This is to inform you of a new heating method recently worked out by these writers, which they call Local Electric Resistance Heating Method. In this research, the effect of hot machining by this method on the surface roughness were investigated. Ceramic tools were used to turn carbon steel. The results of these experiments are as follows : (1) Until cutting speed exceeds the speed of 160m.p.m., we can expect to have surface roughness of better quality under or by new hot machining method than under or by usual machining. (2) At a higher cutting speed than 220m.p.m., surface roughness obtained remains the same whether electric current is used or not. (3) When the depth of cut is large, better surface roughness can be obtained by increasing cutting speed. (4) This method is quite effective, or applicable as a hot machining method.
