Study on Hot Machining (2nd Report)

In this report, surface roughness and tool wear when 18-8 stainless steel and 13Cr stainless steel were cut with ceramic tool under Local Electric Resisitance Heating are shown. The results of these experiments are as follows. (1) A better surface roughness is expected of both of the work materials when this method is used. (2) When this method is used, cratering for 18-8 stainless steel decreases. But for 13Cr stainless steel, cratering little decreases. (3) When machining 18-8 stainless steel and 13Cr stainless steel with ceramic tool, cutting speed must be kept at a higher point than 100m/min.
