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. The cooled solid metal mass is then taken out of the mould. Sheet metal forming 2 810 d. 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.

Such basic features can be summarized as. Miniaturization of sheet metal working processes causes changes in the relative contribution of relevant process parameters. The sheet metal is placed over a die block at which point a punch presses down. Ingot is the starting raw metal for all metal working process.

Sheet metal forming involves a wide range of processes that manufacture parts for a vast amount of purposes both seen and unseen. In press work large force is applied on thin sheet metals to give the required shape or to cut it in to the desired shape. As a result so called second order size effects occur. Molten metal from the furnace is taken and poured into metallic moulds and allowed to cool or solidify.

It is defined as the mechanical working of metal at a temperature between that of hot working and cold working. Sheet metal refers to metal that has a high surface area to volume ratio. 16 kalpakjian design for sheetmetal working ch. Introduction to sheet metal work.
