英文摘要 Overseas carries on the control processing using the digital computeris starts from the 40s. 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 60s, 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 80s have introduced country numerical control servo and theservosystem technology and so on the Japan, US, Spain, our countrynumerical control ntstechnology 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 workers labor intensity,reduces orders the new numerical control engine bed the deliveryperiod. The ntspractice 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. 关键词： Economy numerical control lathe, digital computer, crosswisetransformation 中文摘要 国外利用数字计算机进行控制加工是从 40 年代开始的。 1952 年美国麻省理工学院在一台立式铣床上装了一套试验性的数控系统，成功地实现同时控制三轴的运动，它成了世界上第一台数控机床。此后，从 60 年代开始，其他一些工业国家如德国、日本等陆续地开发生产及使用数控机床。 1974 年微处理机直接用于数控机床，进一步促进了数控机床的普及应用和大力发展。随着数控机床的功能越来越完善，可靠性和性能越来越高，它 在制造业中逐渐担当了越来越重要的角色。 我国数控机床的研制是从 1958 年开始的，经历了几十年的发展，直至 80年代后引进了日本、美国、西班牙等国数控伺服及伺服系统技术后，我国的数控技术才有质的飞跃，应用面逐渐铺开，数控技术产业才逐步形成规模。 由于现代工业的飞速发展， 市场需求变的越来越多样化，多 品种、中小批量甚至单件生产占有相当大的比重，普通机床已越来越不能满足现代加工工艺及提高劳动生产 率的要求。如果设备全部更新替换，不仅资金投入太大，成本太高，而且原有设备的闲置又将造成极大的浪费。如今科学技术发展很快，特别是微电子技术和计算机技术的发展更快，应用到数控系统上，它既能提高机床的自动化程度
