Milling machining is a method of machining with a cutting tool called a milling machine mounted on a rotating shaft. Because it allows the tool to intermittently contact and cut the fixed workpiece, it can not only machine the surface of the workpiece into a flat or curved surface but also perform various operations such as drilling and grooving.

Although milling machines have features like machine guards, emergency stops, and enclosures, much of the responsibility for safe operation falls on the machine operators. By paying careful attention to basic safety and maintenance, machinists play a critical part in the safety of manual and CNC machine mills.
