第一篇：機(jī)械工程專業(yè)英語課翻譯

Unit1 Two methods of designating limit dimensions are considered as standard.One method is the maximum material method in which the large dimension is placed above the smaller dimension for male parts, and the reverse is true for female parts.This method is well suited for small lot quantities because it is likely that the machinist himself may check the dimension of the parts.In so doing he will be verifying initially the large dimension of the male parts and the smaller dimension of the female part.other method is the maximum number method and is preferred by production and quality control departments.In this method of designating a dimension , the large number is always placed above the smaller number ,regardless of whether the part is male or female.兩種方法都被看作是指定極限尺寸標(biāo)準(zhǔn)。一種方法是最大的資料法,大尺寸較小的尺寸擺在上面男性部件,事實(shí)正相反對(duì)女性的部分。這種方法很適合小批量的數(shù)量,因?yàn)樗强赡艿?自己可能檢查機(jī)械師維度的零件。

這樣做的話,他就會(huì)驗(yàn)證最初的男大尺寸零件和小尺寸的女性的部分。另一個(gè)方法是最大的數(shù)字方法和優(yōu)先生產(chǎn)和質(zhì)量控制部門。在該方法中,指定了一個(gè)維度,大量總是擺在上面較小的號(hào)碼,不管部分男”或“女”。Unit3(1)From its inception ,quantum mechanics had two apparently different mathematical forms: the wave mechanics of E.Sehrodinger ,which emphasizes the spatial probability distributions in the quantum states ,and the matrix mechanics of W.Heisenberg, which emphasizes the transitions between states.成立以來,量子力學(xué)有兩個(gè)明顯不同的數(shù)學(xué)形態(tài)E.Sehrodinger波動(dòng)力學(xué)的,它強(qiáng)調(diào)在空間概率分布的量子狀態(tài)時(shí),矩陣力學(xué)的W.Heisenberg,他們

(2)the rigid-body assumption cannot be used when internal stresses and strains due to the applied forces are to be analyzed.Thus we consider the body to be capable of deforming.such analysis is frequently called elastic-body analysis, using the additional assumption that the body remains elastic within the range of the applied force.在剛體假設(shè)時(shí)不能用內(nèi)部的緊張和壓力是由于受力進(jìn)行分析。因此我們認(rèn)為身體能變形。這樣的分析常被稱為elastic-body分析,利用附加假設(shè)物體保持彈性范圍內(nèi)應(yīng)用的力量。Unit4 The relation velocity or velocity polygon method of performing a velocity analysis of a mechanism is one of several methods available.The pole represents all points on the mechanism having zero velocity.Lines drawn from the pole to point on the velocity polygon represent the absolute velocities of the corresponding point on the mechanism.A line connecting any two point on the velocity polygon represents the relative velocity for the two corresponding points on the mechanism.速度或速度的關(guān)系,執(zhí)行一個(gè)多邊形方法速度分析機(jī)制已有方法是其中之一。桿位代表所有的點(diǎn)在零速度機(jī)制。線來自桿來點(diǎn)在多邊形代表了速度絕對(duì)速度點(diǎn)所對(duì)應(yīng)的機(jī)制。一條線連接任何兩個(gè)點(diǎn)在多邊形的相對(duì)速度速度是兩個(gè)對(duì)應(yīng)點(diǎn)的運(yùn)行機(jī)制。UNIT5 The body to be guided usually is a part of a floating link, of which not only is the path of a point p prescribed, but also the rotation of a line passing through the point and embedded in the body.For instance, the line might represent a carrier link in an automatic machinery where a point located on the carrier link has a prescribed path while the carrier has a prescribed angular orientation.Prescribing the movement of the bucket for a bucket loader is another example of motion generation mechanisms.The path of tip of the bucket is critical since the tip must perform a scooping trajectory followed by a lifting and a dumping trajectory.The angular orientation of the bucket is equally important to ensure that the load is dumping form the correct position.身體被引導(dǎo)通常是一個(gè)浮動(dòng)的一部分環(huán)節(jié),不僅是一個(gè)p點(diǎn)的路徑的處方,但也轉(zhuǎn)動(dòng)而產(chǎn)生的點(diǎn)和線通過植入人體內(nèi)。例如,也許表示一個(gè)載體線自動(dòng)機(jī)械連接在一個(gè)點(diǎn)位于承運(yùn)人規(guī)定的路徑而連結(jié)承運(yùn)人已規(guī)定的角方向。處方的運(yùn)動(dòng)為一桶桶裝載機(jī)的另一個(gè)例子是運(yùn)動(dòng)產(chǎn)生機(jī)理。路徑的頂端的臨界自桶提示必須執(zhí)行作業(yè)軌跡跟隨一個(gè)提升和反傾銷的軌道。吊桶角定向同樣重要的是確保載荷傾銷形成正確的位置。UNIT6 The competent engineer should not be afraid of the possibility of not succeeding in a presentation.In fact ,occasional failure should be expected because failure or criticism seems to accompany every really creative idea.There is a great deal to be learned from a failure , and the greatest gains are obtained by those willing to risk defeat.In the final analysis , the real failure would lie deciding not to make the presentation at all.主管工程師不應(yīng)該害怕沒有成功的可能在一個(gè)表現(xiàn)。事實(shí)上,偶爾失敗應(yīng)該會(huì)因?yàn)槭』蚺u(píng)似乎伴隨每一個(gè)真正具有創(chuàng)造性的想法。有許多讓你從中得到教訓(xùn)是失敗的,并得到了最大的收獲是那些愿意冒險(xiǎn)失敗。在最后的分析中,真正的失敗會(huì)撒謊決定不做演講。UNIT7 Kinematic synthesis, on the other hand ,is the process of designing a mechanism to accomplish a desired task.Here,both choosing the type as well as the dimensions of the new mechanism is designed the way it is, and the ability to visualize relative motion ,to reason why a mechanism is designed the way it is, and the ability to improve on a particular design are marks of a successful kinematician.Although some of this ability cones in the form of innate creativity, much of it is a learned skill that improves with practice..運(yùn)動(dòng)合成,另一方面,是一個(gè)過程,設(shè)計(jì)一個(gè)機(jī)制來實(shí)現(xiàn)所需的任務(wù)。在這里,兩個(gè)選擇類型以及尺寸的新的機(jī)制設(shè)計(jì)的方式,能夠看清相對(duì)運(yùn)動(dòng),為什么一個(gè)機(jī)制設(shè)計(jì)就是這樣,并且能夠提高在某一個(gè)特定設(shè)計(jì)的一個(gè)成功的kinematician標(biāo)志。雖然一些這樣的能力錐的形式,天生的創(chuàng)造力,很多都是門學(xué)問,改善與實(shí)踐相結(jié)合。UNIT8 The angle between the line of action perpendicular to the centerline of the two gears in meshing.Pressure Angles for spur gears are usually 14.5 or 20 degrees, although other values can be used.Meshing gears must have the same pressure angles.In the case of a rack, the teeth have the straight sides inclined at angle corresponding to the pressure angle.2)Spur gear will be considered first for several reasons.In the first place, they are the simplest and the least expensive of gears and they may be used to transmit power between parallel shafts, also, spur gears definitions are usually applicable to other types.角度的行動(dòng)路線之間的垂直中心線的兩檔在嚙合。壓力角直齒圓柱齒輪通常為14.5或20度,盡管其他價(jià)值都可以使用。嚙合齒輪必須具有相同的壓力角。在案件的一個(gè)架子上,牙齒有直邊角度斜在相應(yīng)的壓力角。

2)齒輪將首先被考慮幾個(gè)原因。首先,他們是最簡單、最便宜的齒輪和他們的可用于傳輸功率的平行軸之間,同時(shí),直齒圓柱齒輪的定義通常適用于其他類型。UNIT9 Journal bearing materials should preferably have the following characteristics: good compressive and fatigue strength;good heat conductivity;chemical inertness to shaft and housing materials , as well as lubricants;ductility , to conform to the shape of housing and journal , and to permit the embedment of foreign which would otherwise scour the shaft;reasonable price.軸承材料中應(yīng)當(dāng)有以下特點(diǎn):良好的壓應(yīng)力和疲勞強(qiáng)度,良好的導(dǎo)熱性、化學(xué)惰性軸和建筑材料,以及潤滑劑,延性、符合形狀的住房和雜志,并且允許外國,否則我們就會(huì)埋沖刷軸,價(jià)格合理。

Unit10 Conventional centrifugal pumps often have double-shrouded impellers to guide the flow and support the vanes.And the vanes and impeller casing are shaped to partially convert the velocity energy into static pressure by diffusion with in the casing.this improves efficiency somewhat， but the static pressure by diffusion inside the casing forces leakage flow back to suction;therefore “wearing” rings are necessary for sealing between the impeller and casing near the hub.傳統(tǒng)的離心泵葉輪經(jīng)常有double-shrouded指導(dǎo)和支持葉片流動(dòng)。和葉片形狀、葉輪套管部分轉(zhuǎn)換速度能量進(jìn)入靜壓通過擴(kuò)散與套管。這提高了行政效率有點(diǎn),但靜壓力內(nèi)部力量通過擴(kuò)散套管泄漏流回抽吸,所以“穿著“環(huán)之間是必要的,為密封葉輪和泵體附近的中心。UNIT11 When a constant-displacement pump is used and when it delivers a fixed volume of fluid to the circuit, feed control must be accomplished with metering valves.Pressure-compensated variable-displacement pimps may also with flow-control valves to ensure repetitive flows in an economical pattern.When the load is reasonably constant.the metering valve can be a fixed or adjustable orifice.Such an orifice will maintain metering valves are used.The pressure compensator maintains a constant pressure drop across the orifice regardless of load.當(dāng)一個(gè)constant-displacement泵使用和當(dāng)它提供了一個(gè)固定量的流體,電路、飼料控制必須做到與儀表閥門。Pressure-compensated皮條客也可能與流量控制變量,以確保重復(fù)的流閥在一個(gè)經(jīng)濟(jì)的模式。當(dāng)載荷相當(dāng)穩(wěn)定。計(jì)量閥可以固定或可調(diào)節(jié)孔。這樣將會(huì)保持限流閥孔口使用。保持恒定的壓力補(bǔ)償器壓力降穿過孔無論負(fù)荷。UNIT12 Although plain carbon steels work well for many uses and are the cheapest steels and therefore the most used, they can’t completely fulfill the requirements for some work.Individual or groups of properties can be improved by addition of various elements in the form of alloys.Even plain carbon steels are alloys of at least iron, carbon, and manganese, but the term alloy steel refers to steels containing elements other than these in controlled quantities greater than impurity concentration or, in the case of manganese, greater than 1.5%.雖然碳素鋼好工作的許多用途,是最便宜的鋼材,因此最常用的,它們不可能完全滿足以上要求一些工作。個(gè)人或群體的特性,可改善添加各種形式的合金元素。即使碳素鋼至少是合金鐵、碳、錳,但是術(shù)語是指鋼合金鋼包含其它元素的數(shù)量比這比雜質(zhì)濃度控制,或者在案件的錳、大于1.5%。UNIT13: 1)Forging means the shaping of metal by a series of hammer blows,or by slow application of pressure.The simplest example is a blacksmith’s forging of a hot piece of metal by hamming the workpiece on an anvil.2)Heavy smith’s forging is fundamentally similar,differing only in the scale of the operation.The workpiece may be an ingot of 100 tons and the deforming force provided by a massive forging hammer,but the whole process is controlled by the master smith,who decedes each time where,and with what force,the blow should take place.3)Forging operations may be carried out using either forging hammers or forging presser With a press,asopposed to a hammer,pressure is slowly applied and plastic deformation tends to occur fairly uniformly throughout the material.4)Forging hammers are of two basic types with the large hammer either dropping on to the workpiece accelerated by gravity alone or,as in the steam hammer,accelerated by both gravity and steam pressure.5)Smith’s or open-die forging is used for making very large forgings or when the number of forgings of a particular design is small.Open-die forging is also used to perform metal prior to find shaping by means of closed-die forging.6)Closed-die forging involves the use of accurately machined die blocks,The capital cost of a pair of die blocks is high, but this is allowable when it is required to make forgings to close dimensional tolerances and in large quality,as would be the case for,say,connecting rods for the engine of a popular car.7)Casting,then,is the process by which molten metal is transformed in one step into a part or component.The part or component produced is called a casting.8)Most cast iron is melted in a cupola.It will melt at a proper temperatue and will be fluid when it is molten 1)形成的金屬鍛造方法通過一系列的打擊,或慢應(yīng)用的壓力。最簡單的例子是鐵匠的鍛造中的一個(gè)熱點(diǎn)塊金屬工件的鐵砧上理論值。

2)重史密斯的鍛造基本上是相似,不同的只在大規(guī)模的操作?？赡苁且粋€(gè)鋼錠工件的變形力100噸,由一個(gè)巨大的鍛錘,但整個(gè)過程控制,由主人史密斯,他decedes每次在哪里,用什么力量,打擊應(yīng)該采取的地方。

3)可以實(shí)行鍛造操作使用的是鍛造錘或鍛造壓與出版社,asopposed到一把錘子,壓力是慢慢地應(yīng)用和塑性變形常發(fā)生在相當(dāng)均勻的物質(zhì)。

4)鍛造錘子的兩種基本形式也有大型錘落在工件的加速重力單獨(dú)或,如在蒸汽錘加速了兩個(gè)重力和蒸汽壓力。

5)史密斯的或開式模鍛是用來生產(chǎn)非常大鍛件鍛造的數(shù)量或當(dāng)某一特定的設(shè)計(jì)是小的。開式模鍛金屬也被用來執(zhí)行之前找到通過傘齒輪完全閉塞式鍛造成形。

6)傘齒輪完全閉塞式鍛造涉及到使用經(jīng)過精密機(jī)加工模具街區(qū),資本成本一副死塊很高,但這是有必要的時(shí)候允許使鍛件尺寸公差關(guān)閉。在大的素質(zhì),同時(shí)會(huì)這樣說,連桿為發(fā)動(dòng)機(jī)一個(gè)受歡迎的汽車。

7)鑄造,那麼,這個(gè)過程是一個(gè)轉(zhuǎn)型的熔融金屬步入一個(gè)部分或組件。生產(chǎn)部件或組件被稱為鑄件。

8)最鑄鐵在沖天爐熔化。它將會(huì)融化在適當(dāng)?shù)膖emperatue流體時(shí),將是熔化的 UNIT14 Minimum hardness and maximum ductility of steel can be produced by a process called spheroidizing, which causes the iron carbide to form in small spheres or nodules in a ferrite matrix.In order to start with small grains that spheroidize more readily, the process is usually perforated on normalized steel.Several variations of processing are used, but all require the holding of the near the A1 temperature(usually slightly below)for a number of hours to allow the iron carbide to form on its more stable and lower energy state of small, rounded globules.The main need for the process is to improve the machinability quality of high carbon steel and to pretreat hardened steel to help produce greater structural uniformity after quenching.Because of the lengthy treatment time and therefore rather high cost, spheroidizing is not performed nearly as much as annealing or normalizing.硬度最小和最大延性鋼可以由一個(gè)過程稱為球化,使鐵碳化物的形成,在小球體在鐵素體基體中。為了開始小顆粒更容易,起到球,這個(gè)過程通常穿孔在規(guī)范化鋼。好幾個(gè)不同的處理都用得上,但是都需要的把持A1附近的溫度(通常略低于)的小時(shí)數(shù)允許鐵碳化物形成對(duì)其更加穩(wěn)定和較低的能量狀態(tài)的小,圓形的小滴。

16單元

1)The main factors in chip formaition are: the tool(material and geometry), the work material(material, geometry, and rigidity), and the cutting conditions.2)Discontinuous chips can also be produced under certain conditions with more ductile materials such as steel, causing a rough surface.3)Continuous and long chips may be difficult to handle and, consequently, the tool must be provided with a chip breaker, which curls and breaks the chip into short length.4)This is because the actual shear strain at fracture in the material in the direction of the shear plane, so that the material is removed in fairly small segments.1)在芯片formaition的主要因素是:工具(材料和幾何),工作資料(材料、幾何、和剛度),和切削條件。2)不連續(xù)的芯片生產(chǎn)還可以在一定條件下,有更多的韌性材料,如鋼鐵,使粗糙的表面。3)連續(xù)長芯片可能很難處理,因此,工具必須提供一個(gè)芯片斷路器,該河并打破芯片短長度。4)這是由于實(shí)際剪切應(yīng)變斷裂資料的方向剪切平面,以便材料移到相當(dāng)小的部分。

計(jì)算機(jī)輔助設(shè)計(jì)與制造

Computer-aided design（CAD）involves the use of computers to create design drawings and product models.Computer-aided design is usually associated with interactive computer graphics（known as a CAD system）.Computer-aided design systems are powerful tools and are used in the mechanical design and geometric modeling of products and components.計(jì)算機(jī)輔助設(shè)計(jì)（CAD）是指用計(jì)算機(jī)來創(chuàng)造設(shè)計(jì)圖紙和產(chǎn)品模型。計(jì)算機(jī)輔助設(shè)計(jì)通常是與交互式計(jì)算機(jī)圖形學(xué)（稱為CAD系統(tǒng)）有關(guān)系的。計(jì)算機(jī)輔助設(shè)計(jì)系統(tǒng)是功能強(qiáng)大的工具，被用于在機(jī)械設(shè)計(jì)以及產(chǎn)品和零件的幾何建模。

In CAD，the drawing board is replaced by electronic input and output devices.When using a CAD system，the designer can conceptualize the object to be designed more easily on the Graphics screen and can consider alternative designs or modify a particular design quickly to meet the necessary design requirements or changes.The designer can then subject the design to a variety of engineering analyses and can identify potential problems（such as an excessive load or deflection）.The speed and accuracy of such analyses far surpass what is available from traditional methods.在CAD（計(jì)算機(jī)輔助設(shè)計(jì)）中，傳統(tǒng)的畫圖板被電子輸入和輸出設(shè)備所替換。當(dāng)使用CAD系統(tǒng)時(shí)，設(shè)計(jì)者可以使對(duì)象概念化以便更容易在圖形屏幕上設(shè)計(jì)，并且可以考慮替代設(shè)計(jì)或快速地修改一個(gè)特定的設(shè)計(jì)來達(dá)到必要的設(shè)計(jì)要求或變化。因而設(shè)計(jì)者可以提供多種工程分析并且可以識(shí)別潛在的問題（如過負(fù)荷或變形）。這些分析的速度和準(zhǔn)確性都遠(yuǎn)遠(yuǎn)超過了傳統(tǒng)的方法。

Draft productivity rises dramatically.When something is drawn once，it never has to be drawn again.it can be retrieved from a library ,and can be duplicated, stretched, sized, and changed in many ways without having to be redrawn。Cut and paste techniques are used as labor-saving aids.設(shè)計(jì)生產(chǎn)率的提高是顯著的。當(dāng)某些圖形被繪制一次后，就沒必要再畫第二次。它可以從圖形庫中恢復(fù)，可以被復(fù)制，拉伸，改變大小，和其他許多方面的改變而無需重新繪制。剪切和粘貼技巧作為節(jié)省勞力的助手被使用。

CAD makes possible multiview 2D drawings，and the drawings can be reproduced in different levels of reduction and enlargement.It gives the mechanical engineer the ability to magnify even the smallest of components to ascertain if assembled components fit properly.Parts with different characteristics，such as movable or stationary，can be assigned different colors on the display.CAD使二維圖紙多重視圖變?yōu)榭赡?，并且圖形可以在大小不同的圖層里重生。它使機(jī)械工程師有能力放大甚至最小的部件來確定構(gòu)件是否裝配合適。對(duì)于具有不同特性的零部件，如移動(dòng)或靜止，可以指定不同的顏色在顯示屏上標(biāo)示。

have even more freedom with the advent of 3-D parts and manipulate them in endless variations to achieve the desired results.Through finite element analysis，stresses can be applied to be a computer model and the results graphically displayed，giving the designer quick feedback on any inherent problems in a design before the creation of a physical prototype.隨著三維建模的出現(xiàn)設(shè)計(jì)師有了更多自由和無限制的修改它們以實(shí)現(xiàn)所期望的結(jié)果。通過有限元分析，應(yīng)力加到計(jì)算機(jī)模型上并且以圖形化的方式顯示其結(jié)果，在產(chǎn)品物理原型生產(chǎn)之前，對(duì)設(shè)計(jì)中的任何內(nèi)在問題給設(shè)計(jì)者一個(gè)快速的反饋。Designers In addition to the design’s geometric and dimensional features，other information（such as a list of materials，specification，and manufacturing instructions）is stored in the CAD database.Using such information ,the designer can then analyze the economics of alternative designs.除了設(shè)計(jì)的幾何和尺寸特性之外，其他信息(比如材料清單、規(guī)格、和制造說明)都存儲(chǔ)在CAD數(shù)據(jù)庫里。利用這些信息，設(shè)計(jì)師可以分析備選設(shè)計(jì)的經(jīng)濟(jì)性。Computer-aided manufacturing(CAM)involves the uses of computers and computer technology to assist in all the phases of manufacturing a product，including process and production planning，machining，scheduling，management，and quality control.Computer-aided design and computer-aided manufacturing are often combined into CAD/CAM systems.計(jì)算機(jī)輔助制造(CAM)包括使用計(jì)算機(jī)和計(jì)算機(jī)技術(shù)來協(xié)助制造產(chǎn)品的所有階段，包括工藝和生產(chǎn)計(jì)劃，加工，調(diào)度，管理，和質(zhì)量控制。計(jì)算機(jī)輔助設(shè)計(jì)和計(jì)算機(jī)輔助制造常常是和CAD / CAM系統(tǒng)相結(jié)合的。

This combination allow the transfer of information from the design stage into the stage of

planning for the manufacture of a product，without the need to reenter the data on part geometry manually.The database developed during CAD is stored； then it is processed further，by CAM，into the necessary data and instructions for operating and controlling production machinery，material-handling equipment，and automated testing and inspection for product quality.這種組合允許一個(gè)產(chǎn)品的信息從設(shè)計(jì)階段傳遞到加工規(guī)劃階段，而不需要手動(dòng)重新輸入幾何部件的數(shù)據(jù)。計(jì)算機(jī)輔助設(shè)計(jì)研發(fā)期間存儲(chǔ)在數(shù)據(jù)庫，然后通過計(jì)算機(jī)輔助制造進(jìn)一步處理，一直到必要的數(shù)據(jù)和指令的操作和控制生產(chǎn)機(jī)械、物料搬運(yùn)設(shè)備，自動(dòng)化測試和檢驗(yàn)產(chǎn)品質(zhì)量。

In machining operations，an important feature of CAD/CAM is its capability to describe the tool path for various operations，such as NC turning，milling，and drilling.The instructions（programs）are computer generated，and they can be modified by the programmer to optimize the tool path.The engineer or technician can then display and visually check the tool path for possible tool collisions with fixtures or other interferences.The tool path can be modified at any time，to accommodate other part shapes to be machined.在機(jī)械加工中，CAD/CAM的一個(gè)重要特征是它有可以描述刀具運(yùn)動(dòng)軌跡的能力，如數(shù)控車削，銑削，鉆孔。指令（程序）是計(jì)算機(jī)生成的，它們可以由程序員修改優(yōu)化刀具路徑。工程師或技術(shù)員可以顯示和檢查刀具路徑可能與夾具或其他干擾工具碰撞。刀具路徑可以隨時(shí)修改，以適應(yīng)其他部分的形狀被加工。

Some typical applications of CAD/CAM are：（a）programming for NC，CNC，and industrial robots；（b）design of tools and fixtures and EDM electodes；（c）quality control and inspection，for instance，coordinate-measuring machines programmed on a CAD/CAM workstation；（d）process planning and scheduling ；and（e）plant layout.CAD / CAM的一些典型應(yīng)用是：（a）數(shù)控編程，計(jì)算機(jī)數(shù)控編程和工業(yè)機(jī)器人；（b）工具和夾具以及電火花電極的設(shè)計(jì)；（c）質(zhì)量控制和檢查，例如，在CAD / CAM工作站上的坐標(biāo)測量機(jī)編程；（d）工藝規(guī)劃與調(diào)度；和（e）工廠布局。

The emergence of CAD/CAM has had a major impact on manufacturing，by standardizing product development and by reducing design effort，tryout，and prototype work；it has made possible significantly reduced costs and improved productivity.The two-engine Boeing 777 passenger airplane，for example, was designed completed by computer（paperless design）.The plane is constructed directly from the CAD/CAM software developed（an enhanced CATIA system）and no prototypes or mockups were built，such as were required for previous models.CAD/CAM的出現(xiàn)對(duì)制造業(yè)產(chǎn)生了重大影響，通過產(chǎn)品開發(fā)的標(biāo)準(zhǔn)化和減少設(shè)計(jì)工作量，試用，和原型的工作；它有可能大大降低成本和提高生產(chǎn)力。例如雙引擎的波音777客機(jī)就是由計(jì)算機(jī)設(shè)計(jì)完成（無紙化設(shè)計(jì)）。這架飛機(jī)直接從CAD/CAM軟件開發(fā)（增強(qiáng)CATIA系統(tǒng)）并沒有建立原型或?qū)嵨锬Ｐ偷那闆r下制造出來，如以前所需要的的模型。
