Effect of Additional Current on Machinability of Free Machining Steels-Machining of BN Added Steels with Additional Current

Abstract

This study deals with the machinability of steels in turning with additional current. Tested work materials were plane carbon steel JIS S45C and BN added steel which has good machinability at high cutting speed. Turning tests were performed by carbide tool P30 in order to investigate the influence of electrical conditions of closed circuit system on the cutting mechanism of BN added steel. The tool life and cutting force was investigated practically and these results were discussed.
