III、Translate the following paragraph into Chinese:（50分）
Rational for CAD/CAM (1) Increased Production. Productivity in the design process is increased by CAD/CAM. Time-consuming tasks such as mathematical calculations, data storage and retrieval, and design visualization are handled by the computer, which gives the designer more time to spend on conceptualizing and completing the design. In addition, the amount of time required to document a design can be reduced significantly with CAD/CAM. All of these taken together means a shorter design cycle, shorter overall project completion time, and a higher level of productivity. (2) Better Quality. Because CAD/CAM allows designers to focus more on actual design problem and less on time-consuming, nonproductive tasks, product quality improves with CAD/CAM. CAD/CAM allows designers to examine a wider range deign alternatives (e.g., product features) and to analyze each alternative more thoroughly before selecting one. In addition, because labor-intensive tasks are performed by the computer, fewer design errors occur. These all lead to better quality. (3) Better Communication Design documents such as drawings, part lists, bills of material, and specifications are tools used to communicates the design to those who will manufactured it. The more uniform, standardized, and accurate these tools are, the better the communication, it improve communication. (4) Common Database This is one of the more important benefits of CAD/CAM. With CAD/CAM, the data generated during the design of a product can be used in producing the product, this sharing of a common database helps to eliminate the age-old “wall” separating the design and manufacturing function. (5) Reduced Prototype costs. With manual design, models and prototypes of a design must be made and tested, adding to the cost of the finished product. With CAD/CAM, 3-D computer models can reduce and, in some cases, eliminate the need for building expensive prototypes, such CAD/CAM capabilities as solids modeling allow designers to substitute computer models for prototype in many cases. 广东工业大学试卷参考答案及评分标准 ( B ) 课程名称: 专业英语（3）

1、Trimming may also be used to remove some of the draft material thereby producing straight side walls on the part.（6分）
修边同时也用来切除拔模斜度产生的多余材料以获得直边。

2、The power supply provides a voltage potential between the electrode and the die block such that, when the gap between the two is sufficiently small, a spark passes through this gap. （6分）
模块和电极都接通电源就会有电压，当电极和模块之间的间隙足够小时，电压会产生电火花击穿这个间隙。

3、The most important problem in the process of injection molding is undoubtedly the correct design of the injection mold, because the molding shop has little influence, if any, on the construction of the machine. （6分）
因为成型车间没什么影响，即使有，也是注塑机的结构的影响。因此， 注射成型工艺最重要的问题无疑是正确设计模具。

4、The flywheel , which is driven by an electric motor and “V” belts, stores energy that is used only during a small portion of the crank revolution, namely during deformation of the material. （6分）
飞轮由电机和三角皮带驱动，飞轮积聚的能量仅在曲柄转动的小部分范围，即材料变形的时候才释放出来。

5）The strip steel stock used in steel rule dies varies between 1.4 to 4.22 mm thickness and the shearing edge side is grounded at a 45°bevel.（6分）
用于钢带模的钢条厚度在1.4~4.22毫米范围，且剪切刃口磨成45°的斜角。

III、Translate the following paragraph into Chinese:（50分）
CAD/CAM的特点 1）
提高生产率 通过应用CAD/CAM，提高设计效率。如数学计算、数据的储存和提取、设计结果的显示等这些高度耗时的工作都给计算机处理，这就给设计者更多的时间去构思和完成设计。用CAD/CAM可明显缩短文件所需的时间。所有这些结合起来意味着设计的周期更短、完成整个项目的时间更短、生产率更高。（10分）
2）
提高产品质量 由于CAD/CAM 能让更多的关注设计的实际问题和减少消耗在非生产任务上的时间，所以利用CAD/CAM能提高产品质量。CAD/CAM使设计者能在更大的范围作选择（如：产品的特性）以及在选择前作更全面地分析。另外，大量的重复性劳动由计算机完成，设计中产生的错误更少，产品质量提高。（10分）
3）
更好的交流 设计文件如图纸、零件目录、材料清单、说明书都是设计者和制造者的交流工具。这些文件越统一、越标准、越准确，交流就越好。由于CAD/CAM能形成更统一、更标准、更准确地的文件，所以能促进交流。（10分）
4）
数据库共享 这是CAD/CAM最大的优点之一。有了CAD/CAM在设计产品中产生的数据可在生产过程中使用，公用的数据消除了长久以来设计和制造分离的壁垒。（10分）
5）
降低模型成本 手工设计时，设计的模型或样品都必须制造出来并试验，这样增加了产品成本。而使用CAD/CAM，在某些情况下可减少三维计算机模型，不必建造昂贵的样品，在许多情况下，CAD/CAM能让设计者采用计算机的造型显示来代替实体原型。（10分）
