【正文】 ent and the work process control technologyCNC equipment is based on CNC technology as the representative of the new technology to traditional industry and burgeoning manufacturing industry form the infiltration of electromechanical integration products, the socalled digital equipment。 In which， Numerical control technology and equipment covering many fields：（ 1） Mechanical manufacturing technology。（ 2）Information processing, processing, transmission technology。 （ 3 ）Automatic control technology。(4) Servo drive technology。(5) Sensor technology。(6) Software technology, and so on. In the future economic and technological development trend of numerical control technology and equipment has its corresponding development trend. At the same time, in order to adapt to the trend of the world changes, China in these areas will have their own research and development strategy. (一 )The development trend of numerical control technology The application of numerical control technology not only to the traditional manufacturing industry has brought revolutionary changes, the manufacturing industry to bee a symbol of industrialization, But with the continuous development of NC technology and the expansion of application fields, But with the continuous development of NC technology and the expansion of application fields, he to the beneficial to the people39。s livelihood of some important industry development plays an increasingly important role, because these industries needed equipment digital is a modern development trend. ( IT, automobiles, light industry, medical and other )。 From the numerical control technology and equipment development trend, its main research focus has the following several aspects ( 1～ 4 ). speed, high precision processing technology and equipment of the new trends in efficiency, quality and advanced manufacturing technology is the subject. High speed, high precision machining technology can greatly improve efficiency, improve product quality and grades, to shorten the production cycle and improve market petition ability. Therefore the Japanese advanced technology research can be classified as 5 large modern manufacturing technologies. International Production Engineering Institute ( CIRP ) which is identified as one of the research directions in the center of twentyfirst Century. In the 37 aerospace industry, the processing of parts and ponents for the thin wall and a thin band, rigidity is poor, made of aluminum or aluminum alloy, only at high cutting speed and the cutting force is small, can these tendons, wall processing. Recently the large integral aluminum alloy blank tunneling approach to manufacturing wing, fuselage and other large parts to replace multiple parts through a large number of rivets, screws and other connection way of assembling, make ponent strength, stiffness and reliability were improved. All of the processing equipment for highspeed, high precision and high flexibility requirements. From EMO2020 show situation, high speed machining center feed rate up to 80m/min, or even higher, empty running speeds of up to about 100m/min. Many of the world39。s current automobile factory in China, including the Shanghai General Motors Co, has been used in high speed machining center production line consisting of partial substitution of modular machine United States of America CINCINNATI pany HyperMach machine tool feed speed of the big 60m/min, fast 100m/min, acceleration of up to 2G, spindle speed has reached 60000r/min. Processing of a thinwalled aircraft parts, only 30min, while the same parts in the general high speed milling machine processing needs 3h, in the ordinary milling machine processing 8h。 DMG Germany39。s double spindle lathe spindle speed and acceleration are respectively 120200r/mm and 1G. In the machining accuracy, 10 years, nearly the general level the machining accuracy of NC machine tool has been improved from 10m to 5m, precision machining center from 3～ 5m, increased to 1 ～, and ultra precision machining accuracy has begun to enter the nanoscale ( ).In order to realize the high speed, high precision machining, with matching function parts such as electric spindle, linear motor has been rapid development, application domain expands further. axis machining and rapid development of posite processing machine with 5 axis linkage on 3D surface machining, cutting tool geometry can be best cutting, not only high smoothness, but also greatly improve the efficiency of. Generally, 1 sets of 5 axis machine tool efficiency can be equal to 2 sets of 3 axis machine tools, particularly the use of cubic boron nitride superhard materials such as milling cutter for high speed milling of hardened steel parts, 5 axis machining can be more than 3 axis machining more benefits. But in the past for 5 axis NC system, the host of plex structure and other reasons, its price than 3 axis linkage CNC machine several times higher, and the programming technology difficulty is greater, restricted the development of 5 axis machine tool. Because of the electric spindle, make the implementation of 5 axis machining posite spindle structure is simplified, the manufacturing difficulty and cost are greatly reduced, CNC system to narrow the price gap. It has promoted the pound head type 5 axis machine tool and pound processing machine tool (including 5 machine tools ) the 38 development. In the EMO2020 exhibition, SNK 5 processing machine using the pound head, can achieve 4 perpendicular to the plane of any point of processing and processing, so that the 5 surface processing and 5 axis machining can be realized in the same machine, but also can realize the inclined plane and the back taper hole processing. The German pany DMG exhibited DMUVoution series machining center, be in one clamping surface processing and
