CNC machining is a manufacturing process in which computerized numerical control (CNC) machines are used to cut, shape, and drill materials. CNC machining is an exact and automated manufacturing method often used to produce complex and intricate parts. In CNC machining, a computer program is used to control the movements of the machine, allowing for very high levels of precision and repeatability. This makes CNC machining ideal for producing parts with tight tolerances and complex shapes. CNC machining is used in various aerospace, automotive, and medical industries.
