【正文】 Around the production and technology of numerical control process technology in bee type and the organization machine tool of parallel connection fast, robot melt machine tool, multifunction machine tool and such overall aspect with high speed electrical main shaft, the generator of straight line and software pensation precision etc. unit technology aspect priority break through. The rod department of parallel connection the new machine tool of numerical control of structure practical melts. This kind of fictitious number of axle controls machine tool to use the plexity of software, replace the plexity of the traditional organization of machine tool, have opened up the new field of the development of numerical control of machine tool.With puter assisted management and project database, Internet etc. support technology and intelligence for the production information of main part melt make policy system. For machining in magnanimity information stock with the handling of real time. Apply digitalization network technology, make machining entire system tend to resource control reasonably and apply efficiently.Since having adopted nerve network control technical, vague control technology and digitalization network technology, machining develops to the direction of fictitious productionZing on indicate , in show stage and future a time the system of numerical control and the machine tool of numerical control the development of technology will go to meet a new space, will surely reach a brandnew Zing Main with astonishing speed forward development on.。 The machine tool of numerical control and it form flexible production system can join with CAD, CAM, CAPP and MTS conveniently, to information integrated direction development。 emphasize the developing of reinforced unit technology, perfect。The intelligence of easier programming and easier operating aspect melts, as intelligent automatic programming intelligent manmachine interface etc.。1 ~ μ m. reliabilityHigh reliability denotes the reliability of the system of numerical control to be higher than the reliability of controlled equipment, but also do not be that reliability is merchandise high the more the more well, more than a quantity level, is still appropriately reliable, because being, get the restraint of price performance. For working every day the unmanned factory of two class, if ask to work continuously normally in 16 hours without reason block rate P( t) ＝ 99% above words, the average time MTBF of failure free operation of the machine tool of numerical control must be larger than 3000 hours. MTBF is larger than 3000 hours, for form from the machine tool of numerical control of different quantity unmanned chemical factory difference for mostly our, for a machine tool of numerical control, as main puter and the systematic failure rate of numerical control than is 10: the words of 1(numerical control reliable is a quantity level than main puter high). Right now, the MTBF of the system of numerical control will be larger than 33, hours, the MTBF of the main shaft and drive and installation in which of numerical control must be larger than onehundred thousands hours.Now abroad, the MTBF value of the installation of numerical control has reached 6000 hours more, actuating device reaches thirty thousands hours more. modular, intelligent, flexible and integrated modular, specialized, with personalizeThe structure of machine tool is modular, the function specialization of numerical control and the notable raising of machine tool of price performance accelerate optimization. For meet the characteristic of the much kind and small lot of numerical control of machine tool the structure of machine tool the modular function specialization of numerical control and the notable rising of machine tool of price performance accelerate optimization. Personalize is in last few years special obvious develop tendency. meltsThe intelligent every aspect that content includes in the system of numerical control:Melt to pursue the intelligence in the aspect of processing efficiency and processing quality, if from adaptive control, technology parameter is generated voluntarily。5 μ the processing precision of m and precise level machining center from 177。 precise processing precision have raised two quantity levels, super precision enter nanometer level ( microns) the rotary precision requirement of main shaft reach the micron of , processing circularity is the, processing surface Ra of surface roughness = micron etc.Precise melt is for meet the needs of high new technical development, is also for raising reliability, quality and the performance of ordinary mechanical and electrical products, reduce the workload its assembly so raise the needs of assembly efficienc
