Abstract

Cutting fluids are commonly used for cooling and lubrication in machining but are unsafe to the environment and cause health problems in workers. Though dry machining can be used to eliminate this problem, it is not preferred, owing to high temperature and friction. Additives with higher thermal conductivity and lubricating properties can increase the cooling and lubricating capabilities of cutting tools. Present work aims to check the feasibility of preparing graphene self-lubricated tungsten carbide tools using powder metallurgy and adding varying concentration of graphene. The prepared tool materials are tested for tribological and thermal properties. Both Inconel718 and Ti6Al4V are machined using graphene self-lubricated tools. Addition of graphene in minute quantities to tungsten carbide tools enhanced the tribological and thermal properties and also showed improvement in turning performance.
