A Study of Optimal Factor in Milling Process of Aluminum AA6061 by Taguchi method

Abstract

This research aims to study parameter that have an influence in the surface roughness of Aluminum AA6061 milling process. Three factor; cutting speed (Vc), depth of cut (D), and feed rate (F) which have 3 levels for each factor have been defined by taguchi method. The experimental results have been calculated the S/N ratio for selecting the Max signal-to noise ratio. Next, to predict and variance analyzing is operated for the experimental validity testing. From the study, Factor that have an influence to the surface roughness are cutting speed and feed rate. The results from taguchi method suggest to select cutting speed, depth of cut and feed rate at 130 m/min, 2 mm and 150 mm/min, respectively.
