Incremental Sheet Metal Forming with Sequential Two-Sided Tool Processing
This invention is a method and device for incrementally forming sheet metal by working it from both sides — top and bottom — in sequence using a forming tool. The sheet is clamped around its perimeter to hold it in place while the tool progressively shapes a structure into it. By alternating between the upper and lower surfaces, complex geometries can be achieved that would be difficult or impossible with single-sided incremental forming alone.
Piezoresistive Sensor Unit for Monitoring Mechanical Force in Connected Components
This invention is a thin-film sensor unit designed to be placed under a bolt or screw — essentially built into or around a standard washer — to continuously monitor whether the fastener remains properly tightened. The sensor layer is made from a carbon nanotube–polymer nanocomposite whose electrical resistance changes in direct proportion to the mechanical force pressing on it, allowing even tiny loosening events to be detected in real time. The sensor connects via a plug-in electronics module containing a signal processor, wireless or wired transmitter, and a small battery that can power the system for at least six months without external power. The entire assembly is designed to be a drop-in replacement for an ordinary washer, requiring no modification to existing bolted joints.
Incremental Sheet Metal Forming from Both Sides for Complex Shapes
This invention is a method and device for incrementally forming flat structures into metal sheets without causing unwanted warping or distortion. A sheet is clamped around its edges between two template plates, and a forming tool (such as a punch mandrel or roller) first presses a shallow structure into the top surface of the sheet. The sheet is then flipped — ideally while still clamped to prevent stress release — and the same or a second tool partially pushes the structure back from the underside. This two-sided sequential forming balances the internal stresses on both faces of the sheet, so that when the finished part is released from the clamp it remains flat rather than curving or buckling.
