Performance Analysis of Cutting Parameters on 304 Stainless Steels Using Abrasive Water Jet Technique

Abstract

One of the most challenging tasks in machining hard materials is to achieve super high precision with excellent surface finish. The reasons can be addressed due to its properties including high work hardening and poor machinability. Abrasive water jet (AWJ) machining is a multi-operational activity which is proven technology for generating high precision components. The carried-out work mainly intended to showcase the technical parameters which are prime importance in commercial and domestic applications. There parameters include water pressure, traverse speed, abrasive feed rate. These parameters were analyzed with respect to kerf taper and surface roughness on X5CrNi18-10 steel. In the present work key parameters such as traverse speed and outlet pressure were varied from 100 -200 mm /min and 100 -200 MPa, respectively. Apart from these two parameters abrasive feed rate was also varied in the range 360 -540 g/min. Our data from experimental procedures indicate that kerf taper and surface roughness were greatly deflect by variations in the three major parameters; traverse speed, water pressure, and abrasive feed rate. To ensure better comparison of work optimization of process parameter was also carried out. In this optimization response surface methodology and central composite design method was enabled. In addition, all the needed mathematical models were enabled and set of desired contour graphs for tested surface quality are systematically represented. Finally, the kerf taper angle behaviors were also carried out using ANOVA analysis powered by MINITAB 19.
