Description

Technisches GebietTechnical area

Die vorliegende Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff von Anspruch 1 und ein Verfahren gemäß dem Oberbegriff von Anspruch 9.The present invention relates to a device according to the preamble of claim 1 and a method according to the preamble of claim 9.

Stand der TechnikState of the art

Plattenförmige Werkstücke aus Holz oder Holzwerkstoffen werden u.a. in der Möbel- und Bauelementeindustrie verarbeitet. An den Schmalseiten solcher Werkstücke wird dabei häufig ein Kantenmaterial angebracht, dass in einem aufgebrachten Zustand in vielen Fällen eine Nachbearbeitung erfordert. Toleranzen des Kantenmaterials und/oder der Werkstückgeometrie, aufspannungsbedingte Lagetoleranzen des Werkstücks oder ein unterschiedliches Verhalten je nach Werkstück- bzw. Bearbeitungsposition bei der Nachbearbeitung erfordern dabei häufig zum Erzielen guter Bearbeitungsqualitäten einen Ausgleich durch eine Tasteinrichtung, mit der das Nachbearbeitungswerkzeug relativ zum Werkstück geführt wird.Plate-shaped workpieces made of wood or wood-based materials are u.a. processed in the furniture and component industry. An edge material is often attached to the narrow sides of such workpieces, which in many cases requires reworking in an applied state. Tolerances of the edge material and / or the workpiece geometry, stress-related position tolerances of the workpiece or a different behavior depending on the workpiece or processing position in the post-processing often require to achieve good processing qualities compensation by a sensing device with which the post-processing tool is guided relative to the workpiece.

Solch eine Tasteinrichtung weist beispielsweise eine Tastrolle auf. Die Tastrolle kann in ihrem Durchmesser verstellbar sein, wie aus der EP 2 539 096 A1 bekannt. Alternativ kann die Tasteinrichtung auch in Form einer Tastkurve ausgebildet sein. In beiden Fällen wird die Tasteinrichtung während der Werkstückbearbeitung mit einer bestimmten Tastkraft an das Werkstück angedrückt, um so über einen dauerhaften Kontakt eine Relativpositionierung von Werkzeug und Werkstück festzulegen.Such a sensing device has, for example, a sensing roller. The sensing roller can be adjustable in diameter, as from the EP 2 539 096 A1 known. Alternatively, the sensing device may be formed in the form of a Tastkurve. In both cases, the sensing device during workpiece machining with a pressed specific force to the workpiece so as to set a permanent contact relative positioning of the tool and workpiece.

Diese aus dem Stand der Technik bekannten Vorrichtungen weisen jedoch insbesondere bei der Bearbeitung wechselnder Werkstückformen und/oder -materialien, z.B. im Rahmen einer Losgröße-1 Fertigung, keine befriedigenden Bearbeitungsergebnisse auf.However, these prior art devices are particularly useful in the machining of changing workpiece shapes and / or materials, e.g. in the context of a batch size-1 production, no satisfactory processing results.

Darstellung der ErfindungPresentation of the invention

Der vorliegenden Erfindung lag daher als technisches Problem zugrunde, eine Vorrichtung zur Bearbeitung eines plattenförmigen Werkstücks, das bevorzugt zumindest abschnittsweise aus Holz, Holzwerkstoffen, Kunststoff oder dergleichen ausgebildet ist, mit einer eingangs genannten Tasteinrichtung bereitzustellen, die auch bei Bestückung mit sehr unterschiedlichen Werkstücken eine hochqualitative Bearbeitung ermöglicht.The present invention was therefore based on a technical problem to provide a device for processing a plate-shaped workpiece, which is preferably at least partially made of wood, wood materials, plastic or the like, with an aforementioned sensing device, which is a high quality even when equipped with very different workpieces Editing possible.

Der Erfindung liegt der Gedanke zu Grunde, dass bei den Vorrichtungen im Stand der Technik Eigenschaften des zu bearbeitenden Werkstücks, wie Material und Abmessungen, nicht berücksichtigt werden. Unabhängig vom Werkstück wird die Tasteinrichtung mit einer konstanten Tastkraft an das Werkstück angedrückt und an diesem entlang geführt.The invention is based on the idea that in the devices in the prior art properties of the workpiece to be machined, such as material and dimensions, are not taken into account. Regardless of the workpiece, the sensing device is pressed against the workpiece with a constant force and guided along this.

Unterschiedliche Werkstücke weisen jedoch verschiedene Eigenschaften, beispielsweise verschiedene Nachgiebigkeiten auf. Unter einer Nachgiebigkeit eines Werkstücks wird erfindungsgemäß die Verformung des Werkstücks an einer Position bei einer bestimmten Krafteinwirkung, insbesondere in Krafteinwirkungsrichtung, verstanden. Die Nachgiebigkeit kann ein positionsabhängiger Parameter sein. In anderen Worten kann die Nachgiebigkeit eines Werkstücks über das Werkstück hinweg bzw. entlang des Werkstücks variieren. Wird eine Tasteinrichtung mit einer bestimmten Kraft an ein Werkstück angedrückt, hängt die Werkstücknachgiebigkeit beispielsweise von Material und Form des Werkstücks sowie der Andrückposition ab. Genauer gesagt können Werkstücke mit denselben Abmessungen jedoch aus unterschiedlichen Materialien an derselben Position verschiedene Nachgiebigkeiten aufweisen. Auch können Werkstücke aus denselben Materialien jedoch mit verschiedenen Abmessungen unterschiedliche Nachgiebigkeiten aufweisen.However, different workpieces have different properties, for example, different compliances. A compliance of a workpiece according to the invention is understood to mean the deformation of the workpiece at a position with a specific force, in particular in the direction of action of force. The compliance can be a position-dependent parameter. In other words, the compliance of a workpiece may vary across the workpiece or along the workpiece. Becomes a sensing device pressed with a certain force to a workpiece, the workpiece compliance depends, for example, on the material and shape of the workpiece and the pressure position. More specifically, however, workpieces having the same dimensions but having different materials at the same position may have different compliances. Also, workpieces made of the same materials but with different dimensions may have different compliances.

Werden derartige Unterschiede in den Nachgiebigkeiten zwischen verschiedenen Werkstücken bei der Festlegung der Tastkraft der Tasteinrichtung nicht berücksichtigt, resultiert dies in Ungenauigkeiten in der Zustellung von Werkzeug zu Werkstück. Dies wiederum führt zu Einbußen in der Bearbeitungsqualität.If such differences in the compliances between different workpieces are not taken into account in determining the force of the sensing device, this results in inaccuracies in the delivery of tool to workpiece. This in turn leads to losses in the processing quality.

Diese Erkenntnis macht sich die vorliegende Erfindung zu Nutze und stellt eine Vorrichtung zum Bearbeiten eines plattenförmigen Werkstücks, das bevorzugt zumindest abschnittsweise aus Holz, Holzwerkstoffen, Kunststoff oder dergleichen ausgebildet ist, mit einer Bearbeitungseinrichtung zum Bearbeiten des Werkstücks, einer Fördereinrichtung zum Herbeiführen einer Relativbewegung zwischen der Bearbeitungseinrichtung und dem Werkstück, und einer Tasteinrichtung zum Führen der Bearbeitungseinrichtung entlang des Werkstücks insbesondere derart, dass eine konstante Relativpositionierung von Bearbeitungseinrichtung und einem sich in Bearbeitung befindenden Werkstückabschnitt erzielbar ist, bereit. Die Vorrichtung ist eingerichtet, die Tasteinrichtung mit einer Tastkraft an das Werkstück anzudrücken. Gekennzeichnet ist die Vorrichtung dabei dadurch, dass sie eine Eigenschaftserfassungseinrichtung zum Erfassen einer Eigenschaft des zu bearbeitenden Werkstücks aufweist. Mit dieser Eigenschaftserfassungseinrichtung lassen sich eine Eigenschaft, wie Abmessung, Material und/oder Nachgiebigkeit, des zu bearbeitenden Werkstücks erfassen. Es ist auch denkbar, dass hier das Erfassen mehrerer Eigenschaften des Werkstücks möglich ist. Die Vorrichtung ist ferner eingerichtet, die Tastkraft der Tasteinrichtung und/oder die Zustellungspositionierung der Bearbeitungseinrichtung zum Werkstück an die erfasste Werkstückeigenschaft bzw. die erfassten Werkstückeigenschaften anzupassen. Unter einer Einrichtung der Vorrichtung wird erfindungsgemäß eine Herrichtung der Vorrichtung derart verstanden, dass die Vorrichtung ohne weitere Modifikationen den entsprechenden Schritt ausführen kann. In anderen Worten ist die erfindungsgemäße Vorrichtung derart hergerichtet, dass diese die Tastkraft der Tasteinrichtung und/oder die Zustellpositionierung der Bearbeitungseinrichtung zum Werkstück an die erfasste Werkstückeigenschaft anpassen kann, ohne das weitere Modifikationen der Vorrichtung erforderlich sind.This knowledge makes use of the present invention and provides a device for processing a plate-shaped workpiece, which is preferably at least partially made of wood, wood materials, plastic or the like, with a processing device for processing the workpiece, a conveyor for bringing about a relative movement between the Machining device and the workpiece, and a sensing device for guiding the machining device along the workpiece, in particular such that a constant relative positioning of the machining device and a workpiece section being processed is achievable ready. The device is adapted to press the sensing device with a force to the workpiece. The device is characterized in that it has a property detection device for detecting a property of the workpiece to be machined. With this property detecting device, a property such as size, material and / or compliance of the workpiece to be processed can be detected. It It is also conceivable that the detection of several properties of the workpiece is possible here. The device is further configured to adapt the sensing force of the sensing device and / or the positioning position of the processing device to the workpiece to the detected workpiece property or the detected workpiece properties. A device of the device according to the invention means a device of the device such that the device can carry out the corresponding step without further modifications. In other words, the device according to the invention is prepared in such a way that it can adapt the sensing force of the sensing device and / or the positioning position of the processing device to the workpiece to the detected workpiece property, without further modifications of the device are required.

Mit der vorliegenden Erfindung kann demnach die Tastkraft der Tasteinrichtung und/oder die Zustellpositionierung der Bearbeitungseinrichtung zum Werkstück an mindestens eine Eigenschaft des zu bearbeitenden Werkstücks angepasst werden. Hierdurch lässt sich vorteilhafterweise die Genauigkeit der Zustellung von Werkzeug zu Werkstück auch bei der Bearbeitung verschiedener Werkstücke erhöhen, was in einer besseren Bearbeitungsqualität resultiert. So ist beispielsweise eine hohe Bearbeitungsgüte auch bei einer Losgröße-1 Fertigung erzielbar.Accordingly, with the present invention, the sensing force of the sensing device and / or the positioning position of the processing device to the workpiece can be adapted to at least one property of the workpiece to be machined. This advantageously makes it possible to increase the accuracy of the tool-to-workpiece infeed even when machining different workpieces, which results in better machining quality. For example, a high processing quality can be achieved even with a lot size-1 production.

Bevorzugt ist die Eigenschaftserfassungseinrichtung in Förderrichtung vor der Bearbeitungseinrichtung vorgesehen. Dies ermöglicht es, die Werkstückeigenschaft vor der Bearbeitung zu ermitteln und sogleich in die anschließende Bearbeitung des Werkstücks einfließen zu lassen. Besonders gute Bearbeitungsqualitäten sind das Ergebnis.Preferably, the property detection device is provided in the conveying direction before the processing device. This makes it possible to determine the workpiece property before machining and to allow it to be incorporated immediately into the subsequent machining of the workpiece. Particularly good machining qualities are the result.

Insbesondere ist die Eigenschaftserfassungseinrichtung eingerichtet, die Eigenschaft des Werkstücks entlang einer Strecke zu erfassen. In anderen Worten wird die Eigenschaft des Werkstücks nicht nur punktuell, sondern kontinuierlich entlang eines Streckenzugs, z.B. entlang einer Werkstückseite ermittelt. So wird ein Datensatz aus einer Vielzahl von Positionen entlang der Strecke und der zur jeweiligen Position gehörenden Werkstückeigenschaft generiert. Die Vorrichtung ist gemäß dieser bevorzugten Ausführungsform ferner eingerichtet, die Tastkraft der Tasteinrichtung an die erfasste Eigenschaft an der jeweiligen Position entlang dieser Strecke anzupassen. Diese Anpassung erfolgt bevorzugt während der Bearbeitung des Werkstücks. In anderen Worten kann in dieser bevorzugten Ausführungsform die Tastkraft der Tasteinrichtung beim Führen der Bearbeitungseinrichtung entlang des Werkstücks kontinuierlich an die erfasste Werkstückeigenschaft an der jeweiligen Werkstückposition angepasst werden. Besonders bevorzugt ist die Vorrichtung eingerichtet, die Eigenschaft entlang der Stirnseiten und Deckseiten des plattenförmigen Werkstücks zu ermitteln. Gemäß diesen bevorzugten Ausführungsformen ist eine besonders hohe Bearbeitungsqualität erzielbar, da positionsabhängige Unterschiede in der Werkstückeigenschaft bei der Einstellung der Tastkraft der Tasteinrichtung berücksichtigt werden können.In particular, the property detection device is set up, the property of the workpiece along a Track to capture. In other words, the property of the workpiece is determined not only punctually, but continuously along a path train, for example along a workpiece side. Thus, a data set is generated from a multiplicity of positions along the route and the workpiece property belonging to the respective position. The device according to this preferred embodiment is further adapted to adjust the sensing force of the sensing device to the detected characteristic at the respective position along that route. This adaptation preferably takes place during the machining of the workpiece. In other words, in this preferred embodiment, the tactile force of the sensing device when guiding the machining device along the workpiece can be continuously adjusted to the detected workpiece property at the respective workpiece position. Particularly preferably, the device is set up to determine the property along the end faces and cover sides of the plate-shaped workpiece. According to these preferred embodiments, a particularly high machining quality can be achieved, since position-dependent differences in the workpiece property can be taken into account when setting the sensing force of the sensing device.

Die erfasste Eigenschaft kann eine Nachgiebigkeit des Werkstücks sein. Die Nachgiebigkeit eines Werkstücks ist, wie oben beschrieben, die Verformung des Werkstücks bei einer bestimmten Krafteinwirkung. Auch anderen Eigenschaften sind hier denkbar, wie die Dichte, Druckfestigkeit etc.The detected property may be a compliance of the workpiece. The compliance of a workpiece is, as described above, the deformation of the workpiece at a certain force. Other properties are also conceivable here, such as the density, compressive strength, etc.

In einer bevorzugten Ausführungsform erfolgt die Erfassung der Eigenschaft des Werkstücks durch die Eigenschaftserfassungseinrichtung mit Werkstückberührung. Soll als Eigenschaft die Nachgiebigkeit des Werkstücks erfasst werden, kann die Eigenschaftserfassungseinrichtung hierzu eine Kraftaufbringungseinrichtung zum Beaufschlagen des Werkstücks mit einer vorbestimmten Kraft und eine Messeinrichtung aufweisen, mit der die Nachgiebigkeit des Werkstücks bei der Beaufschlagung mit der vorbestimmten Kraft ermittelbar ist. Mit diesen bevorzugten Ausführungsformen ist eine besonders kostengünstige und genaue Eigenschaftserfassung des Werkstücks möglich.In a preferred embodiment, the detection of the property of the workpiece by the property detection device with workpiece contact takes place. If the yield of the workpiece is to be detected as a property, the characteristic detection device can for this purpose be a force application device for applying a predetermined force to the workpiece and a Have measuring means with which the compliance of the workpiece in the application of the predetermined force can be determined. With these preferred embodiments, a particularly cost-effective and accurate property detection of the workpiece is possible.

Alternativ kann die Eigenschaft des Werkstücks durch die Eigenschaftserfassungseinrichtung ohne Werkstückberührung erfassbar sein. Diese bevorzugte Ausgestaltung führt zu besonders hohen Bearbeitungsqualitäten, da eine Werkstückbeschädigung durch die Eigenschaftserfassungseinrichtung aufgrund von mechanischem Kontakt verhindert werden kann.Alternatively, the property of the workpiece can be detected by the property detecting device without workpiece contact. This preferred embodiment leads to particularly high machining qualities, since workpiece damage can be prevented by the property detection device due to mechanical contact.

In einer weiteren Zielrichtung betrifft die vorliegende Erfindung ein Verfahren zum Bearbeiten eines plattenförmigen Werkstücks, das bevorzugt zumindest abschnittsweise aus Holz, Holzwerkstoffen, Kunststoff oder dergleichen ausgebildet ist, insbesondere unter Verwendung einer Vorrichtung nach einer der zuvor beschriebenen Ausführungsformen. Das Verfahren umfasst das Erfassen einer Eigenschaft des zu bearbeitenden Werkstücks mit einer Eigenschaftserfassungseinrichtung, und das Führen einer Bearbeitungseinrichtung entlang des Werkstücks mit einer Tasteinrichtung, wobei die Tasteinrichtung mit einer Tastkraft an das Werkstück angedrückt wird. Gekennzeichnet ist das Verfahren dadurch, dass die Tastkraft und/oder die Zustellpositionierung der Bearbeitungseinrichtung zum Werkstück an die erfasste Eigenschaft des zu bearbeitenden Werkstücks angepasst wird. Hinsichtlich der Vorteile des Verfahrens wird auf die Vorteile verwiesen, die zuvor in Verbindung mit den Ausführungsformen der erfindungsgemäßen Vorrichtung dargelegt wurden.In a further aspect, the present invention relates to a method for processing a plate-shaped workpiece, which is preferably at least partially made of wood, wood materials, plastic or the like, in particular using a device according to one of the embodiments described above. The method comprises detecting a property of the workpiece to be machined with a property detection device, and guiding a machining device along the workpiece with a sensing device, wherein the sensing device is pressed against the workpiece with a sensing force.

A combination of continuous and stationary technology is conceivable within the scope of the present invention.

Darüber hinaus weist die Vorrichtung 10 gemäß der vorliegenden bevorzugten Ausführungsform eine Eigenschaftserfassungseinrichtung 13 zum Erfassen einer Eigenschaft des Werkstücks 1 auf. Die Eigenschaftserfassungseinrichtung 13 ist bevorzugt in Förderrichtung F vor der Bearbeitungseinrichtung 11 vorgesehen. Alternativ kann sie auch in der Bearbeitungseinrichtung 11 umfasst oder in Förderrichtung F nach der Bearbeitungseinrichtung 11 angeordnet sein.Moreover, the device 10 according to the present preferred embodiment has a property detecting device 13 for detecting a property of the workpiece 1. The feature detection device 13 is preferably in Delivery direction F before the processing device 11 is provided. Alternatively, it may also be included in the processing device 11 or arranged downstream of the processing device 11 in the conveying direction F.

Insbesondere kann die Eigenschaftserfassungseinrichtung 13 eingerichtet sein, eine Nachgiebigkeit des Werkstücks 1 zu erfassen. Bevorzugt ist die Einrichtung 13 eingerichtet, die Nachgiebigkeit des Werkstücks 1 entlang aller 4 Stirnseiten 2, 2' und beider Deckseiten 3 des plattenförmigen Werkstücks 1 zu ermitteln. Unter einer Erfassung einer Eigenschaft entlang einer Werkstückseite wird erfindungsgemäß die kontinuierliche Ermittlung dieser Eigenschaft von einem Bereich der Werkstückseite bis zu einem anderen Bereich der Werkstückseite verstanden. In anderen Worten wird ein Verlauf der entsprechenden Eigenschaft, beispielsweise der Nachgiebigkeit, entlang der Werkstückseite durch die Eigenschaftserfassungseinrichtung 13 detektiert.In particular, the property detection device 13 may be configured to detect a compliance of the workpiece 1. Preferably, the device 13 is set up to determine the compliance of the workpiece 1 along all 4 end faces 2, 2 'and both top sides 3 of the plate-shaped workpiece 1. A detection of a property along a workpiece side is understood according to the invention to be the continuous determination of this property from one region of the workpiece side to another region of the workpiece side. In other words, a course of the corresponding property, for example, compliance, along the workpiece side is detected by the property detection device 13.

Zur Ermittlung der Nachgiebigkeit kann die Einrichtung 13 eine nicht gezeigte Kraftaufbringungseinrichtung und eine Messeinrichtung aufweisen. Mit der Kraftaufbringungseinrichtung kann die Eigenschaftserfassungseinrichtung 13 das Werkstück 1 mit einer vorbestimmten Kraft beaufschlagen, wobei mittels der Messeinrichtung die Nachgiebigkeit des Werkstücks bei Beaufschlagung mit der vorbestimmten Kraft ermittelt wird. Die Messeinrichtung kann beispielsweise ausgebildet sein, eine Nachgiebigkeit berührungslos, insbesondere optisch, und besonders bevorzugt mittels Laser zu bestimmen. Auch andere Ausgestaltungen sind hier denkbar. Die Kraftaufbringungseinrichtung kann eine Tastkurve aufweisen. Die vorbestimmte Kraft, mit welcher das Werkstück beaufschlagt wird, kann beispielsweise zwischen 100 und 200 N, bevorzugt bei etwa 150 N liegen. Je nach Werkstückeigenschaft kann die Tastkraft auch geringer sein.To determine the compliance, the device 13 may have a force application device, not shown, and a measuring device. With the force application device, the property detection device 13 can act on the workpiece 1 with a predetermined force, wherein by means of the measuring device, the compliance of the workpiece is determined upon application of the predetermined force. By way of example, the measuring device can be designed to determine compliance without contact, in particular optically, and particularly preferably by means of a laser. Other embodiments are conceivable here. The force application device may have a Tastkurve. The predetermined force, which is applied to the workpiece, for example, between 100 and 200 N, preferably at about 150 N lie. Depending on the workpiece property, the sensing force may also be lower.

Die Eigenschaftserfassungseinrichtung 13 kann ferner eingerichtet sein, eine maximale Kraft zu ermitteln, mit der das Werkstück 1 beaufschlagt werden kann, damit die Nachgiebigkeit einen bestimmten Grenzwert, beispielsweise 0,01 mm, nicht überschreitet. Hierbei kann iterativ die Kraft, mit welcher das Werkstück beaufschlagt wird, erhöht bzw. verringert, bis die durch die Messeinrichtung ermittelte Nachgiebigkeit im angestrebten Bereich liegt. So kann beispielsweise ein Verlauf von maximalen Tastkräften entlang einer Werkstückseite ermittelt werden, mit dem die Nachgiebigkeiten entlang dieser Werkstückseite einen bestimmten Grenzwert nicht überschreiten.The characteristic detection device 13 can also be set up to determine a maximum force with which the workpiece 1 can be acted upon, so that the compliance does not exceed a specific limit value, for example 0.01 mm. Here, iteratively, the force with which the workpiece is applied, increased or decreased until the determined by the measuring device compliance is within the desired range. For example, it is possible to determine a progression of maximum probing forces along a side of the workpiece with which the compliances along this side of the workpiece do not exceed a certain limit.

Darüber hinaus umfasst die Vorrichtung 10 eine nicht gezeigte Tasteinrichtung. Die Tasteinrichtung kann in Form einer Tastrolle und/oder Tastkurve ausgebildet sein. Auch andere Ausgestaltungen sind hier denkbar. Die Tasteinrichtung ist vorgesehen, um die Bearbeitungseinrichtung 11 entlang des Werkstücks 1 zu führen, sodass eine vorbestimmte Zustellpositionierung zwischen Bearbeitungseinrichtung und Werkstück 1 erzielbar ist. Hierfür wird die Tasteinrichtung mit einem bestimmten Tastdruck an die zu bearbeitende Seite des Werkstücks 1 angedrückt. Erfindungsgemäß ist die Vorrichtung 10 dabei eingerichtet, den Tastdruck der Tasteinrichtung und/oder die Zustellpositionierung der Bearbeitungseinrichtung zum Werkstück an die durch die Eigenschaftserfassungseinrichtung 13 erfasste Eigenschaft bzw. die erfassten Eigenschaften des Werkstücks 1 anzupassen. In anderen Worten kann beispielsweise der Tastdruck der Tasteinrichtung in Abhängigkeit der in der Eigenschaftserfassungseinrichtung 13 ermittelten Werkstückeigenschaften derart angepasst werden, dass eine maximale Nachgiebigkeit des Werkstücks nicht überschritten wird. Ebenso ist es im Rahmen dieser bevorzugten Ausführungsform denkbar, dass die Zustellpositionierung von Bearbeitungseinrichtung zum Werkstück an die ermittelten Werkstückeigenschaften angepasst wird. Bevorzugt wird die Tastkraft und/oder die Zustellpositionierung kontinuierlich während der Werkstückbearbeitung entlang einer Werkstückseite angepasst.In addition, the device 10 comprises a sensing device, not shown. The sensing device may be in the form of a touch roller and / or Tastkurve. Other embodiments are conceivable here. The sensing device is provided to guide the processing device 11 along the workpiece 1, so that a predetermined Zustellpositionierung between processing device and workpiece 1 can be achieved. For this purpose, the sensing device is pressed with a certain tactile pressure to the side of the workpiece 1 to be machined. According to the invention, the device 10 is set up to adapt the tactile pressure of the sensing device and / or the positioning position of the processing device to the workpiece to the property or the detected properties of the workpiece 1 detected by the property detection device 13. In other words, for example, the tactile pressure of the sensing device can be adjusted in dependence on the workpiece properties determined in the property detection device 13 such that a maximum compliance of the workpiece is not exceeded. Likewise, within the scope of this preferred embodiment, it is conceivable that the delivery positioning of the processing device to the workpiece is adapted to the determined workpiece properties. Preferably, the Touching force and / or the delivery positioning continuously adjusted during workpiece machining along a workpiece side.
