Abstract—In this paper there is comparative study of the cutting temperature mechanism of turning of Ti-6Al-4V with graphene oxide (GO) nanofluids and conventional fluids (CC). The influence of machining parameters, such as cutting speed, feed rate, cutting depth, coolant pressure and coolant concentrations were investigated when turning with polycrystalline diamond (PCD20) insert. The Transmission electron microscopies (TEM) of graphene oxide nanoparticles have been investigated and the thermocouple applied in measurement with cutting temperature in too-chip interface. The cutting temperature was reduced up to 15.13 ℃ when lower velocity, lower feed and higher coolant pressure applied. In the meantime, the cutting temperature decreased by 48.66 ℃ when GO nanofluids applied.
Index Terms—Ti-6Al-4V, graphene oxide, nanofluids, PCD, turning.
