【正文】 ngle processing, causes 5 processings and 5 axis processings may realize on the identical Taiwan engine bed, but also may realize the inclined plane and the back taper hole processing. German DMG Corporation displays the DMUVoution series processing center, may clamp the next 5 processings and 5 axis linkage processing in an attire, may by the CNC systems or CAD/CAM which are controled deract or inderact. intellectualizations, open style, the work bees the contemporary numerical control system development the main tendency The 21st century numerical control equipments will be has certain intellectualized 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。 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。s STEP Tools Corporation is in the global scope the manufacturing industry data exchange software exploiter, he already developed has served as the numerical control engine bed processing exchange of information the super model (Super Model), its goal was with the unification standard description all processing process. At present this kind of recent data exchange form already in has provided SIEMENS, FIDIA as well as on the European OSACANC numerical control system prototype prototype has carried on the confirmation. 2 pair of our country numerical control technology and industrial development basic estimate Our country numerical control technology start in 1958, the near 50 year development course might divide into 3 stages approximately: First stage from 1958 to 1979, namely enclosed type development phase. In this stage, as a result of the overseas technical blockade with our country39。s realistic demand. Although from longitudinal looked our country39。 The reliability is not high, the mercialized degree is insufficient。s living standard, moreover also may alleviate our country employment the pressure, the safeguard society39。 Certainly, does not have the scale China39。 2. 外文原文應(yīng)以附件的方式置于譯文之后。s head the date. In the precise and advanced equipment research and development aspect, must emphasize produces, studies, grinds as well as enduser39。 Next looked safely from the national defense that, the Western developed country all lists as the precise and advanced numerical control product the national strategic material, realizes to our countr y embargoes and limits, “the Toshiba event” and “Cox reported” is the best illustration. development strategies Embarks from our country fundamental realities of the country angle, take the national strategic demand and the national economy market demand as the guidance, take enhances our country to make the equipment industry synthesis petitive ability and the industrial production level as the goal, with the system method, the choice can lead the 21st century initial period our country to make the key technologies as well as the support industrial production development support technology, the necessary technology which the equipment industry development promotes takes the research development the content, the realization manufacture equipment industry cross leap type development. Emphasized the market demand is the guidance, namely by the numerical control terminal product primarily, by the plete machine (for example quantity big surface broad numerical control lathe, milling machine, high speed high fine high performance numerical control engine bed, model digitization machinery, key profession essential equipment and so on) leads the numerical control industry the development. Key solution numerical control system and correlation function part (digitization servosystem and electrical machinery, high speed electricity main axle system and new equipment appendix and so on) reliable and scale of production question. Does not have the scale not to be able to have the redundant reliable product。 Numerical control technology application domain development dynamics is not strong。 The function part specialization production level and plete set ability are low。s numerical control industry base c. Has established a numerical control research, the development, managerial talent39。s ONC numerical control system standard frame research and the formulation. about numerical control standard The numerical control standard is the manufacturing industry informationization development one tendency. The numerical control technology is born after 50 year exchanges of information all is based on the ISO6983 standard, how namely uses the G, M code to describe the (how) processing, its substantive characteristics faces the processing process, obviously, he has more and more not been able to satisfy modern numerical control technology high speed the need to develop. Therefore, on international is studying and formulates one kind of new CNC system standard ISO14649(STEPNC), its goal is provides one kind not to rely on the concrete system neutral mechanism, can describe in the product entire life cycle unified data model, thus realizes the entire manufacture process, and even each i
