Abstract

Surface roughness prediction in side milling of high density polyethylene and rubberwood flour composites was designed by Box-Behnken and analyzed using Response Surface Methodology. Factors in this study are speed, feed rate, and depth of cut. From the experiment, it was found that all of the factors affected on the surface roughness properties. The result of optimal condition analysis with the factors on side milling of composites found that the optimal condition was 1,000 rpm speed, 315 mm/min feed rate, and 1.0 mm depth of cut. This condition generates the surface roughness of 2.865 µm with desirability score 100%. Additionally, the real test value and the predicted response were compared to verify the accuracy of the mathematical model of the regression model. The result shows that the bias of those methods is 1.95% in which is within acceptable criteria. It was found that the optimal condition in side milling of composites obtained from the mathematical model were reliable. It is optimal for use in predicting surface roughness in composites
