In this report, cutting resistance, surface roughness and tool wear were observed when SCM 4 steel was cut with carbide and ceramic tools under electric resistance heating : and then, the effects of the tool wear on the cutting resistance and on the surface roughness, tool life and heating method were discussed. The main results are as follows : (1) The decrease of grooving wear by heating the workpiece is due to the decrease of cutting resistance and surface roughness. (2) When the steel is cut with the carbide tool at the cutting speed of 80m/min, the heating of the workpiece makes the surface roughness better, the cutting resistance lower and the tool life longer. The same result is obtained when it is cut with the ceramic tool at the cutting speed of 100m/min. (3) I he heating method for the ceramic tool has many demerits and is difficult to be put into practice.
