    Abstract: A method of tuning the contact pressure across an abrasive disc is presented. The method includes coupling the abrasive disc to a backup pad comprising a pressure tuning feature that causes an experienced pressure by a worksurface, across a radius of the abrasive disc, to be uniform. The method also includes abrading a worksurface by contacting the abrasive disc to the worksurface. The backup pad causes the abrasive disc to have a cut rate that is substantially uniform across the surface of the abrasive disc when compared to the abrasive disc on a backup pad with no pressure tuning feature.

    Abstract: An imaging and repair system (100) is presented that includes a first imaging system (110) configured to image and detect a defect on a worksurface. The first imaging system comprises a first camera configured to capture a plurality of first images of the worksurface. The plurality of first images are stored in a data source. The system also includes a second imaging system (110) configured to image and characterize an orange peel of the worksurface in an area proximate the defect. Characterizing the worksurface comprises identifying a delta value of orange peel. The system also includes a defect repair processor configured to select a repair strategy based on a defect type. The system also includes a defect modifier configured to modify the selected repair strategy based on the orange peel characterization of the worksurface. The system also includes a defect repair tool (120) configured to automatically effect the modified repair strategy.

    Abstract: A disc changing system for a robotic defect repair system is presented. The system has a first abrasive disc and a second abrasive disc. The first and second abrasive discs are coupled to a liner. The system includes an abrasive disc placement device configured to automatically: remove the first abrasive disc from the liner, transport the first abrasive disc to a robotic tool of the robotic defect repair system, and place the first abrasive disc on a backup pad coupled to the robotic tool. The system also includes an abrasive disc remover configured to automatically remove the first abrasive disc after receiving a removal signal. The system also includes a controller configured to send an instruction to the disc placement device to remove, transport and place the first abrasive disc, instruct the robotic tool to conduct an abrasive operation. The controller is also configured to send the removal signal. The controller is a processor and the instructions are stored on a non-transitory computer-readable medium and executed by the processor.

    Abstract: A defect detection and ranking system for a vehicle assembly line is provided. The system includes an image capture device that captures a plurality of images of a vehicle on the vehicle assembly line. The system also includes a defect detector that analyzes the plurality of captured images and, based on the analysis, detects a plurality of defects on the surface of the vehicle. Each of the plurality of defects has an associated x-y-z coordinate location, a defect type, and a defect severity. The system also includes a datastore containing a vehicle specification, for the vehicle on the vehicle assembly line, and a defect priority based on the vehicle specification. The system also includes a defect prioritization generator configured to: receive the plurality of defects from the defect detector, retrieve the vehicle specification and the defect priority, and apply the defect priority to the plurality of defects, and output a prioritized list of defects, wherein the prioritized list of defects. The defect prioritization generator outputs the prioritized list of defects to an output device associated with the vehicle assembly line.
