Abstract

In this research, Ti-6Al-4V was machined under dry cutting conditions and cryogenic cooling environment, on cutting tool and workpiece material, surface performance, and cutting force were studied. However, all cases observed a positive influence of cryogenic machining on selected aspects after turning Ti-6Al-4V. Turning process is carried out for five different cutting speeds (35, 40, 55, 70, 80 m/min) while 0.15 mm/rev cutting feed out and 0.5 mm cutting depth are to be constant. It was found that Cryogenic cooling can decrease cutting temperatures, increase tool life, improve the roughness of the cutting surface and the residual stress of the surface, improve the wear resistance and corrosion resistance of the cutting surface.
