CNC, or Computer Numerical Control, refers to a sophisticated technology used in manufacturing and machining processes. It involves the automation of machinery and tools through computer programs and precise instructions. A CNC system utilizes a computer to interpret design files and convert them into precise movements and commands for the machinery. This automation allows for highly accurate and repeatable operations, making it a crucial tool in industries such as aerospace, automotive, and precision engineering, where intricate and consistent machining or cutting is essential. CNC machines are versatile and can be found in various forms, including milling machines, lathes, routers, and 3D printers, enabling the production of complex and customized parts with efficiency and precision.
