【正文】 這架飛機直接從CAD/CAM 軟件開發(fā)（增強 CATIA 系統(tǒng)）并沒有建立原型或?qū)嵨锬Ｐ偷那闆r下制造出來，如以前所需要的的模型。 The emergence of CAD/CAM has had a major impact on manufacturing， by standardizing product development and by reducing design effort， tryout， and prototype work； it has made possible significantly reduced costs and improved productivity. The twoengine Boeing 777 passenger airplane， for example, was designed pleted by puter（ paperless design ） .The plane is constructed directly from the CAD/CAM software developed（ an enhanced CATIA system） and no prototypes or mockups were built ， such as were required for previous models. CAD/CAM 的出現(xiàn)對制造業(yè)產(chǎn)生了重大影響，通過產(chǎn)品開發(fā)的標準化和減少設(shè)計工作量，試用，和原型的工作；它有可能大大降低成本和提高生產(chǎn)力。刀具路徑可以隨時修改，以適應(yīng)其他部分的形狀被加工。指令（程序）是計算機生成的，它們可以由程序員修改優(yōu)化刀具路徑。計算機輔助設(shè)計研發(fā)期間存儲在數(shù)據(jù)庫，然后通過計算機輔助制造進一步處理，一直到必要的數(shù)據(jù)和指令的操作和控制生產(chǎn)機械、物料搬運設(shè)備，自動化測試和檢驗產(chǎn)品質(zhì)量。計算機輔助設(shè)計和計算機輔助制造常常是和 CAD / CAM系統(tǒng)相結(jié)合的。利用這些信息，設(shè)計師可以分析備選設(shè)計的經(jīng)濟性。通過有限元分析，應(yīng)力加到計算機模型上并且以圖形化的方式顯示其結(jié)果，在產(chǎn)品物理原型生產(chǎn)之前，對設(shè)計中的任何內(nèi)在問題給設(shè)計者一個快速的反饋。對于具有不同特性的零部件，如移動或靜止，可以指定不同的顏色在顯示屏上標示。 CAD makes possible multiview 2D drawings ， and the drawings can be reproduced in different levels of reduction and enlargement. It gives the mechanical engineer the ability to magnify even the smallest of ponents to ascertain if as
