【正文】 ontrol lathe At present, the advanced manufacturing technology in the world is rising constantly, suchapplication of technology as ultrafast cutting , ultraprecision processing ,etc., the rapid development of the flexible manufacturing system and integrated system of the puter one is constant and ripe, have put forward higher demand to the process technology of numerical the numerical control lathe is being developed in several following directions.（1）.The speed and precision at a high speed , high accuracy are two important indexes of the numerical control lathe , it concerns directly that processes efficiency and product present, numerical control system adoptfigure number, frequency high processor, in order to raise basic operation speed of , adopt the super largescale integrated circuit and many microprocessors structure, in order to improve systematic data processing ability , namely improve and insert the speed and precision of mending the straight line motor and urge the straight line of the lathe workingbench to be servo to enter to the way directly, it is quite superior that its responds the characteristic at a high speed and feedforward control technology , make it lag behind error reduce greatly , thus improve the machining accuracy cut in corner not to meet ultrafast demand that process, numerical control lathe adopt main shaft motor and lathe structure form that main shaft unite two into one, realize frequency conversion motor and lathe main shaft integrate , bearing , main shaft of electrical machinery adopt magnetism float the bearing , liquid sound pigeonhole such forms as the bearing or the ceramic rolling bearing ,etc..At present, ceramic cutter and diamond coating cutter have already begun to get application.（2）.Multifunctional to is it change all kinds of machining centers 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 , 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 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 network , 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 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 breaking down , adopt the measure of shutting down , 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 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 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 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 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。One hundred sheets of storehouses adds the main shaft and changes one one hundred sheets of machining centers。Single axle , dual axle , three axle can change machining center , main shaft of case。Join the convenient one in order to improve the performance of urging and use intelligently, to the feedback control , adaptive operation , discerning automatically load selects models automatically , since carries on research whole definitely , the electrical m
