Application of Taguchi method for identifying optimum specific energy consumption in CNC face milling

In the present study, the effect and optimization of three cutting parameters, namely depth of cut, cutting speed and feed rate on the specific energy consumption in the face milling was investigated by using the Taguchi method. Experiments were carried out in dry condition as per Taguchi's L9 orthogonal array. The cutting parameters were optimized using signal-to-noise ratio, whereas analysis of variance was employed to determine the significance of the process parameters influencing the specific energy consumption. The results revealed that feed rate and depth of cut are the most significant parameters affecting specific energy consumption. The confirmation test is conducted at optimum cutting conditions and it is found that the Taguchi method was notably successful in the optimization.
