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

A tool comprising a plurality of wear indicators is provided. The tool may be made from a rapid prototyping process. The tool may be used in an abrasive processing operation. The tool may comprise one or more control elements, (e.g., control geometries, part interfaces, fixture interfaces and/or the like). These control elements may comprise indicators of tool wear. The indicators may be inspected physically (e.g., by touch) and/or visually.

Abrasive tool indicator system, method and apparatus

A fixture assembly includes an inner diameter wall displaced from a main body by a first end wall with a convex surface and a second end wall with a concave surface. A method of machining a gas turbine engine component with an Abrasive Flow Media (AFM) process includes restricting a flow of media adjacent to an outer sidewall of an outer airfoil to be generally equal between each of a multiple of airfoils of the component.

Abrasive flow media fixture with end contour

An upper shield and a lower shield may be coupled to a rotor for polishing airfoils of the rotor in a vibratory bowl. The upper shield and the lower shield may include spars. The spars may correspond to leading edges and trailing edges of the airfoils. A media including abrasive particles may be flowed through the rotor in the vibratory bowl. The spars may protect the leading edges and trailing edges of the airfoils from excessive material removal by the abrasive particles.

System and method for polishing airfoils

A fixture assembly includes a frame with a tip rail displaced from a main body. A method of polishing a gas turbine engine component includes restricting a flow of media adjacent to a tip of a component with an airfoil to be generally equal to a flow of media adjacent to a sidewall of the airfoil.

Vibratory mass media fixture with tip protector

A tool for use during the abrasive flow polishing of an airfoil cluster in an abrasive flow machine is described. The tool may comprise a body and prongs extending from the body. Each prong of the tool may be configured to insert between an adjacent pair of airfoils of the airfoil cluster to create at least one channel therebetween. The channel may allow the flow of an abrasive media therethrough.
