a physical prototype. 隨著三維建模的出現(xiàn)設(shè)計(jì)師有了更多自由和無(wú)限制的修改它們以實(shí)現(xiàn)所期望的結(jié)果。 In addition to the design’s geometric and dimensional features,other information ( such as a list of materials, specification , and manufacturing instructions) is stored in the CAD database. Using such information ,the designer can then analyze the economics of alternative designs. 除了設(shè)計(jì)的幾何和尺寸特性之外,其他信息 (比如材料清單、規(guī)格、和制造說(shuō)明 )都存儲(chǔ)在 CAD 數(shù)據(jù)庫(kù)里。 Computeraided manufacturing(CAM) involves the uses of puters and puter technology to assist in all the phases of manufacturing a product, including process and production planning,machining , scheduling , management , and quality control. Computeraided design and puteraided manufacturing are often bined into CAD/CAM systems. 計(jì)算機(jī)輔助制造 (CAM)包括使用計(jì)算機(jī)和計(jì)算機(jī)技術(shù)來(lái)協(xié)助制造產(chǎn)品的所有階段,包括工藝和生產(chǎn)計(jì)劃,加工,調(diào)度,管理,和質(zhì)量控制。 This bination allow the transfer of information from the design stage into the stage of planning for the manufacture of a product,without the need to reenter the data on part geometry manually. The database developed during CAD is stored; then it is processed further,by CAM, into the necessary data and instructions for operating and controlling production machinery, materialhandling equipment
