The material that is removed is the new metal workpiece or blank.
Sheet metal fine blanking.
It is also similar to stamping but differs in the sense that it uses two opposing dies to form the gear from sheet material.
Characteristics of the blanking process include.
The working principle fine blanking of a typical spur gear is presented in fig.
Blanking is a cutting process in which a piece of sheet metal is removed from a larger piece of stock by applying a great enough shearing force in this process the piece removed called the blank is not scrap but rather the desired part blanking can be used to cutout parts in almost any 2d shape but is most commonly used to cut workpieces with simple geometries that will be further shaped.
Place the metal sheet to be punched between the punching machine and the die.
The web is created after multiple components have been produced and is considered scrap material.
Figure 1 when a punch makes contact with the sheet the metal begins to deform and bulge around the point of the punch.
Detailed process introduction of punching and blanking.

Hope the following picture of a stamping factory experience will help you understand what is fine blanking and what difference between fine blanking and common punching and blanking process for sheet metal parts.
Blanking and piercing are shearing processes in which a punch and die are used to produce parts from coil or sheet stock.
As explained in the above image the blanking operation produces an enclosed part from a large piece of sheet metal.

After blanking operation the parts will be require secondary finish to smooth out burrs with bottom edge the fine blanking process is most method of blanking.
Shearing sheet metals the sheet metal blanking process is require such as blanking punch blanking die blanking press and sheet metal stock.
The tooling of fine blanking clearance will affect the final stamped part burrs height.
Fineblanking is a specialty type of metal stamping that can achieve part characteristics such as flatness and a full sheared edge to a degree that is nearly impossible using a conventional.
Blanking is a metal fabricating process during which a metal workpiece is removed from the primary metal strip or sheet when it is punched.
Fine blanking is a fully automated precision metal working stamping process.
Blanking produces the outside features of the component while piercing produces internal holes or shapes.
As a result the blank part is used as the final product.
Fine blanking is similar to extrusion where the metal is extruded through die cavities to form the desired gear tooth geometry.
