Abstract

Method for processing non-round and also rotationally symmetrical inner and outer contours of a rotating workpiece (7) comprises producing an adjusting movement between a workpiece and a tool (15) and comparing contour deviations of the workpiece. An independent claim is also included for a machine tool (1) for processing non-round and also rotationally symmetrical inner and outer contours of a rotating workpiece. Preferred Features: The tool blade is displaced in the direction of the axis of rotation of the workpiece depending on the size of the parameter of the workpiece surface being processed until the workpiece surface is completely processed.

Description

Die Erfindung betrifft ein Verfahren und eine Werkzeugmaschine zur Bearbeitung sowohl unrunder als auch rotationssymmetrischer Innen- und Außenkonturen an einem rotierenden Werkstück nach dem Oberbegriff des Patentanspruches 1 und des Patentanspruches 5. Die Drehbearbeitung weicher oder gehärteter Werkstücke mit bestimmter Schneide ist Stand der Technik. Beim Längsdrehen entsteht auf der Werkstückoberfläche durch den Vorschub des Werkzeuges entlang des rotierenden Werkstücks zwangsläufig eine gewindeartige Struktur in Form von Drehriefen oder Werkstückerhebungen. Zur Vermeidung solcher Drehriefen ist aus der DE 10 2004 026 675 B3 ist ein Verfahren zum spanenden Bearbeiten rotationssymmetrischer Flächen eines Werkstücks bekannt. Dabei wird die Werkzeugschneide in Form einer zur Werkzeugrotatiansachse koaxialen Schraubenlinie mit einer kreisbogenförmigen Vorschubbewegung um die Werkzeugrotationsachse bewegt, so dass die Wirkstelle zwischen Schneide und Werkstück entlang der Schneide wandert. Die Herstellung und Wartung von schraubenartigen Schneiden, die koaxial zur Werkzeugrotationsachse verlaufen ist vergleichsweise aufwendig und teuer. Außerdem ist dieses Verfahren ist zur Bearbeitung unrunder Werkstückkonturen nicht geeignet. Aus der DE 198 40 738 C2 ist ein Drehverfahren mit Schneidkanten, welche eine zur zu erzeugenden Werkstückgeometrie angepasste Form aufweisen, bekannt. Da die Schneidkanten über ihre gesamte Länge zur gleichen Zeit auf das Werkstück einwirken, ist bei diesem Verfahren die maximale Schneikantenlänge wegen der erhöhten Schnittkräfte deutlich eingeschränkt. Die DE 94 22 389 U1 zeigt eine Werkzeugschneiden-Verstelleinrichtung zum hochgenauen Bearbeiten runder oder unrunder Innen- und/oder Außenkonturen. Diese Verstelleinrichtung ist für besonders kleine Schneidenauslenkungen mit hohen Auslenkungsfrequenzen konzipiert.The invention relates to a method and a machine tool for processing both non-circular and rotationally symmetrical inner and outer contours on a rotating workpiece according to the preamble of claim 1 and of claim 5. The rotation of soft or hardened workpieces with certain cutting edge is state of the art. During longitudinal turning, a thread-like structure in the form of rotational depths or workpiece elevations inevitably arises on the workpiece surface as a result of the feed of the tool along the rotating workpiece. To avoid such turning depths is from the DE 10 2004 026 675 B3 a method for machining rotationally symmetrical surfaces of a workpiece is known. In this case, the tool cutting edge is moved around the tool rotation axis in the form of a helix coaxial with the tool rotation axis, with an arcuate feed movement, so that the point of action travels between the cutting edge and the workpiece along the cutting edge. The production and maintenance of helical cutting edges, which extend coaxially to the tool rotation axis is comparatively complicated and expensive. In addition, this method is not suitable for machining non-circular workpiece contours. From the DE 198 40 738 C2 is a turning process with cutting edges, which have a shape adapted to be generated workpiece geometry, known. Since the cutting edges act on the workpiece over their entire length at the same time, in this method the maximum length of the cutting edge is significantly limited because of the increased cutting forces. The DE 94 22 389 U1 shows a cutting tool adjusting device for high-precision machining of round or non-circular inner and / or outer contours. This adjustment is designed for very small cutting deflections with high deflection frequencies.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Bearbeitung sowohl unrunder als auch rotationssymmetrischer Innen- und Außenkonturen von Werkstückoberflächen zu schaffen und zusätzlich die Werkzeugkosten unter Beibehaltung drallfreier Werkstückoberflächen zu senken.Of the Invention is based on the object, a method and an apparatus for machining both non-circular and rotationally symmetric Inner and outer contours of workpiece surfaces too create and in addition to reduce tooling costs while maintaining swirl-free workpiece surfaces.

Zur Lösung dieser Aufgabe wird ein Verfahren nach Patentanspruch 1 und eine Werkzeugmaschine nach Patentanspruch 5 vorgeschlagen. Vorteilhafte Ausführungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.to solution This object is a method according to claim 1 and a Machine tool according to claim 5 proposed. advantageous versions and further developments of the invention will become apparent from the dependent claims.

Der Kerngedanke der Erfindung besteht darin, ein Werkzeug mit einer ebenen, schräg zur Werkstückrotationsachse verlaufenden Schneide, die mit einer kreisbogenförmigen Vorschubbewegung um eine Schwenkachse bewegt wird, zur Erzielung drallfreier Werkstückoberflächen einzusetzen. Dabei werden die durch die ebene Schneidenform bedingten Konturabweichungen des Werkstücks durch eine Relativbewegung zwischen Werkstück und Werkzeug ausgeglichen. Auf diese Weise können auch unrunde Werkstückkonturen, wie zum Beispiel Nockenformen, bearbeitet werden. Nach diesem Verfahren lassen sich besonders hochwertige Werkstückoberflächen mit geringer Rautiefe herstellen. Da die Werkzeugschneide eben ist, können kostengünstige Wendeplatten mit gerader, gebogener oder kreisbogenförmiger Schneidkante eingesetzt werden, welche auch für die Hartbearbeitung in der erforderlichen Qualität im Handel verfügbar sind.Of the The core idea of the invention is to provide a tool with a even, oblique to the workpiece rotation axis extending cutting edge, which with a circular arc feed movement to a Swivel axis is moved to use to achieve swirl-free workpiece surfaces. In the process, the contour deviations caused by the flat cutting edge shape become of the workpiece balanced by a relative movement between the workpiece and the tool. That way you can also non-circular workpiece contours, such as cam shapes are processed. After this procedure Particularly high quality workpiece surfaces with low roughness can be used produce. Since the tool cutting edge is flat, cost-effective inserts can used with straight, curved or circular cutting edge which are also for hard machining in the required quality are commercially available.

Bei der erfindungsgemäßen Vorrichtung sind die Rotationsachsen des Werkzeugrevolvers und des Werkstücks parallel angeordnet. Dadurch kann die kreisbogenförmige Vorschubbewegung der Werkzeugschneide besonders vorteilhaft durch eine Schwenkbewegung des Werkzeugrevolvers ausgeführt werden.at the device according to the invention the rotation axes of the tool turret and the workpiece are parallel arranged. As a result, the circular arc-shaped feed movement of the Tool cutting particularly advantageous by a pivoting movement of the tool turret become.
