Face milling is a machining process used to create flat surfaces on a workpiece. In this method, a rotating cutter with multiple teeth removes material from the surface of the metal or plastic part. The cutter moves across the surface, producing a smooth finish and precise dimensions. This technique is commonly used in manufacturing to prepare parts for assembly or to achieve specific tolerances. The face milling process can be performed on various machines, such as CNC mills or manual milling machines. It is essential for industries like automotive and aerospace, where high-quality surfaces are crucial for performance and safety.
