Optimization of Machining Parameters Using Steel En 9 Work Material in Turning Operation by Tungsten Carbide Tool Employing Taguchi Method

The present manufacturing sector is competing to increase machining efficiency and to minimize effect of environment or effect of noise factor. Steel alloys are more used in modern era of industrialization. By considering these points optimization of process parameters is done with the help of Taguchi method. This study deals with finding optimal value of process parameters (cutting speed, feed rate and depth of cut) on which minimum value of response parameters(thrust force, feed force, and radial force) can be obtained in turning operation of steel alloy EN9 by applying Taguchi method. Significant factors and percentage distribution of process parameters in affecting response parameters is investigated by ANOVA (analysis of variance). Experiments are conducted based on L9 orthogonal array. Lower the better criterion of S/N ratio is used for optimization of selected response parameters. By the study it is found that optimal level of process parameters is third level of cutting speed and first level of feed rate and depth of cut. It is found that thrust force is the significant factor in affecting response characteristics.
