本科生畢業(yè)論文（設(shè)計(jì)）開題報(bào)告論文題目：三坐標(biāo)數(shù)控銑床設(shè)計(jì)學(xué)生姓名： 專 業(yè)： 班 級(jí)： 指導(dǎo)教師： 一． 數(shù)控機(jī)床的產(chǎn)生與發(fā)展科學(xué)技術(shù)的不斷發(fā)展，對(duì)機(jī)械產(chǎn)品的質(zhì)量和生產(chǎn)率提出了越來越高要求。機(jī)械加工工藝過程的自動(dòng)化是實(shí)現(xiàn)上述要求的最主要的措施之一。它不僅提高產(chǎn)品的質(zhì)量、提高生產(chǎn)效率、降低生產(chǎn)成本、還能夠大大改善工人的勞動(dòng)條件。大批量的自動(dòng)化生產(chǎn)廣泛采用自動(dòng)機(jī)床、組合機(jī)床和專用機(jī)床以及專用自動(dòng)生產(chǎn)線，實(shí)行多刀、多工位同時(shí)加工，以達(dá)到高效率和高自動(dòng)化。但這些都屬于剛性自動(dòng)化，在面對(duì)小批量生產(chǎn)時(shí)并不是適用，因?yàn)樾∨可a(chǎn)需要經(jīng)常變化產(chǎn)品的種類，這就要求生產(chǎn)線具有柔性。而從某種程度上說，數(shù)控機(jī)床的出現(xiàn)正是很大的滿足了這一要求。1952 年，美國麻省理工學(xué)院成功的研制出一套三坐標(biāo)聯(lián)動(dòng)，利用脈動(dòng)乘法器原理的實(shí)驗(yàn)性數(shù)控系統(tǒng)，并把它裝在一臺(tái)立式銑床上。當(dāng)時(shí)用的電子元件是電子管，這就是世界上的第一臺(tái)數(shù)控機(jī)床。1959 年，數(shù)控裝置中廣泛采用電子管和印刷電路板，從而跨入數(shù)控的第二代。1965 年，出現(xiàn)了小規(guī)模集成電路，由于它體積小、功耗低，使數(shù)控系統(tǒng)的可靠性得以進(jìn)一步提高，從此數(shù)控發(fā)展到第三代。1970 年，在美國芝加哥國際機(jī)床展覽會(huì)上首次展出的數(shù)控系統(tǒng)采用計(jì)算機(jī)數(shù)控系統(tǒng)的機(jī)床，這便是數(shù)控的第四代。1974 年，出現(xiàn)了第五代數(shù)控系統(tǒng)（MNC 微處理機(jī)控制系統(tǒng)） 。我國是從 1958 年開始研制數(shù)控技術(shù)的，一直到 60 年代中期處于研制、開發(fā)時(shí)期。當(dāng)時(shí)，一些高等院校、科研單位研制出實(shí)驗(yàn)樣機(jī)，開發(fā)也是從電子管開始的。1965 年國內(nèi)開始研制晶體管數(shù)控技術(shù)。從 70 年代開始，數(shù)控技術(shù)在車、銑、鉆、鏜、磨、齒輪加工等領(lǐng)域全面展開，數(shù)控加工中心在上海、北京研制成功。在這一時(shí)期，數(shù)控線切割機(jī)床由于結(jié)果簡單、使用方便、價(jià)格低廉，在模具加工中得到了推廣。80 年代我國數(shù)控機(jī)床有了新的發(fā)展。90 年代以及接下來主要是向高檔數(shù)控機(jī)床發(fā)展數(shù)控技術(shù)是近代發(fā)展起來的一種自動(dòng)控制技術(shù)，是用數(shù)字化信號(hào)對(duì)機(jī)床運(yùn)動(dòng)及其加工過程進(jìn)行控制的一種方法。目前，在工業(yè)發(fā)達(dá)國家，無論在國防工業(yè)或民用工業(yè)，數(shù)控機(jī)床的應(yīng)用均已相當(dāng)普遍。數(shù)控機(jī)床已不在局限用來加工單件、小批以及形狀復(fù)雜的零件。數(shù)控加工中心機(jī)床，它是在一般數(shù)控鏜銑床上加裝刀庫和自動(dòng)換刀裝置?？梢赃B續(xù)地對(duì)零件進(jìn)行各加工面的銑、鉆、鉸、鏜以及攻絲的加工。減少了機(jī)床的占地面積，壓縮了半成品的庫存量，減少工序間的輔助時(shí)間，有效地提高了生產(chǎn)率?？梢灶A(yù)見，高級(jí)自動(dòng)化技術(shù)將進(jìn)一步證明數(shù)控機(jī)床的價(jià)值，并且正在更為廣闊的開拓著數(shù)控機(jī)床的應(yīng)用領(lǐng)域。二． 數(shù)控銑床的工作原理用數(shù)控銑床加工零件時(shí)，首先應(yīng)編制該零件的加工程序，這是數(shù)控銑床的工作指令。將加工程序輸入數(shù)控裝置，再由數(shù)控裝置控制機(jī)床主運(yùn)動(dòng)的變速、啟動(dòng)、停止、進(jìn)給運(yùn)動(dòng)的方向、速度和位移量，以及工件裝夾和冷卻潤滑的開關(guān)等動(dòng)作，使刀具與被加工零件以及其它輔助裝置嚴(yán)格按照加工工序規(guī)定的順序、運(yùn)動(dòng)軌跡加工出符合要求的零件。三． 數(shù)控銑床的組成數(shù)控銑床的組成：機(jī)床、數(shù)控裝置、控制介質(zhì)、伺服系統(tǒng)、測量裝置等組成。機(jī)床：三坐標(biāo)數(shù)控磨床應(yīng)具有更好的剛性和抗振性，因此床身采用密封式箱型結(jié)構(gòu)，在床身底內(nèi)腔填充泥芯和混凝土等阻尼材料，當(dāng)發(fā)生振動(dòng)時(shí)，利用阻尼材料之間的相對(duì)摩擦耗散振動(dòng)能量。數(shù)控裝置：數(shù)控裝置是數(shù)控機(jī)床的核心，是高技術(shù)密集型產(chǎn)品。它的功能是接受輸入裝置輸入的加工信息，經(jīng)過數(shù)控裝置的系統(tǒng)軟件對(duì)代碼進(jìn)行處理后，輸入相應(yīng)的指令脈沖，驅(qū)動(dòng)伺服系統(tǒng)，來控制機(jī)床的各個(gè)運(yùn)動(dòng)部件按規(guī)定的要求實(shí)現(xiàn)各個(gè)運(yùn)動(dòng)?？刂平橘|(zhì)：用于記載各種加工信息的載體，以控制機(jī)床的運(yùn)動(dòng)，實(shí)現(xiàn)零件的加工。數(shù)控介質(zhì)有穿孔帶、穿孔卡、磁帶及磁盤等，也可通過通信接口直接輸入所需各種信息。三坐標(biāo)數(shù)控銑床采用通信接口直接輸入所需各種信息。用鍵盤將加工程序直接鍵入，并且可在數(shù)碼顯示器或 CRT 顯示器上顯示出來。伺服系統(tǒng)：由伺服電動(dòng)機(jī)和伺服驅(qū)動(dòng)裝置組成，是數(shù)控系統(tǒng)的執(zhí)行部分。作用是把來自數(shù)控裝置的各種指令轉(zhuǎn)換成機(jī)床移動(dòng)部件的運(yùn)動(dòng)速度、運(yùn)動(dòng)方向和位移量。伺服系統(tǒng)要求有良好的快速響應(yīng)性能，進(jìn)給速度范圍要大，靈敏而準(zhǔn)確的跟蹤指令功能和轉(zhuǎn)速，在較大的范圍內(nèi)要求有良好的工作穩(wěn)定性。此數(shù)控銑床的驅(qū)動(dòng)元件為交流三相異步電動(dòng)機(jī)。測量裝置：是將床身的實(shí)際位置、速度等參數(shù)轉(zhuǎn)換成電信號(hào)反饋回?cái)?shù)控裝置。以校核執(zhí)行部件實(shí)際運(yùn)動(dòng)速度、方向和位移量，并使之與加工指令相一致。四． 設(shè)計(jì)題目及技術(shù)要求設(shè)計(jì)題目是三坐標(biāo)數(shù)控銑床設(shè)計(jì)。從總體布局和結(jié)構(gòu)形式，與普通銑床相似，主要還是由床身，主軸箱，刀架，進(jìn)給系統(tǒng)，液壓、冷卻、潤滑系統(tǒng)等部分組成。但是，由于動(dòng)力源采用了交流伺服電機(jī)，控制系統(tǒng)實(shí)現(xiàn)了 CNC，所以，使得主運(yùn)動(dòng)和進(jìn)給系統(tǒng)機(jī)械結(jié)構(gòu)大大簡化。尤其是進(jìn)給系統(tǒng)，與普通銑床的進(jìn)給系統(tǒng)有質(zhì)的區(qū)別，沒有傳統(tǒng)的進(jìn)給箱，板箱和掛輪架，而是直接由伺服電機(jī)通過滾球絲杠驅(qū)動(dòng)溜板和刀架，實(shí)現(xiàn)進(jìn)給運(yùn)動(dòng)。主要設(shè)計(jì)要求：三坐標(biāo)數(shù)控銑床，進(jìn)給精度 0.01mm，X、Y、Z 坐標(biāo)進(jìn)給速度2m/min，X、Y、行程 300mm,Z 行程 250mm，工作臺(tái)尺寸 420×300mm。五． 數(shù)控銑床各組成部分的分析1． X、Y 工作臺(tái)X、Y 工作臺(tái)的組成：X、Y 工作平臺(tái)傳動(dòng)機(jī)構(gòu)；X 向齒輪減速和滾珠絲杠傳動(dòng)方向（Y 向和 X 向相同） ；驅(qū)動(dòng)機(jī)構(gòu)：X、Y 向兩個(gè)電機(jī)。X、Y 工作臺(tái)的工作原理：通過控制 X、Y 向電機(jī)驅(qū)動(dòng)傳動(dòng)機(jī)構(gòu)，從而帶動(dòng) X、Y 工作平臺(tái)沿 X、Y 向運(yùn)動(dòng)。2． 主軸主軸部件包括主軸軸承、傳動(dòng)件和相應(yīng)的緊固件。主軸的端部是標(biāo)準(zhǔn)的。傳動(dòng)件如齒輪、帶輪等與一般的機(jī)械零件相同。機(jī)床主軸部件，三個(gè)方向的進(jìn)給及其它部件滾動(dòng)軸承，均采用潤滑脂潤滑。3． 導(dǎo)軌由運(yùn)動(dòng)和承導(dǎo)件組成。運(yùn)動(dòng)件：需要做直線運(yùn)動(dòng)的零部件。承導(dǎo)件：用于支承并限制運(yùn)動(dòng)件，使其只能按給定的要求和規(guī)定的方向作直線運(yùn)動(dòng)。設(shè)計(jì)中可采用滑動(dòng)導(dǎo)軌，對(duì)導(dǎo)軌要求有以下幾點(diǎn)：（1） 要有一定的導(dǎo)向精度。（2） 要有良好的耐磨性。（3） 要有足夠的剛度。（4） 有減小熱變形影響。（5） 要使運(yùn)動(dòng)輕便平穩(wěn)。（6） 要有一定的工藝性。主要用來支承和引導(dǎo)部件沿一定的軋道運(yùn)動(dòng)。要求導(dǎo)向精度高，耐磨性能好，足夠的剛度。本設(shè)計(jì)采用塑料導(dǎo)軌，鑲粘塑料導(dǎo)軌已廣泛用于數(shù)控機(jī)床。其摩擦系數(shù)小，且動(dòng)、靜摩擦差很小，能防止低速爬行現(xiàn)象；耐磨性、抗撕傷能力強(qiáng)；加工性和化學(xué)穩(wěn)定性好；工藝簡單，成本底；并有良好的自潤滑性和抗震性。塑料導(dǎo)軌多與淬硬剛導(dǎo)軌相配使用?；瑒?dòng)導(dǎo)軌間隙的調(diào)整：采相應(yīng)的用刮、磨結(jié)合面或加墊片的方法以獲得相應(yīng)的間隙；鑲條調(diào)整，這是側(cè)向間隙常用的調(diào)整方法，鑲條有直鑲條和斜鑲條兩種。采用矩形導(dǎo)軌，這種導(dǎo)軌的特點(diǎn)是結(jié)構(gòu)簡單，制造、檢驗(yàn)和修理較易，新導(dǎo)軌制造精度高，但導(dǎo)軌經(jīng)磨損后不能自動(dòng)補(bǔ)償，導(dǎo)向性不如三角形導(dǎo)軌好。三坐標(biāo)數(shù)控銑床采用貼塑導(dǎo)軌，這是一種金屬對(duì)塑料的摩擦形式。屬于滑動(dòng)摩擦導(dǎo)軌，導(dǎo)軌一滑移面上貼有一層抗磨軟帶，導(dǎo)軌的另一滑移面上貼為淬火磨削面，軟帶是以聚四氟乙烯為基材，添加合金粉和高氧化物的高分子復(fù)合材料。塑料導(dǎo)軌剛性好、動(dòng)靜摩擦系數(shù)差值小、耐磨性好、無爬行、抗振性好、化學(xué)的穩(wěn)定性好、維護(hù)修理方便、經(jīng)濟(jì)性好。塑料導(dǎo)軌和其它導(dǎo)軌相比，有以下特點(diǎn)：（1） 摩擦系數(shù)低而穩(wěn)定性比鑄鐵導(dǎo)軌低一個(gè)數(shù)量級(jí)；（2） 動(dòng)靜摩擦系數(shù)相近，運(yùn)動(dòng)平穩(wěn)性和爬行性能較鑄鐵導(dǎo)軌副好；（3） 吸收振動(dòng)具有良好的阻尼性，優(yōu)于接觸剛度較低的滾動(dòng)導(dǎo)軌和易于飄浮的靜壓導(dǎo)軌；（4） 耐磨性好，有自身潤滑作用，無潤滑油也能工作，灰塵磨粒的遷入性好；（5） 化學(xué)的穩(wěn)定性好，耐高、低溫、耐強(qiáng)酸強(qiáng)堿、強(qiáng)氟化劑及各種有機(jī)溶劑；（6） 維護(hù)修理方便，軟帶磨損后更易更換；（7） 經(jīng)濟(jì)性好、結(jié)構(gòu)簡單、成本低，約為滾動(dòng)導(dǎo)軌成本的 1/120。三成復(fù)合材料DU 導(dǎo)軌板成本的 1/4。三個(gè)方向的導(dǎo)軌副、滾珠絲杠副由自動(dòng)間隙潤滑油泵進(jìn)行定時(shí)潤滑，潤滑油泵安裝在立柱側(cè)面，通過分油器將潤滑油分送到各潤滑點(diǎn)上。4． 進(jìn)給裝置三坐標(biāo)數(shù)控銑床的進(jìn)給運(yùn)動(dòng)是數(shù)字控制的直接對(duì)象，不論點(diǎn)位控制還是連續(xù)控制，被加工工件的最后坐標(biāo)精度和輪廓精度都受到進(jìn)給運(yùn)動(dòng)的傳動(dòng)精度、靈敏度和穩(wěn)定性的影響。為此，要注意以下三點(diǎn)進(jìn)給運(yùn)動(dòng)要求：（1） 減少運(yùn)動(dòng)件的摩擦力。進(jìn)給系統(tǒng)雖有許多元件，但摩擦阻力主要來自絲杠和導(dǎo)軌。絲杠和導(dǎo)軌結(jié)構(gòu)的滾動(dòng)化是減少摩擦的重要措施之一。（2） 提高傳動(dòng)精度和剛度。在進(jìn)給系統(tǒng)中滾珠絲杠和支承結(jié)構(gòu)是決定其傳動(dòng)精度和剛度的主要部件，因此，必須首先保證它們的加工精度。（3） 減少運(yùn)動(dòng)慣量。進(jìn)給系統(tǒng)中每個(gè)元件的慣量對(duì)伺服機(jī)構(gòu)的啟動(dòng)和制動(dòng)特性都有直接的影響。尤其是處于高速運(yùn)轉(zhuǎn)的零件，其慣性的影響更大。5． 滾動(dòng)絲杠滾珠絲杠螺母副：在具有螺旋槽的絲杠螺母間裝有滾珠作為中間傳動(dòng)元件，以減少摩擦。當(dāng)絲杠與螺母相對(duì)運(yùn)動(dòng)時(shí)，滾珠沿螺旋槽向前滾動(dòng)，在絲杠上滾過數(shù)圈以后通過回程引導(dǎo)裝置，逐個(gè)地又滾回到絲杠與螺母之間，構(gòu)成一個(gè)閉和回路。它的優(yōu)點(diǎn)是：（1） 摩擦系數(shù)小，傳動(dòng)效率高，η 可達(dá) 0.92-0.96，所需傳動(dòng)轉(zhuǎn)矩小。（2） 靈敏度高，傳動(dòng)平穩(wěn)，不易產(chǎn)生爬行，隨動(dòng)精度和定位精度高。（3） 磨損小，壽命長，精度保持性好。（4） 可通過預(yù)緊和間隙消除措施提高軸向剛度和反向精度。（5） 運(yùn)動(dòng)具有可逆性，不僅可以將旋轉(zhuǎn)運(yùn)動(dòng)。6． 進(jìn)給伺服系統(tǒng)進(jìn)給伺服系統(tǒng)的組成：有驅(qū)動(dòng)控制單元、驅(qū)動(dòng)元件、機(jī)械傳動(dòng)部件、執(zhí)行件和檢測反饋環(huán)節(jié)等組成。驅(qū)動(dòng)控制單元和驅(qū)動(dòng)元件組成伺服驅(qū)動(dòng)系統(tǒng)；檢測元件與反饋電路組成檢測裝置亦稱檢測系統(tǒng)。進(jìn)給伺服系統(tǒng)中采用的驅(qū)動(dòng)裝置為直流伺服電機(jī)。7． 微處理器用來集中控制，分時(shí)處理數(shù)控系統(tǒng)的各項(xiàng)任務(wù)。單微處理器機(jī)構(gòu)的基本組成包括：微處理器和總線、存儲(chǔ) I/O 接口、MDI/CRT 接口、位置控制器、PC。微機(jī)控制系統(tǒng)的硬件設(shè)計(jì)主要就是上述幾個(gè)部分的具體設(shè)計(jì)。六

The concept may seem to be anything but new ,since we can alllook around us and see a myriad of products that utilize both mechanical and electronic dis- cipplines. Mechatronics,however ,specifically refers to a multidisciplined ,integrated approachto product and manufacturing system design .It represents the next generation of machines,robots ,and smart mechanisms necessary for carrying out work in a variety of environments-primarily ,factory automation ,office automation ,and home automation as show in Figure 1.By both implication and application ,mechatronics represents a new level of integration for advanced manufacturing technology and processes .The intent is to force a multidisciplinary approach to these syetems as well as to reemphasize the role of process understanding and control .This mechatronic approach is currently speeding up the already-rapid Japanese processfor trasforming ideas into products .Currently ,mechatronics describes the Japanese practice of useing fully intefrated teams of product designers ,manufactring, purchasing, and marketing personnel acting in concert witheach other to design both the product and the manufacturing syestem.The Japanese recognized that the future in producdtion innovation would belong to those who learned how to optimize the marriage beween eletronic and mechanical systems.They realized,inparticular ,that the need for this optimizatong would be most intense in application of advanced manufacturing and production systems where artificial intelligence ,expertsystems ,smart robots, and advanced manufacturing technology systems would create the next generation of tools to be used in the factory of the future.From the very beginnings of recorded time ,mechanical systems have found their way into everyaspect of our society .Our simplest mechanisms ,such as gears ,pulleys, springs,and wheeles.have provided the basis for our tools .Our electronics technology,on the other hand ,is completelytwentieth-century ,all of it created within the past 75 years.Until now ,electronics were included to enhance mechanical systems' performance ,but the emphasis remained on the mechanical product .There had never been any master plan on how the integration would be done .In the past ,it had been done on a case -by-case basis .More recently,however,because of the overwhelming advances in the world of electronics and its capability to physically simplify mechanical configurations ,the technical community began to reassessthe marriage between these two disciplines.The most obvious trend in the direction of mechatronic innovation can be observed in the automobile industry .There was atime when a car was primarily a mechanical marvel with afew electronic appendages.First came the starter motor ,and then the generator ,each making the original product a bit better than it was before .Then came solid-state electronics,and suddenly the mechanical marvelbecame an electro-mechanical marvel .Today's machine is controlled by microprocessors ,built byrobots ,and fault-an-alyzed by a computer connected to its “external interface connector“.Automotive mechanical engineers are no longer the masters of their creations.The process that describes the evolution of the autimibile is somewhat typical of other productds in our society.Electronics has repeatedly improved the performance of mechanical systems ,but that innovation has been more by serendipity than by design .And that is the essenceof mechatronica the preplanned application of ,and the efficient integration of,mechanicaland electronics technology to create an optimum product.A recent U.S. Department of Commerce report entitled “JTECH Panel Report on Mechatronics in Japan“compared U.S and Japanese research and development trends in specific areas of mechatronics technology.Except for afew areas ,the technology necessary to accomplish the development ofthe next generation of systems embodying the principles of mechatronics is fully within the technological reach of the Japanede .Comparisons were made in three categories :basic research ,asvanced development, and productimplementation.Except for machine vision and software ,Japanese basic research was comparable to the United States,with the Japanese closing in fase on macchine vision system technology.Japanese artificial intelligence research is falling behind ,primarily because the Japanese donot consider it an essential ingredient of their future systems ,they appear capable of closing even that gap,if required .In the advanced development and product implementation areas,Japanis equal to or better than the United States,and is continuing to pull ahead at this time .The Department of Commerce report concleuded that Japan is maintaining itsposition and isin some cases gaining ground over the United States in the application of mechatronics .Theirprogress in mechatrinics is important because it addresses the very means for next generationof data -driven advanced design and manufacturing technology. In fact ,the Department of Commerce repert cincludes that this has created a regenrative effect on Japan's manufacturing industries.TO clese the gap ,we will need to go much further than creating new tools .If we acceptthe fact that mechanical systems optimally coupled with eletronics components will be the waveof the future ,then we must also understand that the pipple effect will be felt all the way backto the university,where we now keep the two disciplines of mechanics and eletronics separated andallow them to meet only in occasional overview sessions .New curricula must be create fir a newhybrid engineer a mechatronics engineer .Only then can we be assured that future generations of product designers and manufactuiing engineers will full seek excellence in these new techniques.We need to rethink our present day approach of separating our engineering staffs both andfrom each other and from the producting engineers .Living together and communicating individualknowledge will be the key to optimum designs and new product development .The definition of mechatronics is much more significant than its combined words imply .It can physically turn engineering and manufacturing upside down. It will change the way we design and produce the next generating of high technology products.The nation that fully implements the rediments of mechatronics and vigorousely pursues it will lead the word to a new generation of technology innovation with all its profound implications.2.Benefits Of MechatronicsMechatronics may sound like utopia to many product and manufacturing managers it is often presented as the solution to nearly all of the problems in manufacturing . In particular ,it promises to increase productivity in the factory dramatically.Design changes are easy with extensive use of mechatronic elements such as CAD; CAP and MIS systems help in scheduling ; and flexible manufacturing systems ,computer-aided design ,and computer –integrated manufacturing equipment cut turnaround time for manufacturing .These subsystems minimize production costs and greatlu increase equipment utilization .Connections from CAE,CAD, and CAM help create designs that are economical to manufacture ;cintrol and communications are improved,with minimal paper flow; and CAM equipment minimizes time loss due to setup and materials handling.Many companies that make extensive use of computers view their factories as examples of mechateonic concepes, but on close wxamination their integration is horizontal-in the manufacturing area only –or at best includes primarily manufacturing and managemengt .General Electric ,as part of its effort to become a major bendor of factory automation systems ,including its Erie Locomotive Plant, its Scjenectady Steam Turbine Plant, and its Charlottesville Controls Manufacturing Division. The primary benefits of mechatronics, with an emphasis on advanced manufacturing technology and factory automation ,are summarized below.High Capitial Equipment Utilization Typically , the throughput for a set of machines in a mechatronics system will be up to three times that for the same machines in a stand-alone job shop environment . The mechatronic system achieves high efficiency by having the computer schedule every part to a machine as soon as it is free , simultaneously moving the part on the automated material handling system and downloading the appropriate computer program to the machine . In addition , the part arrives at a machine already fixtured on a pallet (this is done at a separate work station )so that the machine does not have to wait while the part is set up .Reduced Capital Equipment CostsThe high utilization of eqipment results in the need for fewer machines in the mechatronic system to do the same work load as in a conventional systenm . Reductions of 3:1 are common when replaceing machining centers in a job-shop situation with a mechatronic system. Reduced Direct Labor Costs Since each machine is completely under computer control ,full-time oversight is not repaired . Direct labor can be reduced to the less skilled personnel who fixture and defixture the parts at the work station ,and a machinist to oversee or repair the work stations ,plus the system supervisor . While the fixturing personnel in mechatronic environments require less advanced skills than corresponding workers in conventional factories , labor cost reduction is somewhat offset by the need for computing and other skills which may not be required in traditional workplaces.Reduced Work-in –Process Inventory and Lead TimeThe reduction of work –in-process in a mechatronic system is quite dramatic when compared to a job-shop environment . Reductions of 80 percent have been reported at some installations and may be attributed to a variety of factors which reduce the time a part waits for metal-cutting operations. These factors include concentration of all the equipment required to produce part into a small area ;reduction in the number of fixtures required ;reduction in the number of machines a part must travel through because processes are combined in work cells ; and efficient computer scheduling of parts batched into and within the mechatronic system.Responsiveness to Changing Production RequirementsA mechatronicsystem has the inherent flexibility to manufacture different products as the demands of the demands of the marketplace change or as engineering design changes are introduced .Furthermore , required spare part production can be mixed into regular runs without significantly disrupting the normal mechatronic system production activities.Abulity to Maintain ProdutionMany mechatronic system are designed to degrade gracefully when one or more machines fail . This is accomplished by incorporating redundant machining capability and a material handling system that allows failed machines to be bypassed . Thus , throughput is maintained at a reduced rate.High Product QualityA sometimes-overlooked advantage of a mechatronic system , especially when compare to machines that have not been federated into a cooperative system , is improve product quality . The basic integration of product design characteristics with production capability ,the high level of automation , the reduction in the munber of fixtures , and greater attention to part/machine alignment all result in a good individual part quality and excellent consistency from one workpiece to another ,further resulting in greatly reduced costs of rework.Operational Flexibility Operational flexibility offers a significant increment of enhanced productivity . In some facilities , mechateonic system can run virtually unattended during the second and the third shifts . This nearly “unmanned “ mode of operation is currently the exception rather than the rule . It should , however, become increasingly common as better sensors and computer controls are developed to detect and handle unanticipated problems such as tool breakages and part-flow jams . In this operational mode , inspection ,fixturing , and maintenance can be performed during the first shift .Capacity Flexibility With correct planning for available floor space , a mechatronics system can be designed for low production volumes initially ;as demand increase , new machines can be added easily to provide the extra capacity required.Mechatronic System ElementsThis chapter provides a brief introduction to the mechatronic system concept and the system elements required to implement mechatronic technology . The stress is on factory automation ,whiche will serve as the foundation for mechatronic technology integration in office automation and home automation .System Concept Mechatronic production systems include all aspects of product design , manufacturing , and plant management , in a coordinated data-driven computer-as-sisted system .But unlike any other process before , they will also include the operationts that are the involed in defining the product a plant is to manufacture .It is precisely here that the Japanese have excelled ,making many American firms take notice and wonder why their share of the market is disappearing.A close inspection of the process would receal that the Japanese had created new products that were so much attuned to the using public that our statle products lacked luster in the market-place . They created a need for their products and did so by that age-old principle which states, “give the customer what he wants ,not what you think he wants .”Sharing the design process with customer is an interesting process that , when considered as part of the mechatronic philosophy , becomes the prime mover for everything else that happens in factory automation.There are three general groups of mechatronic functions , as shown in Figure 2: market needs analysis ,which results in user-oriented product design ; manufacture(both fabrication and assembly ) of products on the factory floor; and enlightened management of factory operations . The three general groups noted above ,stressing the need for inproved design , product manufacturing ,and enlightened management ,are not necessarily mutually exclusive . In fact , the goal of introducing mechatronics into these systems is to break down the barriers between them so that design and manufacturing system are inextricably linded . Howerer , the three categories are useful to frame the discussion , particularly since they correspond to the organization of a typical manufacturing firm.

。最直接的機(jī)電一體化改革體現(xiàn)在自動(dòng)化工業(yè)。我們進(jìn)入了一個(gè)嶄新的時(shí)代，一輛汽車是只有幾個(gè)電子元件就能控制的機(jī)器。首先是起動(dòng)器馬達(dá)，接著出現(xiàn)的是發(fā)電機(jī)。每一次都使產(chǎn)品有了新的進(jìn)步，之后半導(dǎo)體電子元件（由集成塊、晶體管和二極管組成）的出現(xiàn)成為機(jī)械行業(yè)的奇跡。現(xiàn)今的機(jī)器是由微處理器控制，由機(jī)器人生產(chǎn)，故障分析由與外接口連接器連接的電腦控制，自動(dòng)化機(jī)器引擎。電子技術(shù)已再三的改善了機(jī)械系統(tǒng)的性能。這是機(jī)電一體化的精華─機(jī)械技術(shù)和電子技術(shù)預(yù)先計(jì)劃應(yīng)用和有效結(jié)合以創(chuàng)造一種最佳的產(chǎn)品。美國貿(mào)易部最近的一篇題為“日本技術(shù)規(guī)則委員會(huì)關(guān)于機(jī)電一體化評(píng)論”的報(bào)告比較了美國和日本在機(jī)電一體化技術(shù)上的研究和發(fā)展。除了少數(shù)領(lǐng)域外，完成使機(jī)電一體化的原理具體化的下一代系統(tǒng)的研制所必須的技術(shù)完全在日本人所能及的范圍內(nèi)。在下列三個(gè)方面作了比較：基礎(chǔ)研究、試樣樣品和產(chǎn)品實(shí)現(xiàn)三個(gè)方面。除了機(jī)械視覺系統(tǒng)和軟件系統(tǒng)外，日本的基礎(chǔ)研究與美國的是可以相比的，日本人在機(jī)器視覺系統(tǒng)（系統(tǒng)通過傳感、物體識(shí)別、圖象分析和解釋來確定物體的方位和形狀的能力，稱為機(jī)械視覺系統(tǒng)）日本人工智能方面的研究比美國相對(duì)落后，主要是日本人不認(rèn)為人工智能是與他們將來系統(tǒng)結(jié)合的關(guān)鍵。如果需要的話，他們甚至關(guān)閉且不研究人工智能。在試樣試品和產(chǎn)品實(shí)現(xiàn)方面，日本與美國持平，甚至超過美國，并在一段時(shí)間內(nèi)仍保持領(lǐng)先勢頭。美國貿(mào)易部的報(bào)告總結(jié)出：日本仍然保持其地位，在一些情況下，對(duì)于機(jī)電一體化的應(yīng)用仍勝于美國。他們?cè)跈C(jī)電一體化方面的進(jìn)步是非常重要的，因?yàn)樗窍乱淮詳?shù)據(jù)為主導(dǎo)的設(shè)計(jì)及制造技術(shù)的重要手段。實(shí)際上，美國貿(mào)易部報(bào)告的結(jié)論會(huì)對(duì)日本的工業(yè)生產(chǎn)產(chǎn)生更深遠(yuǎn)的影響。為了縮小差距，我們不僅要制造新的工具，而且我們要走的路更遠(yuǎn)。如果我們接受電子元件最佳結(jié)合的機(jī)械系統(tǒng)將是未來的浪潮。這一事實(shí)，那么我們一定能理解。這波紋效應(yīng)一直到大學(xué)都能感覺到。在大學(xué)里我們把機(jī)械學(xué)和電子學(xué)這兩門學(xué)科分離，而且僅在偶然的綜合性課程中允許二者相遇?，F(xiàn)在的課程必須能夠創(chuàng)造新的混合型的工程師──機(jī)電一體化工程師。只有這樣，我們才能保證將來下一代的產(chǎn)品設(shè)計(jì)者和制造工程師將在新的技術(shù)領(lǐng)域有出色的表現(xiàn)。我們必須需要重新思考一下我們現(xiàn)代的劃分我們機(jī)電一體化工程師成員的方法，既要彼此互相區(qū)別，而又要與產(chǎn)品工程師相互區(qū)別。居住在一起，個(gè)人之間相互交流在產(chǎn)品將產(chǎn)生一種復(fù)雜的效應(yīng)。最大化的相互作用是優(yōu)化設(shè)計(jì)和新產(chǎn)品開發(fā)的關(guān)鍵。機(jī)電一體化的定義的重要性不在于它是詞語的簡單組合，他把工程技術(shù)和制造技術(shù)相互結(jié)合，他會(huì)改變我們?cè)O(shè)計(jì)和生產(chǎn)下一代高科技產(chǎn)品的方式，充分為機(jī)電一體化提供基礎(chǔ)，并強(qiáng)有利的推行機(jī)電一體化的國家將把世界導(dǎo)向一場具有深遠(yuǎn)意義的新一代技術(shù)革命。2：機(jī)電一體化的優(yōu)勢機(jī)電一體化對(duì)于許多產(chǎn)品和制造者聽起來似乎是近乎理想的完美境界，因?yàn)闄C(jī)電一體化幾乎能解決生產(chǎn)制造中的所有問題，更特別的是，他很有可能顯著的提高工廠產(chǎn)品的產(chǎn)量。廣泛的利用機(jī)電一體化組成部分例如

80%，這些都?xì)w功于減少了定貨到交貨的時(shí)間的諸多因素，這些因素包括：全部生產(chǎn)零件所需的設(shè)備都集中在一個(gè)小的區(qū)域內(nèi)；所需夾具的數(shù)量的減少；由于加工工藝被組合在工作單元中而引起的零件所必須通過的機(jī)器的數(shù)量的減少；以及分批進(jìn)入的和已在機(jī)電一體化系統(tǒng)中的零件要進(jìn)行有效的計(jì)算機(jī)調(diào)度。對(duì)改變的產(chǎn)品的需求快速響應(yīng)機(jī)電一體化系統(tǒng)對(duì)于不同產(chǎn)品的生產(chǎn)需求和市場需求改變或者工程設(shè)計(jì)改變都有固有的靈活性。更進(jìn)一步，備用件的需求不會(huì)大大擾亂正常的機(jī)電一體化系統(tǒng)的生產(chǎn)活動(dòng)。生產(chǎn)的可維護(hù)性許多機(jī)電一體化系統(tǒng)能夠適度的降低當(dāng)一個(gè)或更多的機(jī)器失效后不能正常工作的機(jī)率。當(dāng)某臺(tái)機(jī)器失效后多余的機(jī)器和原材料控制系統(tǒng)使系統(tǒng)繞過失效的機(jī)器，因此，生產(chǎn)量始終保持在一個(gè)恒定的百分率上。高的產(chǎn)品質(zhì)量經(jīng)常性的監(jiān)督機(jī)電一體化系統(tǒng)，特別是當(dāng)與沒有與合作系統(tǒng)聯(lián)合的機(jī)器系統(tǒng)相比能夠更能提高產(chǎn)品的質(zhì)量，產(chǎn)品設(shè)計(jì)性能與生產(chǎn)能力的基本結(jié)合，高水平的自動(dòng)化夾具數(shù)量和駐留的機(jī)器數(shù)量的減少，設(shè)計(jì)的更好的永久性夾具，更加注意零件與機(jī)器的調(diào)整，所有這些都使單個(gè)零件質(zhì)量良好，零件之間有極好的一致性，并且導(dǎo)致返工成本的大大減少。靈活的控制靈活的控制能夠顯著的增加產(chǎn)品的產(chǎn)量，在一些設(shè)施里，機(jī)電一體化系統(tǒng)可以在中班和晚班和無人看管條件下自動(dòng)運(yùn)行，這種幾乎無人的操作方式目前是例外的情況，而不是常規(guī)，但是他可以變成常規(guī)。如果好的傳感器和計(jì)算機(jī)能夠控制和解決一些非預(yù)期的情況，例如刀具劃傷、零件流動(dòng)阻滯等等。在這種操作模式下，監(jiān)察、安裝和維修可以在第一班即可完成。靈活性由于正確的操作可利用的占地面積的計(jì)劃，一個(gè)機(jī)電一體化系統(tǒng)最初可為低產(chǎn)量而設(shè)計(jì)。隨著需求的增長，可以容易的增添新機(jī)器，以提供需要的附加生產(chǎn)能力。3: 機(jī)電一體化的組成這一章節(jié)簡要的介紹機(jī)電一體化系統(tǒng)的原理，而且講述了需要機(jī)電一體化各個(gè)組成部分來實(shí)現(xiàn)機(jī)電一體化工藝技術(shù)。 機(jī)電一體化系統(tǒng)的 重點(diǎn)應(yīng)放在

恰好是日本人以勝人一籌之處，使得許多美國公司注意并想知道為什么它們（占有）的市場份額正在消失。一份關(guān)于這種工藝的周密調(diào)查講揭示：日本人已創(chuàng)造了非常適合于用戶的新產(chǎn)品，以至我們的陳舊產(chǎn)品在市場上失去了光澤。他們引起了對(duì)他們產(chǎn)品的需要，并且是按照那個(gè)古老的原則做到這一點(diǎn)的，這個(gè)原則是：“給予顧客它所向要的東西，而不是給他認(rèn)為他鄉(xiāng)要的東西。與顧客分擔(dān)設(shè)計(jì)過程是一種有趣的過程，當(dāng)把她作為機(jī)電一體化基本原理的一部分考慮時(shí)，這一過程為在工廠自動(dòng)化方面發(fā)生的其他一切事實(shí)的動(dòng)力。，機(jī)電一體化功能一般分為三類：與用戶相關(guān)的產(chǎn)品設(shè)計(jì)的市場分析，在工廠現(xiàn)場的產(chǎn)品的生產(chǎn)制造，開明的工廠經(jīng)營管理。上述三大類功能，既強(qiáng)調(diào)需要改進(jìn)的設(shè)計(jì)，產(chǎn)品的制造，開明的管理，不是必然相互排斥的。實(shí)際上，把機(jī)電一體化引入到這些系統(tǒng)的目的掃除它們之間的壁壘，從而使設(shè)計(jì)和制造系統(tǒng)能夠自然而然的連接起來，然而這三種功能構(gòu)成討論是很有好處的，特別，當(dāng)他們與典型的制造公司對(duì)應(yīng)更能體現(xiàn)其好處。
