Abstract

Abstract: Abrasive Water Jet (AWJ) cutting is one of the prominent technologies for processing wide variety of materials ranging from ductile to brittle, hard to soft and thin to thick materials. AWJ cutting has many advantages of no-thermal distortion, frictionless cutting and requires small cutting forces. In the present study experimental investigations were made to find out the depth of cut of AZ91 magnesium alloy. New approach of finding depth of cut using profile projector has been used in this study. The effect of process parameters on depth of cut was investigated through Taguchi experimental design of L9 orthogonal array. Analysis of Variance (ANOVA) was employed to investigate the influence of process parameters on depth of cut. Results have shown depth of cut increased with increasing water pressure and decreased with increasing traverse speed. Contribution of Water Jet pressure found more to depth of cut and also this study concludes that AWJ cutting is the most viable and effective alternative for machining magnesium and its alloys.
