METHOD FOR AUTONOMOUSLY INCREASING DIMENSIONAL ACCURACY OF A WORKPIECE VIA THREE-DIMENSIONAL SANDING
A method includes, during a processing cycle: navigating the sanding head across a region of a workpiece according to a toolpath; and, based on a sequence of force values output by a force sensor coupled to the sanding head, deviating the sanding head from the toolpath to maintain forces of the sand...

| description | A method includes, during a processing cycle: navigating the sanding head across a region of a workpiece according to a toolpath; and, based on a sequence of force values output by a force sensor coupled to the sanding head, deviating the sanding head from the toolpath to maintain forces of the sanding head on the workpiece region proximal a target force. The method also includes: detecting a sequence of positions of the sanding head traversing the workpiece region; interpreting a surface contour in the workpiece region based on the sequence of positions; detecting a difference between the surface contour and a corresponding target surface defined in a target model of the workpiece; generating a second toolpath for the workpiece region based on the difference; and, during a second processing cycle, navigating the sanding head across the workpiece region according to the second toolpath to reduce the difference. |
