This study aims to investigate the formation mechanism of Belag and the adhesion situation to the tool. After brief cutting times, formation area was observed by TEM. Belag prevent direct contact to tool without reactive zone at a short time within 10 second. In this study, the effect the voltage on Belag formation was investigate using by constant voltage power supply. consequently, the tool wear was suppressed by impressing it in same discretion of the current as the thermal electromotive force.
