Abstract (en)
[origin: WO0153038A1] A method and system for the manufacture of ophthalmic lenses comprising a computer (102) and a CNC machining platform (104) in operative connection with the computer. The CNC machining platform includes a mounting stage (110), a block (106) in releasable connection with the mounting stage, and a machining tool (112). When an unfinished lens blank (108) is properly mounted on the block, the computer is operative to direct the CNC machining platform to perform both back surface generation and patternless edging of the lens blank in one machining cycle. The computer is further operative to direct the CNC machining platform to machine a lap tool for each lens and machine a block for receiving each lens. The block is machined by the platform to include scribe lines for facilitating proper alignment of lens blank.
