Piercing Operation 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.

Piercing operation sheet metal.

One is cutting and the other is bending. If the small removed piece is the useful part and the rest is scrap the operation is called blanking. As a result of applied force from the piercing tool sheet metal starts tearing and produces extruded hole slot. In blanking the piece is cut off from the sheet and it becomes a finished part.

Both punch and die are also applied in this operation. It is a process by which a hole is cut or torn in metal. To sum up punching blanking and piercing are sheet metal shearing operations to modify existing blank. 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 consists of several different material parting operations such a piercing perforating shearing notching cutoff and blanking. Piercing is the operation of punching holes in the sheet metal. 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.

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. Blanking piercing and punching comes under sheet metal cutting operations. There are two main operations of the sheet metal fabrication process.

Piercing is a shearing process where a punch and die are used to create a hole in sheet metal or a plate. Difference between blanking and piercing. Punching or blanking is a process in which the punch removes a portion of material from the larger piece or a strip of sheet metal. Piercing operation produces an extruded hole or slot.

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. 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.
