Lathes and turning centers cut a rotating part with a stationary cutting tool. The tool moves parallel and perpendicular to the workpiece axis to provide the desired finished shape.
Machining centers are machine tools that are used to automatically repeat operations on a workpiece. They are usually numerically controlled. Operations include drilling, reaming, tapping, milling, and boring.
Milling machines move a clamped workpiece into a fixed, rotating cutter; or move the cutter itself into a stationary workpiece. There are two basic configurations: vertical and horizontal.
