Optimization of End Milling Parameters on Surface Roughness of Die Steel HCHCr by Taguchi Method

- This paper outlines the Taguchi Optimization methodology, which is applied to optimize cutting parameters in end milling when machining Die steel (HCHCr D3). The milling parameters evaluated are cutting speed, feed rate and Depth of cut. An orthogonal Array, signal-to-noise (S/N) ratio and analysis of variance (ANOVA) are employed to analyze the effect of experiment (DOE), Mathematical model is generated by regression analysis. . Finally effect of process parameter on surface roughness (Ra) in end milling studied and optimum solution is carried out. The study shows that the taguchi method is suitable to solve the surface quality problem with minimum number of trials.
