Abstract: A system for detecting an edge of a substrate, comprising a coated assembly. The coated assembly includes a conductive substrate having at least one edge portion and a dielectric coating coupled along the conductive substrate, the dielectric coating covering the at least one edge portion of the conductive substrate. The system also includes a conductive tool configured to interact with the coated assembly and a substrate sensing system. The substrate sensing system includes a power source coupled with the conductive tool, the coated assembly, and an electrical circuit including the power source and the coated assembly and a sensor configured to sense a change between an open configuration and a closed configuration of the electrical circuit. In an open configuration the conductive tool is engaged with the coated assembly and disengaged from the conductive substrate and in a closed configuration the conductive tool is engaged with the conductive substrate.

Abstract: A robotic deburring process that automatically, accurately, and efficiently removes burrs from a workpiece. The robotic deburring process uses CAM location data to establish deburring trajectory, physics based machining models to predict burr type and size, and force control functions to compensate inaccuracies due of inaccuracies of robots arms.

Abstract: A part comprising a one or more removable wear indicators is provided. The part may be a stator segment comprising a plurality of airfoils. The stator segment may also comprise one or more mock airfoils at each end of the stator segment. Each of the mock airfoils may comprise an indicator configured to wear during a polishing process.

Abstract: A method for machining and inspecting a workpiece includes steps of: supporting the workpiece with a workpiece support; moving a machining tool relative to the workpiece with a tool positioning system, and machining a workpiece feature into the workpiece with the machining tool as a function of reference geometry data; moving a measuring device relative to the workpiece with a measuring device positioning system that is independent of the tool positioning system, and mapping a geometry of the workpiece feature with the measuring tool to provide workpiece geometry data indicative thereof; and processing the workpiece geometry data and the reference geometry data with a processor to compare the geometry of the workpiece feature to a reference geometry.

Abstract: A method of removing at least a part of a thermal sprayed wear resistant coating on a gas turbine engine part includes grinding the thermal sprayed wear resistant coating with a superabrasive grinding wheel.

Abstract: A method for removing a predetermined amount of material from the inner surface of a circular article which deviates from a true circular configuration. The outer surface of the article is touch probed to determine its true location in space, and the data are stored in a computer memory. These data are then compared to engineering design data to establish the location of the surface to which material removal is desired. A control computer compares the measured data with the design data, and sends commands to the machine control system, causing the machine to remove the excess material down to the desired dimension. Any deviations from circular are compensated for by moving the article radially relative to the cutting tool as the article moves circumferentially relative to the cutting tool.
