And if a file is reduced, it leaves a gap. 如果文件被缩小,就会产生空白间隙。
In order to obtain both geometry and manufacturing information to build product model for parts, it is necessary to develop a feature modeling system. The output information are converted to STEP neutral file to close the gap in CAD/ CAPP/ CAM. 开发特征造型系统,建立包含零件的几何信息和加工信息的信息模型,最后输出STEP中性文件,达到CAD/CAPP/CAM集成。
