摘　　要：基于加工特征的定义与分类,将零件分解为一系列加工特征集合,在嵌入式特征模型的基础上,对加工特征的信息进行扩展,建立了基于富集加工特征的可拓基元模型及基于XML的描述方法,提出了基于拓展混合图论与启发式算法相结合的装夹规划方法,并通过标准实例验证了该方法的可行性与有效性.According to the definition and classification of machining feature（MF）, the part was decom- posed into machining feature set. The information of MF was expand based on the embedded feature model, and formed enriched machining feature（EMF）. Then the extended element model（EEM） and XML description method were proposed to support its implementation. Using extended-hybrid graph theory and heuristic algorithm, a new approach of setup planning for RMT configuration synthesis was proposed. Finally, a standard case study was used to validate its feasibility and effectiveness.
