  • a second zone on the exterior of the component is polished using the robotic polishing device according to a second polishing process.
  • An operating parameter for the robotic polishing device is maintained during the first polishing process and the second polishing process, but different between the first polishing process and the second polishing process.
  • the first operating parameter may be a first pressure exerted by the robotic polishing device against the bladed rotor.
  • the second operating parameter may be a second pressure exerted by the robotic polishing device against the bladed rotor.
  • the first operating parameter may be a first tool path speed of the robotic polishing device along the exterior of the bladed rotor.
  • the second operating parameter may be a second tool path speed of the robotic polishing device along the exterior of the bladed rotor.
  • each of the first zones may be polished before polishing any of the second zones.

  • Each rotor blade 26 extends longitudinally along a camber line of the respective rotor blade 26 between a leading edge 36 of the respective rotor blade 26 to a trailing edge 38 of the respective rotor blade 26. Referring to FIGS. 1 and 2 , each rotor blade 26 extends laterally across a thickness of the respective rotor blade 26 between opposing sides 40 and 42 of the respective rotor blade 26; e.g., pressure and suction sides of the respective rotor blade 26.
  • FIG. 5 is a schematic illustration of an exemplary system 44 for polishing the bladed rotor 20.
  • This polishing system 44 includes an automated robotic polishing device 46 and a controller 48 for automating operation of the robotic polishing device 46.
  • the controller 48 is generally described below as a single unit / system.
  • the controller 48 may alternatively be implemented by a plurality of discrete controllers operated together.
  • the controller 48 for example, may implement or may be separated into a robot controller and a programmable logic controller (PLC), with an HMI software that directs a polishing sequence.
  • PLC programmable logic controller
  • FIG. 7 illustrates the idler rollers 64A and 64B (generally referred to as "64") for another set of different polishing device heads 52 for the robotic polishing device 46.
  • These idler rollers 64 are provided with different configurations in order to change a contact patch between the abrasive polishing belt 60 and the bladed rotor 20 (not visible in FIG. 7 ).
  • An outer surface 82A of the idler roller 64A may have a straight or substantially straight (e.g., slightly conical, curved, etc.) sectional geometry when viewed, for example, in a reference plane parallel with (e.g., that includes) the rotational axis 74 of the idler rotor 64A.
