Abstract: A nut plate assembly includes a nut retainer and a bushing for expanding a tubular body of the retainer. The retainer assembly is used to cold work an opening of a workpiece in order to fix the nut retainer assembly relative to the workpiece. A nut can be snapped into the retainer. A method of installation includes passing a mandrel through the bushing to radially expand the bushing into a tubular body of the retainer. The tubular body is compressed between the workpiece and bushing as the bushing is displaced radially causing corresponding radial displacement of the tubular body. The expanded bushing applies pressure to the tubular body for a desired fit between the nut retainer and workpiece.

Abstract: A processing tool to process workpieces, for example cold working holes and/or installing expandable members into holes includes an expansion assembly with a plurality of elongated expansion segments. A first band and a second band couple the expansion segments into an array with the expansion segments circumferentially distributed about a longitudinal axis, with a passageway extending between the arrayed segments. The processing tool may include a tuning assembly that allows a radial expansion amount of the expansion assembly to be adjusted without altering a stroke length of a drive member of the processing tool. Sensors may sense various aspects of the processing performed by the processing tool to enable analysis and storage of information regarding performance of the process and/or materials processed by the processing tool.
