In this paper, a series of milling tests were carried out in order to identify the effects of feed rate and depth of cut on cutting forces and surface roughness while end milling the mild steel using NOVIANO and conventional cutting tools. Slot-milling operations were conducted. The cutting forces and surface roughness in a wide range of feed rate (value according to manufactured of cutting tool) and depth of cut were discussed. Results showed that the cutting forces for the Fx and Fy increase with the increase of feed rate for both cutting tool. Further increasing the speed of feed rate, the surface roughness also improves for both cutting tool. However, the comparison between both cutting tool, it was found that the cutting force and surface roughness much better for NOVIANO.
