This paper presents the detailed experimental investigation on turning Aluminium Silicon Carbide particulate Metal Matrix Composite (Al-SiC –MMC) using polycrystalline diamond (PCD) 1600 grade insert. Experiments were carried out on medium duty lathe. A plan of experiments, based on the techniques of Taguchi, was performed. Analysis of variance (ANOVA) is used to investigate the machining characteristics of MMC (A356/10/SiCP). The objective was to establish a correlation between cutting speed, feed and depth of cut to the specific power and surface finish on the work piece. The optimum machining parameters were obtained by Grey relational analysis. Finally, confirmation test was performed to make a comparison between the experimental results and developed model and also tool wear analysis is studied.

Natural fiber reinforced composite has been the topic of recent studies and is preferred in various fields of engineering for the specific properties and bio-friendly nature. Surface modification of the natural fibers has been recommended to achieve good bonding. The performance of fiber reinforced polymer composites has been enhanced by the addition of nanofillers. The present work investigates the effect of surface modification of fibers by alkali treatment and the surface roughness and drilling forces in jute fiber reinforced nano-phased epoxy composite are also studied by changing the content of graphene. Graphene has enhanced the quality of hole in nanocomposites.
