Facing (machining)

Facing in machining can be used in two different areas: facing on a milling machine and facing on a lathe. Facing on the milling machine involves various milling operations, but primarily face milling. On the lathe, facing is commonly used in turning and boring operations. Other operations remove material in ways similar to facing, for example, planing, shaping, and grinding, but these processes are not labeled by the term "facing."
