Title:
LENS MACHINING SYSTEM, MACHINING SIZE MANAGEMENT DEVICE, MACHINING SIZE MANAGEMENT METHOD AND METHOD FOR MANUFACTURING SPECTACLE LENS
Document Type and Number:
WIPO Patent Application WO/2014/080738
Kind Code:
A1
Abstract:
A lens machining system (4) according to the present invention comprises: a lens shape machining device (9) for machining a spectacle lens in accordance with three-dimensional machining trace data acquired by computing lens shape data; a three-dimensional perimeter measurement device (10) for measuring the perimeter of a spectacle lens that was machined into a lens shape by the lens shape machining device (9); and a machining size management device (7, 8) which corrects a computation parameter used for the computation of the machining track data on the basis of the difference in perimeter between an actually measured perimeter acquired by the three-dimensional perimeter measurement device (10) and a theoretical perimeter acquired by computation.
