What does "shearing" refer to in sheet metal fabrication?

Shearing in sheet metal fabrication specifically refers to the process of cutting along a straight line using a shear. This method utilizes a tool that applies a shearing action to separate the material without generating heat, providing a clean and precise cut. The process is commonly employed when fabricating parts, as it allows for efficient and accurate cutting of sheet metal into desired shapes or sizes.

Using shears, operators can cut through various thicknesses of metal sheets, ensuring that the edges remain straight and smooth, which is essential for subsequent handling and installation. This application is fundamental in the sheet metal industry, as it directly impacts the quality and dimensions of the final product. The other methods listed, such as torch cutting, bending, or joining metal, involve different processes and tools that serve distinct purposes, further emphasizing the uniqueness of shearing in fabrication.
