The Effect of Hard Milling on Surface Finish of Medium Carbon Steel

Abstract

This research was to study the effect of hard milling on the surface finish of medium carbon steel. The sample specimen was selected to AISI 1050. The vertical milling process was chosen to experiment, which used insert PVD carbide tool. The experiment was applied on factors: cutting speed, depth of cut and feed rate and they were consisted of three levels. The factorial design on 33 experiments was applied. The surface roughness average (Ra) was indicated for surface finish. The experiment results were analyzed by ANOVA. The main factors and factors interaction that affected to surface finish were investigated. Effect of cutting speed, feed rate and depth of cut on surface finish of harden medium carbon steel was discussed.
