摘　　要：为实现以三维工序模型为核心的三维工艺构建,基于从毛坯模型到最终产品模型的演进过程,对三维工序模型的生成方法进行研究。在制造特征信息模型的基础上,结合基准信息建立了面向工序模型生成的工序信息模型。提出制造特征信息在工序模型中的映射机制,解决该模式下工序模型信息缺失的问题。以工序信息模型为模板,首先定义加工特征基元,然后通过实例化实现工序模型的变换。最后,通过集成工艺决策系统,构建三维工序模型生成系统,为后续工艺尺寸标注和工艺展示提供模型支持。In order to construct three dimen-sional （3D） manufacturing process plan with 3D process models, from the perspective of real machining process, a methodology of generating the 3D operational model for manufacturing process operations is proposed. Based on a proposed manufacturing feature information model and the datum information, an operational information model is established. To avoid the absence of information in the operational model, a mechanism of information mapping from manufacturing feature information to the operational model is created. Taking operational information model as a template, manufacturing feature elements are defined and instantiated to carry out the evolutionary construction of the operational models. Finally a 3D operational model generation system is achieved by integrating the process planning system to support further process dimension an- notation and demonstration.
