Abstract

Disclosed is a method and apparatus for polishing an edge of an article involving providing at least one carrier including: first and second opposing surfaces defining a groove, the first and second opposing surfaces being spaced apart in a first direction to receive the edge; and magnetic field generator configured to provide a magnetic field in the groove to stiffen magnetorheological (MR) fluid disposed in the groove to provide at least one polishing zone; receiving the edge in the polishing zone; and driving relative motion between the at least one carrier and the edge in a second direction substantially transverse to the first direction.
