Abstract: 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 gasbased 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

Keywords: Gas-based coolant–lubricants (CLs), nickel and titanium alloys, tool wear, surface roughness and integrity, green machining.
