【正文】 ch 100m/min about. A lot of car factories in the world at present, including Shanghai General Motors Corporation of our country, adopt, substitute and make the lathe up with highspeed machining center production line part that make up already. HyperMach lathe of Company , CINCINNATI of . , enter , give pace to be most loud to reach 60m/min, it is 100m/min to be fast, acceleration reach 2g, the rotational speed of the main shaft has already reached 60 000r/min. Processing a thin wall of plane parts, spend 30min only, and same part general at a high speed milling machine process and take 3h, process and need 8h with ordinary milling machine。 The paces and acceleration of main shaft of dual main shaft lathes of Germany DMG Company reach 12* separately! 000r/mm and 1g. In machining accuracy, in the past 10 years, ordinary progression has accused of the machining accuracy of the lathe to already improve from 10μm to 5μm, accurate grades of machining center from 3 5μm, raise to 1 , and ultraprecision machining accuracy begin , enter getting nanometer already. In machining accuracy, the past 10 years, ordinary progression accuse of machining accuracy of lathe raise to 5μm , from 3 5μm accurate grades of machining center from 10μm already, improve to 1 , and the ultraprecision machining accuracy has already begun to enter nanometer ( )ly. In dependability, MTBF value of the foreign numerical co ntrol device has already reached above 6 000h, MTBF value of the servo system reaches above 30000h, demonstrate very high dependability . For realize at a high speed , high finish machining, related to it function part if electric main shaft , straight line electrical machinery get fast development, the application is further expanded . 5 axles link and process and pound and process the lathe to develop fast Adopt 5 axle link , to threedimensional curved surface processing of part , can cut with the best geometirc form of the cutter, not only highly polished, but also efficiency is improved by a large margin . It is generally acknowledged , a 5 axle gear beds of efficiency can equal 2 3 axle gear beds , use cubic nitrogen boron wait ultra hard material milling cutter go on at a high speed milling , sharpening , quenching hard steel at the part, 5 axle link , process constant 3 axle link , process , give play to high benefit. But go over because 5 axles link the numerical control system , plicated reason of host puter structure, price its link numerical control to be lathe several times higher than 3 axle, in addition programming technological difficulty relatively heavy , have restricted 5 axle gear beds of development. At present because of electric appearance of main shaft, make , realize 5 axle pound main shaft hair structure processed to link greatly simplify, it make difficulty and cost reduce by a large margin , numerical control price disparity of systems shrink. So promote pound main shaft head type 5 axle gear bed and pound development to process lathe (process the lathe including 5 ). At EMO2021 exhibition, new Japanese 5 of worker machine process lathe adopt pound main shaft hair, can realize 4 processing and arbitrary processing of angle of vertical plane, make 5 process and 5 axles are processed and can be realized at the same lathe, can also realize the inclined plane and pour the processing of the hole of awls . Company , DMG of Germany , exhibit DMUVoution series machining center , can put , insert , down 5 process and 5 axes link and process in one, can be controlled by CNC system or CAD/CAM controls directly or indirectly. intellectualizations, open style, the work turns into for the contemporary numerical control system development mainly hastens The 21st century numerical control equipments will be has certain intellectualized the system, the intellectualized content including in numerical control system each aspect: In order to pursue the processing efficiency and the processing quality aspect intellectualization, like processing process adaptive control, craft parameter automatic production。 In order to enhance the actuation performance and the use connection convenient intellectualization, like the feedforward control, the electrical machinery parameter autoadapted operation, the automatic diagnosis load automatic designation model, is automatic entire grades。 Simplification programming, simplification operation aspect intellectualization, like intellectualized automatic programming, intellectualized manmachine contact surface and so on。 Also has the intelligence to diagnose, the intelligent monitoring aspect content, the convenience system diagnosis and the service and so on In order to solve the traditional numerical control system seal and the numerical control application software industry production existence question. At present many countries conduct the research to the open style numerical control system, like US39。39。S NGC (The Next Generation WorkStation/Machine Control), European Economic Community39。39。s OSACA (Open System Architecture for Control within Automation Systems), Japan39。39。s OSEC (Open System Environment for Controller), China39。39。s ONC (Open Numerical Control System) and so on. The numerical control system will open already bees the numerical control system road of the future. The socalled open style numerical control system is the numerical control system development may in the unified movement platform, face the engine bed factory and the enduser, through the change, the increase or the tailor structure object (numerical control function), forms the seriation, and may conveniently integrates user39。39。s special application and the technical knack in the control system, the fast realization different variety, the different scale open style numerical control system, forms has the bright individuality famous brand g
