Abstract

The aerospace, biomedical engineering, and military industries have recently relied on titanium alloys due to their exceptional strength to weight ratio and corrosion resistance. However, titanium alloys are known to be challenging to machine due to their low thermal conductivity, high hardness, and tendency to chemically react with all tool materials at high temperatures. To overcome this issue, the use of cutting fluid has an important role in reducing the high temperature and friction that occurs in machining processes. However, excessive or incorrect use of cutting fluids has adverse effects on human health and the environment. Therefore, The Minimum Quantity Lubrication (MQL) technique has gained significant interest in machining processes to reduce the environmental impact caused using traditional cutting fluids. Recently, nanofluids have become increasingly utilized in the mechanical engineering field due to their superior lubrication and heat dissipation capabilities. The objective of this study is to enhance the surface roughness using cutting fluid with added nanoparticles during the turning process of Ti-6Al-4V alloy. Several factors such as chip formation, tool degradation, and surface characteristics were examined at varying cutting speeds, feed rates, cutting conditions, and nanoparticle concentrations.
