What is the difference between swagging and setting down in swagging operation?

In the swagging operation, "swagging" refers to the process of deforming a metal tube or rod by compressing it, usually to create a specific shape or to reduce its diameter. On the other hand, "setting down" involves reducing the length of the material by pushing the material into a die, typically to form a more precise end or taper. While both processes involve shaping metal, swagging focuses on altering the diameter or profile, whereas setting down is more about controlling the length and end configuration.
