CNC milling, or computer numerical control milling, is a machining process of rotating a cutting tool in a spindled axis to produce a shape or form. The cutting tool is controlled by a specialized computer, which greatly increases reliability and repeatability, while reducing the potential human error.
This process is suitable for machining a wide range of materials, such as metal, plastic, and wood, and producing a variety of custom-designed parts and products.Also it is good for producing high accuracy, high tolerance parts in prototype, one-off, and small to medium production runs.
