Abstract: The present work deals with the turning of aluminium and silicon carbide nanoparticle nanocomposite material. It deals with the uniform distribution of silicon carbide nanoparticles (25 nm) with aluminium metal powder. The reinforcement SiC_p is used with weight % of 1, 1.5 and 2. Initially, a compression test has been conducted on Al-SiC_p nanocomposite to study its mechanical properties. The optical microscopy and transmission electron microscopy (TEM) of Al-SiC_p workpiece has been conducted. Further, the experiment was conducted using Taguchi L₁₆ orthogonal array at three different factors and four different levels for machining of Al-SiC_p workpiece. The response parameters i.e., flank wear (VBc) of cutting insert and surface roughness (Ra) of work material have been optimised by principal component analysis (PCA). Analysis of variance reveals the most influencing parameters during machining are cutting speed and depth of cut for flank wear and depth of cut and feed for surface roughness.

Keywords: aluminium; composite; surface roughness; Taguchi; flank wear; cutting speed; depth of cut.
