Abstract: A laser cutting tool whose position, aiming direction and cutting duration are controlled by a programmable microprocessor, is housed in a cabinet above a platen equipped with a number of component-holding stations. Each of the stations has a plurality of vises sized to grasp an eyeglass component including lenses or lens blanks, a eyeglass frame, temple pieces, a nose bridge, a carrying case or a lens cleaning swatches. Program data sets specify the edging out of blanks of a particular optical property, and the engraving of the lens and other components with decorative patterns. A cylindrical cutting wheel mounted on a position-controlled carriage has a circular groove is also programmed to bevel the edges of the lenses.
