Study on Cutting Parameters to Reduce the Surface Roughness in Hard Turning of SKD 61 Steel using Taguchi Method

In this article, the Taguchi method was used to optimize cutting parameters to achieve minimum roughness during hard turning of SKD 61 steel. Cutting parameters selected include cutting speed, feedrate, and depth of cut. Experiments were organized by the use of L9 orthogonal array. The influence of each factor on the output response is analyzed by Minitab software. Signal to noise and analysis of variance are applied to statistical analysis. The result indicates that the feedrate has an outstanding influence compared to the other two variables. Optimal processing conditions to achieve the minimum roughness has been given. In addition, a regression equation describing the relationship between roughness and cutting parameters was built with the determination coefficient R sq of 93.99 .
