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.

Piercing operation in sheet metal.

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. 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.

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. 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. The punch used in the piercing operation is usually bullet shaped.

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

There are two main operations of the sheet metal fabrication process. Piercing operation in sheet metal piercing operation produces an extruded hole or slot in sheetmetal. Piercing is the operation of punching holes in the sheet metal. Both blanking and piercing are shearing operations.

In other words piercing operation produces an extruded hole in sheet metal. The nibbling process cuts a contour by producing a series of overlapping slits or notches. It consists of several different material parting operations such a piercing perforating shearing notching cutoff and blanking. Sheet metal fabrication is a metalworking process to cut and form sheet metal into the desired shape which can be useful for end applications.

Blanking piercing and punching comes under sheet metal cutting operations. One is cutting and the other is bending. Notching is a piercing operation that removes material from the edge of the workpiece.
