Abstract:
1. A method of using machining to repair a component workpiece, from a known and undamaged profile of the component, the method comprising: acquiring coordinates of points on an envelope of the component workpiece, the set of points forming a cluster of points; comparing the known and undamaged profile with the cluster of points in order to define zones on the component workpiece that have excess or insufficient thickness; deforming the profile using a morphing method so that the deformed profile interpolates the cluster of points, the deformation of the profile using a morphing function, and machining the component workpiece using a machine tool parameterized on the basis of the morphing function, wherein the deforming of the profile involves wherein the expert-defined EDC deformation parameters comprise coordinates of at least one control point to be displaced on the mesh portion simulating the known and undamaged profile, and at least one displacement vector for the at least one control point to displace to deform the mesh portion and to reduce differences between the mesh portion and previously measured points simulating points of the cluster of points obtained from a damaged workpiece other than the component workpiece.
