Summary:	目前的微細金屬線材，大都以伸線製程完成，伸線係指將金屬線材由粗變細的過程，一般業者使用連續式的抽線機械生產線材產品，且經過多道次眼模抽線製程，達成所需直徑之高品質線材。本文採用有限元素分析軟體DEFORM-2D，模擬微細金屬線材之伸線製程，且研究減少伸線道次以及伸線眼模的磨耗預測分析。研究發現減少道次改良後，能有效降低線材最大等效應變、最大等效應力值，結合延性破裂準則後探討伸線線材，發現延性破壞指數(Damage)會隨著摩擦係數、面積減縮率的增加而增加，並能預測發生延性破裂時機與方位，結合Archard磨耗模式應用於磨耗分析中，發現伸線眼模的最大磨耗量發生在減縮部靠近成形部處，並能預測各道次眼模磨耗量。 In this paper the designs of diamond dies for multi-pass metal alloy wire drawing processes is investigated. A finite element analysis of wire.The results indicate that the reduced drawing process improves the forming force, effective stress and strain. After combined the ductile fracture criteria, the value of ductile fracture on billet is growing with increased friction coefficients and reduction of area. Moreover, it can predict the timing and position when ductile fracture happen. Applied the Archard mode to the wear analysis, which can find the maximum wear quantity of drawing dies occurred at the position of reduction close to bearing, and can predict wear quantity of dies in every pass.
