Abstract:
A method for repairing a component having first and second major surfaces, a thickness between the major surfaces, and an edge, is characterized by utilizing a template to determine if the component is suitable for repair, and forming a slot cut entirely through the thickness of the component. The slot extends inward from the edge of the component, has an open end at the edge of the component, a closed end within the component, a width, a radius at the closed end, and chamfered edges at the open end. Forming the slot includes forming an initial cut with a first cutting surface from the edge of the component at least to the defect, finishing the initial cut to the width and the radius with a second cutting surface, resulting in a finished cut, and chamfering the edge of the finished cut with a third cutting surface.
