外文翻译The numerical control technologyNumerical control technology is refers with digital, the writing and the mark composition digital command realizes one or the multi-Taiwan mechanical device movement control technology.It controls usually is the position, the angle, the speed and so on the mechanical quantity and flows to the related switch quantity with the mechanical energy.The numerical control production relies on data carrier and the binary mode data operation appearance.In 1908, perforation sheet metal exchange type data carrier being published; 19 century's ends, and have the assistance function control system take the paper as the data carrier to invent; In 1938, Shannon has carried on the data fast operation and the transmission in the American Massachusetts Institute of Technology, has established the modern computer, including computer numerical control system foundation.The numerical control technology is develops with the engine bed control close union.In 1952, first numerical control engine bed being published, became in the world mechanical industry history an epoch-making event, impelled the automated development. Because uses the computer substitution originally to use the numerical control installment which the hardware logic circuit composes, causes the data-in the storage, processing, the operation, the logical judgment and so on each kind of control function realization, may complete through the computer software. The numerical control engine bed is one kind of technical denseness and the automaticity very high integration of machinery processing equipment, is synthesizes the application computer, the automatic control, the automatic detection and precise…The processing precision is high, the qu...
