【正文】 s spare parts are mostly the thin wall and thin muscle, rigidity very bad, material aluminium or aluminium alloy, in high to cut pace and cut strength very under the little situation only, could process these muscles , walls . Adopt largescale whole aluminium alloy blank method of pay empty make the wing recently, largescale parts such as the fuselage ,etc. e to substitute a lot of parts to assemble through numerous rivet , screw and other connection ways, make the intensity , rigidity and dependability of the ponent improved. All these requirement for processing and equipping and proposing highspeed , high and precise and high flexibility. According to EMO2021 exhibition situation, the highspeed machining center enters for the pace to can reach 80m/min , even high, air transport petent pace can reach 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。s livelihood plays a more and more important role, because these trade necessary digitization that equipped has already been the main trend of modern development. According to the technology of numerical control and equipment development trend in the world at present, its main research focus has the following several respect [1~4]. A highspeed , high finish machining technology and new trend equipped Efficiency , quality are subjects of the advanced manufacturing technology. At a high speed, high finish machining technology can raise the efficiency greatly, quality and grade to raise product, shorten production cycle and improve the petitive power of market. Japan carry technological research association classify their as one of the 5 loud modern manufacturing technologies first for this reason, learn (CIRP ) to confirm it as the centre in the 21st century to study one of the directions in international production engineering. In the field of car industry, produce 40 second when beat such as production of 300,000 / vehicle per 畢業(yè)設(shè)計(jì)說明書（論文） 36 year, and many variety process it is car that equip one of the key problems that must be solved。 (5)Transducer technology。 (3)Automatic control technology。s own numerical control technology and industry, and implement blockading and restrictive policy to our country in highgrade , precision and advanced key technology and equipment of numerical control. In a word, develop taking technology of numerical control as the 畢業(yè)設(shè)計(jì)說明書（論文） 35 core advanced manufacturing technology bee world all developed country , accelerate economic development already in a more costeffective manner, important route to improve the prehensive national strength and national position. Numerical control technology to go on technology that control with digital information to mechanical movement and working course, numerical control equipment whether represented by technology of numerical control new technology make industry and new developing infiltration electromechanics integrated product that form of manufacturing industry to tradition, . what is called digitization equip, its technological range covers a lot of fields: (1)Mechanical manufacturing technology。 本次畢業(yè)設(shè)計(jì)的順利完成離不開老師和同學(xué)的協(xié)助指導(dǎo) ,借此只言片語 ,對他們 熱心而無私的幫助表示衷心的感謝 ! 畢業(yè)設(shè)計(jì)說明書（論文） 33 參考文獻(xiàn) [1] 機(jī)械工程手冊編輯委員會編．機(jī)械設(shè)計(jì)手冊【 M】．第 3版．北京：機(jī)械工業(yè)出版社， 2021 [2] 機(jī)械工程手冊 電機(jī)工程手冊編輯委員會 .機(jī)械工程手冊 — 機(jī)械產(chǎn)品（二）[M].機(jī)械工業(yè)出版社 .1982 年 8月 .
