Repair of a shrouded blade

A method of repairing a shrouded blade of a gas turbine engine comprising:

• determining a datum plane from which to measure deflections of the shrouded blade;
• determining spatial position for a plurality of hardface surfaces of a shroud for the blade;
• determining a displacement of the hardface surfaces for each shroud in a set of blades utilizing a mean, mode, or median displacement for the hardface surfaces of a set of shrouded turbine blades;
• determining a cross shroud dimension for the shrouded blade;
• removing material from one or more of the hardface surfaces of the shrouded blade;
• adding material to one or more hardface surfaces of the shrouded blade;
• machining a first side hardface surface to a desired dimension based on the displacement of the hardface surfaces;
• and
• machining a second side hardface surface such that the distance between the first side hardface and second side hardface corresponds to approximately the cross shroud dimension.
