Computerized numerical control (CNC) systems govern automated machine tools capable of precisely shaping metal workpieces. These systems interpret coded instructions to direct the movement of cutting tools, enabling the creation of complex parts with high accuracy and repeatability. A common example is a milling machine automatically producing intricate components from a block of aluminum.
Automated machining offers significant advantages over traditional methods, including increased production speed, reduced material waste, and improved consistency. The ability to automate complex processes has revolutionized manufacturing, enabling the cost-effective production of intricate parts for industries ranging from aerospace to automotive. This technology has evolved significantly from its early implementations in the mid-20th century, driven by advancements in computing and electronics.
