The effect of magnetization on the wear of high speed steel tools

Abstract A physicochemical method for improving the life of high speed steel (HSS) tools is reported. Mild steel workpieces were turned using magnetized HSS tools. Response surface methodology was used to investigate the effects of speed, feed and depth of cut on tool life and a second-order tool life model was adopted. The analysis of variance shows that both the first-order and second-order terms have a significant influence on the life of magnetized tools. Results obtained in normal cutting showed that the tool life can be increased two to four times by magnetization.
