LASER ASSISTED SURFACE FINISHING APPARATUS AND METHOD

摘要

A method and an apparatus for finishing a component (250) includes at least one articulating arm having a shot peening apparatus (262) and at least one laser source (212). A plurality of laser redirectors (112) are configured to redirect a laser originating from the laser source. Each laser redirector in the plurality of laser redirectors is mounted to a first rail and a second rail. A controller (130) is controllably coupled to the articulating arm and each of the rails such that output signals from the controller control a position of the articulating arm, and a position of each laser redirector in the plurality of laser redirectors. The laser generates a local soft area (254) across an area of a surface (252) of the component and the area is then shot peened to achieve a shot peened finish.
