Abstract

Aluminum alloy are widely adopted material for engineering applications in automobile, aircraft and marine industries. Its high strength to weight ratio attracts modern industry to extend its applications in various domains. For producing various components, turning is the most reputed machining operation. The method of manufacturing directly impacts the product accuracy. The present research deals with fabrication and optimization study in dry turning of LM25 Aluminium Metal Matrix Composites (AMMCs). For AMMC fabrication, 10 wt.% of micro and nano Al2O3 ceramic particle is added as reinforcement. Hybrid Grey Relational Analysis (GRA) coupled Principal Component Analysis (PCA) technique is suggested for finding optimization results. Experiment was conducted with cutting speed (V), feed rate (f), and depth of cut(d) as input parameters. Based on optimization, feed rate dominates the entire turning process compared to cutting speed and depth of cut and 12.95% improvement of GRA was achieved at the end of confirmation experiment
