【正文】 y rises dramatically. When something is drawn once， it never has to be drawn again. it can be retrieved from a library ,and can be duplicated, stretched, sized, and changed in many ways without having to be redrawn。 Designers have even more freedom with the advent of 3D parts and manipulate them in endless variations to achieve the desired results. Through finite element analysis ， stresses can be applied to be a puter model and the results graphically displayed， giving the designer quick feedback on any inherent problems in a design before the creation of 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限制的修改它們以實(shí)現(xiàn)所期望的結(jié)果。 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(jī)械加工中， CAD/CAM 的一個(gè)重要特征是它有可以描述刀具運(yùn)動(dòng)軌跡的能力，如數(shù)控車削，銑削，鉆孔。
