Cutting Performance of Stainless Steel by Tipped-Saw for Power Tools

Abstract

We tried to experiment on the dry interrruptied cutting of austenitic stainless steel plates(SUS304) using power tools with cermet tipped-saw. The purpose of this paper was to investigate the effect of cutting speed on the cermet wear mechanism and wear damage of tip, and then to compare these results with those on cemented carbide. It was found that the cutting temperature of workpiece became 350-420K at the first cutting, and rapidly increased up to 1, 470 K at the end of tipped-saw life, and then the wear occurred by a repeat of adhesives formed in the built-up edge and spalling. Some discussions were made on these results.
