METAL FORMING
Forces and deformations during the hot and cold metal forming depend upon mechanical properties of processed mate-rials, which in their turn depend upon the nature (chemical composition, structure) of metal as well as upon the defor- mation conditions (temperature, degree and rate of defor- ...

Metal forming processes
iitg.ac.inSheet forming: Sheet metal forming involves forming and cutting operations performed on metal sheets, strips, and coils. The surface area-to-volume ratio of the starting metal is relatively high. Tools include punch, die that are used to deform the sheets. Classification of basic sheet forming processes Bending Deep drawing shearing
