Abstract

Recently, titanium has been used for many areas such as aircraft turbine blade, fuel tanks , marine hardware and surgical implant. Titanium alloy T i- 6A 1-4 V is one of the materials that difficult to machine due to its hardness. The conventional method will lead to rough surface roughness, high cutting force and the tool life is shorter. The aim of this study is to investigate the effect of different concentration of hexagonal boron nitride (hBn) nanofluid on the surface roughness , tool wear and cutting force of titanium alloy using milling process. In this research, four different concentrations of hBn nanofluid were used which are 0.00 wt%, 0.02 wt%, 0.06 wt% and 0.1 wt% and the milling performance between conventional cutting fluid (0.00 wt%) and nanofluid were compared. HBn nanofluid was prepared by mixing the hBn with deionized water and PVP K30 as a surfactant. The other parameters such feed rate, cutting speed and depth of cut were remained constant. The used .of hBn nanofluid cause lower surface roughness, lower, cutting force and lower tool wear during the milling of titanium alloy
