| 摘 要： | 以某型航空发动机钛合金整体叶盘的数控铣削为研究对象，提出了一种面向航空发动机整体叶盘的数控铣削刀具性能灰色综合评价方法。首先设计涵盖航空发动机整体叶盘难加工特征的基准件模型，然后基于灰色关联度分别构建了粗精加工刀具性能灰色综合评价模型，最后进行基准件的切削试验并应用所建立的灰色综合评价模型对刀具性能进行综合评价。研究结果表明，所构建的基准件模型和灰色综合评价模型可以快捷、有效地评价刀具性能。

| Abstract: | A grey comprehensive evaluation method of CNC milling tool performance was proposed for an aeroengine titanium alloy blisk with the CNC milling of a type of aeroengine blisk as the research object. In this method, a benchmark with some typical difficulttomachine features extracted from aeroengine blisk was designed, and the processing route was developed. In addition, grey comprehensive evaluation models of cutting tool performance were established for roughing and finishing tools respectively. Finally, experiments of CNC milling the benchmark were carried out, and then the grey comprehensive evaluation models were used to evaluate the cutting tools. The results show that the method is convenient and effective to evaluate the cutting tool performance for aeroengine blisks. |
