Piercing Operation In Sheet Metal

The nibbling process cuts a contour by producing a series of overlapping slits or notches.

Piercing operation in sheet metal.

One is cutting and the other is bending. 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. There are two main operations of the sheet metal fabrication process. As a result of applied force from the piercing tool sheet metal starts tearing and produces extruded hole slot.

Piercing operation produces an extruded hole or slot. 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. Piercing is the operation of punching holes in the sheet metal. 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 punch used in the piercing operation is usually bullet shaped. In other words piercing operation produces an extruded hole in sheet metal. Piercing operation in sheet metal piercing operation produces an extruded hole or slot in sheetmetal. Notching is a piercing operation that removes material from the edge of the workpiece.

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. In other words piercing is a combination of cutting and forming operation. This allows for complex shapes to be formed in sheet metal up to 6 mm 0 25 in thick using simple tools. Piercing is a shearing process where a punch and die are used to create a hole in sheet metal or a plate.

Piercing in sheet metal. Blanking piercing and punching comes under sheet metal cutting operations. It consists of several different material parting operations such a piercing perforating shearing notching cutoff and blanking. Difference between blanking and piercing.

Both punch and die are also applied in this operation. As explained in the above image. Both blanking and piercing are shearing operations.
