CNC Milling Guide: 3-, 4- & 5-Axis Machining for Complex Parts

Short answer: CNC milling spins a multi-flute cutter against a fixed or indexed workpiece to remove material and cut flat surfaces, slots, pockets and complex 3D contours that turning cannot. Three-axis covers most prismatic parts; four- and five-axis add rotation for undercuts and compound angles; turn-mill centres combine both in one setup. Computer control delivers repeatable, tight-tolerance components across prototypes and production.
