Abstract

Abstract: Epoxy resin finds its application in various sectors like marine, automotive, aerospace, construction and structures due to better thermal stability and mechanical properties. Addition of graphene into epoxy improves the chemical and physical properties at small loading condition which depends on the dispersion of graphene into epoxy. In the present investigation, end milling operation is executed on graphene/epoxy nanocomposite by varying the parameters like spindle speed (500–1500 rpm), feed rate (50–100 mm/min) and weight % of graphene (0.0–0.2) to investigate and optimize the surface roughness by using statistical analysis. Results show that weight % of graphene is the dominating factor followed by spindle speed and feed rate. Surface roughness decreases with increase in spindle speed and weight % of graphene while increases with increase in feed rate.
