摘　　要：针对抽象的机械加工设计意图难以直接用于检索工艺知识,以及在应用中难以描述的特性,在论述加工意图的组成要素的基础上,提出了加工意图多粒度结构化描述方法。通过对加工意图属性域的描述以及结合二维流形的结构化加工拓扑描述,建立了多粒度加工意图在加工过程演变中的描述模型。最后以实例验证,表明多粒度加工意图建模方法的有效性与实用性。For abstract machining design intent is difficult to directly retrieval of process knowledge and difficult to de-scribe properties in the application, this paper presents a structured multi - granularity description method of machining de-sign intent which is based on the constituent elements of processing intent. Through the descriptions of attribute domain forprocessing intent and structured processing topology for two - dimensional manifold, this paper establishes a descriptivemodel of multi - granularity machining design intent in the machining process evolution. Finally, this paper gives an exam-ple to demonstrate effectiveness and practicability of the modeling method of multi - granularity machining design intent.
