Abstract: A system is disclosed including a three-dimensional object having a non-conforming region, and a photogrammetry device adapted to scan the three-dimensional object. The system further includes optical reference targets and a controller structured to perform functions of repairing the three-dimensional object. The controller commands the photogrammetry device to scan the three-dimensional object, and calculates a nominal surface location and contour for the three-dimensional object. The controller further commands the photogrammetry device to scan the non-conforming region of the three-dimensional object, and calculates a material removal tool path comprising a path adapted to remove material from the object located beyond the nominal surface location and contour. The controller generates a solid model of the damaged region of the object based on the nominal surface location and contour, and computes a material addition tool path according to the solid model.

Abstract: A system is disclosed for depositing mate-rial on a component. The system includes a deposition de-vice operatively coupled to a fiber optic Nd: YAG laser. The deposition device includes a focusing prism that focuses the Nd:YAG laser at a focal area on a bladed disk, where the fo-cal area on the bladed disk is between two blades of the disk. The system further includes an imaging means that views the focal area of the component. The imaging means and the fiber optic Nd:YAG laser each are positioned in a sub-stantially similar optical relationship to the focal area on the bladed disk. The system further includes an additive material delivery means that delivers additive material to the compo-nent at the focal area on the component.

Abstract: A system and method for repairing a hollow fan blade. In one aspect the blade includes a hollow portion having a plug disposed therein, wherein the plug is smaller than the open-ing. During processing the blade is located under a vacuum box and the gap is sealed between the plug and the opening using a fiber laser.

Abstract: An apparatus includes a prism mount that retains a prism. The mount inclu des a ledge that engages a first side of the prism, a support surface struct ured that engages a second side of the prism, a retaining member that slidab ly engages a third side of the prism, and a biasing member that biases the r etaining member to an engaged position with the prism. The mount further inc ludes a slot disposed between the ledge and the support surface. The retaini ng member includes a machine screw, and a nut confines the biasing member be tween the nut and a prism mount body. The biasing member is retained in a co unterbore in the prism mount body, and an end of the machine screw protrudes from the counterbore. The prism mount body further includes an alignment sl ot at a fixed azimuthal angle, and the laser deposition device includes a pr otrusion that engages the alignment slot.
