基于知识图谱的数控滚齿加工工艺方案的决策方法OA

For the process design of computer numerical control(CNC)gear hobbing,the traditional decision-making methods rely on the experience and knowledge of process technicians,lacking effective organization and manage-ment of process knowledge,which makes it difficult to achieve knowledge sharing and reuse in the formulation of process schemes.This paper proposes a decision-making method for CNC gear hobbing process schemes based on knowledge graphs.The representation methods and computer description methods of rule-based,instance-based and resource-based knowledge in gear hobbing are designed.On this basis,a complete knowledge graph of CNC gear hobbing process is constructed.Using this graph rapid and high-quality intelligent decision-making of processing schemes is achiered.The example of gear hobbing process design verifies the effectiveness of the method.
