Blanking piercing; punching or blanking is a process in which the punch removes a portion of material from the larger piece or a strip of sheet metal. If the small removed piece is the useful part and the rest is scrap, the operation is called blanking: it is a process by which a hole is cut (or torn) in metal.

Blanking is a shearing process where a punch and die are used to create a blank from sheet metal or a plate. The process and machinery are usually the same as that used in piercing, except that the piece being punched out in the piercing process is scrap.
After blanking operation, the parts will be require secondary finish to smooth out burrs with bottom edge. Shearing sheet metals the sheet metal blanking process is require such as blanking punch, blanking die, blanking press and sheet metal stock.
Blanking is a stage in the manufacturing process where dies are used to punch metal blanks in preparation for processing and finishing. For example, a company manufacturing medals can run a coil of sheet metal through a blanking machine, which cuts out circles which can be stamped with the medal design.

In blanking operations, the final part or product is removed or “punched-out” out of the larger sheet material, with the remaining material being discarded as scrap. On the other hand, in punching operations, the material removed is discarded, and the final product is the remaining material which then undergoes further processing.
