Piercing Operation In Sheet Metal

A key part of this process is that there is not reduction of material only a modification in its geometry.

Piercing operation in sheet metal.

If the small removed piece is the useful part and the rest is scrap the operation is called blanking. 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. It is a process by which a hole is cut or torn in metal. In blanking the piece is cut off from the sheet and it becomes a finished part.

Lancing is a partial cutting operation where bending and piercing is done using the same punch. This is a form of. Piercing is a shearing process where a punch and die are used to create a hole in sheet metal or a plate. It consists of several different material parting operations such a piercing perforating shearing notching cutoff and blanking.

Shaving is a finishing operation where a small amount of material is removed from a previously pierced hole. It is one of the most extensively used processes throughout die and sheet metal work. Lancing is a piercing operation in which the workpiece is sheared and bent with one strike of the die. Plastic deformation fracture shear.

Piercing operation produces an extruded hole or slot. In other words piercing operation produces an extruded hole in sheet metal. Piercing lancing perforating notching nibbling trimming shaving. Other piercing techniques lancing.

As a result of applied force from the piercing tool sheet metal starts tearing and produces extruded hole slot. In case of a.
