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