| 摘要: |
| 针对机加工工艺设计中的机床优选问题,提出一种基于加工能力元的机床优选方法。将加工能力元作为描述机床加工能力的最小单位,根据工序加工要求,从加工能力元库中查询符合条件的加工能力元。采用基于区间数的FCM聚类算法对查询结果进行量化分析,通过计算工序约束与各聚类中心的匹配度,确定优选加工能力元集合,最终根据机床与加工能力元的对应关系得到优选机床集。通过实例分析,验证了所提方法的合理性和有效性。 |

| Abstract: |
| In mass customization mode,in order to select quickly and accurately the suitable machine tool in ma-chining process design,we present an optimal selection method based on the machining capability element(MAE).We take the MAE as the smallest unit to describe machining capacity of machine tools; then,according to processmachining requirements,we query the MAEs in MAE library. We do three things:(1)using interval valued FCMalgorithm,we perform the quantitative analysis of machining capacities among different machine tools;(2)throughcomputing the matching degree between process machining constraints on the one hand and cluster centers on theother,we get the most suitable MAE set for the process;(3)according to the correspondence between machine toolson the one hand and MAEs on the other,we get the most suitable MAE set for the process. Through case analysis,the rationality and validity of the proposed method were verified. |
