Japanese Patent JP3938213

Kind Code:

B2

Abstract:

The present invention is a process by which optical surfaces of lenses, particularly plastic progressive lenses and molding shells for producing lenses are manufactured directly in a single step according to didicidual data. A blank from which an optical surface or a molding shell is to be manufactured is held at the workpiece carrier of a spindle axis (Z axis) of a shaping machine and is directly turned into its final form by a turning tool which can move relative to the blank (in the X axis), i.e., transversely to the direction of displacement of the tool. During each rotation of the spindle, the turning tool is incrementally adjusted towards or away from the blank depending on the characteristic surface data, which may be predetermined or calculated on-line.
