Cutting forces, friction coefficient and surface roughness in machining Ti-5Al-4V-0.6Mo-0.4Fe using carbide tool K313 under low pressure liquid nitrogen

This work presents a study on the effect of low pressure cryogenic liquid nitrogen on cutting forces, friction coefficient, surface roughness of the machined surface and tool wear under high speed machining of a relatively new titanium alloy, Ti-5Al-4V-0.6Mo-0.4Fe. The experiments were conducted in dry and cryogenic conditions. The experimental results show that liquid nitrogen can reduce the friction force, friction coefficient and improve the surface roughness.
