Abstract

Sustainability specifically addresses using ecological cooling/lubrication techniques in the manufacturing industry. Dry, MQL, CO2, LN2, N2, CO2 +MQL, LN2 +MQL, and N2 +MQL techniques were preferred for ecological cooling/lubrication. To determine the effects of cooling/lubrication techniques on machining performance, cutting speed (Vc 80 m/min), feedrate (f 0.12 mm/rev), and cutting depth (ap 0.5 mm) were taken as constants. Cutting tool wear and mechanisms, surface roughness and topography, cutting temperature, and vibration peak values are preferred as machining performance characteristics. At the end of the turning experiments performed with sustainable cooling/lubrication techniques: N2 +MQL hybrid cooling/lubrication technique performed better performance in cutting tool wear (0.226 mm), surface roughness (1.658 & mu;m), and vibration (48.017 m/ sec2), while LN2 cooling technique showed the best performance (87 degrees C) in cutting temperature. Compared to dry condition, the N2 +MQL hybrid cooling/lubrication technique reduced tool wear, surface roughness, and vibration by 73.50%, 53.9%, and 42.4%, respectively.
