Method for machining the trailing edge of a turbine engine blade

The present invention relates to a method for manufacturing a turbine engine blade, the blade comprising an airfoil and the profile of the airfoil being defined by a theoretical digital model, including the manufacture of a blank having a thickened portion along the trailing edge of the airfoil relative to the theoretical profile, characterized in that said thickened portion is removed by adaptive machining, including the following steps: positioning the blank in a reference frame; acquiring, by probing at a predetermined number of points (Ni) on a first surface of the blank along the trailing edge, the position of said points in the reference frame; determining the differences, in one direction, in the delta position (Ni) from corresponding points of the theoretical model; producing machining grids on said surface of the blank, the peaks of the grids being determined from said points (Ni); determining the amount of material to be removed from the surface of the grids, said amount being based on the position
