The invention discloses a stator blade finish forging automatic machining method. The method adopts a self-adaption machining technology, and blade deviation, torsion, profile surface tolerance and machining consistency are ensured. The method is simple in machining procedure, computer control and management are adopted, controlled devices completely automatically finish the sequential operation,the degree of automatic operation is improved, multiple devices, multiple passes of procedures, repeated clamping and repeated standard conversion for original stator blade machining are reduced intotwo passes of procedures of machining, two times of clamping and one time of standard conversion on one kind of equipment, labor is saved, the production period of parts is shortened, and the production efficiency is improved.
