Abstract

A method of honing, polishing, reducing, or otherwise abrading, workpiece surfaces utilizing a visco-elastic abrasive medium in situ between the workpiece and a displacer. Said displacer member having surfaces in a facing spaced relationship to the surfaces of said workpiece to be abraded to thereby form a media chamber between the surfaces of said workpiece to be machined and said displacer member. The visco-elastic abrasive medium is deposited within said media chamber.
Thereafter, one or more forms of relative motion between the workpiece and displacer forces flow of the medium across the workpiece surface to be abraded thereby effecting the abrasion as desired.
