About the Possibility to Assess Cutting Fluids Efficiency Using an Instrumented Tribological Approach

During a machining operation, the tool tip is subjected to elevated interface temperatures and contact pressures. A considerable improvement can be achieved through an appropriate selection and application of a cutting fluid. Although many technologies attempt to reduce their use to move to a cleaner production, they are still widely employed in industry. Under such severe conditions, it is necessary to understand their exact contribution from a tribological point of view in order to optimize their use. The aim of this study is to evaluate the ability of a fluid to penetrate and remain at the tool-material interface.
