abstract

In this research paper, the effect of abrasive water jet (AWJ) machining process parameters such as jet operating pressure, feed rate, abrasive concentration and standoff distance (SOD) on the surface roughness produced during machining of graphite mixed glass fibre reinforced polymer (GFRP) composite is investigated. Experiments were conducted using Taguchi's L27 orthogonal array design and the process parameters were optimised to obtain high surface finish. Experimental data were analysed using analysis of variance (ANOVA) which shows that the surface roughness decreased by 15.90% and increased by 9.22% for the increase in operating pressure and SOD respectively. Also, regression model is developed to predict the surface roughness and found that the predicted values are in close agreement with the experimental values (error 6.57%).
