摘要
提出了一种从设计模型中提取制造特征的方法,利用STEP中性文件重构零件模型,进一步利用目标面上的环数建立制造特征的类关系图,即可实现从设计模型中提取制造特征.
A method of extracting machining features from the designed model is presented. Through STEP neutral format, the parts model is reconstracted and the number of loops in the target surface is used to build up the class relationship diagram so that machining features can be extracted from the designed model.
