APPARATUS AND METHOD FOR MACHINING OF HARD METALS WITH REDUCED DETRIMENTAL WHITE LAYER EFFECT

An apparatus and a method are disclosed for reducing a thickness of a thermomechanically-affected layer on an as-machined surface of a hard metal workpiece being machined by a hard cutting tool exerting a thermomechanical load on a surface of the workpiece. The method involves reducing the thermomec...

Beschreibung
Zusammenfassung:	An apparatus and a method are disclosed for reducing a thickness of a thermomechanically-affected layer on an as-machined surface of a hard metal workpiece being machined by a hard cutting tool exerting a thermomechanical load on a surface of the workpiece. The method involves reducing the thermomechanical load on the surface of the workpiece, and the apparatus includes a means for reducing the thermomechanical load on the surface of the workpiece. L'invention concerne un appareil et un procédé permettant de réduire l'épaisseur d'une couche affectée de manière thermomécanique sur une surface quasi usinée d'une pièce métallique dure usinée au moyen d'un outil de coupe dur exerçant une charge thermomécanique sur une surface de ladite pièce. Ledit procédé consiste à réduire la charge thermomécanique sur la surface de la pièce, et l'appareil comprend des moyens permettant de réduire ladite charge thermomécanique sur la surface de la pièce.
