在許多非傳統加工微加工中，微電化學(Electrochemical Micro-Machining，EMM)擁有加工速度快、無表面應力殘留及表面光潔度佳的優勢，具有相當的發展潛力和高附加價值。
本研究採用510μm之鎢棒作為刀具，並且利用田口統計方法探討微電化學加工參數(操作電壓、加工能率、刀具轉速、電極間隙及電解液濃度)對於製作微圓柱電極刀具和金屬移除量的影響性程度，在運用穩健設計法加以評估設計最佳參數組合。
由變異數分析法(Analysis of Variance，ANOVA)加以分析，發現操作電壓及電解液濃度的改變將嚴重影響製作微圓柱電極刀具和金屬移除量的結果，同時從研究中順利取得一組最佳參數。

In numerous non-traditional, micro-machining, the electrochemical micro-machining (EMM) has the advantage of quick processing speed, no residual stress in surface, and nice smoothness in workpiece surface with enormous potentialities highly added value.
A tungsten filament with 510-micron meter of diameter is selected as electrode tool, and Taguchi Statistical Method of Quality-engineering is used to analyze the influence level on fabricating micron-column electrode tool and material removal rate by parameters(Such as : voltage, duty, rotation, gap, electrolyte concentration).Robust-Design technique is also used to estimate the best design combination of parameters in our experiment.
By analyzing the Analysis of Variance(ANOVA), the voltage and electrolyte concentration are found to affect apparently the fabricating micron-column electrode tool and material removal rate, and the best parameter combination is simultaneously acquired from the research.
