Blanking
Blanking is a steel manufacturing process that involves putting a coil of sheet metal into a press and die to form a flat, geometric shape (or "blank"). The blank is punched out of a metal sheet during this process. The procedure and tools used in blanking are similar to those used in piercing, except that the removed part is used as a fresh metal piece.

Piercing
Piercing can be used to create slots, holes, or other cutouts in part. Piercing is a shearing process that involves using a punch and die to make a hole in sheet metal or a plate. Piercing punches the required shapes out of the metal sheet, which can be performed simultaneously with blanking. In the piercing process, the unusable piece is removed from the metal and becomes scrap.

Punching
The punching process uses a press pushing a punch through a metal form to create a hole with a precise shape and placement. The punching tool frequently separates the extra material from the newly created form. Punching may or may not involve shear.
CNC punching is essential for producing sheet metal blanks. Punching is a speedier operation that lends itself to metal fabrications with numerous comparable features or a higher volume of parts per run.

Embossing
Metal embossing is a process for imparting a design on metal sheets. The opposing side can produce a raised effect by pushing the metal with an embossing tool or stylus. The positive impression has a smooth surface that can shine or take pigment by laying the metal sheet on a rubber or foam pad.
Embossing is highly similar to engraving. However, engraving cuts a small portion of the metal to create a logo or a sign on a metal part. Embossing utilizes a preconfigured punch to make an indentation in the form of the desired message or image.

Bending
Bending is a fundamental process of shaping metal into desired shapes such as L, U, or V-shaped profiles. Metal bending produces a plastic deformation with stresses beyond the yield point but below the tensile strength. Bending often happens around a single axis.
When designing bends for stamped metal parts, it's critical to consider enough material – make sure your part and its stock have enough material to complete the bend.

Coining
The workpiece is stamped while placed between a die and a punch or press during the coining process. This action forces the punch tip to penetrate the metal, resulting in precise and repeatable bends. The deep penetration also has no spring-back effects by relieving internal stresses in the metal workpiece.
Coining can subject a component to extreme stress and strain. This causes a plasticized material flow so that the workpiece has smoother surfaces and edges and is more closely matched to the design tolerances. Coining is frequently used to reduce metal thickness and shape the part. Using the coining process can produce coins (metal currency).

Flanging
Flanging is the process of introducing a flare or flange onto a metal workpiece using dies, presses, or specialist flanging machinery. Tension (stretch) flanges and compression (shrink) flanges are the two fundamental types of flanges. Tension flanges are prone to splitting. Compression flanges are prone to wrinkle.
Flanging is similar to bending in that it is done along a curved line. This complicates the job slightly, necessitating the procurement of specialized flanging equipment.
