This paper investigates the effect of graphene nano-platelet (GNP) content (%weight fraction) on the machinability of epoxy/GNP nanocomposites. The machinability of nanocomposites with varying loadings of GNP content was evaluated experimentally through the characterisation of cutting forces, surface morphology, chip morphology and tool wear. The minimum chip thickness phenomena of epoxy/GNP occurred at feed per tooth (FPT) between 0.2 and 0.4 μm. In order to achieve to better surface quality, the FPT should be over 0.4 µm. Epoxy/GNP with 1.0 wt% nanocomposite has produced the highest cutting force of a feed rate of ~ 3 N at 12 µm/rev. Epoxy/GNP nanocomposites exhibit the different cracking tendencies compare with plain epoxy, and the tool wear for GNP/epoxy nanocomposites is very small compared with metal nanocomposites. There is no significant difference in slot width accuracy between different types of tools, such as uncoated tool, diamond like carbon coated and diamond coated tools.
