Abstract
A method of using machining to repair a component workpiece, such as a turbomachine blade, from a known profile of the component, is disclosed. The method includes deforming the profile using a morphing method so that the deformed profile interpolates a cluster of points measured on the component. Deforming the profile involves comparing each zone of the component workpiece that has excess or insufficient thickness with elementary deformation configurations (EDCs) each in the form of a mesh portion and of points, the elementary deformation configurations (EDCs) being filed in a database, the database associating the parameters of the morphing function with each elementary deformation configuration (EDC).
