Abstract :Ecological and eco-friendly cooling/lubrication methods have an important place in the sustainable manufacturing process. The hazards of the conventional cooling can be minimized, and it can be contributed the manufacturing performance, thanks to these ecological systems. In this study, the machinability of AISI 316L stainless steel under ecological cooling/lubrication methods was investigated. The face milling operation was applied to AISI 316L stainless steel for machinability examination under three different cooling cooling/lubricating conditions insert ignore into journalissuearticles values(minimum quantity lubrication-MQL, LN2 and MQL+LN2);, three different cutting speeds insert ignore into journalissuearticles values(120, 150 and 180 m/min);, constant feed rate insert ignore into journalissuearticles values(0.1 mm/rev); and a constant cutting depth insert ignore into journalissuearticles values(0.5 mm);. The average surface roughness insert ignore into journalissuearticles values(Ra-µm);, maximum cutting temperature insert ignore into journalissuearticles values(T-°C);, and tool wear insert ignore into journalissuearticles values(VBmax-mm); were selected as machinability performance criteria. At the end of experiments, the lowest value of the maximum cutting temperature insert ignore into journalissuearticles values(101.1 °C); was obtained at 120 m/min cutting speed under LN2 cutting condition. The lowest value of surface roughness insert ignore into journalissuearticles values(0.237 µm); was obtained at 150 m/min cutting speed under MQL+LN2 cutting condition. When the experimental results were evaluated in general, it was understood that the MQL+LN2 hybrid cutting condition provided significant improvements in all cutting parameters compared to other cutting conditions.
