Abstract
A method is disclosed for reconditioning blades for turbo-machinery that have a material deficiency resulting from wear and tear, damage, or dimensions that are smaller than specified, in which material is removed, at least from parts of the blade, and is replaced with new material. The actual geometry of the blade is measured at certain specific points and is stored. The desired geometry, or the desired profile in its desired position, is determined via data processing technology. The desired geometry is compared with the actual geometry, and in cases of significant deviations in position, is adjusted to coincide with the actual geometry. The adjusted desired geometry is mathematically reduced by a defined amount of coating to be removed. The calculated net geometry is actually produced via the removal of material, at least over part of the blade, and new material is applied to the finished net geometry, until the desired profile is achieved.
