Milling is a machining operation specifically designed for creating flat surfaces and other features on a workpiece. In milling, a rotating cutting tool moves across the workpiece, removing material to achieve the desired geometry. This process is highly versatile, allowing for the machining of not just flat surfaces but also intricate shapes, grooves, and contours, depending on the tool used and the configuration of the milling machine.

The use of a milling machine is ideally suited for producing flat surfaces due to its capability to control the depth of cut and the precise movement of the tool across the workpiece. Additionally, milling machines can operate on a variety of materials and can handle complex part configurations, which further emphasizes their effectiveness in shaping flat surfaces.

Turning, tapping, and forging serve different machining and manufacturing purposes. Turning is primarily concerned with producing cylindrical shapes, tapping is used for creating internal threads, and forging involves shaping metal through deforming it under compressive forces. These processes are not specifically aimed at achieving flat surfaces, which is why milling is the operation most closely associated with that task.
