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.

Automatic process planning for robotic deburring operations

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.

Integral part wear indicator system, method and apparatus

An optical height gauge including a housing, a mounting bar coupled to, and maintained partially in, the housing, a mounting bracket connected to the mounting bar, the mounting bracket including at least one light source holder, a camera mount connected to the mounting bracket, and a tilt bar connected to the mounting bracket and contacting the mounting bar.

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.

Method of removing a coating

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.
