3—5 個(gè)運(yùn)動(dòng)坐標(biāo)軸，常見的是三個(gè)直線運(yùn)動(dòng)坐標(biāo)軸和一個(gè)回轉(zhuǎn)運(yùn)動(dòng)坐標(biāo)軸（回轉(zhuǎn)工作臺(tái)） ，它能在工件一次裝夾完成除安裝面和頂面以外的其余 4 個(gè)面的加工，最適合加工箱體類工件。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(jià)格高。立式加工中心，立式加工中心主軸的軸線為垂直設(shè)置，其結(jié)構(gòu)多為固定立柱式，工作臺(tái)為十字滑臺(tái)，適合加工盤類零件，一般具有 3

軸）來加工螺旋類零件。立式加工中心結(jié)構(gòu)簡(jiǎn)單，占地面積小，價(jià)格低，配備各種附件后，可進(jìn)行大部分工件的加工。大型龍門式加工中心，主軸多為垂直設(shè)置，尤其使用于大型或形狀復(fù)雜的工件，像航空、航天工業(yè)及大型汽輪機(jī)上的某些零件的加工都需要用這類多坐標(biāo)龍門式加工中心。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(gè)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。（2）按工藝用途分類有：鏜銑加工中心，分為立式樘銑加工中心、臥式樘銑加工中心和龍門樘銑加工中心。其加工工藝以樘銑為主，用于箱體，殼體以及各種復(fù)雜零件特殊曲線和曲面輪廓的多工序加工，適合多品種小批量生產(chǎn)。復(fù)合加工中心，主要指五面復(fù)合加工，主軸頭可自動(dòng)回轉(zhuǎn)，進(jìn)行立，臥加工，在主軸自動(dòng)回轉(zhuǎn)后，在水平和垂直方向?qū)崿F(xiàn)知道變換。（3）按特殊功能分類有：?jiǎn)喂ぷ髋_(tái)、雙工作臺(tái)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(kù)加主軸換刀加工中心；刀庫(kù)接寫手加主軸換刀加工中心；刀庫(kù)加機(jī)械手加雙主軸轉(zhuǎn)塔加工中心。3、當(dāng)今數(shù)控機(jī)床的發(fā)展趨勢(shì)：目前，世界先進(jìn)制造技術(shù)不斷興起，超高速切削、超精密加工等技術(shù)的應(yīng)用，柔性制造系統(tǒng)的迅速發(fā)展和計(jì)算機(jī)集成系統(tǒng)的不斷成熟，對(duì)數(shù)控加工技術(shù)提出了更高的要求。當(dāng)今數(shù)控機(jī)床正在朝著以下幾個(gè)方向發(fā)展。（1）.高速度、高精度化速度和精度是數(shù)控機(jī)床的兩個(gè)重要指標(biāo)，它直接關(guān)系到加工效率和產(chǎn)品質(zhì)量。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(yùn)算速度。同時(shí)，采用超大規(guī)模的集成電路和多微處理器結(jié)構(gòu)，以提高系統(tǒng)的數(shù)據(jù)處理能力，即提高插補(bǔ)運(yùn)算的速度和精度。并采用直線電動(dòng)機(jī)直接驅(qū)動(dòng)機(jī)床工作臺(tái)的直線伺服進(jìn)給方式，其高速度和動(dòng)態(tài)響應(yīng)特性相當(dāng)優(yōu)越。采用前饋控制技術(shù)，使追蹤滯后誤差大大減小，從而改善拐角切削的加工精度。為適應(yīng)超高速加工的要求，數(shù)控機(jī)床采用主軸電動(dòng)機(jī)與機(jī)床主軸合二為一的結(jié)構(gòu)形式，實(shí)現(xiàn)了變頻電動(dòng)機(jī)與機(jī)床主軸一體化，主軸電機(jī)的軸承采用磁浮軸承、液體動(dòng)靜壓軸承或陶瓷滾動(dòng)軸承等形式。目前，陶瓷刀具和金剛石涂層刀具已開始得到應(yīng)用。（2）.多功能化配有自動(dòng)換刀機(jī)構(gòu)(刀庫(kù)容量可達(dá) 100 把以上)的各類加工中心，能在同一臺(tái)機(jī)床上同時(shí)實(shí)現(xiàn)銑削、鏜削、鉆削、車削、鉸孔、擴(kuò)孔、攻螺紋等多種工序加工，現(xiàn)代數(shù)控機(jī)床還采用了多主軸、多面體切削，即同時(shí)對(duì)一個(gè)零件的不同部位進(jìn)行不同方式的切削加工。數(shù)控系統(tǒng)由于采用了多 CPU 結(jié)構(gòu)和分級(jí)中斷控制方式，即可在一臺(tái)機(jī)床上同時(shí)進(jìn)行零件加工和程序編制，實(shí)現(xiàn)所謂的“前臺(tái)加工，后臺(tái)編輯” 。為了適應(yīng)柔性制造系統(tǒng)和計(jì)算機(jī)集成系統(tǒng)的要求，數(shù)控系統(tǒng)具有遠(yuǎn)距離串行接口，甚至可以聯(lián)網(wǎng)，實(shí)現(xiàn)數(shù)控機(jī)床之間的數(shù)據(jù)通信，也可以直接對(duì)多臺(tái)數(shù)控機(jī)床進(jìn)行控制。（3）.智能化現(xiàn)代數(shù)控機(jī)床將引進(jìn)自適應(yīng)控制技術(shù)，根據(jù)切削條件的變化，自動(dòng)調(diào)節(jié)工作參數(shù)，使加工過程中能保持最佳工作狀態(tài)，從而得到較高的加工精度和較小的表面粗糙度，同時(shí)也能提高刀具的使用壽命和設(shè)備的生產(chǎn)效率。具有自診斷、自修復(fù)功能，在整個(gè)工作狀態(tài)中，系統(tǒng)隨時(shí)對(duì) CNC 系統(tǒng)本身以及與其相連的各種設(shè)備進(jìn)行自診斷、檢查。一旦出現(xiàn)故障時(shí)，立即采用停機(jī)等措施，并進(jìn)行故障報(bào)警，提示發(fā)生故障的部位、原因等。還可以自動(dòng)使故障模塊脫機(jī)，而接通備用模塊，以確保無人化工作環(huán)境的要求。為實(shí)現(xiàn)更高的故障診斷要求，其發(fā)展趨勢(shì)是采用人工智能專家診斷系統(tǒng)。（4）.數(shù)控編程自動(dòng)化隨著計(jì)算機(jī)應(yīng)用技術(shù)的發(fā)展，目前 CAD／CAM 圖形交互式自動(dòng)編程已得到較多的應(yīng)用，是數(shù)控技術(shù)發(fā)展的新趨勢(shì)。它是利用 CAD繪制的零件加工圖樣，再經(jīng)計(jì)算機(jī)內(nèi)的刀具軌跡數(shù)據(jù)進(jìn)行計(jì)算和后置處理，從而自動(dòng)生成 NC 零件加工程序，以實(shí)現(xiàn) CAD 與 CAM 的集成。隨著 CIMS 技術(shù)的發(fā)展，當(dāng)前又出現(xiàn)了 CAD／CAPP／CAM 集成的全自動(dòng)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(kù)獲得。（5）.可靠性最大化數(shù)控機(jī)床的可靠性一直是用戶最關(guān)心的主要指標(biāo)。數(shù)控系統(tǒng)將采用更高集成度的電路芯片，利用大規(guī)?；虺笠?guī)模的專用及混合式集成電路，以減少元器件的數(shù)量，來提高可靠性。通過硬件功能軟件化，以適應(yīng)各種控制功能的要求，同時(shí)采用硬件結(jié)構(gòu)機(jī)床本體的模塊化、標(biāo)準(zhǔn)化和通用化及系列化，使得既提高硬件生產(chǎn)批量，又便于組織生產(chǎn)和質(zhì)量把關(guān)。還通過自動(dòng)運(yùn)行啟動(dòng)診斷、在線診斷、離線診斷等多種診斷程序，實(shí)現(xiàn)對(duì)系統(tǒng)內(nèi)硬件、軟件和各種外部設(shè)備進(jìn)行故障診斷和報(bào)警。利用報(bào)警提示，及時(shí)排除故障；利用容錯(cuò)技術(shù)，對(duì)重要部件采用“冗余”設(shè)計(jì)，以實(shí)現(xiàn)故障自恢復(fù)；利用各種測(cè)試、監(jiān)控技術(shù)，當(dāng)生產(chǎn)超程、刀損、干擾、斷電等各種意外時(shí)，自動(dòng)進(jìn)行相應(yīng)的保護(hù)。（6）.控制系統(tǒng)小型化數(shù)控系統(tǒng)小型化便于將機(jī)、電裝置結(jié)合為一體。目前主要采用超大規(guī)模集成元件、多層印刷電路板，采用三維安裝方法，使電子元器件得以高密度安裝，較大規(guī)?？s小系統(tǒng)的占有空間。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(jìn)一步小型化。這樣可以方便地將它安裝在機(jī)床設(shè)備上，更便于對(duì)數(shù)控機(jī)床的操作使用。
