Description
Bearbeitung
rotierender Werkstücke
mit einer Werkzeugmaschine gemäß Oberbegriff
des Patentanspruchs 1. Im Stand der Technik werden drallfreie Werkstückoberflächen mit
definierter Schneide erzeugt, wobei die Werkzeugschneide gegenüber der
Rotationsachse des Werkstücks
geneigt ist. Die
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Bearbeitung sowohl unrunder als auch rotationssymmetrischer Innen- und Außenkonturen von Werkstückoberflächen mit verbesserter Fertigungsqualität zu schaffen.Of the Invention is based on the object, a method for processing both non-circular and rotationally symmetrical inner and outer contours of workpiece surfaces with improved production quality to accomplish.
Zur Lösung dieser Aufgabe wird ein Verfahren nach Anspruch 1 vorgeschlagen.to solution This object is proposed a method according to claim 1.
Ein vorteilhafter Aspekt der Erfindung besteht darin, die Schwenkachse des Werkzeugs relativ zur Schneide so anzuordnen, dass die durch die Schneidenform bedingten Konturabweichungen ohne Richtungswechsel in der Zustellbewegung ausgeführt werden. Dazu muss die Projektion der Schneidkante auf eine rechtwinklig zur Werkstückrotationsachse angeordnete Ebene gegenüber der Verbindungslinie zischen den Drehpunkten von Werkzeug und Werkstück um einen Winkel α geneigt sein, der während der Vorschubbewegung entweder kleiner gleich 90° ist oder größer gleich 90° ist. Im Folgenden wird die Erfindung an Hand eines Ausführungsbeispiels näher beschrieben.One Advantageous aspect of the invention is the pivot axis the tool relative to the cutting edge to be arranged so that through the cutting edge contour deviations without changing direction executed in the delivery movement become. To do this, the projection of the cutting edge must be at a right angle to the workpiece rotation axis arranged plane opposite The connecting line hisses the pivot points of the tool and workpiece by one Angle α inclined be that while the feed movement is either less than or equal to 90 ° or greater than or equal to 90 °. in the The invention will be described in more detail below with reference to an exemplary embodiment.
