International audience; As mechanical, physical, and microstructural properties of metals can be significantly affected by the machining process, electrochemical properties and corrosion resistance are consequently altered. Manufacturers should control the impact of cutting conditions on surface integrity, as it will affect the component’s functional performance and life. This study addresses the case of orthogonal cutting of oxygen-free high conductivity (OFHC) copper. A set of experiments was performed and a statistical analysis was conducted to reveal the relationship between the cutting conditions and the surface integrity in terms of residualstresses, microstructure, plastic deformation and hardness, and the impact of those parameters on the electrochemical behavior. The physical origins of the observed phenomena are explained. The results show that the surface performance can be controlled by selecting the appropriate cutting conditions (e.g., reducing the tensile residual stress and roughness by more than 75%), suchthat the electrochemical behavior can be enhanced.
