Fundamentals on the miniaturization of sheet metal working processes.

Press work is highly economical method of manufacturing. 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. Introduction to sheet metal work. Such basic features can be summarized as.

As a result so called second order size effects occur. Sheet metal refers to metal that has a high surface area to volume ratio. 16 kalpakjian design for sheetmetal working ch. Sheet metal forming basics.

Sheet metal work stock used for sheet metal processes is usually formed by rolling and comes in coils. The sheet metal is placed over a die block at which point a punch presses down. Curling is a forming process that involves de burring sheet metal to produce smooth edges. Molten metal from the furnace is taken and poured into metallic moulds and allowed to cool or solidify.

Groover fundamentals of modern manufacturing 2 e strain rate sensitivity theoretically a metal in hot working behaves like a perfectly plastic material with strain hardening exponent n 0 the metal should continue to flow at the same flow stress once that stress is reached. Miniaturization of sheet metal working processes causes changes in the relative contribution of relevant process parameters. Basic geometry feature of the dieface although an actual dieface is a rather complicated system of surfaces some basic geometry features can be identified. As a result so called second order size effects occur.

Sheet metal forming involves a wide range of processes that manufacture parts for a vast amount of purposes both seen and unseen. Ingot is the starting raw metal for all metal working process. 2002 john wiley sons inc. Sheet metal forming 2 810 d.

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. Miniaturization of sheet metal working processes causes changes in the relative contribution of relevant process parameters. Cooper sheet metal forming ch. Another common sheet metal forming process is bending.

Companies typically perform bending on sheet metal using either a brake press or similar machine press. Most of the sheet metal work is done on presses where a die and punch or other formed tools are required. The cooled solid metal mass is then taken out of the mould. It is defined as the mechanical working of metal at a temperature between that of hot working and cold working.
