  • Apparatus for generating ophthalmic products from blanks and a method of operating same
    Patent number: 5485771
    Abstract: An apparatus for use in the generation of ophthalmic products from blanks comprises a mechanism for rotating the blank about an axis of rotation. A cutter tool imparts a desired surface configuration onto the rotating blank. A first moving mechanism moves the cutter tool in a first direction oriented parallel to the axis of rotation of the blank. A second moving mechanism moves the cutter tool in a second direction oriented transverse to the first axis. A digital electronic system controls the angular displacement of the blank with respect to a reference plane containing the blank, and controls the movements of the cutter tool in the first and second directions. The movements of the cutter tool in the first and second directions, and the angular displacement of the blank about the axis of rotation are all controlled independently of one another by the digital electronic system.
