| Abstract Scope |
Submerged bobbin tool (SBT) tunneling is a new friction stir processing (FSP) technique for making integral channels within malleable materials. Like a conventional bobbin tool (BT) for friction stir welding (FSW), an SBT toolset has two opposing shoulders spaced apart along the bobbin or probe section of the tool. Unlike a conventional BT, an SBT is used to form integral sub-surface channels by passing the shoulder at the distal end of the probe through the workpiece during processing. Example uses of internal pathways are found in heat exchangers, cooling plates, and vacuum tools. Advance uses may include lessening weight and modifying the stiffness of structural components. A preliminary evaluation in AA6061-T6511 plates shows this special form of FSP has low process forces and is therefore capable of being deployed on CNC (computer numerical control) machining centers and friction stir-capable industrial robots as well as purpose-built FSP machines. Consequently, SBT tunneling holds potential use in a wide range of applications requiring curvilinear internal pathways for wiring, gases, and fluids, as well as internal spaces for the placement of powders and solid materials like composites. |
