POLISHING METHOD FOR CURVED SURFACE

摘要: PROBLEM TO BE SOLVED: To provide a polishing method which produces excellent optical components and forming dies by suppressing the generation of stepwise machining error. SOLUTION: After uniformly workpiece (step S101), shape is measured S102). If there some error with respect to desired shape, an correcting process carried out S103) so as eliminate error, then expecting S104) taking account be produced on outside peripheral edge portion workpiece, The range from within twice longitudinal length contact surface spherical polisher workpiece. has been finished, S106), are repeated until achieved.
