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, and automated testing and inspection for product quality. 這種組合允許一個產(chǎn)品的信息從設(shè)計階段傳遞到加工規(guī)劃階段,而不需要手動重新輸入幾何部件的數(shù)據(jù)。因而設(shè)計者可以提供多種工程分析并且可以識別潛在的問題(如過負(fù)荷或變形)。它可以從圖形庫中恢復(fù),可以被復(fù)制,拉伸,改變大小,和其他許多方面的改變而無需重新繪制。刀具路徑可以隨時修改,以適應(yīng)其他部分的形狀被加工。計算機(jī)輔助設(shè)計和計算機(jī)輔助制造常常是和 CAD / CAM系統(tǒng)相結(jié)合的。當(dāng)使用 CAD 系統(tǒng)時,設(shè)計者可以使對象概念化以便更容易在圖形屏幕上設(shè)計,并且可以考慮替代設(shè)計或快速地修改一個特定的設(shè)計來達(dá) 到必要的設(shè)計要求或變化。剪切和粘貼技巧作為節(jié)省勞力的助手被使用。 Some typical applications of CAD/CAM are:( a) programming for NC, CNC, and industrial robots;( b) design of tools and fixtures and EDM electodes ;( c) quality control and inspection, for instance,coordinatemeasuring machines programmed on a CAD/CAM workstation;( d) process planning and scheduling ; and( e) plant layout. CAD / CAM的一些典型應(yīng)用是:( a)數(shù)控編程,計算機(jī)數(shù)控編程和工業(yè)機(jī)器人;( b)工具和夾具以及電火花電極的設(shè)計; ( c)質(zhì)量控制和檢查,例如,在CAD / CAM工作站上的坐標(biāo)測量機(jī)編程;( d)工藝規(guī)劃與調(diào)度;和( e)工廠布局。 Computeraided manufacturing(CAM) involves the uses of puters and puter technology to assist in all the phases of manufacturing a pro
