Comparison of surface roughness at different parameters cutting speed, depth of cut or feed rate by using Taguchi Method

In the present research work gives the effect of different machining parameters (cutting speed, feed rate and depth of cut) on surface roughness in end milling is determined. Taguchi technique of optimization is used to select different parameter. The experimental work is carried out on hardened Die-Steel H-13. The processing of the job was done by solid carbide four flute end-mill tool under finishing conditions to calculate different variables and their levels. L-9 standard orthogonal array is used for calculation of number of variables and number of levels. Signal to Noise Ratio is used to calculate the significant parameter where as ANOVA F-Test is carried out to determine the percentage effect of each parameter.
