【導(dǎo)讀】代發(fā)展的大趨勢(shì)。從目前世界上數(shù)控技術(shù)及其裝備發(fā)展的趨勢(shì)來看，其主要研究熱點(diǎn)有以下。幾個(gè)方面［1～4］。效率、質(zhì)量是先進(jìn)制造技術(shù)的主體。高速、高精加工技術(shù)可極大地提高效率，提高產(chǎn)品。的質(zhì)量和檔次，縮短生產(chǎn)周期和提高市場(chǎng)競(jìng)爭(zhēng)能力。為此日本先端技術(shù)研究會(huì)將其列為5大。材料為鋁或鋁合金，只有在高切削速度和切削力很小的情況下，才能對(duì)這些筋、壁進(jìn)行加工。眾多的鉚釘、螺釘和其他聯(lián)結(jié)方式拼裝，使構(gòu)件的強(qiáng)度、剛度和可靠性得到提高。速加工中心組成的生產(chǎn)線部分替代組合機(jī)床。德國(guó)DMG公司的雙主軸車床的主軸速度及加速度分別達(dá)12*!用領(lǐng)域進(jìn)一步擴(kuò)大。但過去因5軸聯(lián)動(dòng)數(shù)控系統(tǒng)、主機(jī)結(jié)構(gòu)復(fù)雜等原因，其價(jià)格要比3. 和成本大幅度降低，數(shù)控系統(tǒng)的價(jià)格差距縮小。定，預(yù)示了數(shù)控技術(shù)的一個(gè)新的變革時(shí)期的來臨。數(shù)控技術(shù)誕生后的50年間的信息交換都。顯然，他已越來越不能滿足現(xiàn)代數(shù)控技術(shù)高速發(fā)展的需要。為此，國(guó)際上正在研究和制定一

　　

【正文】 ion part specialization production level and plete set ability are low。 Outward appearance quality relative error。 The reliability is not high, the mercialized degree is insufficient。 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。 Numerical control technology application domain development dynamics is not strong。 Correlation standard standard research, formulation lag. our country numerical control technology and industrial production development strategic ponder strategy consideration Our country makes the great nation front end, but must accept in the world industry shift is not the rear end shift as far as possible, namely must grasp the advanced manufacture core technologies, otherwise in the new turn international industrial structure adjustment, our country manufacturing industry will go a step further “the spatial core”. We take the resources, the environment, the market as the price, the exchange obtain possibly merely are in the world new economical pattern international “the processing center” and “the assembly center”, but the nongrasping core technologies manufacturing center status, will like this be able to affect our country modern manufacturing industry seriously the development advancement. We should stand in the national security strategy take the numerical control technology and the industrial question highly, first looked from the security, social, because the manufacturing industry is our country employed population most professions, not only the manufacturing industry development may raise people39。s living standard, moreover also may alleviate our country employment the pressure, the safeguard society39。s stability。 Next looked safely from the national defense that, the Western developed country all lists as the precise and advanced numerical control product the national strategic material, realizes to our countr y embargoes and limits, “the Toshiba event” and “Cox reported” is the best illustration. development strategies Embarks from our country fundamental realities of the country angle, take the national strategic demand and the national economy market demand as the guidance, take enhances our country to make the equipment industry synthesis petitive ability and the industrial production level as the goal, with the system method, the choice can lead the 21st century initial period our country to make the key technologies as well as the support industrial production development support technology, the necessary technology which the equipment industry development promotes takes the research development the content, the realization manufacture equipment industry cross leap type development. Emphasized the market demand is the guidance, namely by the numerical control terminal product primarily, by the plete machine (for example quantity big surface broad numerical control lathe, milling machine, high speed high fine high performance numerical control engine bed, model digitization machinery, key profession essential equipment and so on) leads the numerical control industry the development. Key solution numerical control system and correlation function part (digitization servosystem and electrical machinery, high speed electricity main axle system and new equipment appendix and so on) reliable and scale of production question. Does not have the scale not to be able to have the redundant reliable product。 Does not have the scale not to be able to have the price inexpensive and the rich petitive power product。 Certainly, does not have the scale China39。s numerical control equipment finally with difficulty to have raises one39。s head the date. In the precise and advanced equipment research and development aspect, must emphasize produces, studies, grinds as well as enduser39。s close union, take “does obtains, usefully, sells falls” as the goal, implements the attack according to the national will, solves urgent need of the national. Before the petition the numerical control technology aspect, emphasizes the innovation, emphasized the research development has the proprietary intellectual property rights technology and the product, for our country numerical control industry, the equipment manufacturing industry and even the entire manufacturing industry sustainable development lays the foundation.
