Polishing method

Abstract

A surface to be polished having a plurality of portions of significantly different curvatures can be polished evenly by the use of resilient abrasive members by selecting at least two resilient abrasive members from resilient abrasive members having a plurality of dome-shaped portions of different curvatures determined by the plurality of curvatures of the polishing target, and mounting the selected resilient abrasive members to specific abrasive member mounting jigs and polishing the surface of the polishing target.

1 . A polishing method using resilient abrasive members each having a dome-shaped portion, the resilient abrasive members being of a plurality of types having dome-shaped portions of different curvatures, comprising the steps of: 
 selecting more than two of the resilient abrasive members according to the surface shape of the surface to be polished; and    polishing the surface to be polished by the use of the selected resilient abrasive members, and    wherein the step of selecting comprises selecting a resilient abrasive member having the dome-shaped portion of curvature close to the largest curvature of the surface to be polished, a resilient abrasive member having the dome-shaped portion of a curvature close to the smallest curvature of the surface to be polished, and a resilient abrasive member having the dome-shaped portion of curvature close to the average curvature between the largest curvature and the smallest curvature of the surface to be polished.
