Conventional way of cooling/lubrication requires higher coolant cost, waste and disposal cost. Not only has that it had many negative impacts on environment and operators health. For attaining highest efficiency of cutting fluids with minimum quantity, different sustainable strategies are tried to develop. In recent decades researchers are worked out on different cooling/lubrication strategies alternative to conventional cooling. This paper represents a comprehensive review of all presently practiced cooling/lubrication strategies and their effects on different aspects such as surface quality of machined component, tool wear, tool life, cutting temperature, cutting forces etc. through analyzing selected papers. The influence of different cutting fluids such as solid lubricants, nanofluids, ionic liquids etc. with their positive and negative impacts is also discussed. The research gaps are also identified for further research works. From review it is clear that the machining performance is highly affected by cooling techniques and coolant types. Selection of proper cooling technique with suitable cutting fluids depends on work material, tool material and cutting variables.

I also acknowledge the help rendered by the Director, DAERS, BUET who provided machine shop and welding & foundry shop facilities whenever required. I would like to express my heartfelt gratitude to all the staff members of Central Machine Shop and Machine Tools Lab who have helped a lot whenever required, especially M. A. Wahab, M.

In recent decades researchers are highly motivated to use Nanofluids as a novel cutting fluids due to its some attractive properties such as high thermal conductivity, better wetting and spreading ability, suitable rheological properties with changing nanoparticles size, shape and mixing contribution. It has already been reported by many researchers that the main challenge of applying Minimum quantity lubrication (MQL) in machining processes is its lower cooling effect which has already been reduced remarkably by using nanoparticles as additives in base oils and this paper is an effort of authors to represent the successful implications of Nano-fluids assisted MQL in different mac...
