Drawing boards and manual drawing a

Drawing boards and manual drawing are not always precise and rapid traditional design is usually slow, especially in its revision and modification. For this reason manufactu ring firms have replaced manual drawing wi th computer-a ided design (CAD) to carry out fu nctions related to design and production. This computer technology assists the designer in the creation, modification and analys is of a physical object. Nowadays computer software can easily provide a three-dimensional drawing, which allows engineering designers to see how mechanical components may fit together without making models thus saving a lot of time. CAD is much faster and more accurate than manual drawing, designs can be quickly modified, reproduced and transmitted electronically. Computer simulated analysis of the model helps experts find problems and defects without building prototypes, in this way saving a lot of money and time. When the design is ready, the CAD system can generate the detailed drawings needed to start product manufacturing. When CAD systems are linked to manufacturing equipment controlled by computers, they form an integrated CAD/CAM system. Computer-aided manufacturing (CAM) offers significant advantages over traditional approaches by controlling manufacturing equipment with computers instead of human labour. CAM converts the design of a component into computer language and it gives instructions to the computer regarding machine operations. Thanks to CAD/CAM systems it is possible to eliminate operator errors and reduce manufacturing costs.

绘图板和手工绘图并不总是精确和快速的，传统的设计通常是缓慢的，特别是在其修订和修改。为此，制造业公司已用计算机辅助设计（CAD）取代手工制图，以开展与设计和生产有关的工作。这项计算机技术帮助设计者创建、修改和分析一个物理对象。
如今，计算机软件可以很容易地提供一个三维图形，这使得工程设计人员可以看到机械部件如何在不制作模型的情况下装配在一起，从而节省了大量时间。计算机辅助设计（CAD）比手工绘图快得多，也更精确，设计可以通过电子方式快速修改、复制和传输。
对模型进行计算机模拟分析可以帮助专家在不建立原型的情况下发现问题和缺陷，这样可以节省大量的金钱和时间。当设计准备就绪时，CAD系统可以生成启动产品制造所需的详细图纸。当CAD系统与计算机控制的制造设备相连接时，就形成了一个集成的CAD/CAM系统。
计算机辅助制造（CAM）通过计算机代替人工控制制造设备，比传统方法具有显著的优势。CAM将元件的设计转换成计算机语言，并向计算机发出有关机器操作的指令。借助于CAD/CAM系统，可以消除操作员错误并降低制造成本。
