Fundamentals on the miniaturization of sheet metal working processes.

Miniaturization of sheet metal working processes causes changes in the relative contribution of relevant process parameters. With the use of the industrial manufacturing process sheet metal is formed by working metal into flat and thin pieces sheet metal is one of the very convenient ways that is used in metal working and it can be mended and cut into various shapes and dimensions. 2007 john wiley sons inc. The present paper should give a survey of different kinds of second order size effects that can be expected in tensile testing air bending and punching of sheet metal.

Groover fundamentals of modern manufacturing 2 e sheet metalworking forming and related operations performed on metal sheets strips and coils high surface area to volume ratio of starting metal which distinguishes these from bulk deformation often called pressworking because presses perform. This lecture describes the shearing operations in detail. 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. Or in other words drawing is the operation of producing thin walled hollow shaped parts from sheet metal.

For example thin metal foils are being used in microelectromechanical systems electronic components and medical devices. Fundamentals on the manufacturing of sheet metal microparts m. As a result so called second order size effects occur. Both the die and the punch have shape of the part to be manufactured.
