“…Applying CO 2 flow in liquid form is another technique of cryogenic cooling. Murugappan et al [111] implemented precooling cryogenic using dry ice and two different types cutting inserts in turning Al 6063. The experimental results showed that insert type and cooling techniques have influential effect on productivity and product quality.…”

Various types cooling/lubrication techniques are used in machining processes for enhancing machining performances. 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.

Cutting parameters have a significant influence on the surface finish after turning, which can generate unwanted surface roughness. Thus, the parameters optimization could be a favorable strategy to improve the machined part quality. Therefore, the optimization of the cutting speed (v c), feed rate (f) and depth of cut (a p) on finish turning of 6082-T6 aluminum alloy using an uncoated carbide tool (positive rake angles and 0.4 mm tip radius) under dry and reduced quantity lubricant (RQL) conditions was performed. The input variables were combined and randomized via Box-Behnken design of experiments. The surface roughness profiles were recorded, and the roughness parameters R a and R z were measured in each combination of parameters. After optimization, the best results of R a (0.44 μm) and R z (2.73 μm) after dry machining were obtained with v c = 851 m/min, f = 0.07 mm/rev. and a p = 2 mm. Since RQL machining, the correspondent levels (v c = 403 m/min, f = 0.05 mm/rev., a p = 0.5 mm) resulted in the lowest values of R a (0.18 μm) and R z (0.96 μm). The RQL favored the chip formation in turning of AA6082-T6, minimized the occurrence of grooves (scratches), burrs and waviness on the machined surface and generated better surface quality.
