Beschreibung:Description:
Die Erfindung betrifft ein Verfahren zur Korrektur der Positionsbestimmung von relativ zueinander bewegbaren Werkstücken und Werkzeugen in Bearbeitungsmaschinen, insbesondere CNC-Bearbeitungszentren, mit Hilfe von maschineninternen Meßsystemen. Die Erfindung betrifft auch eine Bearbeitungsmaschine, insbesondere CNC-Zentrum, zur Durchführung des Verfahrens.The invention relates to a method for correcting the position determination of workpieces and tools that can be moved relative to one another in processing machines, in particular CNC machining centers, with the aid of machine-internal measuring systems.

Neben der veränderten Raumtemperatur kann auch der Einsatz von Kühlmitteln zu unterschiedlichen Dehnungen führen. Selbst eine Anhäufung von thermisch belasteten Spänen z.B. bei der Trockenbearbeitung kann derartige Auswirkungen haben. Besonders bei schnelldrehenden Hauptspindeln kann es durch Lagererwärmung zu einem störenden Längenwachstum kommen. Alle diese thermisch bedingten Änderungen wirken sich im Arbeitsbereich des Werkzeuges auf die tatsächlichenRoom temperature to different, heat-related expansions on the machine bed, the workpiece carriers and workpieces as well as on the tool carriers or tools. In addition to the changed room temperature, the use of coolants can also lead to different expansions. Even an accumulation of thermally stressed chips e.g. Dry machining can have such effects. Especially in the case of high-speed main spindles, heating up the bearings can lead to lengthening problems. All of these thermal changes affect the actual working area of the tool

Regelmäßig werden die Positionen von Werkstück und Werkzeug mit Hilfe maschineninterner Meßsysteme erfaßt, die aber nicht die thermisch bedingten Positionsänderungen im Arbeitsbereich des Werkzeuges erfassen können.

The positions of the workpiece and the tool are regularly recorded with the aid of machine-internal measuring systems which, however, cannot record the thermally induced changes in position in the working area of the tool.

Vorzugsweise wird die jeweils erfaßte Position nach Bildung eines Korrekturwertes abgespeichert, so daß eine jeweils frühere Messung als Referenz für die nächstfolgende Messung dient. Mit dem erfindungsgemäßen Verfahren können alle Positionsänderungen von Werkstück und Werkzeug bzw. deren Träger im Arbeitsbereich des Werkzeuges, unabhängig davon, aus welcher Quelle sie stammen, erfaßt und zur Bildung eines Korrekturwertes für die Maschinensteuerung verwendet werden.

Zu der dargestellten Bearbeitungsmaschine gehört ein nur angedeutetes Maschinenbett 1 mit Schienen 2, auf denen ein Maschinentisch 3 und ein Werkstückträger mit darauf angeordnetem Werkstück 4 bewegbar ist. Die Schienen 2 erstrecken sich in Z-Richtung nach Maßgabe des in Fig. 1 rechts oben angedeuteten Koordinatenkreuzes 5. Zur Bearbeitungsmaschine gehört ferner eine in einem Spindelträger 6 gelagerte Spindel 7, deren Spindelnase 8 für den Anschluß eines nicht dargestellten Werkzeuges eingerichtet ist. Die Achse der Spindel 7 erstreckt sich ebenfalls in Z-Richtung. Der Spindelträger 6 mit der Spindel 7 ist in Z-Richtung bewegbar.The machine tool shown includes a machine bed 1, only indicated, with rails 2, on which a machine table 3 and a workpiece carrier with a workpiece 4 arranged thereon can be moved. The rails 2 extend in the Z direction in accordance with the coordinate cross 5 indicated at the top right in FIG. 1. The processing machine also includes a spindle 7 mounted in a spindle carrier 6, the spindle nose 8 of which is set up for the connection of a tool, not shown. The axis of the spindle 7 also extends in the Z direction. The spindle carrier 6 with the spindle 7 is movable in the Z direction.
Der Arbeitsbereich des nicht dargestellten Werkzeuges wird von einem optischen Strahl 9 gekreuzt, der sich bei der dargestellten Ausführung in einer X-Y-Ebene unter einem Winkel zur X-Richtung und damit orthogonal zur Z-Richtung erstreckt. Der ortsfeste Strahl 9 geht von einem Sender 10 aus und trifft einen Empfänger 11. Der Sender 10 und der Empfänger 11 sind an den einander gegenüberliegenden Seiten eines nicht dargestellten Gehäuses angeordnet, welches zumindest den Arbeitsbereich des Werkzeuges umgibt.The working area of the tool, not shown, is crossed by an optical beam 9 which, in the embodiment shown, extends in an X-Y plane at an angle to the X direction and thus orthogonally to the Z direction. The fixed beam 9 starts from a transmitter 10 and hits a receiver 11. The transmitter 10 and the receiver 11 are arranged on the opposite sides of a housing, not shown, which at least surrounds the working area of the tool.
Die Fig. 2a zeigt einen vergrößerten Teil des Werkstückes 4 mit einer Meßkante 12, die sich in X-Richtung erstreckt und in Z-Richtung weist. Die Spindelnase 8 besitzt als Meßkante 13 ihre Stirnfläche, die sich in eine X- Y-Ebene erstreckt.2a shows an enlarged part of the workpiece 4 with a measuring edge 12 which extends in the X direction and points in the Z direction. The spindle nose 8 has as its measuring edge 13 its end face, which extends in an X-Y plane.
Nicht dargestellt ist, daß sowohl dem Maschinentisch 3 bzw. dem Werkstückträger als auch dem Spindelträger 6 maschineninterne Meßsysteme zugeordnet sind, mit denen die jeweiligen Positionen von Werkstückträger 4 und Spindelträger 6 erfaßt werden, die dann dieIt is not shown that both the machine table 3 or the workpiece carrier and the spindle carrier 6 are assigned to machine-internal measuring systems with which the respective positions of workpiece carrier 4 and spindle carrier 6 are detected, which then
Grundlage für die Maschinensteuerung bilden. Diese maschineninternen Meßsysteme können aber nicht thermisch bedingte Verlagerungen der einzelnen Bauteile und daraus resultierende Positionsänderungen von Werkstück und/oder Werkzeug im Arbeitsbereich des Werkzeuges erfassen. Daraus sich ergebende Bearbeitungsungenauigkeiten werden erfindungsgemäß dadurch vermieden, daß das Werkstück 4 und das Werkzeug mit ihren jeweils zugeordneten Meßkanten 12 bzw. 13 gleichzeitig oder in kurzem Zeitabstand nacheinander durch den als ortsfeste optische Meßschranke dienenden Laserstrahl 9 bewegt werden, und zwar vorzugsweise in gleicher Richtung (Z-Richtung), daß bei Unterbrechung der Meßschranke die jeweiligen Positionen des Werkstücks 4 bzw. des Werkzeuges mit Hilfe des maschineninternen Meßsystems erfaßt werden, daß die erfaßten Positionen mit abgespeicherten Positionen aus einer früheren Messung verglichen werden und daß die Differenz zwischen der erfaßten Position und der abgespeicherten Position zur Korrektur der Maschinensteuerung verwendet wird. Insbesondere kann die jeweils erfaßte Position nach Bildung eines Korrekturwertes abgespeichert werden und damit den Referenzwert für die nächste Messung bilden. Es versteht sich, daß die erfaßten Positionen unabhängig vom maschineninternen Meßsystem abgespeichert werden.Form the basis for the machine control. However, these machine-internal measuring systems can not detect thermally induced displacements of the individual components and resulting changes in position of the workpiece and / or tool in the working area of the tool. Machining inaccuracies resulting therefrom are avoided according to the invention in that the workpiece 4 and the tool with their respectively assigned measuring edges 12 or 13 are moved simultaneously or at short intervals in succession by the laser beam 9 serving as a fixed optical measuring barrier, preferably in the same direction ( Z direction) that when the measuring barrier is interrupted the respective positions of the workpiece 4 or the tool are detected with the aid of the machine's internal measuring system, that the detected positions are compared with stored positions from an earlier measurement and that the difference between the detected position and the saved position is used to correct the machine control. In particular, the position recorded in each case can be stored after formation of a correction value and thus form the reference value for the next measurement. It is understood that the detected positions are saved independently of the machine's internal measuring system.
