Blanking is the operation of cutting flat shapes from sheet metal. The outer area of metal remaining after a blanking operation is generally discarded as waste. Size of blank or product is the size of the die & clearance is given on punch. It is a metal cutting operation. In blanking, metal obtained after cutting is not a scrap if it is usable.
Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter. In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its ...
Sheet metal embossing is a metalworking process for producing raised or sunken designs or relief in sheet metal. In contrast to coining (which uses unmatched dies), embossing uses matched male and female dies [ 1 ] to achieve the pattern, either by stamping , or by passing a sheet or strip of metal between patterned rollers . [ 2 ]
Stamping (also known as pressing) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press , blanking, embossing ...
For the forming of sheet metal, such as automobile body parts, two parts may be used: one, called the punch, performs the stretching, bending, and/or blanking operation, while another part that is called the die block securely clamps the workpiece and provides a similar stretching, bending, and/or blanking operation. The workpiece may pass ...
Ironing is a sheet metal forming process that uniformly thins the workpiece in a specific area. This is not to be mistaken with fabric Ironing . This process involves using force to evenly flatten a piece of sheet metal into a uniform shape. [ 1 ]

A forming press, commonly shortened to press, is a machine tool that changes the shape of a work-piece by the application of pressure. [1]
A joggle bend in sheet metal (at top of image) and a hand joggling tool Joggling , [ 5 ] also known as joggle bending , is an offset bending process in which two opposite bends with equal angles are formed in a single action creating a small s-shape bend profile and an offset between the unbent face and the result flange that is typically less ...
