Description:
An MPEG-1 movie of robotic turbine blade grinding. The robot can remove varying amounts of excess material from the airfoil surface of a turbine blade to the desired shape and finish. Efficient process capabilities are achieved by the robot's compliant behavior and its ability to gather geometric data by contacting the workpiece and interrogating the CAD model. These capabilities are used to locate a crudely fixtured part, teach the robot the locations where grinding is required, accurately measure the surface flaws, and gauge progress while grinding. Arm compliances, tool paths and success metrics are automatically generated from the model and measurments. The resulting system can remove varying amounts of excess material and produce smooth, blended finishes. It supports small-lot production by permitting simple, low-cost part fixtures and rapid part programming.
