【正文】 t play a decisive role. At present, the numerical control technology is undergoing a fundamental transformation, from specialpurpose closedopenloop control mode to the generalpurpose realtime dynamic openloop control mode. In an integrated basis, numerical control system to realize ultrathin, ultrasmall。 (4) servo drive technology。 (2) information processing, processing and transmission technology。s most advanced manufacturing technology and equipment, the core technology. Widely adopted by nations in the world manufacturing numerical control technology to improve manufacturing capacity and level, to improve the dynamic changing market adaptability and petitiveness. In addition, all industrial countries in the world and CNC numerical control technology and equipment will also be listed as a national strategic goods, not only to take significant steps to develop its own CNC technology and its industry, but also in the sophisticated numerical key technologies and equipment to China imposition of closures and restrictions. In short, the vigorous development of numerical control technology as the core of advanced manufacturing technology has bee the world39。The equipment industry39。 參考文獻(xiàn) [1] 王立新. 淺談數(shù)控技術(shù)的發(fā)展趨勢[J]. 赤峰學(xué)院學(xué)報(bào)，2007.
