Parametric Optimization of Abrasive Water Jet Machining of Inconel
Abstract Abrasive water jet machine (AWJM) is a nonconventional machining technique in which, material removal takes place from the work piece by impact erosion high pressure and high velocity water jet mixed with abrasive material to provide smooth surface finish. Experiments are conducted to study the influence of various process parameters of abrasive water jet machining on Material removal rate (MRR) and Surface roughness (Ra) of Inconel718. Experiments are carried out using L9 Orthogonal array by varying Water Pressure (WP) traverse speed (TR) abrasive flow rate (AFR) and stand of distance (SOD) for Inconel 718 material. In the present paper an attempt has been made to optimize the AWJM process parameters of Inconel 718 using Taguchi method.
