A Brief Review on Machining of Ti-6Al-4V under Different Cooling Environments

Ti-6Al-4V is an alpha beta titanium alloy which has high strength to weight ratio. It has excellent corrosion resistance, high toughness and low density, which makes is most suitable for applications in automobile, aeronautical, architectural, petro chemical and various medical equipment industries. Due to its high pressure load, high heat stress, poor thermal conductivity, varying chip thickness it is termed as hard to machine material. As it is a hard to machine material so many researchers are taking keen interest to study the effects of different machining aspects and machining environments on the machining performance of Ti-6Al-4V alloy. The present paper presents a comprehensive review on important aspects associated to machining of Ti-6Al-4V alloy using different cooling environments and machining tools. Experimental and theoretical observations for tool wear, surface roughness, machining force, tool life and machining temperature using different types of cutting inserts under distinguish cooling environments are also been discussed.
