Processe and system for preparing a vehicle surface (e.g., an aircraft fuselage) for painting include a preparation booth (100) which is sized and configured to house the vehicle (F). At least one robotic assembly (200a, 200b) is reciprocally movable within the preparation booth (100) relative to a longitudinal axis of the vehicle (F), and is provided with a robotic hand (230) having at least one abrasive disc (242a) attached to an attachment pad (242) of the robotic hand (230), and at least one nozzle (252a, 252b, 252c) for discharging a stream of rinse fluid. Operation of the at least one robotic assembly (230) will cause the at least one abrasive disc (242a) of the robot hand (230) to abrade the surface of the vehicle (F). The robotic hand (230) may thereafter be maneuvered so that the at least one nozzle (252a, 252b, 252c) is directed toward the abraded vehicle surface (F). A stream of rinse fluid may then be discharged through the at least one nozzle (252a, 252b, 252c) and towards the abraded surface of the vehicle (F) so as to rinse the abraded surface of particulate matter.

A component according to the disclosure may include a body having an aperture therein for receiving one of a turbomachine shaft or a lathe chuck, wherein in response to the body being coupled to the lathe chuck, the aperture is oriented substantially axially relative to an axis of rotation of the body with the lathe chuck; and a flange coupled to and in direct axial contact with the body, the flange including a surface that extends axially relative to the axis of rotation of the body, wherein the surface of the flange comprises a matingly engageable face configured to contact an axially aligned surface during operation of the component and having a sanding indentation thereon, wherein a surface roughness of the surface of the flange is less than a surface roughness of a remainder of the component.

An end effector for a robotic sanding system includes a sanding head including a sander configured to sand a surface of a workpiece. A motor is operatively coupled to the sander. The motor is configured to rotate the sander to sand the surface of the workpiece. The motor includes a first central longitudinal axis. A coupler is configured to removably secure the end effector to an attachment interface of an arm of the robotic sanding system. The coupler includes a second central longitudinal axis. The first central longitudinal axis is offset from the second central longitudinal axis. One or more sensors are coupled to the sanding head. The one or more sensors are configured to detect presence of a metal within the predefined range.

A disc-shaped polishing pad (1) is used for a polishing method of the present invention. The polishing pad (1) has a peripheral surface (111) on a polishing surface (10) side in an axial direction of the disc of a tapered surface whose diameter is reduced to the polishing surface (10). An angle formed by the peripheral surface (111) and the polishing surface (10) is 125° or more and less than 180°. The polishing pad (1) has a hardness immediately after a pressing surface is in close contact of 40 or more by a testing method specified in an appendix 2 of JIS K7312: 1996, “Spring Hardness Test Type C Testing Method”. A slurry containing abrasives is supplied to a polished surface larger than the polishing surface (10). The polishing surface (10) is pressed against the polished surface and the polishing pad (1) is moved to polish the polished surface.
