Computer Numerical Control
Computer numerical control is a modern concept in the manufacturing and production industries.
History of computer numerical control. The history starts with early efforts to automate industrial machinery such as looms. 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. 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. Computer numerical control has a long history of change and development from the 1950s until today and the future looks bright for this profession. 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. 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. However the concept of cnc harkens back to the basic idea of nc or numerical control. 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.
