Title:
LENS-PROCESSING CONTROLLER, LENS-PROCESSING CONTROL PROGRAM, METHOD FOR EVALUATING LENS SHAPE, AND METHOD FOR MANUFACTURING SPECTACLE LENS
Document Type and Number:
WIPO Patent Application WO/2014/156800
Kind Code:
A1
Abstract:
A lens-processing controller provided with: an anticipated-shape-specifying means (201b) for determining the anticipated finished shape of a bevel cross-section, taking into account the amount of processing tool interference experienced when an unprocessed spectacle lens is beveled; a state-of-contact-specifying means (210c) for determining the state in which a measuring element of a lens-shape measuring gauge (251) makes contact with the bevel of a spectacle lens having the anticipated finished shape; a theoretical-shape-specifying means (210d) for adopting, as the theoretical shape of a beveled spectacle lens rim, the shape-measurement result to be obtained by the lens-shape measuring gauge (251) when the state of contact is to be reflected; and a shape-comparing means (250c) for comparing the theoretical shape and the actual shape actually obtained using the lens-shape measuring gauge (251) on the beveled spectacle lens rim, and evaluating the actual shape on the basis of the results.
