Optimizing the Factors of Abrasive Water Jet Machining for Reinforced Al7075 Material Matrix Composite

Abstract

This study investigates the enhancement of productivity in the aerospace industry through the optimized machining of Al7075-based Metal Matrix Composites (MMCs) reinforced with TiO2, ZnO, B4C, MgO, and B4N. Utilizing a Taguchi-based Multi-objective Response Surface Methodology (MORSM), the research identifies optimized parameters for Abrasive Water Jet Machining (AWJM) of these MMCs. A systematic experiment design using the Taguchi method allows for the variation of parameters, while contour-plot analysis facilitates data examination. The MORSM approach identifies machining parameters that significantly improve the Material Removal Rate (MRR). Validation experiments confirm the practical applicability and accuracy of the optimized parameters by comparing experimental and simulated results. This study highlights efficient machining parameters for various reinforcements in Al7075-based MMCs, demonstrating the method's reliability and utility in advancing aerospace material machining, thereby contributing to superior productivity and performance in aerospace application.
