數(shù)控機(jī)床一開(kāi)始就選定具有復(fù)雜型面的飛機(jī)零件作為加工對(duì)象，解決普通的加工方法難以解決的關(guān)鍵。數(shù)控加工的一大特點(diǎn)是用穿孔帶（或磁帶）控制機(jī)床進(jìn)行自動(dòng)加工。由于飛機(jī)、火箭和發(fā)動(dòng)機(jī)零件各有不同的特點(diǎn)：飛機(jī)和火箭的零、構(gòu)件尺寸大、型面復(fù)雜；發(fā)動(dòng)機(jī)零、構(gòu)件尺寸小、精度高。因此飛機(jī)、火箭制造部門(mén)和發(fā)動(dòng)機(jī)制造部門(mén)所選用的數(shù)控機(jī)床有所不同。在飛機(jī)和火箭制造中以采用連續(xù)控制的大型數(shù)控銑床為主，而在發(fā)動(dòng)機(jī)制造中既采用連續(xù)控制的數(shù)控機(jī)床，也采用點(diǎn)位控制的數(shù)控機(jī)床（如數(shù)控鉆床、數(shù)控鏜床、加工中心等）。
工序集中
數(shù)控機(jī)床一般帶有可以自動(dòng)換刀的刀架、刀庫(kù)，換刀過(guò)程由程序控制自動(dòng)進(jìn)行，因此，工序比較集中。工序集中帶來(lái)巨大的經(jīng)濟(jì)效益：
⑴減少機(jī)床占地面積，節(jié)約廠房。
⑵減少或沒(méi)有中間環(huán)節(jié)（如半成品的中間檢測(cè)、暫存搬運(yùn)等），既省時(shí)間又省人力。
自動(dòng)化
數(shù)控機(jī)床加工時(shí)，不需人工控制刀具，自動(dòng)化程度高。帶來(lái)的好處很明顯。
⑴對(duì)操作工人的要求降低：
一個(gè)普通機(jī)床的高效工，不是短時(shí)間內(nèi)可以培養(yǎng)的，而一個(gè)不需編程的數(shù)控工培養(yǎng)時(shí)間極短（如數(shù)控車(chē)工需要一周即可，還會(huì)編寫(xiě)簡(jiǎn)單的加工程序）。并且，數(shù)控工在數(shù)控機(jī)床上加工出的零件比普通工在傳統(tǒng)機(jī)床上加工的零件精度要高，時(shí)間要省。⑵降低了工人的勞動(dòng)強(qiáng)度：數(shù)控工人在加工過(guò)程中，大部分時(shí)間被排斥在加工過(guò)程之外，非常省力。
⑶產(chǎn)品質(zhì)量穩(wěn)定：數(shù)控機(jī)床的加工自動(dòng)化，免除了普通機(jī)床上工人的疲勞、粗心、估計(jì)等人為誤差，提高了產(chǎn)品的一致性。
⑷加工效率高：數(shù)控機(jī)床的自動(dòng)換刀等使加工過(guò)程緊湊，提高了勞動(dòng)生產(chǎn)率。
柔性化高
傳統(tǒng)的通用機(jī)床，雖然柔性好，但效率低下；而傳統(tǒng)的專(zhuān)機(jī)，雖然效率很高，但對(duì)零件的適應(yīng)性很差，剛性大，柔性差，很難適應(yīng)市場(chǎng)經(jīng)濟(jì)下的激烈競(jìng)爭(zhēng)帶來(lái)的產(chǎn)品頻繁改型。只要改變程序，就可以在數(shù)控機(jī)床上加工新的零件，且又能自動(dòng)化操作，柔性好，效率高，因此數(shù)控機(jī)床能很好適應(yīng)市場(chǎng)競(jìng)爭(zhēng)。
At the beginning of CNC machine tools, aircraft parts with complex surfaces were selected as processing objects to solve the key problems that ordinary machining methods are difficult to solve. A major feature of NC machining is the use of perforated tape(or tape) control machine tools for automatic processing. Due to the different characteristics of aircraft, rockets and engine parts: zero aircraft and rockets, large components, and complex surfaces; Engine zero, small component size, high precision. Therefore, the CNC machine tools used by the aircraft, Rocket manufacturing departments and engine manufacturing departments are different. In aircraft and rocket manufacturing, large-scale CNC milling machines with continuous control are used, while in engine manufacturing, CNC machine tools with continuous control are also used(such as CNC drilling machines, CNC boring machines, and machining centers).
Process concentration
CNC machine tools are generally equipped with knives and tool libraries that can be automatically changed. The process of changing knives is automatically controlled by the program. Therefore, the process is relatively concentrated. Process concentration brings great economic benefits:
(1) Reduce the area of machine tools and save factories.
(2) The reduction or absence of intermediate links(such as intermediate testing of semi-finished products, temporary storage and handling, etc.) saves both time and manpower.
automation
CNC machine tool processing, no manual control tool, high degree of automation. The benefits are obvious.
(1) Reduced requirements for operators:
The efficient work of an ordinary machine tool can not be cultivated in a short period of time, and the training time of a CNC worker who does not require programming is extremely short(for example, a CNC driver needs a week, and a simple processing program is also written). Moreover, the parts processed by CNC workers on CNC machine tools are more accurate than those processed by ordinary workers on traditional machine tools, and the time must be saved. (2) Reduced labor intensity of workers: CNC workers in the processing process, most of the time is excluded from the processing process, very labor-saving.
(3) Product quality stability: The automation of NC machine tools avoids the fatigue, carelessness, and human error of ordinary machine tools, and improves product consistency.
(4) High efficiency of machining: The automatic changing knife of CNC machine tool makes the processing process compact and improves labor productivity.
Flexible and high
Traditional universal machine tools, although flexible, but inefficient; Although the efficiency of the traditional special plane is very high, the adaptability to the parts is poor, the rigidity is large, and the flexibility is poor. It is difficult to adapt to the frequent modification of products brought about by fierce competition under the market economy. As long as the program is changed, new parts can be processed on the CNC machine tool, and it can be automated, flexible, and efficient. Therefore, the CNC machine tool can adapt well to market competition.
