Piercing Operation Sheet Metal

The nibbling process cuts a contour by producing a series of overlapping slits or notches.

Piercing operation sheet metal.

Piercing is a shearing process where a punch and die are used to create a hole in sheet metal or a plate. One is cutting and the other is bending. Notching is a piercing operation that removes material from the edge of the workpiece. In other words piercing operation produces an extruded hole in sheet metal.

Difference between blanking and piercing. To sum up punching blanking and piercing are sheet metal shearing operations to modify existing blank. There are two main operations of the sheet metal fabrication process. In blanking the piece is cut off from the sheet and it becomes a finished part.

Piercing operation produces an extruded hole or slot. As a result of applied force from the piercing tool sheet metal starts tearing and produces extruded hole slot. 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. Blanking piercing and punching comes under sheet metal cutting operations.

Sheet metal fabrication is a metalworking process to cut and form sheet metal into the desired shape which can be useful for end applications. Both punch and die are also applied in this operation. Piercing is the operation of punching holes in the sheet metal. If the small removed piece is the useful part and the rest is scrap the operation is called blanking.

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 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. Both blanking and piercing are shearing operations. It is one of the most extensively used processes throughout die and sheet metal work.

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 punch used in the piercing operation is usually bullet shaped. Punching operation blanking operation piercing operation difference between punching and blanking shades of colour.
