  • System and method for planning a tool path along a contoured surface
    Patent number: 6597967
    Abstract: A automated manufacturing system is provided for performing a manufacturing operation along a contoured surface of a workpiece. The automated manufacturing system includes a movable member; a tool disposed on the movable member for performing a manufacturing operation; a path planning subsystem which is operable to generate path data based on dimensional data for the workpiece, where the path data is indicative of a path for traversing the tool along the surface of the workpiece; and a controller adapted to receive the path data from the path planning subsystem and operable to move the moveable member in accordance with the path data, thereby performing the manufacturing operation along the surface of the workpiece.
