What is Shearing in Machine Design?

Shearing is a mechanical cutting process used to separate metal sheets into smaller pieces. It involves applying a shearing force to metal sheets placed between two sharp blades. The blades move past each other, causing the metal to fracture along the shearing line. People commonly use this process to cut straight lines manually or with the assistance of hydraulic or mechanical shearing machines.

What is the difference between cutting and shearing?

Shearing is the demonstration or activity of cutting with shears or a shearing machine, as the fleece from sheep or the rest from fabric while cutting is (countable|uncountable) the activity of the action word to cut.

What are the two most common shearing operations?

Shearing operations, such as punching and blanking, have widespread recognition. In punching, the operator turns the sheared slug into scrap or repurposes it, while in blanking, the operator considers the slug as the usable part and the remaining material as scrap. Shearing may likewise be done between a die & punch.


Shearing finds widespread applications in the metal industry. It cuts sheets of various metals, including steel, aluminium, brass, and copper. Industries such as automotive, construction, aerospace, and manufacturing heavily rely on shearing to create components like panels, brackets, plates, and profiles. It is particularly suitable for producing large volumes of parts with consistent dimensions and precise straight edges.
