Computer numerical control (CNC) machining involves using pre-programmed computer software to control machine tools. This automated process creates parts from various materials with high precision. An example would be automatically producing complex components for aerospace applications, requiring intricate designs and tight tolerances.
Mastering this technology offers significant advantages. It increases production efficiency, improves consistency and accuracy, and enables the creation of highly complex parts often impossible with manual machining. The development of CNC machining evolved from early numerical control systems in the 1940s and 50s, revolutionizing manufacturing processes across diverse industries. Its impact on precision engineering and mass production continues to be profound.
