【正文】 nds of autonomy function, thus may realize long time nobody to safeguard the processing. advantage which derives by above five. For example: Reduced worker39。 The engine bed numerical control transforms shallowly discusses First, numerical control system development brief history and tendency In 1946 was born in the world the first electronic accounting machine, this indicated the humanity created has been possible to strengthen and partially to replace the mental labor the tool. It with the humanity these which in the agriculture, the industry society created only is strengthens the physical labor the tool to pare, got up the quantitive leap, entered the information society for the humanity to lay the foundation. After 6 years, namely in 1952, puter technology applied to the engine bed on, were born the first numerical control engine bed in US. From this time on, the traditional engine bed has had the archery target change. Since nearly half century, the numerical control system has experienced two stages and six generation of development. , numerical control (NC) stage (1,952 ~ in 1970) The early puter operating speed is low, was not big to then science putation and the data processing influence, but could not adapt the engine bed realtime control request. The people can not but use numeral logic circuit to build to bee an engine bed special purpose puter to take the numerical control system, is called the hardware connection numerical control (HARDWIRED NC), Jian Chengwei numerical control (NC). Along with the primary device development, this stage has had been through repeatedly three generations, namely 1952 first generation of electron tube。 如：降低了工人的勞動強度，節(jié)省了勞動力（一個人可以看管多臺機床），減少了工裝，縮短了新產(chǎn)品試制周期和生產(chǎn)周期，可對市場需求作出快速反應(yīng)等等。 加工零件的精度高，尺寸分散度小，使裝配容易，不再需要 修配 。 由于計算機有高超的運算能力，可以瞬時準(zhǔn)確地計算出每個坐標(biāo)軸瞬時應(yīng)該運動的運動量，因此可以復(fù)合成復(fù)雜的曲線或曲面。 （ 2）引入專家系統(tǒng)指導(dǎo)加工 將熟練工人和專家的經(jīng)驗，加工的一般規(guī)律和特殊規(guī)律存入系統(tǒng)中，以工藝參數(shù)數(shù)據(jù)庫為支撐，建立具有人工智能的專家系統(tǒng)。遠(yuǎn)程通訊，遠(yuǎn)程診斷和維修將更加普遍。所以我們?nèi)粘Ｖv的 數(shù)控 ，實質(zhì)上已是指 計算機數(shù)控 了 。數(shù)控系統(tǒng)從此進(jìn)入了基于 PC的階段。而且當(dāng)時的小型機可靠性也不理想。于是將它移植過來作為數(shù)控系統(tǒng)的核心部件，從此進(jìn)入了計算機數(shù)控（ CNC）階段（把計算機前 面應(yīng)有的 通用 兩個字省略了）。 、數(shù)控（ NC）階段（ 195
