casting processes.

Sheet metal working
 Press working of sheet metals

 A chip less manufacturing process

 Also termed as cold stamping

 Wall thickness – constant/slightly differs from
initial material
 Initial
material: LCS, ductile alloy steels,
copper and its alloy, Al and its alloy

, Sheet metal working
 Advantages:

 Light weight of fabricated parts
 High productivity
 High efficiency of technique – simple and
complex shapes
 In many cases, no subsequent machining

, Sheet metal working
Sheet metal operations are done on a PRESS
 Main features of a
PRESS:
 Frame

 Source of

mechanism for
operating the ram
 Punch and die block

 Stamping

 Room temperature
