機(jī)械工程英語(yǔ)口語(yǔ)是機(jī)械工程師必備的技能之一，它是在國(guó)際機(jī)械工程領(lǐng)域中進(jìn)行交流的主要工具。在機(jī)械工程領(lǐng)域，英語(yǔ)口語(yǔ)涉及到很多專業(yè)術(shù)語(yǔ)和常用語(yǔ)句，掌握這些語(yǔ)言技能對(duì)于機(jī)械工程師來(lái)說(shuō)至關(guān)重要。為大家整理了五篇常用的機(jī)械工程英語(yǔ)口語(yǔ)，歡迎閱讀！
1.常用的機(jī)械工程英語(yǔ)口語(yǔ) 篇一
CNC software is developed to augment the capabilities of a particular machine tool.CNC的提高可以提高特殊車(chē)床的能力。
the outward appearance of a CNC system is similar to that of a conventional NC machine.CNC的外部系統(tǒng)與傳統(tǒng)的NC機(jī)相似。
However, the way in which the program is used in CNC is different.然而CNC中的程序使用方法是不同的。
With a conventional NC system, the punched tape is cycled through the tape reader for each workpart in the batch. The MCU reads in a block of instructions on the tape, executing that block before proceeding to the next block.與傳統(tǒng)的數(shù)控系統(tǒng)比,紙帶通過(guò)紙帶閱讀機(jī)對(duì)每個(gè)批次的工件循環(huán)。MCU讀取磁帶上的指示塊,執(zhí)行該塊,然后進(jìn)行下一個(gè)塊。
In CNC, the entire program is entered once and stored in computer memory.在數(shù)控中,整個(gè)程序一旦進(jìn)入并儲(chǔ)存在電腦的存儲(chǔ)器中。
2.常用的機(jī)械工程英語(yǔ)口語(yǔ) 篇二
The machining cycle for each part is controlled by the program contained in memory rather than from the tape itself.每個(gè)零件的加工周期控制在內(nèi)存中,而不是來(lái)自磁帶本身的程序。
Control algorithms contained in the computer convert the part program instructions into actions of the machine tool (or other processing equipment).在計(jì)算機(jī)中的控制算法轉(zhuǎn)換成機(jī)床或其他加工設(shè)備的行動(dòng)的一部分程序指令。
Certain functions are carried out by hard-wired components in the MCU.MCU中進(jìn)行硬連接組件的某些功能。
For example, circular interpolation calculations are often performed by hardwired circuits rather than by stored program. Also, a hardware interface is required to make the connections with the machine tool servo systems.例如,圓弧插補(bǔ)計(jì)算往往是通過(guò)硬連接的電路,而不是由存儲(chǔ)程序執(zhí)行。另外,硬件接口需要與機(jī)床伺服系統(tǒng)連接。

Since the introduction of DNC, there have been dramatic advances in computer technology.由于DNC技術(shù)的介入,在計(jì)算機(jī)技術(shù)上得到了很大的發(fā)展。
The physical size and cost of a digital computer have been significantly reduced at the same time that its computational capabilities have been substantially increased.計(jì)算機(jī)在尺寸和成本顯著減少的同時(shí),計(jì)算機(jī)的能力卻有很大的提高。
In numerical control, the result of these advances has been that the large hard-wired MCU of conventional NC have been replaced by control units based on the digital computer. Initially, minicomputers were utilized in the early 1970s.在數(shù)控中,這些發(fā)展使得由硬件布置的MCU變?yōu)閿?shù)字電腦控制的控制單元。最早,小型機(jī)在1970 年使用。
As further miniaturization occurred in computers, minicomputers were replaced by today's microcomputers.隨著計(jì)算機(jī)進(jìn)一步小型化,小型機(jī)被當(dāng)今的微型機(jī)取代。
Computer numerical control is an NC system using dedicated microcomputer as the machine control unit.計(jì)算機(jī)控制也是一種數(shù)字控制,它采用微型計(jì)算機(jī)作為控制單元。
DNC computers distribute instructional data to, and collect data from, a large number of machines. CNC computers control only one machine, or a small number of machines.DNC 電腦接受和發(fā)送指令數(shù)據(jù)都是來(lái)自許多機(jī)器,CNC電腦控制只是一個(gè)機(jī)器或多個(gè)機(jī)器。
DNC computers occupy a location that is typically remote from the machines under their control. CNC computers are located very near their machine tools.DNC 電腦占有一個(gè)位置通過(guò)控制來(lái)實(shí)現(xiàn)機(jī)器的旋轉(zhuǎn)。CNC電腦要非?？拷?chē)床。
DNC software is developed not only to control individual pieces of production equipment, but also to serve as part of a management information system in the manufacturing sector of the firm.DNC 軟件的發(fā)展不經(jīng)可以控制生產(chǎn)設(shè)備的每個(gè)單獨(dú)零件,還可以在生產(chǎn)堅(jiān)固性方面提供主要控制信息。
4.常用的機(jī)械工程英語(yǔ)口語(yǔ) 篇四
The computer calls the part program instructions from bulk storage and sends them to the individual machines as the need arises.計(jì)算機(jī)從海量?jī)?nèi)存中取出部分程序指令送入到需要的獨(dú)立機(jī)床中。
It also receives data back from the machines.相應(yīng)的計(jì)算機(jī)也接受機(jī)床反饋信息。
This two-way information flow occurs in real time, which means that each machine’s requests for instructions must be satisfied almost instantaneously.這種雙工的信息流在實(shí)時(shí)控制加工系統(tǒng)中出現(xiàn)意味著每臺(tái)機(jī)床需要指令的請(qǐng)求能立即得到回應(yīng)。
Similarly, the computer must always be ready to receive information from the machines and to respond accordingly.類似的，計(jì)算機(jī)必須總是要準(zhǔn)備要接受信息和進(jìn)行回應(yīng)。
These satellites are smaller computers, and they serve to take some of the burden off the larger central computer.衛(wèi)星計(jì)算機(jī)是更小的計(jì)算機(jī) 可以分擔(dān)中央計(jì)算任務(wù) 減輕其負(fù)擔(dān)。
Each satellite controls several machines.每臺(tái)衛(wèi)星控制幾臺(tái)機(jī)床。
5.常用的機(jī)械工程英語(yǔ)口語(yǔ) 篇五
Groups of part program instructions are received from the central computer and stored in buffers.零件加工指令程序由計(jì)算機(jī)接受儲(chǔ)存在內(nèi)存中。
They are then dispensed to the individual machines as required Feedback data from the machines are also stored in the satellite’s buffer before being collected at the central computer.當(dāng)需要時(shí)衛(wèi)星計(jì)算機(jī)發(fā)送指令程序到每個(gè)獨(dú)立機(jī)床中。來(lái)自機(jī)床的反饋數(shù)據(jù)在電腦中央存儲(chǔ)接受之前存儲(chǔ)在衛(wèi)星內(nèi)存中。
Direct numerical control can be defined as a manufacturing system in which a number of machines are controlled by a computer through direct connection and in real time.直接數(shù)據(jù)控制定義為一個(gè)制造系統(tǒng)，一定數(shù)量的機(jī)床有一臺(tái)計(jì)算機(jī)通過(guò)直接硬件連線實(shí)時(shí)控制。
The tape reader is omitted in DNC, thus relieving the system of its least reliable component. Instead of using the tape reader, the part program is transmitted to the machine tool directly from the computer memory.相應(yīng)的磁帶播放機(jī)忽略在直接數(shù)控中，這樣就消除系統(tǒng)中最不可靠的環(huán)節(jié)。不用磁帶播放機(jī)而用電腦信息傳給車(chē)床。
In principle, one computer can be used to control more than 100 separate machines. (One commercial DNC system during the 1970s boasted a control capability of up to 256 machine tools.) The DNC computer is designed to provide instructions to each machine tool on demand When the machine needs control commands, they are communicated to it immediately.原則上說(shuō)一臺(tái)計(jì)算機(jī)可以控制獨(dú)立機(jī)器。DNC系統(tǒng)在1970 年稱為可控制26 臺(tái)機(jī)床直接數(shù)控，DNC電腦設(shè)計(jì)成在需要的時(shí)候提供指令給每一臺(tái)機(jī)床，當(dāng)機(jī)床需要控制指令時(shí)，計(jì)算機(jī)立即發(fā)送指令給機(jī)床。
