This paper investigates the use of AlO nano-powder-stirred micro-EDM process for generating micro-channels. This study focuses on the effect of critical machining process parameters, such as capacitance levels and nano-powder concentration, on the micro-channel fabrication performance in terms of TWR, MRR, depth, and width. A two-stage nested ANOVA is employed to understand the effect of powder concentration within different capacitance levels. The results show that the powder concentration significantly influences the system's performance in conjunction with the capacitance. At low (100 pF) and high (1000 pF) capacitance, the addition of AlO nano-powder increases the MRR, depth, and width but decreases TWR up to a concentration of 1.0 g/L. A desirability function analysis (DFA) tool identified the best overall performance from 14 experiments, revealing that 100 pF and 1 g/L yield the optimal outcomes.
本文研究了使用AlO纳米粉末搅拌微电火花加工工艺来制造微通道。本研究聚焦于关键加工工艺参数，如电容水平和纳米粉末浓度，对微通道制造性能（包括加工速度比、材料去除率、深度和宽度）的影响。采用两阶段嵌套方差分析来了解不同电容水平下粉末浓度的影响。结果表明，粉末浓度与电容共同显著影响系统性能。在低电容（100 pF）和高电容（1000 pF）时，添加AlO纳米粉末会增加材料去除率、深度和宽度，但在浓度达到1.0 g/L之前会降低加工速度比。期望函数分析（DFA）工具从14次实验中确定了最佳总体性能，结果表明100 pF和1 g/L能产生最佳结果。
