dc.description.abstract本文主要為設計超音波振動模具以及進行反應曲面法實驗,分析超音波振動輔助沖切加工問題,本文設計單行程超音波振動沖切模,分析與量測軸向超音波振動最大振幅與頻率並固定其參數,再分別探討不同模具間隙、剪切角度與沖壓速度對沖切加工時沖頭負載及斷面形狀之效應。結果顯示,加載超音波振動時,間隙與沖壓速度對於改善毛邊垂直高度皆有良好的效應。 zh_TW
dc.description.abstractThe paper employs experiment to analysis the trimming problems with ultrasonic vibration. First the result of design Single metal vibration trimming and blanking model to trim the metal. The different clearance, cutting angle, trimming speed are discussed separately to know the effect of punch load and edge profile in trimming process with vibration punch. The result reveals that ultrasonic vibration can decrease the punch load and improve the quality of edge profile by increasing the cutting angle and appropriate clearance and trimming speed. en_US
