Computer numerical control and automation. 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 cnc is a method for automating control of machine tools through the use of software embedded in a microcomputer attached to the tool. Numerical control 1 2. Numerical control popularly known as the nc is very commonly used in the machine tools. As discussed above numerical control is a form of programmable automation in which a machine is controlled by numbers and other symbols that have been coded on punched paper tape or an alternative storage medium. Taylor tool metal hss automated production equipment screw machines transfer lines assembly lines using cams and preset stops programmable automation nc plc robots. Numerical control refers to a system that includes hardware and software. It is commonly used in manufacturing for machining metal and plastic parts. Numerical control is defined as the form of programmable automation in which the process is controlled by the number letters and symbols. 3 numerical control 1. Automation production systems and computer integrated manufacturing third edition by mikell p. 20th century fw. The utilization of cam enables the automation and computer support of all the production activities on the shop floor in order to manufacture parts designed with computer aided design cad and analysed with computer. Historical development 15th century machining metal. 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.

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.
