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.

Computer numerical control system. A computer numerical control cnc system consists of three basic components. High repeatability and precision eg. Computer numerical control cnc machine. The system must automatically interpret at least some portion of this data. Computer numeric control a system in which actions are controlled by the direct insertion of numerical data at some point. In other words the numerical control machine is defined as the. Numerical control is defined as the form of programmable automation in which the process is controlled by the number letters and symbols. It is a principal element of computer integrated manufacturing particularly for controlling the operation of machine tools. 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 method of controlling machines by the application of digital electronic computers and circuitry. Numerical control popularly known as the nc is very commonly used in the machine tools. Advantages and disadvantages of cnc advantages. Numerical control also computer numerical control and commonly called cnc is the automated control of machining tools drills boring tools lathes and 3d printers by means of a computera cnc machine processes a piece of material metal plastic wood ceramic or composite to meet specifications by following a coded programmed instruction and without a manual operator. In case of the machine tools this programmable automation is used for the operation of the machines. Machine movements that are controlled by cams gears levers or screws in conventional machines are directed by computers and digital circuitry in computer numerical control cnc machines.

The general relationship of these three components is illustrated in figure 712. It is commonly used in manufacturing for machining metal and plastic parts. Part of smes fundamental manufacturing processes video series this program explains the basics of computer numerical control cnc by featuring segments on cnc principles and cnc programming. Cnc software which is a program of instructions a machine control unit and processing equipment also called the machine tool.
