摘要

This paper investigated experimentally the machining of Ti-6A-4V with a new graphene based cutting fluid. Three different types of graphene oxide (GO) nanofluids with various GO concentrations were applied in a series of cutting experiments. Tool wear, cutting force and the vibration in turning titanium alloy with the new nanofluids as well as conventional coolant were analysed. The working mechanism and different cutting effects caused by the variation of GO concentration and coolant pressure were discussed. The results show that the cutting force was reduced by 50.83 % when GO nanofluids were used. The vibration in the turning Ti-6Al-4 V with GO nanofluids was significantly lower than that in using base fluids. While the Build-up-Edge (BUE) and adhered layers on the rake face were less than those formed in using conventional coolant, the reduction of flank wear was up to 44.1 %, 53.9 % and 71.3 % respectively when GO nanofluids with the concentration of 0.1 wt.% GO, 0.3 wt.% GO and 0.5 wt.% GO were applied.
