Computers have been used in nearly every manufacturing job. Computers improve the efficiency, accuracy, and productivity of many manufacturing processes. Just like the other tools and machines, computers extend human capabilities and make some job easier. Every department in manufacturing has found a use of computers. 电脑已经使用在几乎每一个制造业工作。电脑提高效率、精度和生产率的生产流程。就像其他工具和机器,电脑更容易扩展人类的能力和做一些工作。每个部门在制造业找到了计算机的使用。 In the management department, supervisors and managers use computers to gather information about the progress of work in all the other departments. In marketing, researchers, advertisers, and sales people use computers to get data on potential buyers, to study market research, and to creat advertisements. 在管理部门，主管和管理者使用计算机收集有关其他部门工作进展情况的信息。在营销方面，研究人员、广告主和销售人员使用计算机来获取潜在买家的数据，研究市场研究，并创造广告。 The real tool when using any computer is the software. Software is the set of coded instructions written to control the operations of the computers. Without software, a computer would be a useless machine. The list of written instructions in software is called program. Many software programs are available for every department in manufacturing, but the most important uses of computers have been in the engineering and production departments. 使用任何计算机时，真正的工具是软件。软件是一组编写的代码指令来控制计算机的操作。如果没有软件，计算机将是一个无用的机器。软件中的书面指令列表称为程序。许多软件项目都可用于制造，但最重要的用途是计算机在工程和生产部门。 CAD.?Drafters use CAD systems to make technical drawings of the product to be manufactured. In the past, drafters worked with T-squares, scales, triangles, and pencils to create these drawings by hand on paper. Today more and more drafters use CAD systems to perform drafting operations. Doing drawings by hand requires a great deal of time. Each line, letter, and shape on a drawing must be created by the drafter. The drafter must have great skill to draw these features exactly the same every time. 计算机辅助设计起草者使用CAD系统进行产品技术图纸制作。在过去，起草者曾与丁字尺，鳞片，三角形，和铅笔来创建这些图纸用手上的纸。今天，越来越多的起草者使用CAD系统进行绘图操作。手工绘图需要大量的时间。每一行，信，和画上的形状必须由人创造的。人必须要画出这些特征完全相同的每一次伟大的技巧。 In
