摘要
针对异构系统之间难以解决的产品数据交换与共享问题,深入研究了制造信息资源共享、STEP AP203/AP214文件到AP224文件的转换规则等关键技术。采用STEP标准作为CAD系统的信息输出,提出了通过STEP中性文件转换器把CAD系统输出AP203/AP214文件转换成AP224文件,CAPP系统通过AP224中性文件来获取零件的几何和工艺信息的方法。利用STEPAP28所制定的转换规则,将STEP文件转换为相应的XML中性文件,建立XML schema库,以实现制造信息的数据交换和共享。
To solve the problem of product data exchange and sharing among heterogeneous systems,the key technologies,including manufacturing information sharing,file conversion from STEP AP203/AP214 to AP224 with the conversion ware of STEP neutral files,are discussed.Using STEP standard as information output of CAD systems,the AP203/AP214 file output from CAD systems is transformed to AP224 file with STEP neutral file,while CAPP systems obtained geometry and manufacturing process information of the parts with AP224 neutral files.By translating the STEP files into corresponding XML neutral files according to the transformation criterions constituted by STEP AP28,XML schema library is setup.Upon this,product data exchange and sharing of manufacturing information can be achieved.
