  • Cutting tool using interrupted cut fast tool servo
    Patent number: 7328638
    Abstract: A cutting tool assembly having a tool post capable of lateral movement along a work piece to be cut and an actuator with a tool tip. The actuator provides for control of the movement of the tool tip in an x-direction into and out of the work piece in order to make discontinuous microstructures in it. The machined work piece can be used to make microstructured articles such as films having non-adjacent lenslets.
    Type: Grant
