Abstract:
An arrangement providing superior flexibility of use and time- and cost-effectiveness includes a robot which holds a tool and a display. A user views the display and manipulates the tool through communication with the robot. Methods of using the arrangement involve user reliance on visual data on the display to determine which way to instruct the robot to manipulate the tool.
Abstract:
On a machine tool, a program (12) receives data from a scanning or analogue probe P, measuring a feature of a workpiece W. This data is combined with assumed machine position data during the scanning movement. This avoids having to break into the servo feedback loop (24) to get actual measured machine position data. The assumed machine position data can be derived from a part program (20) which controls the scanning movement. Several ways are described for compensating for errors between the assumed machine position values and the actual values.
Abstract:
Gegenstand der Erfindung ist eine Vorrichtung zum Verbessern von Genauigkeitseigenschaften von Handhabungsgeräten, wie einem Mehrachsen- Industrieroboter, mit einem Handhabungsgerät (1 ), wenigstens einer Steuereinrichtung (11 ) zum Bewegen des Handhabungsgerätes (1 ), einer Messeinrichtung (6), welche von der Handhabungseinrichtung (1 ) unabhängig oder unmittelbar auf der Handhabungseinrichtung (1 ) positioniert ist, einer Auswerteeinrichtung (10) für die von der Messeinrichtung (6) generierten Messsignale und einer Referenzfläche (13) oder Messplatte (4) mit einem oder mehreren Markern (5) oder Löchern an einem anzusteuernden Werkzeug oder einer Einrichtung (3). Eine Verbesserung der Genauigkeitseigenschaften wird erreicht, indem die Marker (5) oder Löcher von lochartigen Vertiefungen (15) in der Referenzfläche (13) oder der Messplatte (4) in Form von Sacklöchern (16) oder Schlitzen (12) mit einer bestimmten Tiefe und mit einem bestimmten Sacklochdurchmesser oder einer bestimmten Schlitzbreite gebildet sind, wobei das Verhältnis von Tiefe zu Sacklochdurchmesser oder Schlitzbreite größer als 1 ist.
Abstract:
A laser projection system, intelligent data correction system and method which corrects for differences between the as-built condition and the as- designed condition of a workpiece which includes determining the as-built condition of a workpiece with a digitizer scanner and modifying data of the as-built condition or the data of a laser projection based upon the data received from the digitizer scanner of the as-built condition. A preferred intelligent data correction system includes metrology receivers fixed relative to the digitizer scanner and the workpiece and a metrology transmitter to determine the precise location and orientation of the digitizer scanner relative to the workpiece.
Abstract:
The present invention provides systems and methods for orienting or assembling a detailed part in a predetermined orientation in which the detailed part is made up of a plurality of component parts. First, a location and alignment are defined by a virtual assembly tool. Next, a unique combination of self-locating features are disposed on the individual component parts in which the unique combination corresponds to the location and alignment defined by the virtual assembly tool. Thus, the virtual assembly tool is integrated into the assembled detailed part. In practice the individual component parts are engaged with predetermined corresponding components parts using the self-locating features. The act of engaging the individual component parts is repeated until all component parts are engaged with each respective corresponding component parts.
Abstract:
Bei einem Verfahren zur Ermittlung einer von einer Soll-Lage (Sa-c) abweichenden Toleranzlage (T a-c ) eines Aufnahmepunktes (6) eines in einer Anlage (2) ruhenden, von einem Transportmittel (8) aufzunehmenden Objektes (4a-c) : - wird am Objekt (4a-c) eine Kennmarke (14a-c) in einer bekannten Relativposition (R a-c ) zum Aufnahmepunkt (6) angebracht, - ermittelt eine Recheneinrichtung (18) anhand einer in der Anlage (2) angeordneten Ortungsvorrichtung (16) eine Raumlage (L a-c ) der Kennmarke (14a-c) in der Anlage (2), - ermittelt die Recheneinrichtung (18) die Toleranzlage (T a-c ) aus der Raumlage (L a-c ) und der Relativposition (R). Eine entsprechende Vorrichtung enthält eine entsprechende Kennmarke (14a-c) und eine entsprechende Recheneinrichtung (18).
Abstract:
A method and system for providing control that include providing a workpiece that includes a target shape, providing a cutting tool, providing a 3-D image associated with the workpiece, identifying the target shape within the workpiece image, providing a 3-D image associated with the cutting tool, registering the workpiece with the workpiece image, registering the cutting tool with the cutting tool image, tracking at least one of the workpiece and the cutting tool, transforming the tracking data based on image coordinates to determine a relationship between the workpiece and the cutting tool, and, based on the relationship, providing a control to the cutting tool. In one embodiment, the workpiece image can be represented as volume pixels (voxels) that can be classified and/or reclassified based on target shape, waste, and/or workpiece.
Abstract:
In order to register a robot, the operative parts of the robot are placed in a first condition. An image acquiring arrangement carried by the robot is directed towards an item, and the image of that item is acquired and stored. Subsequently the component parts of the robot are moved so that the image acquiring arrangement can acquire a second different image of the item. The process is repeated to acquire data comprising a plurality of images and, for each image data concerning the position of the component parts of the robot when the image was acquired.
