ymbol, moreover along with numerical control technology unceasing development and application domain expansion, he to national economy and the people39。s HyperMach engine bed feed rate reaches 60m/most greatlymin, fast is 100m/min, the acceleration reaches 2g, the main axle rotational speed has reached 60 000r/min. Processes a thin wall airplane part, only uses 30min, but the same ponents need 3h in the mon high speed milling machine processing, needs 8h in the plain milling machine processing。 In order to enhance the actuation performance and the use connection convenient intellectualization, like feedforward control, electrical machinery parameter autoadapted operation, automatic diagnosis load automatic designation model, self regulating grade。s special application and the technical knack in the control system, the fast realization different variety, the different scale open style numerical control system, forms has the bright individuality famous brand goods. At present the open style numerical control system architecture standard, the correspondence standard, the disposition standard, the movement platform, the numerical control system function storehouse as well as the numerical control system function software development kit and so on is the current research core. takes the new technical standard, the standard establishment about numerical control system design development standard As mentioned above, the open style numerical control system has a better versatility, the flexibility, the patibility, the extension, countries and so on US, European Economic Community and Japan implements the strategy development plan in abundance, and carries on the open style architecture numerical control system specification (OMAC, OSACA, OSEC) the research and the formulation, the world 3 biggest economies have carried on the nearly same science plan and the standard formulation in the shortterm, has indicated a numerical control technology new transformation time oning. Our country also started in 2020 to conduct China39。s foundation condition limit, the numerical control technology development is slow. The second stage is in the country “65”, “75” the period as well as “85” the earlier period, namely the introduction technology, the digestion absorption, establishes the manufacture domestically system stage initially. In this stage, as a result of reform and open policy and the national value, as well as the research development environment and the international environment improvement, our country numerical control technology research, the development as well as has all made the considerable progress in the product manufacture domestically aspect. The third stage is in the country “85” later period and “95” period, namely the implementation industrial production research, enters the market petition stage. In this stage, our country domestic product numerical control equipment industrial production has made the substantive progress. In “95” the last stage, the domestically produced numerical control engine bed domestic market percentage of reaches 50%, matched the domestically produced numerical control system (popular sedan) also to achieve 10%. Looks over our country numerical control technology near 50 year development course, specially passes through 4 5 year plan attacks, the overall looked has obtained following result. laid the numerical control technological development foundation, has grasped the modern numerical control technology basically. Our country basically has grasped now from the numerical control system, the servo actuated, the numerical control main engine, the special plane and the necessary foundation technology, in which majority of technologies has had carries on the mercialized development the foundation, the partial technologies mercialized, the industrial production. formed the numerical control industry base initially. In the attack achievement and in the partial technical mercialization foundation, established such as the Central China numerical control, astronautics numerical control and so on had the volume production ability numerical control system plant. Lanzhou electrical machinery plant, Central China numerical control and so on one batch of servosystem and servo electrical machinery plant as well as Beijing first machine tool factory, Jinan first machine tool factory and so on certain numerical control main engine plant. These plants have basically formed our country39。s development speed is very quick, not only but crosswise pared to (with overseas contrast) the technical level has the disparity, also has the disparity in certain aspect development speed, namely some precise and advanced numerical control equipment technical level disparity has the expanded tendency. From international looked that, is approximately as follows to our country numerical control technical level and the industrial production level estimate. a. In the technical level, probably falls behind with the overseas advanced level for 10~15 years, in precise and advanced technical aspect then bigger. b. In the industrial production level, the market share is low, the variety coverage fraction is small, but also has not formed the scale production。 The domestically produced numerical control system not yet establishes own brand effect, the user confidence is insufficient. sustainable development ability, to the petition before the numerical control technology research development, project ability is weak。s stability。s numerical control equipment finally with difficulty to have raises one39。
