When it comes to forming rivets in an assembly, manufacturers are faced with many decisions as to which process would work best for their project. Often, these companies turn to traditional press forming without researching additional possibilities. While pressing has its place in manufacturing, there are many reasons why manufacturers are now turning to orbital forming to form their assembly.
First, due to the tooling path, orbital forming requires up to eighty percent less force than a traditional press. The tool, called a “peen”, advances at a 6-degree angle and rotates around the sides of the rivet to gently massage the material into place. This process induces the lowest force possible during the forming process. With less force needed, a smaller, more budget friendly machine with a minimal footprint can be used.
Orbital forming is a more consistent and controlled process. As the material is gently massaged into place, forming force and speed help to determine the functionality of the joint. This control allows for articulation within a joint, allowing for very specific torque requirements. Minimal shank swell within the joint provides protection for delicate parts or, by increasing the forming force, maximum retention in the joint can be accomplished. Also, due to the low force, there is a lower risk of material fracture during the forming process, and the finished form is more aesthetically pleasing.
Finally, with orbital forming, less CAPEX investments are required. Smaller forces allow for the use of a smaller machine with less initial cost and preventative maintenance. Additionally, with less force induced, the tooling lasts longer than that of a traditional press.
When choosing between a press or orbital forming machine, there are many things to take into consideration. From functional specifications to finished form aesthetics and CAPEX requirements, many manufacturers have moved to orbital forming to create the best possible assembly.
