There are standard charts available with sheet metal design handbook for calculating k factor ideally it should be 0 5.
Calculating potential metal sheet.
You can calculate sheet metals more easily with calculation of the sheet metals you use in project.
Procedure is as below.
Use k factor calculator to calculate k factor values.
So if you got k factor value now you can easily calculate bending allowance.
Enter k factor values.
Here are the steps to be followed to calculate sheet metal flat length.
Enter flange length internal radius and thickness values.
Select the metal type you are working with from the drop down menu for example aluminum 6063 or brass.
Type in the number of pieces you are purchasing.
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.
You can easily calculate by entering sheet metal dimensions without any restrictions.
Keep default values in calculator as zero.
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.
After the calculation you can see total weight in the calculations section.
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.
