On Fly Laser Balancing by Melting and Displacing Material

A method is described for balancing a rotating part by partial melting a designated area of the part by a laser beam and radially displacing the melted material by means of a gas stream.

A rotating part 1 to be balanced is coupled to a mechanism to determine the location of a mass needed to balance the part. A laser beam 2 is directed through an opening in a suitable housing 3 to impinge on the designated balancing location on the part to selectively melt a small area of the part at the balance location. A jet of gas moving concentric to the laser beam overcomes the centrifugal force and displaces the molten material radially inward. The movement of the displaced material 4 reduces the moment of inertia and changes the balance. This method can be used in work areas in which restrictions on particle content in the environment are present, and also in work areas in which access to the part is not convenient.
