Calculating Potential Metal Sheet

Value of bend deduction and flat pattern are shown in result section.

Calculating potential metal sheet.

Here are the steps to be followed to calculate sheet metal flat length. Use k factor calculator to calculate k factor values. Enter k factor values. Choose the shape of the piece from the drop down menu.

Select the metal type you are working with from the drop down menu for example aluminum 6063 or brass. Enter flange length internal radius and thickness values. Procedure is as below. Even though we had to multiply the silver reduction by a factor of 2 so that the electrons consumed would balance with those produced by the zinc oxidation we do not multiply the silver reduction potential by this factor.

Keep default values in calculator as zero. Type in the number of pieces you are purchasing. So if you got k factor value now you can easily calculate bending allowance. Ultimate tensile strength psi.

Zn s 2 ag aq 2 ag s zn 2 aq e 1 100 v. You must calculate each different shape and size separately and then add the results together by hand. There are standard charts available with sheet metal design handbook for calculating k factor ideally it should be 0 5. You can easily calculate by entering sheet metal dimensions without any restrictions.

But the most accurate way to find out k factor is reverse engineering of a small but same sheet metal sample piece.
