摘　　要：磨粒流抛光主要用于小尺寸和复杂结构化表面的光整精加工。针对磨料参数选取仅靠其定性选择原则和经验,导致一些工况的磨料选取不合理而严重影响加工质量的问题,提出了一种磨料参数模糊优选的方法。该方法基于模糊数学理论,采用模糊参数优化建立了多目标磨料参数优选模型,结合磨料参数的选择原则和磨料参数之间的影响建立了相对优属度矩阵和权向量,从而量化了不确定性因素。最后,通过实际加工实验验证了该方法的合理性和可行性。Abrasive flow polishing method is mainly applied to polish surface of subsize and complicated structure workpieces. To solve the process technology problem of unreasonable abrasive parameters selection based on experience result in undesirable processing quality, the optimization of a multi-objective fuzzy model of the system used in abrasive parameters was established based on fuzzy mathematics theory. To quantify the uncertainty of the factors, relative optimal subordinate degree matrix and weight vectors were estab- lished taking into account the impact of various factors of abrasive parameters on the principle of selec- tion of abrasive parameters. Experiment was carried out to verify the rationality and feasibility of the opti- mization model.
