Optimization of Machining Process Parameters and Wear Analysis of Aluminum Hybrid Metal Matrix Composite
There is a growing interest worldwide in manufacturing hybrid metal matrix composites [HMMCs] which possesses combined properties of its reinforcements and exhibit improved physical, mechanical and tribological properties. Aluminum-based Metal Matrix Composites (MMCs) have received increasing attention in recent decades as engineering materials. Composite materials are known as advanced materials for their high strength, high wear resistance, good damping characteristics and their enhanced high temperature performance.The objective of the present work is to investigate the effects of the various CNC turning parameters on the machining quality and to obtain the optimal sets of process parameters so that the quality of machined parts can be optimized. Experiments are conducted on the pieces varying parameters. The work piece and cutting tool material used for machining are aluminum alloy HMMCs (Al with boron carbide and fly ash) and tungsten carbide. The process parameters considered are spindle speed, feed rate and fly ash percentage. The range of values varied are spindle speed – 2500RPM, 3000RPM and 3500RPM, feed rate –0.1,0.15 and 0.2 mm/min, fly ash –2%,4%,6%. The optimization is done by using TAGUCHI, ANOVA and ANN technique by considering L9 orthogonal array. Optimization is done using Minitab 19 software.
