摘　　要：提出了一种陶瓷材料磨削加工性综合评价的新方法。基于区间分析及灰色理论,选取陶瓷材料力学性能参数作为磨削加工性的影响因素,构建区间数样本矩阵,计算区间数绝对灰关联度矩阵,由特征向量确定因素权重,得到影响因素的重要度排序以及陶瓷磨削加工性综合评价值。应用本方法对七种典型工程陶瓷材料的磨削加工性进行综合评价,评价结果客观、全面。可以为陶瓷材料的设计、合理选择陶瓷材料及加工工艺参数提供参考依据。A new comprehensive evaluation method of grindability of ceramic materials was proposed. To select mechanical proper- ty parameters of ceramic materials as factors affecting grindability, establish interval sample matrix, calculate interval grey rela- tional coefficient matrix, and determine factor vectors by eigenvector based on interval analysis and grey theory. And then, to get the rank ordering of importance and comprehensive assessment of ceramic grindability. Seven typical engineering ceramic materi- als comprehensively by using the method produce an objective and comprehensive result. This will provide reference for the design of ceramic materials, reasonable selection of ceramic materials and processing technique parameters.
