Disclosed is method of processing an aspheric-surface, using a cutting apparatus including at least one turning tool (324, 325) movable relative to a work (10) that is rotatable about its rotating axis, in the same direction as the rotating axis of the work (10) and in a direction perpendicular to the rotating axis of the work (10). The method includes the step of moving the turning tool (324, 325) at a predetermined feed pitch in a fixed direction over at least a part of the entire region of the work (10) extending from the center of the rotating axis of the work (10) to a peripheral portion of the work (10) in another direction perpendicular to the rotating axis of the work (10) in order to process the work (10) for forming an axis-asymmetric aspheric surface. <IMAGE> |
