【正文】 ed many social and ethical issues. Recently, the Inter has been criticized for its uncensored information, but has been praised for its educational value. In engineering field the inter is used for information dissemination and pany advertising. Today all the big pany offers many information about their products directly on the inter. In the mechanical engineering fields the most panies offer free catalogs about products (free documentation about technical characteristics, free 2D drawings and 3D models), prices, calculus technical software (ex: bearings SKF) etc. On the inter exists dedicated sites for all level of product development. Starting from standard catalogs for elementary parts (screws, bearings, pulleys, belts, gears etc) and finished with plex products (like industrial robots – ) the inter is a useful tool in design process for all kind of products. The disadvantage of the inter is the increasing diversity of information and the way of dissemination. The big problem is how to find utile information in this virtual space on inter. Free 3D gears catalog on inter 167 Finding useful 3D catalogs on inter Today on inter the information is structured into web pages. Almost all the panies in the world have web pages in order to offer more information about their products. There are 3 ways to search: 1 to find a pany into some specific engineering fields. If the name of pany is known usually the site is 。 Style。 關(guān)鍵詞： CAD CAM的 CAE 軟件，互聯(lián)網(wǎng)上的在線目錄，在線 3D 目錄 連接 ，標(biāo)準(zhǔn)要素，集成產(chǎn)品設(shè)計(jì) 緒論 現(xiàn)在，業(yè)內(nèi) 的 高度競(jìng)爭(zhēng) 促使 產(chǎn)生新的，更好，更便宜的產(chǎn)品。 2 – 我們可以 只買一些具體的一攬子關(guān)于電腦輔助設(shè)計(jì)，計(jì)算機(jī)輔助 制造，計(jì)算機(jī)輔助工程 的部分 。 互聯(lián)網(wǎng)的缺點(diǎn)是不斷增加的信息的多樣性和傳播途徑。 另一種是交互式的在線目錄有一些類似的優(yōu)勢(shì)： 1 查找所有的產(chǎn)品（包括 PDF格式的信息）， 2 在線演算軟件， 3，產(chǎn)品可直接到 CAD CAM的實(shí)施 CAE軟件。 （ N/A=無(wú) 輪轂 ）。 利用的 CAD CAM， CAE軟件和互聯(lián)網(wǎng)設(shè)施的產(chǎn)品開發(fā)的主要優(yōu)勢(shì) 是耗費(fèi) 時(shí)間很短， 可以 致力于設(shè)計(jì)過(guò)程。 尺寸 。有兩種類型的網(wǎng)站目錄。 今天，所有的大公司 都在互聯(lián)網(wǎng)上 提供了許多 他們產(chǎn)品的 信息。 這些 軟件的另一個(gè)主要缺點(diǎn)是一個(gè)完整版本的價(jià)格非常高。 POLITEHNICA 大學(xué)， 布加勒斯特機(jī)器和生產(chǎn)系統(tǒng)部， Splaiul Independentei 313 號(hào)，布加勒斯特， ”羅馬尼亞 RO 060042 電 子 郵 件 ： ， ， ， 摘要：產(chǎn)品發(fā)展的主要目標(biāo)是 在 一個(gè)短的時(shí)間 的 設(shè)計(jì)過(guò)程中，獲得低價(jià)格 的產(chǎn)品 和最終產(chǎn)品的最佳表現(xiàn)。 “ball bearings” etc.。 3 to find some specific products (standard or not) for a specific engineering field it is remended to use dedicated portals. A portal is a site which contains information and links to specific sites for a domain. (ex. On inter in the engineering fields the panies presents their products structured in catalogs. There are two types of catalogs on web. One is in wellknown format PDF (portable document format). To find catalog of this type it is remended for searching to use, after specific keywords, the acronym “PDF”. The advantage using a pdf catalogs is that all the needed information about a product is presented into single file, which can be printed. The other is interactive online catalogs which have some advantages like: 1 to find all information for a product (including in pdf format), 2 online calculus software, 3 the product can be directly implemented into CADCAMCAE software.
