摘要
特征识别是实现CAD/CAM无缝集成的重要手段.作者采用基于痕迹的几何推理方法并结合STEP文件信息模型的特点研究了对STEP文件进行特征识别的具体方法和策略,很好地解决了相交特征的识别问题,针对STEP-NC中的制造特征成功地识别出典型的二轴半制造特征:槽、孔和型腔.
Feature recognition is an important means of seamless integration for the realization of CAD/CAM.This paper used hint-based geometry induced method combing the STEP feature to recognize manufacturing information from the STEP files,the specific methods and strategies solved the recognition problems of intersection feature.This paper recognized typical two5D_manufacturing_features of STEP-NC manufacturing features： slot,hole and pocket successfully.
