Shearing
Shearing is defined as separating material into two parts.
It utilizes shearing force to cut sheet metal.
Blanking :-
A piece of sheet metal is removed from a larger piece of stock.
This removed piece is not scrap, it is the useful part.
Fine Blanking :-
A second force is applied underneath the sheet, directly opposite the punch, by a "cushion".
This technique produces a part with better flatness and smoother edges.
