Performance Evaluation of Abrasive Water Jet Machining on AA6061-B4C-HBN Hybrid Composites Using Taguchi Methodology
Aluminum Metal Matrix Composites (AMMCs) have received considerable attention due to their high strength-to-weight ratio, low cost, and high wear resistance that are appropriate for automotive and aerospace applications. Stir casting technique has been attempted to fabricate AMMC using boron carbide (B4C) as hard reinforcement and hexagonal boron nitride (hBN) as the solid lubricant by varying volume (5, 10, and 15%) method. Experimental investigation on machining of hybrid composites to study the effect of Abrasive Water Jet Machining (AWJM) parameters such as mesh size, abrasive flow rate, pressure, traverse speed, and % of reinforcement on Kerf Taper Angle (KTA) and Surface Roughness (Ra) was carried out. Taguchi’s L27 Orthogonal Array (OA) and Analysis of Variance (ANOVA) have been used to determine the significant parameters affecting the responses and results were validated using Pareto analysis.
