摘要： A method for bending a tube in a pre-selected geometry includes deriving at least one processing parameter from the geometry, applying a thermal source circumferentially to the tube to heat the tube along at least one circumferentially directed path in accordance with the parameter and actively cooling the tube to a pre-selected temperature. The applying and active cooling steps are alternately performed a number of times. A system for bending the tube includes a thermal source for heating at least one region along the path on the tube, a tube advancing module for advancing the tube, an active cooling module for cooling the tube to a pre-selected temperature, a processing module to derive at least one processing parameter from the geometry and a control module configured to control the thermal source and active cooling module in accordance with the parameter. The alternate heating and cooling are performed a number of times.

摘要： A deposition friction stir weld process of joining work pieces includes placing a filler material on and about a joint line formed by butting a first work piece surface against a second work piece surface; and frictionally heating the filler material to soften the filler material and portions of the first and second work piece surfaces in thermal contact with the filler material and form a weld between the first and second work pieces, wherein frictionally heating is at a temperature below a melting point of the filler material and the first and second workpiece surfaces. Also disclosed herein are friction stir welding assemblies for providing the deposition friction stir weld as well as processes for depositing filler material and contouring a workpiece surface.

摘要： A die for reducing the formation of flash on parts includes a first die section and a second die section defining therein a cavity. The first die section includes a pair of first surfaces and the second die section includes a pair of second surfaces which together define a pair of parting lines which extend from opposite sides of the cavity. Desirably, the first die section includes a pair of lands, each extending along the length of one of the parting lines. Each land defines a first surface portion of the first surface and is sized and configured so that the land is elastically loaded, e.g., substantially equal to and less than the elastic limit of the material forming land when forming a part. In another embodiment, a die for reducing the formation of flash includes a land sized and configured so that when a first die section and a second die section are clamped together for forming the part, a second surface portion of the first surface of the first die section engages a second surface of the second die and the stress on the first surface portion is substantially equal to and less than an elastic limit of the land. In a third embodiment, a die includes a first die section and a second die section having a first surface and a second surface, respectively, which together define a parting line having at least one bend for controlling the formation of flash. Methods for forming such dies and methods for forming parts having reduced or controlled formation of flash are also disclosed.

摘要： A method for determining an equilibrium configuration for an object to be subjected to peening includes representing a bulk geometry of the object as a solid body and representing a surface of the object as a surface layer overlying the solid body. The method further includes expanding the surface layer in response to a number of thermal loads to simulate peening and balancing a number of forces on the surface layer and the solid body to determine the equilibrium configuration of the object after peening.
