PUNCHING	BLANKING
Punching is a method of machining that includes removing scrap metal from a raw metal sheet.	Blanking is often mistaken with piercing as both procedures involve cutting raw metal holes.
Punching is a metal working process that involves creating holes in a metal workpiece.	Blanking is a metal fabrication process where the final product is removed out of the larger metal sheet, and the remaining material is discarded as scrap.
The material removed (punched out) is discarded, and the final product is the remaining material.	The final product is removed out of the larger metal sheet, and the remaining material is discarded as scrap.
The main thing to remember is that punching in sheet metal typically produce a single hole.	The main thing to remember is that blanking outcomes in a single piece of sheet metal creating various metal components.
Example: Punching a hole in a piece of paper (assuming the hole is the desired outcome).	Example: A cookie cutter used to cut out cookie from dough. Since the cookie is the desired product, it is blanking (cookie is the blank).
