    摘要: L'invention concerne un procédé de détourage d'une lentille ophtalmique (10) en vue de son montage dans un entourage mixte d'une monture de lunettes qui présente au moins une arcade, comportant :
    a) une étape d'acquisition d'un profil longitudinal caractérisant la forme souhaitée du contour de la lentille,
    b) une étape de délimitation du profil longitudinal en un premier arc associé à l'arcade et un second arc, au cours de laquelle on acquiert les positions de deux points singuliers du profil longitudinal caractérisant les positions des deux extrémités de l'arcade,
    c) une première étape de finition de la lentille ophtalmique, au cours de laquelle on ramène une première partie de son contour à la forme du premier arc,
    d) une seconde étape de finition de la lentille ophtalmique, au cours de laquelle on ramène une seconde partie de son contour à la forme du second arc.

    Selon l'invention, à l'étape b), on corrige la position d'au moins l'un des deux points singuliers acquis de manière à réduire la longueur du premier arc du profil longitudinal.

    摘要: In a conventional normal control machining method, reciprocating operation control of an X-axis table and reciprocating operation control of a Y-axis table are intertwined with each other to complicate control of both tables. A sophisticated control method and a high-performance controller for operating it are thereby required when a toric surface for correcting intensive astigmatism having a significant level difference is ground or cut. In the method for machining an aspheric surface, a workpiece rotating about a rotational axis and a rotary tool (214) movable relatively to the workpiece in the direction of the rotational axis of the workpiece and in the direction orthogonal to the rotational axis are provided, wherein the rotary tool (214) machines the workpiece into an axis-asymmetric aspheric surface by moving in a specified direction at a specified feed pitch in the partial or entire region extending from the center of the rotational axis of the workpiece to the outer circumferential part of the workpiece in the direction orthogonal to the rotational axis of the workpiece.

    摘要: 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.
