Shearing
Shearing is a manufacturing process in which unwanted material is trimmed/sheared from sheet metal. A tool known as a bench shear is normally used to cut through the sheet with a good amount of precision. Clean cut pieces of high quantities can be produced with this process. The main advantage is that there is no burning of material and no general loss of material as well. So large batches of simple shaped pieces can be produced efficiently.
Mechanism of Shearing
- Deformation
- Penetration
- Fracture
Advantages of Shearing
- The process is incredibly fast and hence quite efficient for large volume production.
- Precise and clean cuts are obtained.
- There are no major size constraints in regard to the sheet metal diameter.
- No chip wastage observed.
- No need of heating the metal, since the process can be carried out in room temperature.
- Various metals such as Aluminium, stainless steel, copper can be.
