An apparatus for inspecting a turbine blade tip shroud includes a frame comprising a top surface and a bottom surface that is alignable with the turbine blade tip shroud, and, at least one z-notch inspection slot that passes through the frame from the top surface to the bottom surface and is positioned to align with at least one z-notch of the turbine blade tip shroud when the frame is aligned on the turbine blade tip shroud. The apparatus further includes a removable z-notch inspection insert comprising a cross-sectional profile substantially matching the at least one z-notch inspection slot and comprising a z-notch guide face that faces the z-notch of the turbine blade tip shroud when the removable z-notch inspection insert is passed through the z-notch inspection slot

A modification process and modified article are disclosed. The modification process includes locating an area in an article, removing the area by machining to form a machined region, inserting a modification material into the machined region, securing the modification material to the article, machining the modification material flush with a geometry of the article, and applying a coating over at least a portion of the article. Another modification process includes locating an area under a suction side leading edge tip shroud fillet of an airfoil, removing the area by machining to form a hole, inserting a modification material having improved material properties as compared to an original base material into the hole, securing the modification material in place, machining the modification material and the airfoil to form a new fillet contour, and applying a coating over at least a portion of the airfoil. Also disclosed is the modified article.

A system for use in removing a multi-layer coating from a substrate is provided. The multi-layer coating includes a first coating applied to the substrate and a second coating applied over the first coating. The first coating is formed from a first material and the second coating is formed from a second material different from the first material. The system includes a grinding mechanism configured to remove the multi-layer coating from the substrate, and a controller coupled in communication with the grinding mechanism. The controller is configured to position the grinding mechanism against the multi-layer coating, initiate a first removal mode that directs the grinding mechanism to traverse across the substrate, monitor a variable operating parameter of the grinding mechanism during the first removal mode, and evaluate a value of the variable operating parameter against a predetermined threshold to determine whether the second coating has been removed from the substrate.

A fixture and method for adjusting a workpiece are disclosed. The fixture includes a holding device engageable to a workpiece to secure the workpiece, and an adjustment device engageable to a projecting member of the workpiece and movable along a first axis and a second axis. Movement of the adjustment device along the first axis when engaged to the projecting member adjusts the projecting member along the first axis, and movement of the adjustment device along the second axis when engaged to the projecting member adjusts the projecting member along the second axis.

A method of replacing a wind turbine blade includes suspending the wind turbine blade from support hub of a wind turbine, connecting one or more cable climbing members between the support hub and the wind turbine blade, and lowering the one or more cable climbing members and the wind turbine blade from the support hub.

Method and system for replacing a single wind turbine blade

A method for dimensionally inspecting a component of a gas turbine system is provided. The method includes disposing the component on a fixture for stabilizing the component. Also included is probing a first datum location of the component with a coordinate measurement machine for establishing a first datum point. Further included is probing at least one location of the component with the coordinate measurement machine to determine at least one measurement relative to the first datum point. Yet further included is displaying the at least one measurement in an output report.
