Abstract
The applications of a new cut off tool equipped with a grooved rake face are discussed in relation to the cutting performance compared with that of the conventional (flat-rake-face) cut off tool. The experimental results indicate the followings :1) cutting surface roughness and chip disposal are improved and cutting forces are decreased ;2) cutting forces and their fluctuations are markedly decreased as the oxygen jet is supplied to the tool edge at the range of cutting speed in which the built-up edges grow ;3) the ceramic cut off tool is capable of grooving steel work since the cut off tool has a grooved rake face and the oxygen jet is supplied to the tool edge.
