, 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)。 In machining operations, an important feature of CAD/CAM is its capability to describe the tool path for various operations, such as NC turning, milling, and drilling. The instructions ( programs) are puter generated, and they can be modified by the programmer to optimize the tool path .The engineer or technician can then display and visually check the tool path for possible tool collisions with fixtures or other interferences. The tool path can be modified at any time, to acmodate other part shapes to be machined. 在機械加工中, CAD/CAM 的一個重要特征是它有可以描述刀具運動軌跡的能力,如數(shù)控車削,銑削,鉆孔。工程師或技術(shù)員可以顯示和檢查刀具路徑可能與夾具或其他干擾工具碰撞。 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,計算機數(shù)控編程和工業(yè)機器人;( 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工作站上的坐標測量機編程;( d)工藝規(guī)劃與調(diào)度;和( e)工廠布局。例如雙引擎的波音 777 客機就是由計算機設(shè)計完成(無紙化設(shè)計)。
