1. An adaptive repair method comprising:
- providing a digitized model of a base portion of a physical component;
aligning a corresponding base portion of a nominal CAD model of the physical component with the digitized model of the base portion of the physical component such that the nominal CAD model extends beyond the digitized model of the base portion of the physical component used for alignment;
extracting a set of co-ordinate points from the nominal CAD model once aligned;
lofting a cross-sectional profile based on a measured profile of the base portion along a path defined by the co-ordinate points of the nominal CAD model once aligned to the digitized model of the base portion of the physical component to create an adapted model for repair of the physical component; and
adding material to the physical component based on the adapted model as part of adaptively repairing the physical component.

Abstract
This disclosure concerns an adaptive repair method, for example for aerofoil blade components. The method generates a digitized model of a physical component and uses data from the digitized model to align a part of the physical component with a nominal CAD model of the component. A combination of the digitized data and data from the nominal CAD model are then used to create an adapted model for repair of the component.

13. An adaptive repair method comprising:
-
providing a component, a digitized model of a portion of the component, and an adapted model; and adding material to the component based on the adapted model as part of adaptively repairing the component, wherein the adapted model is provided by; aligning a corresponding portion of a nominal CAD model of the component with the digitized model of the base portion of the component such that the nominal CAD model extends beyond the digitized model of the portion of the component, extracting a set of co-ordinate points from the aligned nominal CAD model, and lofting a cross-sectional profile based on a measured profile of the portion along a path defined by the co-ordinate points of the aligned nominal CAD model to create the adapted model for repair of the component. - View Dependent Claims (14, 15, 16)
