Abstract: A method for processing a mortise of a small-size superalloy turbine disk using laser shock peening A laser shock peening (LSP) parameter of a laser shock peening (LSP) robot is designed. A spatial data of a motion trajectory of the LSP robot for a laser shock peening area of mortise teeth of the first mortise is found and recorded using a robot simulation system software to generate a trajectory program of the robot for the first mortise. Then a rotation program of an end of an arm of the LSP robot is written according to an included angle between two adjacent mortises to generate a trajectory program of the robot for all mortises of the turbine disk. Finally, the turbine disk is processed by laser shock peening.

Abstract: A robotic laser-guiding device for laser shock peening includes a laser-guiding arm, a reflecting mirror and a manipulator. The laser-guiding arm includes a laser entry tube, a laser-guiding tube, a laser exit tube and a laser shock head sequentially connected. The laser entry tube is rotatably connected to the laser-guiding tube through a joint. The laser-guiding tube is rotatably connected to the laser exit tube through a joint. The laser entry tube is connected to a laser generator. Each joint is provided with the reflecting mirror. The laser emitted by the laser generator passes through the laser entry tube, one reflecting mirror, the laser-guiding tube, another reflecting mirror, the laser exit tube and the laser shock head to irradiate a part, so as to perform the laser shock peening.
