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.

Advanced materials like nickel and titanium have unique combinations such as low thermal conductivity, high chemical reactivity and hardness. All of these properties are desirable to be used as suitable lubricant and proper cooling technique for increasing tool life, decreasing cutting temperature and improving surface roughness. This paper presents a literature review done on gas-based coolant-lubricants (CLs) which used in the form either gas or cooled-pressured gases. Investigation of previous researches with different approaches which have been used on machining operation that effect on cutting temperature, tool wear and surface roughness. As a result, gas-based coolant-lubricants (CLs) has been determined as one of the most suitable cooling process for machining cutting operation in terms of improvement in tool life and surface roughness. Furthermore, this type of cooling process is considered as one of environmentally conscious machining.
