Abstracts: By riveting we mean the upsetting of a rivet to form a head to hold several assembled parts together. The rivet can be in the form of a pin or an eyelet. An unconventional fastening technique cuts the cost of many material forming and assembly applications. Orbital forming, as the name implies, is a cold-forming process that uses an "orbiting" tool. Sometimes called spinning, radial riveting, or spin riveting, orbital forming is most often used to head, swage, crown, flare, or form a column or projection of material in fastening and assembly operations. The process is somewhat similar to impact and compression forming, where the tool applies a compressive axial load to plastically deform the part. The difference is that in orbital forming, the tool rotates at a fixed angle and applies both axial and radial forces to progressively move malleable material into a desired, predetermined shape. The aim this project is to making a ORBIT RIVETING MACHINE(ORM),that is unique process characterized by a variety of rivet head shapes and by very low force requirements.
