請問折彎長度的問題

十年之後

請問圖上的A.B.C三處的折彎長度是按什麼計算出來的呢？謝謝!

樓主的厚料是多少啊

十年之後

<P>健哥，料厚為0.6</P>

zqvip

0.6厚的料展開系數為0.35T,樓主照這個數據算吧﹐

十年之後

還是不明白，A，B，C是點樣沖成的圓弧的數據

十年之後

A.B.C共折了三次才沖成一個圓弧的，每一次要沖多長呢？我說的是每一次要折多長。

zqvip

快上傳DWG檔﹐

yzjjlbc

<P>健哥告诉你了0.35T,没有问题!</P>

十年之後

完全明白了，原來是每一個折位在從圓弧的中點開始折的。謝謝健哥，謝謝蜗牛行路，謝謝各位來賓，謝謝我父母。<BR>

zqvip

<BR>真有意思

十年之後

每一次進步，背後總有你們這班朋友的支持和父母的支持啊，謝謝！
