| WO 2008046408 A2 UPAB: 20080604 NOVELTY - The method involves guiding a tool (2) or an object e.g. mechanical workpiece, by a handling device e.g. industrial robot, to form a kinematic chain. An actuator (3) is located between a robot hand (1) of the kinematic chain and the tool or object. A sensor (5) i.e. complementary MOS camera, is used to detect a relative movement between the object and tool or the robot hand. A deviation of an actual movement path of the tool, the object or the robot hand to a target movement path is counteracted by maintaining the tool or the object with the actuator. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a device for fine-positioning of a tool during machining an object. USE - Method for fine-positioning of a tool during handling of an object e.g. mechanical workpiece and patient, by an automatic handling device e.g. industrial robot, bend-arm robot and gantry robot, of a robot system that is utilized for robotically-guided milling, arc welding, laser cutting and hand-operated processing. ADVANTAGE - The method obtains high path and position accuracy of the tool at the object during handling the object. The method facilitates the use of the robots in the simple robot system that exhibits path accuracy for applications requiring high precision in guiding the tool. DE 102006049627 A1 UPAB: 20080519 NOVELTY - The method involves guiding a tool or an object by a handling device, which has multiple axis of movement for approximate positioning of the tool or the object. The object forms a kinematic chain, and has an actuator (3) arranged between an end member of the kinematic chain and the tool or the object, which has a higher actuating accuracy in a dimension or axis than the other axis of movement. A fine-positioning of the tool or the object results, while a relative motion between the object and the tool or end member of the kinematic chain is detected with a sensor (5). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a device for fine-positioning of a tool while machining an object. USE - Method for fine-positioning of a tool while machining an object. ADVANTAGE - The object forms a kinematic chain, and has an actuator arranged between an end member of the kinematic chain and the tool or the object, which has a higher actuating accuracy in a dimension or axis than the other axis of movement, and hence enables to increase the positioning accuracy of the tool or object guidance. | |||||||
