Milling machines are powerful tools used to remove material from a workpiece by feeding it into a rotating cutting tool. In most milling setups, the cutting tool spins in place while the workpiece is moved beneath or alongside it in a controlled manner. This relative motion between the spinning tool and the workpiece allows for precise cutting of flat surfaces, grooves, slots, and more complex shapes.
The movement of the workpiece is carefully guided by the machine, typically along straight paths in different directions. This control makes milling ideal for producing parts with accurate dimensions and smooth finishes. Whether using a manual machine or a computer-controlled system, understanding how the workpiece is guided into the tool—and how that affects the cutting action—is essential for successful machining.
