Hadfield steels are the materials having with high wear resistance, toughness, high yield and tensile strength. Hadfield steels, also known as rail steels, are commonly used for rail transport due to their wear, impact and fatigue strength. In this study, machining behavior of the Hadfield steels and the effect of the machining parameters on surface roughness, machine noise and power consumption were investigated under dry cutting conditions using horizontal milling machine. Experimental studies were carried out a real production environment using constant cutting speed, four different feed rate and six different depth of cut under heavy machining conditions. The influence of the milling variables on surface roughness, machine noise and power consumption were evaluated by using Analysis of variance (ANOVA). The experimental results showed that the depth of cut was the most significant cutting parameter on the surface roughness. Surface roughness value was remarkably improved with increasing depth of cut. Power consumption and machine noise were affected from increasing feed rate and depth of cut values used in the experiments.
