Sheet metal fabrication<\/a> processes involve a variety of methods and tools to cut thin metal sheets (< 6 mm thick) in order to achieve smaller, desirable pieces. These pieces are then used in various products and are essential in a multitude of industries such as robotics, medicine, home appliances, consumer electronics, etc.<\/p>\n

Let’s explore this topic further.<\/p>\n

Metal Shearing Processes<\/h2>\n

Shearing processes are cold mechanical cutting processes where the sheet metal is positioned between two sharp blades using guides or stops. The lower blade (or die) is stationary while the upper blade (or punch) slices through the metal in a fast blow. Both the die and the punch are typically made from tool steel<\/a> or carbide. The shearing force applied during this process subjects the sheet metal under stress and once the material’s ultimate shear strength is overcome, the material is cut.<\/p>\n

There are different methods to mechanically cut sheet metal but the basic concept uses cutting blades between the material. The equipment for this process can be operated in multiple ways (manual, electric, pneumatic, and hydraulic).<\/p>\n

These processes generally are more economical when producing slightly larger production runs due to the longer set-up times and costs related to special tooling and dies. For one-off parts and small production runs, other cutting processes, such as laser cutting<\/a>, tend to be more cost-effective.<\/p>\n

Explore the three primary shearing processes (shearing, blanking, punching) utilised by the metalworking industry along with their subprocesses and unique characteristics.<\/p>\n
