【正文】 開發(fā)研究。 C、數(shù)控裝備的網(wǎng)絡(luò)化將極大地滿足生產(chǎn)線制造系統(tǒng)、制造企業(yè)對信息集成的需求，也是實現(xiàn)新的制造模式的基礎(chǔ)單元。 五面加工中心，這種加工中心具有立式和臥式加工中心的功能，在工件一次裝夾后，能完成除安裝面外的所有五個面的加工，這種加工方式可以使工件的形狀誤差降到最低，省去二次裝夾工作，從而提高生產(chǎn)效率，降低加工成本。目前，數(shù)控系統(tǒng)采用位數(shù)、頻率更高的處理器，以提高系統(tǒng)的基本運算速度。為了 適應(yīng)柔性制造系統(tǒng)和計算機集成系統(tǒng)的要求，數(shù)控系統(tǒng)具有遠距離串行接口，甚至可以聯(lián)網(wǎng)，實現(xiàn)數(shù)控機床之間的數(shù)據(jù)通信，也可以直接對多臺數(shù)控機床進行控制。隨著 CIMS 技術(shù)的發(fā)展，當前又出現(xiàn)了 CAD／ CAPP／ CAM 集成的全自動編程方式，它與 CAD／CAM 系統(tǒng)編程的最大區(qū)別是其編程所需的加工工藝參數(shù)不必由人工參與，直接從系統(tǒng)內(nèi)的 CAPP 數(shù)據(jù)庫獲得。而利用新型的彩色液晶薄型顯示器替代傳統(tǒng)的陰極射線管，將使數(shù)控操作系統(tǒng)進一步 小型化。還通過自動運行啟動診斷、在線診斷、離線診 斷等多種診斷程序，實現(xiàn)對系統(tǒng)內(nèi)硬件、軟件和各種外部設(shè)備進行故障診斷和報警。還可以自動使故障模塊脫機，而接通備用模塊，以確保無人化工作環(huán)境的要求。 為適應(yīng)超高速加工的要求，數(shù)控機床采用主軸電動機與機床主軸合二為一的結(jié)構(gòu)形式，實現(xiàn)了變頻電動機與 機床主軸一體化，主軸電機的軸承采用磁浮軸承、液體動靜壓軸承或陶瓷滾動軸承等形式。 （ 3）按特殊功能分類有： 單工作臺、雙工作臺加工中心； 單軸、雙軸、三軸及可換主軸箱的加工中心； 立式轉(zhuǎn)塔加工中心和臥式轉(zhuǎn)塔加工中心； 刀庫加主軸換刀加工中心； 刀庫接寫手加 主軸換刀加工中心； 刀庫加機械手加雙主軸轉(zhuǎn)塔加工中心。它與力式加工中心相比，結(jié)構(gòu)復(fù)雜，占地面積大，質(zhì)量大，價格高。 （ 3）、提高機床加工生產(chǎn)率的研究 世界 NC 機床、加工中心及相應(yīng)的高速點主軸、直線電機、測量系統(tǒng)、 NC系統(tǒng)的開發(fā)，均以提高生產(chǎn)率為前提。t by artificial to participate in most, get from CAPP database in system directly. （ 5） . The dependability of the dependability maximization numerical control lathe has been the major indicator that users cared about most all the time . The numerical control system will adopt the circuit chip of higher integrated level , will utilize the extensive or super largescale specialpurpose and posite integrated circuit, in order to reduce the quantity of the ponents and parts , to improve dependability . Through the function software of the hardware, in order to meet various kinds of demands for controlling the function, adopt the module , standardization , universalization and seriation of the structure lathe noumenonn of the hardware at the same time , make not only improve the production lot of the hardware but also easy to is it produce to organize and quality check on.. Still through operating and starting many kinds of diagnostic programs of diagnosing , diagnosing , diagnosing offline online etc. automatically, realize that diagnoses and reports to the police the trouble to hardware , software and various kinds of outside equipment in the system. Utilize the warning suggestion, fix a breakdown in time。s knowledge plays is more outstanding , and the machine tool industry is regarded as the foundation of the manufacturing industry of the machine, its key position and strategic meaning are more obvious. Within 19911994 years, the economic recession of the world, expensive FMS, CIMS lowers the temperature, among 19952020 years, the international economy increases at a low speed, according to requisition for NC lathe and the world four major international lathes exhibition in order to boost productivity of users of various fields of present world market (EMO , IMTS , JIMTOF , China CIMT of Japan of . of Europe), have the analysis of the exhibit, there are the following several points mainly in the technical research of NC lathe in our times: （ 1）、 Pay more attention to new technology and innovation Worldwide , are launching the new craft , new material , new structure , new unit , research and development of the new ponent in a more costeffective manner, developmental research of for instance new cutter material , the new electric main shaft of main shaft structure , high speed , highspeed straight line electrical machinery ,etc.. Regard innovating in improvement of the processing technology as the foundation, for process ultra and hard difficult to cut material and special posite and plicated part , irregular curved surface ,etc. research and develop new lathe variety constantly. （ 2）、 Improve the precision and research of machine tooling In order to improve the machining accuracy of the machining center , are improving rigidity of the lathe , reduction vibration constantly, dispel hotly and out of shape, reduce the noise , improve the precision of localization of NC lathe , repeat precision , working dependability , stability , precision keeping, world a lot of country carr
