Abstract

A chamfer (3) is provided along the sheath edge, with the chamfer angle (1) made variable along the sheath edge.

Description

Schneiden, welche der spanenden Bearbeitung metallischer Werkstoffe dienen, werden zum Teil zwischen der Spanfläche (2) und der Freifläche (4) mit einer Fase (3) versehen. Diese Fase dient verschiedenen Zwecken, z.B. der Beeinflussung der Spanbildung sowie der Erhöhung der Schneidenstandzeit. Es ist bekannt, dass sowohl die Schneidenbelastung, als auch die Spanbildung sowie die Randzonenbeeinflussung des Werkstücks durch den Winkel, den die Fase gegenüber der Spanfläche einnimmt (Fasenwinkel (1)), beeinflusst wird. Schneiden zur Dreh- und Fräsbearbeitung werden bisher mit einer Fase versehen, welche gegenüber der Freifläche einen gleichbleibenden Winkel aufweist. Entlang solch einer Fase herrschen unterschiedlich hohe Beanspruchungen, welche sich z.B. in unterschiedlich starken Verschleißerscheinungen bemerkbar machen können.Cutting edges that are used for the machining of metallic materials are partially between the rake face ( 2 ) and the open space ( 4 ) with a bevel ( 3 ) Mistake. This chamfer serves various purposes, such as influencing chip formation and increasing the tool life. It is known that both the cutting edge load and the chip formation as well as the edge zone influence of the workpiece by the angle that the chamfer makes relative to the rake surface (chamfer angle ( 1 )), being affected. Knives for turning and milling have so far been provided with a chamfer, which has a constant angle with respect to the free surface. Along such a chamfer, there are different levels of stress, which can be felt, for example, in different degrees of wear.

Die Erfindung sieht einen entlang der Schneidenkante variierenden Fasenwinkel vor. Dieser kann unter anderem dazu genutzt werden, die Standzeit der Schneide zu erhöhen, oder eine bessere Oberflächenqualität des Werkstücks zu erzielen. Die Erfindung beschränkt sich auf Schneiden, welche in der Dreh- und Fräsbearbeitung zum Einsatz kommen.The invention looks along bevel angle varying the cutting edge. This can be found under are used to increase the service life of the cutting edge, or to achieve a better surface quality of the workpiece. The Invention limited on cutting edges that are used in turning and milling.
