Optimizing the Cutting Parameters to Improve the Surface Roughness in Hard Turning of SKD11 Steel Machining using the Taguchi Method

Author(s): Hoang-Anh Truong


Surface roughness is a crucial parameter for evaluating the quality of metal cutting processes. In this study, the Taguchi method is employed to identify the optimal machining parameters to achieve the minimum surface roughness in machining hard steel SKD11. Three fundamental parameters of the cutting regime are selected: Cutting speed, cutting depth, and feed rate. Each parameter is divided into three levels: Low, medium, and high. The experimental design is constructed based on the L9 array of the Taguchi method. The results indicate that the feed rate has the greatest influence on machining surface roughness, followed by cutting depth and cutting speed, respectively. An optimal cutting regime is proposed to achieve the minimum surface roughness.
