Abstract

The surface finish of automotive components plays a vital role in market, in order to attain through effective machining. The most effective machining process is Abrasive Water Jet technology (AWJT). This study focuses on an experimental investigation into the AWJT drilling performance on austenitic steel (AISI 316L). The AWJT process involves various parameters that significantly influence machining quality. In this research, we explore the impact of abrasive pressure, traverse rate, stand-off distance and mass flowrate on the surface finish of AISI 316L steel. Our experimentation employs a full factorial design and ANOVA technique to analyze the influence of each parameter on surface roughness and material removal rate. Subsequently, we developed an empirical model for surface roughness through multilinear regression analysis. in which abrasive pressure has more influence in surface roughness by 75.03% and material removal rate by 69.38%.
