tual assembly and produce engineering drawings, and other functions, can carry out simulation, the mechanism motion analysis, dynamics analysis and finite element analysis, can be used in puteraided manufacturing, generating nc code directly used for processing products. UG to better adapt to the modern mechanical design automation trend, using it can realize the whole process control of the parts design, improve the efficiency of the ponent design and level. UG CAD module is one of the important ponent of the UG. It will feature modeling technology based on constraint and want to bine the traditional geometric modeling technology, has very powerful modeling function. This topic introduces a notebook design and manufacture of the fan, UG NX operating system supported by CAD/CAM software is a powerful modeling and processing functions, greatly improving the product design quality and design efficiency.KEY WORD :CAD/CAM software UG CAD module Entity modelling 目錄第一章 前言 1第一節(jié) CAD/CAM在我國工業(yè)中的運用 1第二節(jié) CAD/CAM在我國運用的幾個階段 1第三節(jié) CAD/CAM在我國的發(fā)展趨勢 2第二章 實例 4第一節(jié) 散熱風(fēng)扇的草圖設(shè)計 4第二節(jié) 散熱風(fēng)扇的三維設(shè)計 5結(jié)論 13致謝 14參考文獻(xiàn) 15第一章 前言第一節(jié) CAD/CAM在我國工業(yè)中的運用當(dāng)今的機械制造業(yè)已不是傳統(tǒng)意義上的機械加工,而是集機械、電子、光學(xué)、信息、生物、能源、管理等學(xué)科最新成就為一體的新技術(shù)綜合體。從硬件上看,由于受“巴統(tǒng)”限制,國外所以高科技設(shè)備必須把通過巴黎技術(shù)統(tǒng)籌委員會審查才能向中國出口,這就造成我們使用的硬件和軟件的過程中,經(jīng)費的絕大部分都用在硬件上,而軟件的投資一般只占一個零頭。從1995年我國進(jìn)人“九五”計劃階段起, CAD/CAM的應(yīng)用也進(jìn)人了新的時期。隨著計算機技
