摘要

摘要: 雷达图法可以对材料切削加工性进行定性评判和定量评价，但尚有指标赋权和有效评价这两个关键问题未得到很好解决。运用数理统计原理对主、客观赋权法得到的指标权值分别处理，基于组合权值与原主、客观值之间的偏差综合最小的优化思想，得到各项指标的组合权值，解决了雷达图中指标赋权问题。定义了包含雷达图周长与面积特征向量的综合评价指数K，对材料切削加工性进行有效的定量评价。最后给出了Ti6Al4V钛合金、AISI316L不锈钢、P20塑模钢、20钢和正火45钢的材料切削加工性评价实例。应用实例验证了本文方法的可行性、合理性和有效性。

Abstract: Using the radar-graph method, material machinability could be evaluated qualitatively and quantitatively. However, there are still two key problems to be resolved, which is the index weight determining and effective evaluation. The comprehensive evaluation method was proposed to solve the first question. The mathematical statistics method was used to process the weight of index, which was decided by the subjective or objective weighting method. The optimization model was established based on the minimizing the total deviations between the original evaluation weight and the combination weight. And the comprehensive evaluation index K contained the area vector and the perimeter vector of radar graph was defined to evaluate the material machinability quantitatively. The machinability examples of Ti6Al4V titanium alloy, AISI316L stainless steel, P20 plastic mould steel, 20 steel and normalized 45 steel were provided finally. The verification results verify the feasibility, reliability and validity of the method.
