STEP和XML技术在制造业信息化中的应用

Apply STEP and XML in Manufacturing Information

在制造业信息化实施中 ,必然会应用网络技术 ,要求产品信息的集成和共享扩展到不受时间和空间的限制。STEP可以成为设计和制造之间的桥梁 ,而XML则是网络数据的载体。根据产品制造的需要 ,将CAD系统的输出以相应STEP中性文件的形式存储起来 ,以利用STEP技术共享制造过程中的产品信息 ,但是它不能在网络上显示和表达。通过STEP XML的转换过程 ,建立XMLSchema库 ,将STEP所存储和表达的产品数据再以XML的形式存储和表示在网络上 ,最终可以利用XML实现多系统之间产品数据的网络传输。

During actualization of manufacturing information, the network technology must be applied. The unlimited integration and sharing of product data are required through Internet. STEP can become the bridge between designing and manufacturing. At the same time, XML is the carrier of product data in the net. The product information can be saved while CAD system output STEP files according to the demands of manufacturing. Thus the product information can be shared during the manufacturing process. But it cannot display or express through the Internet. By transforming, according to the certain standard, XML Schema base can be set up. The product data saved and expressed in the STEP file can be stored and existed in XML file. Finally, it can be realized with XML to transform data through Internet.
