Prediction and Optimization of Surface Roughness in Hard Milling of SKD61 Steel by using Taguchi Method

SKD61 steel is a type of steel widely used in the industry. In this study, the Taguchi method was used to optimize the cutting parameters to achieve the smallest surface roughness when milling SKD61 alloy steel. The three parameters of the cutting process, namely cutting speed, feed rate and depth of cut, were selected as input factors and evaluated at three levels low, medium and high. Analysis of variance ANOVA was used to analyze the influence of each input factor on the surface roughness. The results showed that the feed rate was the most influential factor on the surface roughness, followed by cutting speed and depth of cut.
