Piercing is a shearing process where a punch and die are used to create a hole in sheet metal or a plate.
Piercing process in sheet metal.
Piercing is a metal forging technique that is often performed as an auxiliary process in conjunction with other forging processes in the manufacture of it can be used to create a cavity or hole in the work piece.
There are two main operations of the sheet metal fabrication process.
Sheet metal fabrication is a metalworking process to cut and form sheet metal into the desired shape which can be useful for end applications.
The web is created after multiple components have been produced and is considered scrap material.
One is cutting and the other is bending.
Blanking and piercing are shearing processes in which a punch and die are used to produce parts from coil or sheet stock.
The terms piercing and punching can be used interchangeably.
Sheet metal operations.
The piercing machine forces a tool known as a blanking punch through the sheet metal.
Piercing is a shearing process in which raw metal is pierced with a machining tool resulting in the creation of a circular or other shaped hole.

Piercing is the operation of punching holes in the sheet metal.
In case of piercing or punching the material which is cut out from the sheet metal is scrap and the reining material is the actual part.
Piercing in sheet metal.
Cut sheet metal with a jeweler s saw in any shape you choose to create a pendant or keychain.
As explained in the above image.
Difference between blanking and piercing.
In other words piercing operation produces an extruded hole in sheet metal.
So having a basic idea about sheet metal fabrication process is important before we jump into blanking piercing and punching.
As a result of applied force from the piercing tool sheet metal starts tearing and produces extruded hole slot.
As the raw metal is pierced the metal from the newly created hole is considered scrap.
Blanking piercing and punching comes under sheet metal cutting operations.
Optionally polish your shape with a rotary tool.
The slugs produced by piercing internal features are also considered scrap.
Refine the shape with needle files then use various grits of sandpaper to create a smooth surface.
There are many specialized types of piercing.
Piercing operation produces an extruded hole or slot.
Blanking produces the outside features of the component while piercing produces internal holes or shapes.
The process and machinery are usually the same as that used in blanking except that the piece being punched out is scrap in the piercing process.
