Abstract

The machinability of the epoxy resin reinforced with multi-wall carbon nanotubes (MWCNTs) was evaluated during turning. The experiments were designed and performed using Taguchi design of experiment approach. The independent factors were the volume fraction of the MWCNTs, the cutting speed, feed rate and the depth-of-cut. The dependent (machining characteristics) factors were the surface roughness of the machined surface, the roundness error and the material removal rate (MRR). The results revealed that volume fraction of MWCNTs has slight influence on the MRR, surface roughness and roundness error of epoxy/MWCNTs nanocomposites. The cutting speed has the most significant influence on the MRR of epoxy/MWCNTs nanocomposites. While the feed rate is the most influential factor on both surface roughness and the roundness error of epoxy/MWCNTs nanocomposites
