Several cutting processes are used to cut sheet metal. However, the shearing process by itself refers to a specific cutting process

that produces straight line cuts to separate a piece of sheet metal. In common, shearing is used for cutting a sheet parallel to an

existing edge which is held square, but angled cuts can be made as well. For this reason, shearing is mainly used to cut sheet 

stock into smaller sizes in preparation for other processes. 

The shearing process is performed on a shear machine, often called a squaring shear or power shear, that can be operated 

manually by hand or by hydraulic, pneumatic, or electric power. A typical shear machine includes a table with support arms to hold 

the sheet, stops or guides to secure the sheet, upper and lower straight-edge blades, and a gauging device to precisely position the

sheet. The sheet will be placed between the upper and lower blade, which are then forced together against the sheet, cutting the 

material. In most cases, the lower blade keep still while the upper blade is forced downward. The upper blade is slightly offset from 

the lower blade. Also,the upper blade is usually angled so that the cut progresses from one end to the other, thus reducing the 

required force. The blades used in these machines typically have a square edge rather than a knife-edge and are available in different

materials, such as low alloy steel and high-carbon steel.
