Computerized numerical control (CNC) machining uses pre-programmed computer software to control the movement of machine tools. This automated process offers high precision and repeatability in shaping metal workpieces. A common example is the creation of complex parts for aerospace applications from a solid block of aluminum.
Automated machining has revolutionized manufacturing. Its accuracy minimizes material waste and reduces production time, leading to significant cost savings. The ability to create intricate designs with consistent quality has expanded design possibilities across various industries, from automotive and medical device manufacturing to consumer electronics. This automated approach has its roots in the mid-20th century with the development of numerical control, evolving into the sophisticated, computer-driven processes widely used today.
