【正文】 craft back to existence as well as some problem of aspect needs to proceed orderly other solve. The shorting is that finished cost is high, correct cutter sigmatism have paratively high demand, can not have used big cutters， need to have the plicated puter programming technology to be used for support, equipment running cost height. Two, the high speed processing a mould39。 high speed treating apply to the beneficial result that the mould processes 1) fleetness rough process and half finish machining, improve treating efficiency。 The IT industry year increases % speed equally exceeding 20， the need to the mould accounts for 20 of mould marketplace %.2020 annual Chinese machine tools implements industry output value. will continue to increase. Our country mould fabrication market potential is enormous. The basis data counts， in recent years， our country mould year gross output value reaches 3 billion U. S. dollar， entrance exceeds 1 billion U. S. dollar， exceed 100 million U. S. dollar outlet. Increase by from 25% to increase to 2020 50% of 1995. The expert foretells that abroad: Asia portion being occupied by in mould fabrication in the whole world, will from 25% to increase to 2020 50% of 1995. Chinese mould industry has been expanding by leaps and bounds， has formed east China and two big South China bases, and has expanded gradually arriving at other province. In 2020 (Shandong， Anhui， Sichuan) in 1996， mould manufacturing industry output value annual average growth 14% , grows by 25% in 2020. In 2020 our country mould output value is 45 billion RMB. The gross product place occupies the world the 3rd， exports a mould increases % pared to last year 336,800,000 U. S. dollar. But, contents low our country technology moulds already pile up in excess of requirement， very most support of accurate， plicated top grade mould imports. Every year the entrance mould exceeds 1 billion U. S. dollar. Exceed 100 million U. S. dollar outlet. Precise mould accuracy requires that 3 mu ms， largescale moulds require that 8000 satisfied kN agree well with model force injection machine request in 2 ~； The minitype mould needs the request satisfying the diameter 1 mm silent stock tube. At present, adopt quickcutting to produce a mould already being the general trend that the mould makes, a few moulds have produced a manufacturer in abroad， highspeed machine tool large area has substituted the electric spark machine tool， quickcutting has improved the mould efficacy greatly. Machine tool enterprise aims at mould manufacturing enterprises， some treating centres 60% all above of the machine tool producing a factory sells treating enterprise to a mould. The mould fabrication enterprise substituting the electric spark finish machining mould gradually in abroad has adopt quickcutting already monly , quickcutting has produced a mould already being the general trend that the mould makes gradually， has improved the mould efficacy and mass greatly. Adopt quickcutting to replace electric spark producing a mould , can get on the stick obviously , improves mould accuracy， life time growing. 2 high speed processes application in making in the mould quickcutting merit: 1) cutter high rotation rate and the machine tool height enter be given to and high acceleration， improve metal excision rate greatly。我們希望，通過(guò)各方面的努力，在市場(chǎng)需求的推動(dòng)下，通過(guò)技術(shù)進(jìn)步，像汽車(chē)、機(jī)床、家電一樣 , 在不遠(yuǎn)的將來(lái)，我國(guó) 不 但要成為模具生產(chǎn) 大 國(guó)，而且要成為模具生產(chǎn)強(qiáng)國(guó)。 1）由于高速加工模具的歷史比較短，缺乏應(yīng)用經(jīng)驗(yàn)積累； 2）對(duì)高速切削工藝研究比較少，投入不夠，立項(xiàng)比較困難； 3）缺少高速切削數(shù)據(jù)庫(kù)或手冊(cè)， 目 前還是空白； 4）模具生產(chǎn)廠(chǎng)家對(duì)高速切削的認(rèn)識(shí)不夠，缺乏長(zhǎng)期效益的分析對(duì)比； 切削自動(dòng)編程軟件 CAM軟件。 2 刀具 1）國(guó)產(chǎn)刀具還不能夠適應(yīng)高速切削的應(yīng)用，特別是高速硬切削光整加工。 或者采用螺旋線(xiàn)或斜向進(jìn)給切入； 3) 恒定每刃進(jìn)給，提高質(zhì) 量 ，延長(zhǎng)刀具壽命； 4)輪廓加工保持在水平面上等。而國(guó)內(nèi)企業(yè)一般選用零件材質(zhì)有一定的標(biāo)準(zhǔn)，所使用的零件材料，特別是能用 高 速加工的零件材質(zhì)， 一 般會(huì)局限在某些零件材料范圍 內(nèi)，這對(duì)我們應(yīng)用高速加 工 技術(shù)也提供了有利的條件，會(huì)在較少的加 工 材料范圍 內(nèi)應(yīng)用。 ， 目 前應(yīng)用最多的是 HSK 刀柄，熱壓裝夾刀具。選擇足夠高速度的機(jī)床硬切削模具精加工。 但是，進(jìn) 口 刀具的昂貴價(jià)格也阻礙高速切削模具的重要因素。聚晶立方氮化硼 (PCBN)刀片，其硬度可達(dá)3500~4500HV。 2 五軸機(jī)床的應(yīng)用增加趨勢(shì) 1）加工路線(xiàn)靈活，表面形狀復(fù)雜； 2）加工 范圍大 ，適合多種類(lèi)型模具加工； 3）切削 條件好，減少刀具磨損，提高刀具壽命； 3 購(gòu)買(mǎi) CAD/CAM 軟件和高速機(jī)床配套 據(jù)統(tǒng)計(jì)，每年有幾十億美元用于進(jìn) 口 機(jī)床， 大 部分電加工機(jī)床和高速機(jī)床需要進(jìn) 口 。模具行業(yè)今后幾年年均有 50 億元的固定 資產(chǎn)投入，其中 80%是購(gòu)買(mǎi)模具加 工設(shè)備 ，也就是說(shuō)每年有 40 億元人民幣要購(gòu)買(mǎi)金切機(jī)床。還存在機(jī)床、刀具 、 工藝以及其他方面的一些問(wèn)題需要逐步解決。 機(jī)床 企業(yè)瞄準(zhǔn)模具生產(chǎn)企業(yè)，有的加 工中心生產(chǎn) 廠(chǎng) 機(jī)床的 60%以上賣(mài)給模具加工企業(yè) 。但是，我國(guó)技術(shù)含量低的模具已供過(guò)于求，精密、復(fù)雜的高檔模具很大 部分依靠進(jìn)口。國(guó)外專(zhuān)家預(yù)言：亞洲在全球模具制造中占據(jù)的份額，將從 1995 年的 25%增加至 2020年的 50%。 2020 年中 國(guó) 機(jī)床工具工業(yè)產(chǎn)值將繼續(xù)增長(zhǎng)。附件 1：外文資料翻譯譯文 高速加工和現(xiàn)代模具制造 一、 概述 1 目前模具制造的發(fā)展現(xiàn)狀和趨勢(shì) 模具作為重要的工藝裝備，在消費(fèi)品、電器電子、汽車(chē)、飛機(jī)制造等工業(yè)部門(mén)中 ，占有舉足輕重的地位。 指導(dǎo)教師評(píng)語(yǔ)： 簽名： 年 月
