Piercing Operation Sheet Metal

Piercing is the operation of punching holes in the sheet metal.

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. Notching is a piercing operation that removes material from the edge of the workpiece. It is one of the most extensively used processes throughout die and sheet metal work. It consists of several different material parting operations such a piercing perforating shearing notching cutoff and blanking.

As a result of applied force from the piercing tool sheet metal starts tearing and produces extruded hole slot. Difference between blanking and piercing. Piercing is a shearing process where a punch and die are used to create a hole in sheet metal or a plate. Blanking piercing and punching comes under sheet metal cutting operations.

The nibbling process cuts a contour by producing a series of overlapping slits or notches. Both punch and die are also applied in this operation. There are two main operations of the sheet metal fabrication process. To sum up punching blanking and piercing are sheet metal shearing operations to modify existing blank.

In blanking the piece is cut off from the sheet and it becomes a finished part. 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. 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 a process by which a hole is cut or torn in metal.

The punch used in the piercing operation is usually bullet shaped. Piercing operation produces an extruded hole or slot. This allows for complex shapes to be formed in sheet metal up to 6 mm 0 25 in thick using simple tools. One is cutting and the other is bending.

Punching operation blanking operation piercing operation difference between punching and blanking shades of colour. In other words piercing operation produces an extruded hole in sheet metal. 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.
