  • Patent number: 6439961
    Abstract: A machining cell and process for deburring root edges of a turbine blade. The machining cell defines a work area enclosing a robot to pick up and transport a blade package between working stations within the cell. A supply conveyor transports the part to an orienter station inside the cell where the part is checked for type and proper orientation prior to being picked up by the robot and moved to a deburring station. The robot manipulates the package into engagement with an active cutting tool to remove material from the root edges. The robot then transports the package to a brushing station located within the cell. The robot moves the package so that edges of the root are subjected to the abrasive action of a rotating brush wheel. The finished part is then transported by the robot to a discharge conveyor which feeds the finished part outside of the cell.
