Abstract:
1. A method of restoring a composite structure containing an out-of-tolerance area, comprising: determining the location of a first out-of-tolerance area within the structure, said determining comprising internally scanning said structure with a non-destructive scanner to map internal areas of the structure including moving a scanner over a surface of the structure; identifying a boundary for the first out-of-tolerance area; calculating a volume of the structure to be removed based on the boundary of the first out-of-tolerance area, said calculating comprising calculating a portion of material to be removed that includes the first out-of-tolerance areas, said calculating comprising using a scarf angle to be formed at the periphery of said volume; programming a machine tool to remove the calculated volume; removing the calculated volume using the programmed machine tool to form an exposed surface; scanning the exposed surface of the composite structure to determine a location of a second out-of-tolerance area; and, replacing the volume of the structure removed by the machine tool.
