ABSTRACT:
A method and apparatus for producing a controlled tapered cut on a curved surface in preparation for repairing a damaged area on the surface. The apparatus includes a cutting tool which is revolved around the damaged area at incrementally smaller radii until the entire damaged area and the periphery thereof has been machined. The cutting tool is maintained in a position such that the surface of the workpiece is machined along a tapered plane which is disposed at a predetermined angle with respect to the tangent to the surface of the workpiece. As the normal to the workpiece surface changes its angular orientation, the position of the cutting tool is correspondingly adjusted to machine the workpiece. The cutting tool is disposed in a channel member extending normal to the surface in such a manner that the angular position thereof can be adjusted. The channel member is connected to a pivot shaft utilizing cables and torque rods such that the channel member and the cutting tool can be revolved by the pivot shaft around the damaged area. The resulting machined surface is tapered, allowing the workpiece to be repaired utilizing composite materials consisting of a plurality of plies which are bonded to one another.
