Polishing method

Abstract

A surface to be polished having a plurality of surfaces of significantly different curvatures can be polished evenly by the use of resilient abrasive members by using a polishing method including the steps of selecting at least two resilient abrasive members 10 a , 10 b from the resilient abrasive members having a plurality of dome-shaped portions of different curvatures determined by a plurality of curvatures on the surface to be polished of the polishing target, and mounting the selected resilient abrasive members 10 a , 10 b to specific abrasive member mounting jigs 20 a , 20 b and polishing the surface to be polished of the polishing target L 2.

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 the 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 resilient abrasion members having the dome-shaped portions of curvatures close to the average curvature of the respective divisions of the surface to be polished of a plurality of curvatures, which are divided according to the curvature ranging from the largest curvature to the smallest curvature.
