Method for cutting optical lens and/or molding die therefor

摘要

A cutting method for cutting an optical lens and/or a molding die therefor includes rotating the optical lens and/or the molding die about the optical axis, moving a cutting blade in a direction perpendicular to an optical axis to cut the optical lens and the molding die, and varying the feed pitch of the cutting blade in the direction perpendicular to the optical axis in accordance with the position of the optical lens and/or the molding die in the radial direction.
