英语翻译
For many years automated manufacturing systems were synonymous with MRP (Material Requirements Planning).Today computer-aided design/computer-aided manufacturing are also important components of most manufacturing systems.Product designers and engineers working on computer=aided design (CAD) systems use a powerful computer graphics workstation outfitted with programs that allow them to draw design specifications on the display screen.Manipulating a light pen,scanner,or mouse,they can specify the product’s dimensions and show its lines,indentations,and other features with precision.Each element of the design appears on the screen as it is specified.Changes can be made quickly by adding,removing,or altering details on the drawing.

答案

2楼不厚道,用软件瞎搞...
这么多年的制造自动化系统已经和材料资源计划(mrp)同义了,现在计算机辅助设计/计算机辅助制造也是大部分制造系统的重要零部件了.产品设计者和工程师工作的计算机辅助设计(CAD)系统上面配备了强大的电脑图形工作站,程序允许他们在显示屏上画出规范的设计.只要熟练的使用光电笔,扫描仪,或者鼠标,他们就可以指定产品的纬数,并用线条表现出来,锯齿状和其他的形状都可以很精确的表示.每个元素的设计呈现在屏幕上就如给定的一样,通过在图画上增加,移动,或者改变细节都可以很快的改变设计.
