Sheet Metal Calculators

This is all easily gotten BY SEARCHING!

Try it next time.

I'll just add that if you have never done (fabricated) this before, you should personally talk to a local professional fabricator for a quote, or at least some current cost direction. It drives me insane when engineers I know and work with try to estimate costs with poor results, because they told a client what to expect. I think I'll go cut my own hair now.

I think it's obvious OP's never done this before.

I think it's obvious the OP thinks he can get a reliable cost estimate by plugging a few numbers into a spreadsheet.

likely off the topic ... just seek it out for personal interest

K-factor

As a pc of sheet or plate is bent the inside radius material compresses and the outside material stretches. Somewhere in between these two there is a neutral line where the grains of metal neither compress nor stretch.

The distance from the sheet metal surface to this line is the K-factor.

The K-factor is a decimal number that when multiplied by the overall sheetmetal thickness it will give you the distance to the neutral line from the metals surface.

Example: 18gauge material with a K-factor of .313

18 ga = .049"

.049 x .313 = .0153"

So from the surface that will be the inside radius, to the neutral line it is .0153"

It is along this neutral line that you can calculate the needed material to make the bend with.

K-factors are not always hard & fast as it depends a lot on the type and hardness or your material. This can vary even with different lots of the same material.

There, that's my two cents worth.

Hi,

sheet metal fabrication generally consists of a few basic manufacturing processes namely, cutting a blank to size, brake forming, welding, grinding, deburring and finishing (whether it be chemical coating or painting. With Costimator, cost estimating software for manufacturing, it is very easy to develop a master routing template, saving enormous time for all estimators in not having to re-produce a routing every time a similar welding quote is required.
