Fabrication Formulas

Bending Sheet Metal FormulasFormulas:

BA = {\dfrac{\pi}{180} \cdot B< \cdot (IR + K \cdot MT)}

 

BD = {2*(\tan \left( \dfrac{B<}{2}\right) \cdot (IR + MT))-{\dfrac{\pi}{180} \cdot B< \cdot (IR + K \cdot MT)}}

 

K={\dfrac{180 \cdot BA}{\pi \cdot B< \cdot MT}-\dfrac{IR}{MT}}

 

OSSB = {\tan \left( \dfrac{B<}{2}\right) \cdot (IR + MT)}

 

ISSB = {\tan \left( \dfrac{B<}{2}\right) \cdot IR }

 

OSOS={\dfrac{IR+MT}{\tan{\left( \dfrac{B<}{2} \right)}}-(IR+MT)}

 

ISOS={\sin\left(\dfrac{B<}{2}\right) \cdot \left(\sqrt{2 \cdot ISSB^2}-IR \right)}

 

ISTM={\tan{\left(\dfrac{B<}{2}\right)} \cdot MT}

 

ISS={ISTM-ISOS}
