基于模糊推理的工件定位表面选择

摘要

Presents the selection of workpiece locating surfaces using Mycin uncertain inference based on fuzzy inference, the analysis of fuzzification of characteristic factors of the candidate surfaces with a suitable fuzzy distribution function, and the algorithm for fuzzy inference based on credible factor (CF) calculation and the case study to check the validity of this method and highlight its performance.%工件定位表面的选择是夹具设计中的重要组成部分，直接影响着工件的加工质量和夹具设计的成败．采用了基于模糊推理的Mycin不精确推理方法，对工件定位表面的选择方法进行了研究．讨论了候选定位表面的表征因素的模糊化方法，给出了候选定位表面表征因素的模糊分布函数，阐述了基于可信度计算的模糊推理算法，并用实例对该方法的有效性进行了验证．
