摘要： Optical surfaces with complex geometry are produced today by grinding, polishing or casting in a prefabricated negative mould. This has the disadvantage that all geometric moulds required for production must be kept on stock. The object of the invention is to disclose a process that allows these optical surfaces and moulding shells to be directly manufactured in a single step according to inddividual data. For that purpose, a blank for machining an optical surface or a blank of a moulding shell for manufacturing optical surfaces 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 means of a turning tool which can move relative to the blank (in the X axis). The turning tool can move 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. This process is particularly suitable for directly manufacturing plastic lenses and moulding shells for producing plastic lenses, for example progressive lenses.
