To Analyze and Study CNC Lathe in Turning Machining Parameters

Abstract

Metal matrix composites (MMCs) consists an important class of design which have weight-efficient structural materials that are inspiring every field of engineering applications. There has been an increasing interest in composites containing low density and low-cost reinforcements. Among various discontinuously dispersed solids used, alumina is one of the most inexpensive and low-density reinforcement available in large quantities as solid waste by-product during combustion of coal in thermal power plants. Hence, composites with Alumina as reinforcement are likely to overcome the cost barrier for wide spread applications in automotive and small engine applications. To produce Al matrix cast particle composites, wet ability of the ceramic particles by liquid Al is essential. To improve wet ability, elements such as Alumina are added into Al melt to incorporate the ceramic particles. The present work has been focused on the utilization of abundant available industrial waste. Alumina in useful manner by dispersing it into Alumina matrix to produced composites by mechanical stir casting. Wide size range (0.1–100 μm) Alumina particles were used. The mechanical properties such as hardness and tensile strength, Toughness, and microstructure have been investigated. The experimental investigation of hybrid metal matrix composites with aluminum and alumina reinforced aluminum alloy (Al 6064) composites samples 5%, 10%, 15%, 20%, 25% and 30% volume fraction applied for the purpose of fabrication and testing of the materials. Also, the machining parameters of CNC lathe in turning namely the speed, feed, depth of cut and nose radius are optimized by using response surface methodology.
