👉 A workpiece is a part of an assembly or product that requires precise and consistent dimensions, which are typically specified in terms of length, width, and height. Workpieces can be made from various materials such as metal, plastic, wood, or even fabric. The size and shape of the workpiece will determine how it will be assembled into a finished product. A common type of workpiece is a component that is used to assemble other components in an assembly line, such as screws or nuts.
