Abstract
A method for correcting the processing path of a robot-guided tool for processing at least one component, wherein: a target position for a plurality of points of a target processing path is specified; from the specified points, points to be corrected are selected; the actual position for the selected points to be corrected is measured or detected on at least one component to be processed; and the processing path corresponding to the measured or detected actual position of the points of the component to be processed is correspondingly corrected. The method is suitable, for example, for welding a component into a borehole using a laser beam, wherein the processing path of the laser beam is corrected so as to correspond to the contour of the component.
Claims13
A method for processing at least one component with a robot-guided tool, the method comprising:
- specifying respective target positions for a plurality of points of a processing path;
- selecting points to be corrected from among the specified points, wherein the number of the selected points to be corrected is less than the number of the plurality of points of the processing path;
- determining a respective actual position for the selected points on at least one component to be processed;
- correcting only the selected points of the processing path based on the determined actual positions;
- and
- controlling the robot-guided tool to traverse the processing path on the basis of the determined actual positions.
A system with a robot-guided tool for processing at least one component, wherein the system is configured to:
- specify respective target positions for a plurality of points of a processing path;
- select points to be corrected from among the specified points, wherein the number of the selected points to be corrected is less than the number of the plurality of points of the processing path;
- determine a respective actual position for the selected points on at least one component to be processed;
- correct only the selected points of the processing path based on the determined actual positions;
- and
- control the robot-guided tool to traverse the processing path on the basis of the determined actual positions.
A computer program product including program code stored on a non-transitory computer-readable medium, the program code configured to, when executed on a computer, cause the computer to:
- specify respective target positions for a plurality of points of a processing path;
- select points to be corrected from among the specified points, wherein the number of the selected points to be corrected is less than the number of the plurality of points of the processing path;
- determine a respective actual position for the selected points on at least one component to be processed;
- correct only the selected points of the processing path based on the determined actual positions;
- and
- control a robot-guided tool to traverse the processing path on the basis of the determined actual positions.
