Taguchi optimization methodology was applied to optimize cutting parameters in end milling operation. Machining carbon steel AISI 1060 with high speed steel tool under finishing conditions with coolant is used in this study. The experimental work has been conducted on CNC milling machine tool, and the experiments carried out by using orthogonal array as suggested by Taguchi. The milling parameters are cutting speed, feed rate, depth of cut and cutting tools with different number of flutes were used as additional factor in cutting conditions. An orthogonal array, signal-to-noise (S/N) ratio is employed to analyze the effect of these milling parameters on surface roughness.
The results show that the optimum parameters of machining is obtained at a depth of cut 0.3 mm, cutting speed 1000 rpm, feed rate 50 mm/rev and number of flutes four. Confirmation tests with the optimal levels of cutting parameters are carried out in order to illustrate the effectiveness of Taguchi optimization method. Taguchi method has been found very efficient tool to obtain an optimum surface roughness or by other meaning a smaller surface roughness.
