Fundamentals on the miniaturization of sheet metal working processes.

A it is a forming process by pushing a punch against a flat sheet and forcing it into a die to take the required shape. Ongoing miniaturization in various technical fields such as the electronics industry or micro systems technology requires precise forming processes for the production of small and thin components. Both the die and the punch have shape of the part to be manufactured. 2007 john wiley sons inc.
