Piercing Operation In Sheet Metal

There are two main operations of the sheet metal fabrication process.

Piercing operation in sheet metal.

Piercing is the process in which desired shape holes are produced in a piece of sheet metal without eliminating any material from the sheet or removing a very small amount of material as shown in the figure. Sheet metal fabrication is a metalworking process to cut and form sheet metal into the desired shape which can be useful for end applications. Both blanking and piercing are shearing operations. Piercing operation in sheet metal piercing operation produces an extruded hole or slot in sheetmetal.

As explained in the above image. This allows for complex shapes to be formed in sheet metal up to 6 mm 0 25 in thick using simple tools. Blanking piercing and punching comes under sheet metal cutting operations. In other words piercing operation produces an extruded hole in sheet metal.

Piercing is the operation of punching holes in the sheet metal. Metal cutting is a process used for separating a piece of material of predetermined shape and size from the remaining portion of a strip or sheet of metal. Notching is a piercing operation that removes material from the edge of the workpiece. The punch used in the piercing operation is usually bullet shaped.

It consists of several different material parting operations such a piercing perforating shearing notching cutoff and blanking. The nibbling process cuts a contour by producing a series of overlapping slits or notches. As a result of applied force from the piercing tool sheet metal starts tearing and produces extruded hole slot. Piercing is a shearing process where a punch and die are used to create a hole in sheet metal or a plate.

One is cutting and the other is bending. 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. In other words piercing is a combination of cutting and forming operation. As a result of applied force from a piercing tool sheet metal starts tearing and produces an extruded hole or slot.

Both punch and die are also applied in this operation. It is one of the most extensively used processes throughout die and sheet metal work. Piercing operation produces an extruded hole or slot.
