Abstract
Method and apparatus (10) for finishing a workpiece surface using magnetorheological fluid (16) wherein the workpiece (26) is positioned near a carrier surface (14) such that a converging gap (22) is defined between the workpiece surface and the carrier surface (14); a magnetic field is applied at the gap (22); a flow of magnetorheological fluid (16) is introduced into the gap (22) creatign a work zone in the fluid (16) to form a transient finishing tool for engaging and causing material removal at the workpiece surface.
