INFLUENCE DU CHAMP MAGNETIQUE SUR LE COMPORTEMENT EN USURE D’UN OUTIL DE COUPE DURANT LES OPERATIONS DE CHARIOTAGE

Abstract

In this work, we have studied the effect of the magnetic field on the behavior of a tool wear during charioting operations from the loss of mass during the wear cut and nature. Throughout experiences, we have noted the existence of a critical value of the magnetic field equalling to 0.34 T, which has provoked a non negligible resistance to wear and determined its nature regarding the factor that has a direct effect on the behavior of the tool wear notably the cut speed. We noted that the magnetic field decreases the loss of mass and preserves the nature of the cutting bone of the tool. In some conditions, we noticed that it leads to a change of the wear nature.
