Effect of abrasive water jet turning parameters on depth of cut of AISI 1050 steel

Abstract

This study analyzes the depth of cut as an output of experiments using abrasive water jet turning (AWJT) on AISI 1050 steel material and machining parameters were optimized using Taguchi method. Three different nozzle feed rates (0.01, 0.017 and 0.09 mm/min), abrasive mass flow rates (50, 200 and 350 g/min), lathe spin rates (500, 1500 and 2500 rpm), nozzle distances (2,10 and 18 mm) and two different nozzle diameters (0.75 and 1.3 mm) were used as machining parameter values. Taguchi's LI8 orthogonal array was adopted for the test design. The impact of parameters on depth of cut was statistically examined using analysis of variance and S/N ratios obtained. As a result of the tests, Nozzle feed rate proved to have the highest impact on the depth of cut with its rate of 75.38%. Using a 0.75 mm nozzle diameter led to decreased depth of cut. Increasing the spindle speed proved to increase the depth of cut.
