摘要
作為提高產(chǎn)品開發(fā)效率的重要工具和系統(tǒng)，CAD和PDM（產(chǎn)品數(shù)據(jù)管理）在制造企業(yè)被廣泛應(yīng)用，CAD和PDM兩者之間存在較多的業(yè)務(wù)邏輯聯(lián)系，兩者之間的數(shù)據(jù)共享與應(yīng)用集成能很大程度上提高系統(tǒng)運(yùn)行效率，縮短產(chǎn)品開發(fā)周期，提高生產(chǎn)效率。
以三維CAD 系統(tǒng)Inventor為例，探討了CAD和PDM 系統(tǒng)之間的數(shù)據(jù)共享和應(yīng)用集成技術(shù)，PDM通過CAD的API(Add—In)獲取產(chǎn)品設(shè)計(jì)信息，CAD 通過PDM 的Web服務(wù)獲取產(chǎn)品零部件的“外部”屬性，從而實(shí)現(xiàn)CAD和PDM 系統(tǒng)之間的數(shù)據(jù)共享和應(yīng)用集成。本文研究的主要內(nèi)容包括：PDM與CAD數(shù)據(jù)共享與應(yīng)用集成的系統(tǒng)需求，所涉及到的技術(shù)、標(biāo)準(zhǔn)及其應(yīng)用，PDM與CAD數(shù)據(jù)共享的主要途徑以及PDM與CAD應(yīng)用集成的路線、關(guān)鍵技術(shù)和系統(tǒng)架構(gòu)等。本文提出了PDM與CAD數(shù)據(jù)共享與應(yīng)用集成的系統(tǒng)需求、技術(shù)路線和系統(tǒng)構(gòu)架，給出了關(guān)鍵技術(shù)及其應(yīng)用示范，證明了技術(shù)可行性，提出了系統(tǒng)集成應(yīng)用的前景。為進(jìn)一步研究PDM和CAD的數(shù)據(jù)共享和應(yīng)用集成，實(shí)現(xiàn)兩者應(yīng)用集成打下了技術(shù)鋪熱。

Abstract：CAD&PDM(Product Data Management)have been wildly employed in enterprisesof．In view of the flow of information in industry,CAD＆PDM are locatedin upriver&downriver in product development process respectively,&mey have lotsof relations in business logically．The data—sharing&application integration betweenthe two systems cart result in great improvement in system operation efficiency,shorten the development cycle ofproducts and enhance productivity．
The integration of PDM system and CAD sys—tem needs not only transfer of prerequisite and apprehensibledata but also interoperations between the two systems．Datasharing and application integration are studied between PDMand CAD in this paper，on the base of the instance of three—dimensiona1 CAD Inventor． In which， PDM accesses theproduct design information through the API(Add— In)ofCAD，and CAD gets the product components ”external” at—tribute through W eb service of PDM ，in this way，data sha—ring and application integration between PDM and CAD come
true．The main contents of this article include--the system requirements fordata-sharing&integration between PDM&CAD，involved techniques，standards&their application，the main approaches to，key techniques&system structure ofdata-sharing&system integration between them．The article puts forward the system requirements，technical courses&systemarchitecture for data•sharing&application integration between PDM&CAD，presents the key techniques&their examples．proves the technical feasibility＆brings forward a future for integrated application of systems．And it brings a technicalbase for further research on data-sharing&application integration of PDM&CAD．&for eventually realizing integrated application between the two systems．

Key words：CAD／PDM；data sharing；application integration
