Piercing Operation Sheet Metal

Both blanking and piercing are shearing operations.

Piercing operation sheet metal.

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. 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. 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 other words piercing operation produces an extruded hole 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. This allows for complex shapes to be formed in sheet metal up to 6 mm 0 25 in thick using simple tools.

The punch used in the piercing operation is usually bullet shaped. It consists of several different material parting operations such a piercing perforating shearing notching cutoff and blanking. Blanking piercing and punching comes under sheet metal cutting operations. 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.

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. 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. Difference between blanking and piercing.

It is one of the most extensively used processes throughout die and sheet metal work. Piercing is a shearing process where a punch and die are used to create a hole in sheet metal or a plate. Piercing operation produces an extruded hole or slot. Both punch and die are also applied in this operation.

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. Punching operation blanking operation piercing operation difference between punching and blanking shades of colour.
