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.

Abstract: A planetary-type deburring arrangement for removing burrs associated with inside and outside edges of a metal workpiece. The deburring arrangement includes a planetary head arrangement having a carier which rotates about a central axis. The carrier mounts thereon at least three rotatable spindles disposed in a generally circular pattern about the central axis, and each spindle mounts thereon an abrasive disc having an end face constructed of an abrasive media for deburring the workpiece. A first drive arrangement causes rotation of the carrier about the central axis. A second drive arrangement, including a planetary arrangement, is coupled to each of the spindles to effect rotation of each spindle individually about its own axis, with at least one of the spindles being rotated in an opposite direction from the other spindles.
