M p groover fundamentals of modern manufacturing 3 e basic types of sheet metal processes 1. 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. 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. Examples sheet metal formed.

Various stresses involved force required shearing operations punching blanking nibbling etc. 9 boothroyd dewhurst and knight. Or in other words drawing is the operation of producing thin walled hollow shaped parts from sheet metal. Kals fertigungstechnologie universitat erlanyen nurnberg erlangen germany received on january 9 1996 abstracf the miniaturization of components and therefore the downscaling of metal forming processes as it can be observed today especially in the field of electronics production is closely.

As a result so called second order size effects occur. Bending straining sheet around a straight axis 3. 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. For example thin metal foils are being used in microelectromechanical systems electronic components and medical devices.
