Piercing Operation In Sheet Metal

In other words piercing is a combination of cutting and forming operation.

Piercing operation in 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. It consists of several different material parting operations such a piercing perforating shearing notching cutoff and blanking. Piercing operation produces an extruded hole or slot. Piercing operation in sheet metal piercing operation produces an extruded hole or slot in sheetmetal.

Difference between blanking and piercing. As a result of applied force from a piercing tool sheet metal starts tearing and produces an extruded hole or slot. The nibbling process cuts a contour by producing a series of overlapping slits or notches. The punch used in the piercing operation is usually bullet shaped.

Piercing is a shearing process where a punch and die are used to create a hole in sheet metal or a plate. There are two main operations of the sheet metal fabrication process. Both punch and die are also applied in this operation. Piercing in sheet metal.

Blanking piercing and punching comes under sheet metal cutting operations. As explained in the above image. 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. It is one of the most extensively used processes throughout die and sheet metal work.

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. This allows for complex shapes to be formed in sheet metal up to 6 mm 0 25 in thick using simple tools. 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.

One is cutting and the other is bending. In other words piercing operation produces an extruded hole in sheet metal. Notching is a piercing operation that removes material from the edge of the workpiece.
