The application of cold air and nano-mql as cooling strategy in high speed milling of titanium alloy ti-6al-4v: a review

Abstract

Ti-6Al-4V is the most popular type of titanium alloy having a combination of high strength to weight ratio, light weight, high strength at elevated temperature, good corrosion resistance, and good biocompatibility properties. Aerospace, automotive, oil and gas, and biomedical industries, all gained benefits from this material due to its inherent properties. However, Ti-6Al-4V is considered as hard to machine material and is known for its poor machinability mostly due to its own good combination of properties. This has attracted interest in many researchers to study the outcome of different machining conditions and environments on the machining performance of Ti-6Al-4V. A lot of efforts has been put to increase the productivity in machining Ti-6Al-4V by exploring the possibility of high speed machining and the effects of various cooling strategy. This paper presents a review on the application of cold air and nano MQL as one of the cooling strategies in high speed milling of Ti-6Al-4V.
