1.常用的机械工程英语口语 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车床的能力。

　　the outward appearance of a CNC system is similar to that of a conventional NC machine.CNC的外部系统与传统的NC机相似。

　　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.与传统的数控系统比,纸带通过纸带阅读机对每个批次的工件循环。MCU读取磁带上的指示块,执行该块,然后进行下一个块。

　　In CNC, the entire program is entered once and stored in computer memory.在数控中,整个程序一旦进入并储存在电脑的存储器中。

2.常用的机械工程英语口语 篇二

　　The machining cycle for each part is controlled by the program contained in memory rather than from the tape itself.每个零件的加工周期控制在内存中,而不是来自磁带本身的程序。

　　Control algorithms contained in the computer convert the part program instructions into actions of the machine tool (or other processing equipment).在计算机中的控制算法转换成机床或其他加工设备的行动的一部分程序指令。

　　Certain functions are carried out by hard-wired components in the MCU.MCU中进行硬连接组件的某些功能。

　　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,圆弧插补计算往往是通过硬连接的电路,而不是由存储程序执行。另外,硬件接口需要与机床伺服系统连接。

3.常用的机械工程英语口语 篇三

　　Since the introduction of DNC, there have been dramatic advances in computer technology.由于DNC技术的介入,在计算机技术上得到了很大的发展。

　　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.计算机在尺寸和成本显著减少的同时,计算机的能力却有很大的提高。

　　In numerical control, the result of these advances has been that the large hard-wired MCU of conventional NC have been replaced by control units based on the digital computer.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.在数控中,这些发展使得由硬件布置的MCU变为数字电脑控制的控制单元。最早,小型机在1970 年使用。

　　As further miniaturization occurred in computers, minicomputers were replaced by today's microcomputers.随着计算机进一步小型化,小型机被当今的微型机取代。

　　Computer numerical control is an NC system using dedicated microcomputer as the machine control unit.计算机控制也是一种数字控制,它采用微型计算机作为控制单元。

　　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 电脑接受和发送指令数据都是来自许多机器,CNC电脑控制只是一个机器或多个机器。

　　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 电脑占有一个位置通过控制来实现机器的旋转。CNC电脑要非常靠近车床。

　　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 软件的发展不经可以控制生产设备的每个单独零件,还可以在生产坚固性方面提供主要控制信息。

4.常用的机械工程英语口语 篇四

　　The computer calls the part program instructions from bulk storage and sends them to the individual machines as the need arises.计算机从海量内存中取出部分程序指令送入到需要的独立机床中。

　　It also receives data back from the machines.相应的计算机也接受机床反馈信息。

　　This two-way information flow occurs in real time, which means that each machine’s requests for instructions must be satisfied almost instantaneously.这种双工的信息流在实时控制加工系统中出现意味着每台机床需要指令的请求能立即得到回应。

　　Similarly, the computer must always be ready to receive information from the machines and to respond accordingly.类似的，计算机必须总是要准备要接受信息和进行回应。

　　These satellites are smaller computers, and they serve to take some of the burden off the larger central computer.卫星计算机是更小的计算机 可以分担中央计算任务 减轻其负担。

　　Each satellite controls several machines.每台卫星控制几台机床。

5.常用的机械工程英语口语 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计算机接受储存在内存中。

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.当需要时卫星计算机发送指令程序到每个独立机床中。来自机床的反馈数据在电脑中央存储接受之前存储在卫星内存中。

　　 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.直接数据控制定义为一个制造系统，一定数量的机床有一台计算机通过直接硬件连线实时控制。

　　 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.相应的磁带播放机忽略在直接数控中，这样就消除系统中最不可靠的环节。不用磁带播放机而用电脑信息传给车床。

　　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.原则上说一台计算机可以控制独立机器。DNC系统在1970 年称为可控制26 台机床直接数控，DNC电脑设计成在需要的时候提供指令给每一台机床，当机床需要控制指令时，计算机立即发送指令给机床。
