This paper presents a new methodology for multi interpretations of feature model in a general way. Based on the information of features in the machining feature model, all possible machining features and machining feature models are generated. The algorithm is following by three steps. Firstly, the Total Delta Volume (TDV) which must to be removed for producing a part is decomposed into Minimal Machining Volumes (MMV). Secondly, all possible machining features of the part are generated by feature hints that are left on the minimal machining volumes. In order to generate all possible machining feature models, a equation is constructed after all machining features are represented by vectors. By this equation all the possible machining feature models can be got without drop.
