【正文】 目前，歐美國家非常重視 STEPNC 的研究，歐洲發(fā)起了 STEPNC 的 IMS 計(jì)劃(～ )。 重視新技術(shù)標(biāo)準(zhǔn)、規(guī)范的建立 關(guān)于數(shù)控系統(tǒng)設(shè)計(jì)開發(fā)規(guī)范 如前所述，開放式數(shù)控系統(tǒng)有更好的通用性、柔性、適應(yīng)性、 擴(kuò)展性，美國、歐共體和日本等國紛紛實(shí)施戰(zhàn)略發(fā)展計(jì)劃，并進(jìn)行開放式體系結(jié)構(gòu)數(shù)控系統(tǒng)規(guī)范 (OMAC、 OSACA、 OSEC)的研究和制定，世界 3 個(gè)最大的經(jīng)濟(jì)體在短期內(nèi)進(jìn)行了幾乎相同的科學(xué)計(jì)劃和規(guī)范的制定，預(yù)示了數(shù)控技術(shù)的一個(gè)新的變革時(shí)期的來臨。 為解決傳統(tǒng)的數(shù)控系統(tǒng)封閉性和數(shù)控應(yīng)用軟件的產(chǎn)業(yè)化生產(chǎn)存在的問題。 五軸聯(lián)動(dòng)加工和復(fù)合加工機(jī)床快速發(fā)展 采用 5 軸聯(lián)動(dòng)對(duì)三維曲面零件的加工，可用刀具最佳幾何形狀進(jìn)行切削，不僅光潔度高，而且效率也大幅度提高。這些都對(duì)加工裝備提出了高速、高精和高柔性的要求。s needs more and more already. For this reason, studying and making a kind of new CNC system standard ISO14649 (STEPNC) in the world, its purpose is to offer a kind of neutral mechanism not depending on the concrete system, can describe the unified data model in cycle of whole life of the products, thus realize the whole manufacture process, standardization of and even each industrial field product information. The appearance of STEPNC may be a revolution of the technological field of the numerical control, on the development and even the whole manufacturing industry of numerical control technology, will exert a farreaching influence. First of all, STEPNC puts forward a kind of brandnew manufacture idea, in the traditional manufacture idea, NC processes the procedures to all concentrate on individual puter. Under the new standard, NC procedure can be dispersed on Inter, this is exactly a direction of open , worked development of numerical control technology. Secondly, STEPNC numerical control system can also reduce and process the drawing (about 75%), process the procedure to work out the time (about 35%) and process the time (about 50%) greatly. At present, AmericanEuropean countries pay much attention to the research of STEPNC, Europe initiates IMS plan () of STEPNC. 20 CAD/CAM/CAPP/CNC users, manufacturers and academic organizations from Europe and Japan participated in this plan. STEP Tools Company of . is a developer of the data interchange software of manufacturing industry in the global range, he has already developed the super model (Super Model ) which accuses of information exchange of machine tooling by counting, its goal is to describe all processing courses with the unified norm. Such new data interchange form has already been verified in allocating the SIEMENS, FIDIA and European OSACANC numerical control at present. References： [1]胡占齊、董長雙、常興 .

Adopt largescale whole aluminium alloy method that blank pay empty make the wing recently, such largescale parts as the fuselage ,etc. e to substitute a lot of parts to assemble through numerous rivet , screw and other connection way, make the intensity , rigidity and dependability of the ponent improved. All these, to processing and equipping the demand which has proposed highspeed, high precise and high flexibility. According to EMO2020 exhibition situation, highspeed machining center is it give speed can reach 80m/min is even high , air transport petent speed can up to 100m/min to be about to enter. A lot of automobile fact
