摘要

Roughness is a crucial factor that determines workpiece quality. In this paper, the time-domain signals of polishing force for polishing an aero-engine blade with an abrasive cloth wheel were experimentally obtained, and the contact arc lengths were determined based on these signals. A mathematical model for the representative R_a of blade surface roughness after polishing was then established, and this model is only related to the contact arc length. This model was experimentally verified, and the prediction results agree well with the measurement results.
