Piercing Operation In Sheet Metal

It consists of several different material parting operations such a piercing perforating shearing notching cutoff and blanking.

Piercing operation in sheet metal. Both blanking and piercing are shearing operations. As explained in the above image. 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. 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. In other words piercing operation produces an extruded hole in sheet metal. Blanking piercing and punching comes under sheet metal cutting operations. Both punch and die are also applied in this operation.

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 produces an extruded hole or slot. Piercing operation in sheet metal piercing operation produces an extruded hole or slot in sheetmetal. One is cutting and the other is bending.

The punch used in the piercing operation is usually bullet shaped. Difference between blanking and piercing. Piercing is the operation of punching holes in the sheet metal. Notching is a piercing operation that removes material from the edge of the workpiece.

There are two main operations of the sheet metal fabrication process. This allows for complex shapes to be formed in sheet metal up to 6 mm 0 25 in thick using simple tools. 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. As a result of applied force from the piercing tool sheet metal starts tearing and produces extruded hole slot.

In other words piercing is a combination of cutting and forming operation. The nibbling process cuts a contour by producing a series of overlapping slits or notches. Piercing is a shearing process where a punch and die are used to create a hole in sheet metal or a plate.
