A numerical control machine inputs programs via punch cards. The programming is saved in a computer’s memory. CNC systems offer great computational capacity, providing manufacturers a diverse way to produce high-quality products and meet market expectations. Automated machines are operated via numerical control where software are designed to control or perform various action. The language behind a system is usually referred to as G-code, and it is developed to control, run, or monitor various behaviors of a machine. For example, a computer can help control the speed, feed rate, and coordination of a machine.
