针对切削加工过程中切屑折断随机性较大,切屑折断过程所获得的知识带有不确定性或不精确性这一特点,在刀片槽型专家系统DPCXES—1中,利用专家系统开发工具OPS83所提供的数学模型,实现了不精确推理.并设计了带有可信度的事实和规则的表,不精确推理冲突消解策略和记忆推理链、相同事实的可信度归一. In view of the fact that chip breaking randomness is large in the cutting process and the knowledge gained by the chip breaking process is uncertain or inaccurate, in the slotted slot expert system DPCXES-1, the expert system development tool OPS83 Provided the mathematical model, inaccurate reasoning was implemented, and the table of fact and rules with credibility was designed, the conflict resolution strategy and the memory inference chain were not inaccurately deduced, and the credibility of the same facts was normalized.
