Claim 15:
16. A method for repairing a composite structure, the method comprising:
defining a rework zone on the composite structure;
selecting a scarf repair model based on a maximum longitudinal distance between two extremities of the composite structure and an aspect ratio of the rework zone, wherein the aspect ratio of the rework zone is a ratio of a width of a longitudinal edge of the rework zone and the maximum longitudinal distance between the two extremities of the composite structure;
separating the rework zone into sections;
identifying a theoretical scarfing bottom surface for each of the sections of the rework zone from a model of the composite structure;
measuring reference locations in each of the sections of the rework zone;
identifying an actual scarfing bottom surface for each of the sections of the rework zone based on measurements collected at the reference locations;
modifying parameters for a rework program for an automated scarfing tool based on deviations between the measurements collected at the reference locations; and
removing plies in each of the sections of the rework zone using the automated scarfing tool.
