Cogging is the process of shaping a metal object by hammering it on a cog-shaped anvil. However, there are many other synonyms you can use to describe this process. One alternative phrase is "forging," which refers to shaping metal through heating it in a forge and then pounding it into shape. Another term is "swaging," which involves shaping a metal piece by using a die to force it into the desired form. "Bending" is also a similar term that entails reshaping a metal object by applying pressure until it conforms to a specific curve or angle. Finally, "forming" can be used to describe the process of altering the shape of a material, including metal, through pressure or heat.
