Effect of Cooling/Lubrication Using Cooled Air, MQL + Cooled Air, N₂ and CO₂ Gases on Tool Life and Surface Finish in Machining – A Review

Abstract:

Advanced materials like nickel and titanium have unique combinations such as low thermal conductivity, high chemical reactivity, and high hardness. Machining these materials requires suitable lubricant and proper cooling technique for increasing tool life, decreasing cutting temperature, and improving surface roughness. This paper presents a brief review done on gas-based coolant-lubricants (CLs) used in the form of either gas or cooled-pressured air and gases. Main gas-based CLs are air, N₂, and CO₂. Investigations of previous researches include hypered cooled air (at different cooling temperatures), minimum quantity lubrication (MQL), and gases which have been used on machining operation that affect tool life and surface finish. Compresed N₂ and cooled air with MQL was identified as the most suitable coolant-lubricants for machining performance. Furthermore, this type of gas-based coolant-lubricant (CLs) is considered as one of the environmentally conscious machining.
