In 1952 the American Massachusetts Instituteof Technology has installed a set of experiments numerical controlssystem on a vertical milling machine, successfully realizessimultaneously controls the three axle the movement, it has become inthe world the first numerical control engine bed. Hereafter, startsfrom the 60's, other some industrial nation like Germany, Japan and soon develop one after another produces and uses the numerical controlengine bed. In 1974 the microprocessor directly used in the numericalcontrol engine bed, further promoted the numerical control engine bedpopularization application and vigorously develops. More and moreconsummates along with the numerical control engine bed function, thereliability and the performance are more and more high, it graduallytook on the more and more important role in the manufacturingindustry. Our country numerical control engine bed development was starts from1958, has experienced several dozens years development, after untilthe 80's have introduced country numerical control servo and theservosystem technology and so on the Japan, US, Spain, our countrynumerical control technology only then had the quantitive leap,gradually unfolded using the surface, the numerical control technologyindustry only then gradually formed the scale. As a result of the modern industry rapid development, the marketdemand changes more and more diverse, the multi- varieties, center thesmall batch even piecework holds the quite great proportion, theordinary engine bed has more and more not been able to satisfy modernprocessing craft and the enhancement labor productivity request. Ifthe equipment completely renews the replace, not only fund investmenttoo big, the cost too is high, moreover the original equipment willleave unused creates the enormous waste. Now science and technologydevelopment very quick, specially the micro electron technology andthe computer technology development is quicker, applies on thenumerical control system, it both can enhance the engine bed theautomaticity, and can increase the processing precision, therefore themost economical means are carry on the ordinary engine bed thenumerical control transformation. Like this already may enhance theprocessing productivity, the improvement processing craft, but alsomay reduce the fund investment, reduces worker's labor intensity,reduces orders the new numerical control engine bed the deliveryperiod. The practice already the certificate conventional latheeconomy numerical control transformation had the significant actualvalue, for this, old was having the lathe to progress the goodnumerical control transformation to have the better market prospect. 關(guān)鍵詞：Economy numerical control lathe, digital computer, crosswisetransformation 中文摘要 國外利用數(shù)字計算機進行控制加工是從40年代開始的。1952年美國麻省理工學院在一臺立式銑床上裝了一套試驗性的數(shù)控系統(tǒng)，成功地實現(xiàn)同時控制三軸的運動，它成了世界上第一臺數(shù)控機床。此后，從60年代開始，其他一些工業(yè)國家如德國、日本等陸續(xù)地開發(fā)生產(chǎn)及使用數(shù)控機床。1974年微處理機直接用于數(shù)控機床，進一步促進了數(shù)控機床的普及應(yīng)用和大力發(fā)展。隨著數(shù)控機床的功能越來越完善，可靠性和性能越來越高，它在制造業(yè)中逐漸擔當了越來越重要的角色。 我國數(shù)控機床的研制是從1958年開始的，經(jīng)歷了幾十年的發(fā)展，直至80年代后引進了日本、美國、西班牙等國數(shù)控伺服及伺服系統(tǒng)技術(shù)后，我國的數(shù)控技術(shù)才有質(zhì)的飛躍，應(yīng)用面逐漸鋪開，數(shù)控技術(shù)產(chǎn)業(yè)才逐步形成規(guī)模。 由于現(xiàn)代工業(yè)的飛速發(fā)展，市場需求變的越來越多樣化，多品種、中小批量甚至單件生產(chǎn)占有相當大的比重，普通機床已越來越不能滿足現(xiàn)代加工工藝及提高勞動生產(chǎn)率的要求。如果設(shè)備全部更新替換，不僅資金投入太大，成本太高，而且原有設(shè)備的閑置又將造成極大的浪費。如今科學技術(shù)發(fā)展很快，特別是微電子技術(shù)和計算機技術(shù)的發(fā)展更快，應(yīng)用到數(shù)控系統(tǒng)上，它既能提高機床的自動化程度，又能提高加工精度，所以最經(jīng)濟的辦法就是進行普通機床的數(shù)控改造。這樣既可以提高加工生產(chǎn)率，改善加工工藝，還可以減少資金投入，減輕工人的勞動強度，縮短訂購新的數(shù)控機床的交貨周期時間。實踐已經(jīng)證明普通車床的經(jīng)濟型數(shù)控改造具有重大的實際價值，為此，在舊有車床上進行數(shù)控改造有著較好的市場前景。 關(guān)鍵詞：經(jīng)濟型數(shù)控車床,數(shù)字計算機,橫向改造
