    Abstract: 利用電化學加工(ECM)方法製造鈦合金整流板,具有工具無耗損、工件表面無殘留應力等優點,但是如何設計工具形狀及工作參數方可將工件加工成所需之形狀卻是一件不易之工作;往往需不斷測試與修改,進而影響生產時間與效率。 本文將使用套裝軟體FORTRAN來建立一套電腦模式,利用有限差分法計算二維電場之分佈,並利用控制體積觀念來模擬熱流場之變化;以期能準確計算出工件形狀與預測出所需工具形狀。 由於電化學加工過程中,電解液的種類、濃度與溫度均對其導電度有很大的影響,而導電度會影響工件之去除率以及加工精度。故本文也以實驗來量測相同電解液(硝酸鈉)在不同的濃度與溫度下的導電度,亦將所得到的數據代入程式運算,使得數值模擬更準確。 The project presents a numerical for predicting the anode shapes in the electrochemical machining with prescribed tool shape. The conductivity of, and the variation of electrolyte conductivity with temperature had been taken into account in numerical simulation. Results show that the accuracy of the predicted shape is improved.
