Metal forming is a general term for a large group, that includes a wide variety of
manufacturing processes. Metal forming processes are characteristic in that the metal
being processed is plastically deformed to shape it into a desired geometry.
In order to plastically deform a metal, a force must be applied that will exceed the yield
strength of the material. When low amounts of stress are applied to a metal it will
change its geometry slightly, in correspondence to the force that is exerted
