Abstract
Description
Die
Erfindung betrifft ein Verfahren und eine Vorrichtung zur hochgenauen
Bearbeitung gehärteter Werkstücke mit sowohl unrunden
als auch rotationssymmetrischen Innen- und Außenkonturen.
Bei der industriellen Serienfertigung von solchen Werkstücken,
beispielsweise bei der Herstellung von Sitzen für Lager
oder Dichtringe, wird das gehärtete Werkstück
einer Hartdrehbehandlung unterzogen und dann geschliffen. Aus der
Aufgabe der Erfindung ist es, ein Verfahren anzugeben, das rasche und kostengünstige Bearbeitung gehärteter Werkstücke bei hoher Oberflächenqualität und Maßgenauigkeit ermöglicht. Es ist auch Aufgabe der Erfindung, eine Vorrichtung zur Durchführung des Verfahrens bereitzustellen.task The invention is to provide a method which is rapid and inexpensive Machining of hardened workpieces with high surface quality and dimensional accuracy allows. It is also a task of the invention, an apparatus for carrying out the method provide.
Diese Aufgabe wird gelöst durch ein Verfahren nach Anspruch 1 und eine Werkzeugmaschine nach Anspruch 5. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.These The object is achieved by a method according to claim 1 and a machine tool according to claim 5. Advantageous developments The invention are the subject of the dependent claims.
Ein vorteilhafter Aspekt der Erfindung besteht darin, die Hartbearbeitung mit definierter Schneide durch Erhöhen der Vorschubgeschwindigkeit zu beschleunigen und dadurch die Zykluszeit für die Werkstückbearbeitung zu verkürzen. Dabei wird die Werkzeugschneide für die Dauer des Eingriffs mit dem Werkstück in einer Richtung orthogonal zur Werkstückrotationsachse bewegt, so dass die Vorschubbewegung parallel oder in kleinen Winkeln zur Schneidkante verläuft. Erfindungsgemäß wird die erhöhte Vorschubgeschwindigkeit durch optimierte Auslegung der Werkzeugwinkel erreicht. Dabei waren der Anstellwinkel, also die Schneidenausrichtung relativ zur Werkstückachse, und die besonderen geometrischen Verhältnisse bei der Werkzeugbewegung orthogonal zur Werkstückrotationsachse zu berücksichtigen. Eine Schwenkbewegung des Werkzeugs relativ zum Werkstück verursacht zusätzliche Veränderungen der Einstell- und Freiwinkel. Diese sind ebenfalls in Betracht zu ziehen. Bei einem Anstellwinkel von 30° bis 60° wurde für den Keilwinkel an der Werkzeugschneide ein Bereich von 80° bis 135° ermittelt. Vorteilhafte Werte für den negativen Spanwinkel liegen im Bereich von ca. –1° bis –15° und für den Freiwinkel bei 5° bis 30°. Auf diese Weise werden derzeit Vorschubgeschwindigkeiten von bis zu 900 mm/min erzielt. Bei der Hartbearbeitung mit definierter Schneide wird ein minimales Schleifaufmaß so gewählt, dass unvermeidliche Geometriefehler sicher korrigiert werden können. Beim anschließenden Schleifvorgang ist der Werkzeugverschleiß durch die regelmäßigen Abrichtvorgänge leicht zu überwachen. Daher kann die gewünschte Fertigungsqualität auch mit stichprobenartigen Werkstückkontrollen sichergestellt werden. Im Vergleich zum Stand der Technik resultieren daraus erhebliche Zeit- und Kostenvorteile.One Advantageous aspect of the invention is the hard machining with defined cutting edge by increasing the feed speed to accelerate and thereby the cycle time for the workpiece machining To shorten. The tool cutting edge for the duration of engagement with the workpiece in one direction moved orthogonal to the workpiece rotation axis, so that the feed motion parallel or at small angles to the cutting edge runs. According to the invention is the increased Feed rate through optimized design of the tool angle reached. The angle of attack, ie the orientation of the blades, was relative to the workpiece axis, and the special geometric conditions in the tool movement orthogonal to the workpiece rotation axis to take into account. A pivoting movement of the tool relative to the workpiece causes additional changes the adjustment and clearance angle. These are also eligible pull. At an angle of attack of 30 ° to 60 ° was for the wedge angle on the tool cutting an area determined from 80 ° to 135 °. Advantageous values for the negative rake angle are in the range of about -1 ° to -15 ° and for the clearance angle at 5 ° to 30 °. On Currently, feed rates of up to 900 mm / min achieved. For hard machining with a defined cutting edge a minimum grinding allowance is chosen so that inevitable geometric errors can be safely corrected. During the subsequent grinding process the tool wear is through the regular dressing operations easily to monitor. Therefore, the desired manufacturing quality also ensured with random workpiece checks become. Compared to the state of the art, this results in considerable time and cost advantages.
Im Folgenden wird die Erfindung an Hand von Ausführungsbeispielen näher erläutert.in the The invention is based on exemplary embodiments explained in more detail.
