数控机床进给系统静动热分析知识库研究

The Study of Knowledge Base System about the Static,Dynamic and Thermal Analysis in the Feed System of CNC Machine Tools

鉴于数控机床进给系统静动热分析知识量巨大、知识类型复杂和知识技巧多变的特点,进行了数控机床进给系统静动热分析知识库框架结构模型的建立,并在此基础上用面向对象的方法、面向对象的产生式规则方法和流程图和文本相结合的方法进行了相关知识的表示,进而运用知识获取模型1和知识获取模型2进行了知识的获取。

In view of the characteristics of the feed system of cnc machine tools of tremendous amount of knowledge of dynamic and thermal analysis, knowledge of complex types and knowledge of changing skills, it builds the NC machine tool feed system static and dynamic thermal analysis knowledge base flame structure model, on this basis the knowledge representations are realized by using the object oriented technique, production rules and object oriented method and the method of combining text and flowchart, thus the relevant knowledge is acquired getting the model I and model 2.
