A Study on the effects of surface roughness in CNC lathe over various cutting conditions

In the CNC lathe working, the study of the effects of various cutting conditions on cut surface roughness is less active than that of the ordinary latee. After lathe working of SM45C, a carbon steel material for machine structure, its surface roughness was measured using a stylus surface roughness tester. In most cases, good surface roughness was obtained over 160m/min cutting speed and then the proper cutting depth was found as 1.0~1.5mm.
