The quality of working surfaces plays an important role in automotive industrial components. One of the main characteristics of such surfaces is their wear resistance. In this study external cylindrical surfaces were analyzed. A Design of Experiment methodology was applied and hard turning experiments were carried out to analyze the effects of the cutting parameters on the 3D surface roughness values of reduced peak height, skewness and kurtosis. The study confirmed earlier findings that at lower feed the wear resistance is higher based on the analyzed roughness parameters. The cutting speed and the depth-of-cut do not influence these parameter values significantly.
