Abstract

This paper presents a machinability evaluation of Inconel 718 material when using a new uniform-temperature indirect cooling method that incorporates constant-pressure liquid nitrogen (LN2). The flank wear of a TiAlN coated tool used with this indirect cooling system was much lower than that of the tool used with dry machining under all machining conditions. Also, the surface roughness resulting from machining with this indirect method was far less than that of a dry machined surface after the same cutting time. Reduced heat generation and uniform temperature in turning operations play important roles in tool life and surface quality.
