Roughness modeling in up-face milling

In this study, we aimed to optimize cutting parameters to minimize surface roughness in up-face milling. An experimental system method has been used to analyze the evolution of surface roughness in connection with cutting parameters, and to develop mathematical models for roughness and optimal cutting parameter calculation. Roughness results show that lower cutting speeds give poor surface quality. This is due to the formation of a built-up edge. On the other hand, higher cutting speeds result in more roughness due to vibrations. So, an optimal value of cutting speed must be used to minimize roughness. We found good correlation in experimental values of roughness .
