CNC turning represents a conventional subtractive manufacturing method employing cutting tools to eliminate material from the exterior of a workpiece. As the workpiece spins continuously, surplus fragments are gradually removed until it attains the desired shape, diameter, and final product size. CNC turning is adept at processing metals, wood, plastics, and various polymers. Furthermore, the utilization of computer-generated programs and codes in this procedure often results in products boasting superior dimensional accuracy.

CNC milling, alternatively manual milling, serves as a machining technique tailored for shaping prismatic components. A milling cutter, featuring a rotating cylindrical cutting head with multiple chip grooves, commonly known as an end mill, can traverse along distinct axes to tackle narrow and elongated spaces, grooves, outer profiles, and more. The machinery designated for milling is termed a milling machine, with CNC milling typically referring to a CNC machining center. Milling operations encompass both manual and CNC milling methodologies.
