 Spinning, radial riveting, spin riveting and peening are terms often used to refer to orbitforming, a cold-forming aluminumstandardextrusion process that uses an orbiting tool to aluminumstandardextrusion swage, head, crown, flare, or form a column or projection of malleable material for the purpose of fastening in assembly operations. The process is similar to impact and compression forming, where the tool applies a compressive axial load to permanently deform the part, according a designer, manufacturer, and integrator of forming, fastening and assembly systems The difference is that in orbital, the tool rotates at a fixed angle-typically aluminumstandardextrusion 3 aluminumstandardextrusion to 6 degrees-and applies both axial and radial forces to progressively move malleable material into a desired, predetermined shape. Unlike impact or compression forming, where the process is completed in a single pass, forming requires several tool revolutions and typically takes 1.5 to 3 seconds to complete. Additionally, most of the work during aluminumstandardextrusion orbital is at the tool''s line of contact, not along the entire tool surface. The resulting small-contact area reduces axial loads by as much as 80 percent. After the head is formed, the end of the fastener shank opposite the fastener head is spun in a chamfer tool. This aluminumstandardextrusion removes a small amount of metal from the end of the fastener shank creating a 30-45 degree chamfer angle on the end of the fastener shank. This chamfer acts as a thread relief when aluminumstandardextrusion mating with internally threaded products. The fastener is then moved to a thread roller where aluminumstandardextrusion the threads are formed into the fastener shank, ending the cold forming process. Strength and cost are two main considerations when choosing between cold forming and machining. When a part is cold formed the grain flow lines are neither cut nor broken aluminumstandardextrusion but follow the contour of the upset. This process increases the tensile strength of the part. Cold formed parts as compared to machined parts are stronger and tougher both statically and in fatigue, aluminumstandardextrusion therefore producing a higher quality end product.
