A Study on the Effects of Cutting Resistance and Surface Roughness in Turning

선삭가공에서 절삭지향과 표면거칠기에 미치는 영향에 관한 연구

The purpose of this study was to determine the effects of various cutting conditions on the cutting resistance and surface roughness of material in turning operation using a carbide tool. The workpiece materials were the carbon steel SM20C and SM45C. The results of this study are summarized as follows: The cutting force decreases as the feeding amount and cutting depth decrease and the cutting speed increases. In order to obtain a proper surface roughness to each material, it is desirable to set the feeding amount as 0.059mm/rev, the cutting depth as 0.4mm and the cutting speed as 270m/min for SM20C, while setting the feeding as 0.059mm/rev, the cutting depth as 0.6mm and the cutting speed as 270m/min for SM45C.
