And this makes it possible and easier for people to do various（各种不同的）difficult machining which couldn’t be done before. Also, it is quite clear that CNC machine tools can often do the jobs more effectively（有效的）than common machines.The following CNC machine tools are mainly used in today’s industry production.According to different machining needs, the general CNC machine tools can also be categorized （把…归类）as CNC lathe, CNC miller, CNC borer, CNC grinder, and CNC driller, and so on.C lathe It is one of the most widely used modern CNC machine tools in today’s industry production. It is designed to cut off the useless parts of material from stock（毛坯，棒料）which is clamped（夹紧）in a rotating （旋转的）spindle（主轴）.Most metal（金属）cutting is done with a sharp（锋利的）single point（单刃）cutting tool. Modern CNC lathes use turrets to hold and move cutting tools. The turret is also used to quickly index（抓取）an old tool out and a new tool into its cutting position. Each tool position on the turret is numbered for identifying（识别）the tool it holds. Tools can be mounted on the face of the turret as well as on its sides. Upon receiving a tool change command（指令）from the MCU, the turret moves to a safe tool change location（位置）and indexes the old tool out and a new tool in. It then proceeds to（继续）the proper coordinates（坐标）programmed for cutting the part with the new tool. It should be stated（指出）that for turning centers with programmable（可编程的）tailstocks, the tailstock might first have to be moved back before a tool change is executed（执行）. The machine tool is equipped with front and rear（后面）turrets, which cause（引起）it possible to execute cutting operations（操作）simultaneously（同时）from the top and the bottom of the work.C milling machine tools There are two kinds of the machines. They are the vertical （竖直的）CNC miller and the horizontal（水平的）CNC miller, which are widely used to machine surface（平面）and contour（外轮廓）machining. They can be used to machine some parts with very complex（复杂的）shape. And they can also do drilling（钻削）, reaming（绞孔）, boring （镗孔）and counter-boring（扩孔）. It must be understood that because of lacking（缺乏）the function （功能）of exchanging（交换）tools, the CNC milling machine tools can’t do the hole machining with high quality requirements.C machining center It is the CNC machine tool that has the function of cutting tools changing automatically（自动地）and is capable of performing multiple（多样的, 多重的）machining operations such as drilling, boring, milling and so on. In the development of machining centers, the horizontal(水平的) machining center came from the milling machine and the vertical（垂直的，直立的）machining center from the drilling machine. It is obvious thatmachining centers save substantial（充足的，大量的）production time and costs by minimizing（使减到最少）the number and complexity（复杂性）of fixtures（夹具）and reducing the number of work stations( 加工设备).1.根据课文判断正误（6分）( ) (1) In the development of machining centers, the horizontal machining center came from the milling machine and the vertical machining center from the drilling machine.( ) (2) Because of lacking the function of exchanging tools, the CNC milling machine tools can’t do the hole machining with high quality requirements.( ) (3) A turret on a CNC lathe is used to quickly change tools when required.( ) (4) The CNC milling machine is one of the most widely used modern CNC machine tools in today’s industry production.( ) (5) The CNC milling machine save substantial production time and costs by minimizing the number and complexity of fixtures and reducing the number of work stations.（）（6）It is quite clear that CNC machine tools can often do the jobs more ineffectively than common machines2. 理解文章内容，翻译以下专业词汇(12分)（1）转塔刀架（2）铣床（3）数控机床（4）tailstock （5）CNC borer (6) turning centers3. 理解文章内容，将文中加粗的句子译成中文(12分)（1）And this makes it possible and easier for people to do various difficult machining which couldn’t be done before.(2) It is designed to cut off the useless parts of material from stock which is clamped ina rotating spindle(3) It is the CNC machine tool that has the function of cutting tools changing automatically and is capable of performing multiple machining operations such as drilling, boring, milling and so on.。

They can be played back，edited，and processed by the controller．All programs resided in RAM，however， are lost when the CNC machine is turned off．These programs can be saved on auxiliary storage devices such as punched tape，magnetic tape，or magnetic disk. The MCU units have graphics screens that can display not only the CNC program but also the cutter paths generated and any errors in the program.
NC technology has found many applications, including lathes, and turning centers, milling machines and machining centers, punches, electrical discharge machines (EDM), flame cutters, grinders, and testing and inspection equipments. The most complex CNC machine tools are the turning center with a ten-station turret that accepts quick-change tools, the vertical machining center that the tool magazine is on the left of the machine and horizontal machining center equipped with an automatic tool changer, shown in Figure 1-1 and Figure 1-2 respectively. Generally speaking, tool magazines can store 200 cutting tools.

C 篇文章根据文章内容,从每小题给的四个答案中选择正确答案.AOperating the NC machineAfter starting the NC machine, the operator can freely change the position of the tool by pressing buttons. It is possible to move the table either very fast or very slowly. A desired increment can also be made as small as a fraction of a thousand of a millimeter.By jogging, the operator brings the tool to the reference position and sets this position through the control panel. The NC tape is now fed into the tape reader section of the machine control unit. A press of a button in automode enables the machine tool to machine the blank and allow the desired error. During the machining of the workpieceit can be observed that the machine tool stops now and then and the operator needs to refer to the part program. During these stops either he may turn to check if everything is going on all right or he could change the tool for the next cutting operation. After these temporary stop overs, the machine cycle could again be started from the control panel. The machine can also be operated.61. The position of the machine tools can be changed.62. Coordinate are used to locate the position.63. The machine tool stops from time to time during machining.64. After checking to the stops, the machine can work properly again.65. The conventional machining skill of the operator thus gets replaced.BA successful operatorAs an operator, it is important to know how your NC is constructed. Understanding your machine will help you greatly. Just as the race car driver needs to understand the basics of his car in order to get the best performance out of it, the NC operator must also understand the basic workings of his machine.Before you start to operate an NC machine tool, you should read the machine tool builder’s manual, and find the answers to the following questions about the capacity and construction o f NC machines.How many spindle ranges does the machine have?How many tools can the machine hold?What is the machin e’s maximum speed rate?There are but a few of the questions you should ask yourself as you begin working with any new NC machine. Truly, the more you know about your machine, the easier it will be to get comfortable with it. 66. MCU is part of a numerical control machine tool.67. It is unimportant for an operator to know the machine.68. A slanted bed provides better and easier access.69. The slanted bed construction is quite rigid.70. The more you know about a machine, the more difficult it is for you to work onit.CMr. and Mrs. Green were living in the country. Each of them had a car. One day Mr. Green wanted to go to an office in the city. He found the address on a letter, got into his car and drove to the city. He drove straight to the office without any trouble and stopped in front of the door. He locked his car and started to go into the offi ce, but then he turned round and went back to his car. “I’ve locked my keys in my car!” he said to himself. He called his wife and said , “Excuse me, but I’ve locked my keys in my car. Please give me your keys.”Mrs. Green got into her car and drove twenty miles to help her husband. But while he was waiting for her, he walked around his car and tried the other door. It was not locked! He locked it quickly before his wife arrived.71.

In recent years, however, the term machining center has come to be associated almost exclusively with a single machine, usually incorporating automatic tool changing, a rotary table which facilitates circular machining, and one or two integral worktables. Such a machine is usually designed to perform operations on at least four and sometimes five surfaces. There are some machining centers with automatic tool changes in vertical and horizontal configurations. A typical machining center may use 50 or more tools.加工中心的概念是使机床处于工作状态。

As it is traced, the various points on the drawing are converted into X-Y coordinates and stored in the computer. Once the drawing has been completely traced, the stored X-Y coordinates define the part and can be fed to an NC machine to provide instructions on tool positioning and movement.2As stated, the goal of all CAM systems is to create a workable CNC program that will machine a workpiece to be run on a CNC machine tool. As with conversational CNC controls, two programs will be involved, the CAM system program and the CNC program. Also, as with conversational CNC controls, the CNC program is created by the CAM program.3These tools are usually stored on drum, chain and “egg box” type of magazines. The drums and chains can be moved to the selected positions. The chains may follow “M” type of path instead of the shown rectangular one. The chain magazine is also mounted on the top or on the side of the machine tool in some versions. The magazine dose not move in this case, instead the movement of spindle and slides brings the tool to the desired positions.。
