Shear forming is a metal forming process in which sheet metal is plastically deformed between two opposing tools with a sliding motion. The process is used to create components with specific shapes and dimensions. The tools used in shear forming typically include a top tool, a bottom tool, and a lubricant. The top tool applies pressure to the workpiece, while the bottom tool holds the metal in place and guides the shear forming process. The lubricant is used to reduce friction between the tools and the workpiece, which helps to reduce the amount of force required to deform the material. The process can be used to create components with complex shapes, including curved surfaces and angles.
