Blanking piercing and punching comes under sheet metal cutting operations.
Piercing operation in sheet metal.
Piercing operation produces an extruded hole or slot.
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.
There are two main operations of the sheet metal fabrication process.
It is one of the most extensively used processes throughout die and sheet metal work.
Both punch and die are also applied in this operation.
Both blanking and piercing are shearing operations.
Notching is a piercing operation that removes material from the edge of the workpiece.
In other words piercing is a combination of cutting and forming operation.
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.
As explained in the above image.
Sheet metal fabrication is a metalworking process to cut and form sheet metal into the desired shape which can be useful for end applications.
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.
The punch used in the piercing operation is usually bullet shaped.
Piercing in sheet metal.
Difference between blanking and piercing.
The nibbling process cuts a contour by producing a series of overlapping slits or notches.
This allows for complex shapes to be formed in sheet metal up to 6 mm 0 25 in thick using simple tools.
Piercing operation in sheet metal piercing operation produces an extruded hole or slot in sheetmetal.
One is cutting and the other is bending.
As a result of applied force from a piercing tool sheet metal starts tearing and produces an extruded hole or slot.
In other words piercing operation produces an extruded hole in sheet metal.
Piercing is the operation of punching holes in the sheet metal.
