Abstract:
An axially rotating circular polishing pad is conditioned by a rotating end effector that has an abrasion disc in contact with a polishing surface of the pad. The end effector moves along a radius of the polishing pad surface at a velocity that varies to compensate for locations on the polishing pad surface having linear velocities that are directly related to their respective radii. A desired contact force is maintained between the end effector and the polishing pad surface.
