Computer numerical control history. Computer numerical control has a long history of change and development from the 1950s until today and the future looks bright for this profession. Computer numerical control has a long history of change and development from the 1950s until today and the future looks bright for this profession. Numerical control popularly known as the nc is very commonly used in the machine tools. Numerical control control of a system or device by direct input of data in the form of numbers letters symbols words or a combination of these forms. Numerical control is defined as the form of programmable automation in which the process is controlled by the number letters and symbols. Computer numerical control is a modern concept in the manufacturing and production industries. The first nc machines were built in the 1940s and 1950s based on existing tools that were modified with motors that moved the controls to follow points. In other words the numerical control machine is defined as the. It is a principal element of computer integrated manufacturing particularly for controlling the operation of machine tools. In case of the machine tools this programmable automation is used for the operation of the machines. Since the industrial revolution modern life has depended on advanced machinery to manufacture everything from textiles to steelthe advent of computer numerical control cnc machines revolutionized the manufacturing industry by allowing for a programmable design of virtually limitless types of shapes. The history of numerical control nc began when the automation of machine tools first incorporated concepts of abstractly programmable logic and it continues today with the ongoing evolution of computer numerical control cnc technology. The history starts with early efforts to automate industrial machinery such as looms. The idea of numerical control started when the automation of machine tools originally incorporated specific concepts of programmable logic. The history of computer numerical control cnc jan 26 2017.
