【正文】 of organization (a of capacity of storehouse can up to 100 of the above ) automatically to furnished with, can realize milling paring , boring and pares , bores such many kinds of processes as paring , turning , reaming , reaming , attacking whorl ,etc. to process at the same time on the same lathe , modern numerical control lathe adopt many main shaft , polyhedron cut also , carry on different cutting of way process to one different position of part at the same time. The numerical control system has because adopted many CPU structure and cuts off the control method in grades, can work out part processing and procedure at the same time on a lathe , realize socalled the front desk processes , the backstage supporter is an editor . In order to meet the needs of integrating the systematic one in flexible manufacturing system and puter, numerical control system have remote serial interface , can work , realize data munication , numerical control of lathe, can control many numerical control lathes directly too. （ 3） . Intelligent modern numerical control lathe introduce the adaptive control technology, according to cutting the change of the condition, automatic working parameter, make the processing course can keep the best working state , thus get the higher machining accuracy and roughness of smaller surface , can improve the service life of the cutter and production efficiency of the equipment at the same time . Diagnose by oneself , repair the function by oneself, among the whole working state, the system is diagnosed, checked by oneself to CNC system and various kinds of equipment linking to each other with it at any time. While breaking down , adopt the measure of shutting down etc. immediately , carry on the fault alarm, brief on position , reason to break down ,etc.. Can also make trouble module person who take off automatically , put through reserve module , so as to ensure nobody demand of working environment. For realize high trouble diagnose that requires , its development trend adopts the artificial intelligence expert to diagnose the system. （ 4） . Numerical control programming automation with the development of application 5 technology of the puter, CAD/CAM figure interactive automatic programming has already get more application at present, it is a new trend of the technical development of numerical control. It utilize part that CAD draw process pattern , is it calculate the trailing punishing to go on by cutter orbit data of puter and then, thus produce NC part and process the procedure automatically, in order to realize the integration of CAD and CAM. With the development of CIMS technology , the fullautomatic programming way in which CAD/CAPP/CAM integrates has appeared again at present, it, and CAD/CAM systematic programming great difference their programming necessary processing technology parameter needn39。 1 NC Technology Research current situation of NC lathe in our times Research and development process to such various kinds of new technologies as numerical control lathe , machining center , FMS , CIMS ,etc. of countries all over the world, linked to with the international economic situation closely. The machine tool industry has international economy to mutually promote and develop, enter 21 alert eras of World Affairs, the function that people39。 One hundred sheets of storehouses connects and writes hands to add the main shaft and change one hundred sheets of machining centers。 （ 2）、提高機床加工的精度和研究 為了提高加工中心的加工精度，不斷提高機床的剛度、減少振動，消除熱變形，降低噪聲，提高 NC機床的定位精度、重復(fù)精度、工作可靠性、穩(wěn)定性、精度保持性，世界很多國家都在進行機床熱誤差、機床運動及負(fù)載變形誤差的軟件補償技術(shù)研究，并采取精度補償、軟件補償?shù)却胧┘右愿纳?，有的已?jīng)可以使此類誤差消除 60%。 臥式加工中心，是指主軸軸線水平設(shè)置的加 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)。并采用直線電動機直接驅(qū)動機床工作臺的直線伺服進給方式，其高速度和動態(tài)響應(yīng)特性相當(dāng)優(yōu)越。具有自診斷、自修復(fù)功能，在整個工作 狀態(tài)中，系統(tǒng)隨時對 CNC系統(tǒng)本身以及與其相連的各種設(shè)備進行自診斷、檢查。數(shù)控系統(tǒng)將采用更高集成度的電路芯片，利用大規(guī)模或超大規(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。 5
