Three grades of carbon steel (S 15 C, S 40 C, and SK 4) which contain four different kinds of lamellar pearlite microstructure for each grade were machined for the tests of tool life and surface finish. The effect of spheroidized pearlite structure in high carbon steels on machinability was compared with that of lamellar pearlite structure. The effects of nonmetallic constituent and crystal grain in steels on tool life were also discussed. It was found that the microstructure of lamellar portion of pearlite in carbon steels affects the machinability based upon the tool life and surface finish, and that spheroidized pearlite structure improves the machinability better than lamellar pearlite structure.
