Keep default values in calculator as zero.
Calculating potential metal sheet.
Type in the number of pieces you are purchasing.
You can calculate sheet metals more easily with calculation of the sheet metals you use in project.
You can easily calculate by entering sheet metal dimensions without any restrictions.
Zn s 2 ag aq 2 ag s zn 2 aq e 1 100 v.
Select the metal type you are working with from the drop down menu for example aluminum 6063 or brass.
Ultimate tensile strength psi.
Enter k factor values.
Enter flange length internal radius and thickness values.
But the most accurate way to find out k factor is reverse engineering of a small but same sheet metal sample piece.
Value of bend deduction and flat pattern are shown in result section.
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.
Choose the shape of the piece from the drop down menu.
So if you got k factor value now you can easily calculate bending allowance.
Use k factor calculator to calculate k factor values.
There are standard charts available with sheet metal design handbook for calculating k factor ideally it should be 0 5.
Here are the steps to be followed to calculate sheet metal flat length.
