  2. In this thesis it was proposed to simulate the drawing, trimming, flanging by using error - adjustment method. the initial trimming lines would be adjusted and optimized in the computer by adjusting error. if the shape error between the flanging boundary line and the target is larger than prescribed, the redundant area is subtracted from the initial blank by some amount of volume along the deformation path, and the insufficient volumes are added to the initial blank by the same amount

    本文提出,利用基於變形路徑的誤差修法( error - adjustment ) ,結合cae技術將對初始修邊線的調試過程在計算機中進行模擬(包括拉延、修邊、翻邊、整形等)計算,通過控制翻邊后零件成型邊界與實際目輪廓之間的寸誤差來優化修邊線,如果初始邊、翻邊后的輪廓與目體的邊界存在較大偏差,則初始邊輪廓中多餘部分單元將沿其變形路徑以相同體積量被除,不足部分則沿其變形路徑以相同體積進行補償。
