In this paper, the cutting resistance and surface roughness in deformed layer were tested for various cutting conditions of face milling. The face milling was performed on carbon steel(SM45C) and austenite stainless steel(STS304) by CNC machining center using 8 blades throw-away tip tool. Experimental tests were carried out by tool dynamometer and surface roughness tester. The results could be summarized ; 1. Cutting resistance in the direction of feed was influenced by depth of cut and cutting speed. 2. Surface roughness was increased at higher cutting speed when feed rate and depth of cut were held constant. 3. The optimal cutting conditions for face milling were 200 m/min cutting speed with 300 mm/min feed rate in SM45C, and 100 m/min cutting speed with 100 mm/min feed rate in STS304.
