  • Method of determining shape data
    Publication number: 20050106998
    Abstract: A reference template is used to help in the reconstruction of a damaged workpiece, such as a turbine blade. The reference template is a copy of the workpiece from before it was used. The reference template is scanned in layers, including the portion corresponding to that which has been damaged in the workpiece, as well as adjacent undamaged portions. The adjacent undamaged portions of the workpiece are also scanned as layers. Profiles of the layers of the reference template and workpiece are generated, based on the scans. Sets of offsets are then determined based on corresponding points within adjacent scanned layers in the undamaged portion of the workpiece and the corresponding portion of the reference template and also within the portion of the reference template corresponding to the damaged portion of the workpiece.
