Claim 0:
1. A method of machining a surface of a component, the method comprising:
scanning the surface of the component to obtain scanned electronic 3D data representing the scanned surface of the component;
locating a surface defect of the scanned surface and identifying a defect region that surrounds and includes the surface defect;
providing electronic 3D data representing a patch having the desired shape of the defect region and comprising a plurality of nodes;
transforming the patch to generate a tooling path for repairing the surface defect, transforming the patch comprising translating the plurality of nodes of the patch, the translation distance of each node being based on the distance of that node from an origin node of the patch;
determining a weighting for each node using a two-dimensional Gaussian function, the weighting indicative of a translation distance of that node relative to the translation distance of the origin node; and
machining the surface of the component according to the generated tooling path.
