Determination of optimal cutting parameters to improve surface roughness based on different optimization approaches

Determination of optimal machining parameters by using optimization techniques is continuous engineering task with the main aim to reduce the production cost and achieve desired product quality. Hence, this paper presents different optimization approaches to determine optimal values of cutting speed, feed and depth of cut with the purpose of improving the surface roughness obtained in turning operation. To achieve this, two experimental plans have been carried out based on the factorial design of experiments and the orthogonal arrays. By using these plans, the classical mathematical optimization was performed according to response model of the surface roughness as well as the Taguchi approach. Furthermore, the experimental verification of optimal cutting parameters with their influences on the surface roughness was done. Finally, the results of optimal turning parameters obtained with different optimization approaches were compared.
