Description
Die vorliegende Erfindung betrifft eine Vorrichtung und ein Verfahren zur Bearbeitung von Oberflächen eines Bauteils, bei welchem die zu bearbeitende Oberfläche von einem Schleiffluid umströmt wird, das aus einem Fluid mit darin enthaltenen Schleifpartikeln gebildet ist.The present invention relates to an apparatus and a method for processing surfaces of a component, wherein the surface to be processed is flowed around by a grinding fluid, which is formed from a fluid with abrasive particles contained therein.
Zur Bearbeitung von Oberflächen von Bauteilen ist es bekannt, Schleifverfahren einzusetzen, bei denen abrasive Partikel Material aus der zu bearbeitenden Oberfläche entfernen. Durch die Verwendung von entsprechend feinen bzw. klein dimensionierten, abrasiven Partikeln kann durch eine entsprechende Oberflächenbearbeitung beispielsweise eine Glättung der Oberfläche erzielt werden.For machining surfaces of components, it is known to use grinding methods in which abrasive particles remove material from the surface to be processed. By using appropriately fine or small-sized, abrasive particles, for example, a smoothing of the surface can be achieved by a corresponding surface treatment.
Neben den bekannten, üblichen Schleifverfahren, bei denen die abrasiven Stoffe in Form von Schleifpapier oder Schleifscheiben relativ zu der zu bearbeitenden Oberfläche bewegt werden, ist es auch bekannt, Schleifpartikel in einem Fluid relativ zur Oberfläche zu bewegen. Als Beispiel kann hier das Sandstrahlen genannt werden, bei dem Sandpartikel in einem Luftstrom auf die zu bearbeitende Oberfläche auftreffen und somit eine Oberflächenbearbeitung bewirken. Darüber hinaus ist auch das Strömungsschleifen, manchmal auch als Druck-Fließ-Läppen bezeichnet, bekannt, bei welchem ein flüssiges Fluid mit Schleifpartikeln zwischen zwei Stempeln hin und her bewegt wird, wobei im oder am Fließkanal für das Schleiffluid das zu bearbeitende Bauteil angeordnet ist.In addition to the known, conventional grinding methods in which the abrasive substances in the form of abrasive paper or grinding wheels are moved relative to the surface to be processed, it is also known to move abrasive particles in a fluid relative to the surface. As an example, sandblasting can be mentioned here, in which sand particles impinge on the surface to be treated in an air flow and thus effect a surface treatment. In addition, flow grinding, sometimes referred to as pressure-flow lapping, is also known in which a liquid fluid with abrasive particles is reciprocated between two punches, with the component to be processed being disposed in or on the flow channel for the abrasive fluid.
Nachteilig bei diesen bekannten Verfahren zur Bearbeitung von Oberflächen ist jedoch, dass bei diesen Verfahren Hohlräume von Bauteilen, die Hinterschneidungen aufweisen, kaum bearbeitet werden können, da hier innere Oberflächen vorliegen, die einem geradlinigen Strömungsfluss oder einem Schleifwerkzeug nicht zugänglich sind. Beispielsweise können mit den bekannten Schleifverfahren keine inneren Oberflächen von hohlen Bauteilen bearbeitet werden, die lediglich einen im Vergleich zum Durchmesser des Hohlraums klein ausgebildeten Zugang aufweisen. Allerdings ist es bei hochbelasteten Strukturbauteilen, wie sie beispielsweise in Strömungsmaschinen, wie stationären Gasturbinen oder Flugtriebwerken, Verwendung finden, erforderlich, dass die Oberflächen glatt ausgebildet sind, um durch Vermeidung von Risseinleitungsquellen an rauen Oberflächen die Festigkeit zu steigern. Entsprechend besteht Bedarf, ein Verfahren bereitzustellen, mit dem kontrolliert eine hohe Oberflächengüte im Bereich von inneren Oberflächen von hohlen Bauteilen geschaffen werden können.A disadvantage of these known methods for processing surfaces, however, is that in these methods cavities of components having undercuts, can hardly be processed, since there are inner surfaces that are not accessible to a straight flow or a grinding tool. For example, the known grinding processes can not process internal surfaces of hollow components are only having a small compared to the diameter of the cavity access formed. However, in highly stressed structural components, such as those used in turbomachines, such as stationary gas turbines or aircraft engines, it is necessary for the surfaces to be smooth to increase strength by avoiding sources of crack initiation on rough surfaces. Accordingly, there is a need to provide a method that can be used to controllably provide high surface finish in the area of interior surfaces of hollow components.
Es ist deshalb Aufgabe der vorliegenden Erfindung, eine Vorrichtung sowie ein Verfahren zur Bearbeitung von Oberflächen eins Bauteils bereitzustellen, bei dem insbesondere innere Oberflächen von Hohlräumen mit Hinterschneidungen kontrolliert bearbeitbar sind. Gleichzeitig soll das Verfahren einfach durchführbar und die entsprechende Vorrichtung sowohl einfach aufgebaut, als auch einfach bedienbar sein.It is therefore an object of the present invention to provide an apparatus and a method for processing surfaces of a component, in which in particular inner surfaces of cavities with undercuts are machined controlled. At the same time the method should be easy to carry out and the corresponding device both simple in design, and easy to use.
Diese Aufgabe wird gelöst durch ein Verfahren mit den Merkmalen des Anspruchs 1 sowie einer Vorrichtung mit den Merkmalen des Anspruchs 11. Vorteilhafte Ausgestaltungen sind Gegenstand der abhängigen Ansprüche.This object is achieved by a method having the features of
Der vorliegenden Erfindung liegt die Erkenntnis zugrunde, dass eine Relativbewegung zwischen einem Schleiffluid, welches in einem Fluid Schleifpartikel enthält, und dem Bauteil nicht nur dadurch realisiert werden kann, dass das Schleiffluid bewegt wird, sondern auch umgekehrt, dass das Bauteil bewegt wird und das Schleiffluid weitgehend ortsfest gehalten wird. Die entsprechende Umkehrung der Bewegung hat den Vorteil, dass das Schleiffluid in entsprechende Hohlräume eindringen kann und es aufgrund der Bewegung des Bauteils sowie der Trägheit des Schleiffluids zu einer Relativbewegung zwischen Schleiffluid und Bauteil bzw. inneren Oberflächen des Bauteils kommt, sodass auch innere Oberflächen des Bauteils bearbeitbar sind.The present invention is based on the finding that a relative movement between a grinding fluid, which contains abrasive particles in a fluid, and the component can be realized not only by moving the grinding fluid but also conversely by moving the component and the grinding fluid is largely kept stationary. The corresponding reversal of the movement has the advantage that the grinding fluid can penetrate into corresponding cavities and due to the movement of the component and the inertia of the grinding fluid to a relative movement between abrasive fluid and component or inner surfaces of the component, so that internal surfaces of the component are editable.
Um die Trägheit des Schleifmediums für die Relativbewegung zwischen Schleiffluid und Bauteil besonders auszunutzen, kann die Bewegung des Bauteils insbesondere oszillierend erfolgen, also in einer Hin - und Herbewegung.In order to make particularly good use of the inertia of the grinding medium for the relative movement between the grinding fluid and the component, the movement of the component can be effected in an oscillating manner, ie in a reciprocating motion.
Die Bewegung des Bauteils kann eindimensionale, zweidimensionale und/oder dreidimensionale Bewegungen umfassen. Eine eindimensionale Bewegung ist beispielsweise eine lineare Hin- und Herbewegung, während eine zweidimensionale Bewegung beispielsweise durch eine Kreisbewegung oder Teilkreisbewegung realisiert werden kann. Dreidimensionale Bewegungen sind darüber hinaus Bewegungen, die frei im gesamten Raum durchgeführt werden können.The movement of the component may comprise one-dimensional, two-dimensional and / or three-dimensional movements. A one-dimensional movement is, for example, a linear reciprocating movement, while a two-dimensional movement can be realized, for example, by a circular movement or pitch circle movement. Three-dimensional movements are also movements that can be performed freely throughout the room.
Die Bewegung des Bauteils relativ zum Schleiffluid kann durch eine Überlagerung mehrerer Einzelbewegungen erzielt werden, sodass insbesondere komplexe, dreidimensionale Bewegungen möglich sind. Eine leichte Realisierung der Überlagerung von verschiedenen Einzelbewegungen zu komplexen dreidimensionalen Bewegungen ist durch Translationsbewegungen entlang unabhängiger Raumachsen und/oder Drehbewegungen um unabhängige Drehachsen möglich.The movement of the component relative to the grinding fluid can be achieved by a superposition of several individual movements, so that in particular complex, three-dimensional movements are possible. An easy realization of the superposition of different individual movements to complex three-dimensional movements is possible by translational movements along independent spatial axes and / or rotational movements about independent axes of rotation.
Die Bewegungen des zu bearbeitenden Bauteils können während der Bearbeitung variiert und/oder für die einzelnen Anwendungsfälle individuell ausgewählt werden.The movements of the component to be processed can be varied during processing and / or individually selected for the individual application cases.
Zur Realisierung der Bewegung eines Bauteils relativ zu einem Schleiffluid kann ein Behälter vorgesehen werden, in dem das Fluid angeordnet werden kann. Das Bauteil kann zumindest bezüglich eines Bewegungsfreiheitsgrads ortsfest, vorzugsweise komplett ortsfest bezüglich aller Bewegungsfreiheitsgrad relativ zu und in dem Behälter aufgenommen werden, sodass durch eine Bewegung des Behälters und der Trägheit des Schleiffluids eine Relativbewegung zwischen zu bearbeitenden Bauteil und Schleiffluid eingestellt werden kann.To realize the movement of a component relative to a grinding fluid, a container can be provided in which the fluid can be arranged. The component can be accommodated, at least with respect to a degree of freedom of movement, stationary, preferably completely stationary relative to all degrees of freedom of movement relative to and in the container, so that a relative movement between the component to be processed and the grinding fluid can be set by movement of the container and the inertia of the grinding fluid.
Nach einem Ausführungsbeispiel kann der Behälter in der Art einer Kugel oder kugelförmig ausgebildet sein und so hergerichtet sein, dass er um mindestens zwei, vorzugsweise drei senkrecht zueinander angeordnete Drehachsen drehbar ist.According to one embodiment, the container may be formed in the manner of a ball or spherical and be prepared so that it is rotatable about at least two, preferably three mutually perpendicular axes of rotation.
Das Schleiffluid kann als Suspension ausgebildet sein, wobei das Fluid eine Flüssigkeit auf Wasser- und/oder Ölbasis sein kann, während die Schleifpartikel aus Diamant, diamantähnlichen Werkstoffen, diamantartigem Kohlenstoff, Karbiden, Oxiden, insbesondere Aluminiumoxid und Kombinationen daraus gebildet sein können.The abrasive fluid may be formed as a suspension, which fluid may be a water and / or oil based fluid, while the abrasive particles may be formed from diamond, diamond like materials, diamond like carbon, carbides, oxides, especially alumina, and combinations thereof.
Das Schleiffluid kann zusätzlich ein Dispergiermittel umfassen, um eine stabile Suspension aufrecht zu erhalten.The abrasive fluid may additionally comprise a dispersant to maintain a stable suspension.
Mit dem erfindungsgemäßen Verfahren können insbesondere Bauteile von Strömungsmaschinen, wie stationären Gasturbinen oder Flugtriebwerken, wie beispielsweise Leit- oder Laufschaufeln, sogenannte Blisken, also Kombinationen aus Scheiben und Schaufeln (blisk aus blade und disk) oder andere Bauteile mit Hohlräumen und Hinterschneidungen bearbeitet werden.In particular, components of turbomachines, such as stationary gas turbines or aircraft engines, such as guide blades or rotor blades, so-called blisks, ie combinations of disks and blades (blisk of blade and disk) or other components with cavities and undercuts, can be processed with the method according to the invention.

In der Bearbeitungskugel 1 ist weiterhin ein Schleiffluid vorgesehen, welches durch eine Suspension mit kleinen Schleifpartikeln gebildet ist. Bei einer entsprechend schnellen Bewegung der Bearbeitungskugel 1 wird das Schleiffluid aufgrund der Trägheit weitestgehend nicht durch die Reibungskraft zwischen der Innenfläche der Bearbeitungskugel 1 und dem Schleiffluid mitbewegt, sodass eine Relativbewegung zwischen der Bearbeitungskugel 1 und somit dem darin angeordneten, zu bearbeitenden Bauteil und dem Schleiffluid erzeugt wird. Durch die in dem Schleiffluid enthaltenen Schleifpartikel kommt es zu einer Reibung an den Oberflächen des Bauteils und zu einem entsprechenden Abtrag an den Oberflächen des Bauteils, die sich relativ zum Schleiffluid bewegen. Durch eine Anordnung des Bauteils in der Bearbeitungskugel 1, bei der das Bauteil relativ zur Bearbeitungskugel 1 Bewegungsfreiheitsgrade aufweist, kann eingestellt werden, in welchen Bewegungsrichtungen eine Relativbewegung des Bauteils zum Fluid stattfindet und in welchem das Bauteil gegenüber dem Fluid weitgehend ortsfest ist und eine Relativbewegung zur Bearbeitungskugel ausführt. Allerdings ist vorzugsweise eine komplett ortsfeste Anordnung des zu bearbeitenden Bauteils in der Bearbeitungskugel gegeben, da die bewegungsrichtungsabhängige Bearbeitung der Bauteiloberflächen auch durch eine entsprechende Einstellung der Bewegung der Bearbeitungskugel 1 möglich ist.In the
Die Bewegung der Bearbeitungskugel 1 erfolgt angepasst an das zu bearbeitende Bauteil und die zu bearbeitende Oberflächen des Bauteils. Insbesondere können unterschiedliche Bewegungen miteinander überlagert werden, um komplexe Bewegungen zu realisieren. Beispielsweise können Bewegungen um zwei unabhängige Drehachsen miteinander überlagert werden, um taumelnde Bewegungen der Bearbeitungskugel 1 und des zu bearbeitenden Bauteils zu verwirklichen. Die Bewegung wird dabei üblicherweise oszillierend ausgeführt, als in einer Hin- oder Herbewegung, um die entsprechenden Trägheitsmomente des Schleiffluids auszunutzen.The movement of the
