Default flatten a helical pattern

I am creating the flights for an auger that is used in feed mills.
Does anyone know the formula for laying the helix in a flat pattern.
I need to know what shape to burn on our plasma.

Thank you,

Mark

The mathematical formula for helixes can cause some aggravation if you're using a cold rolled steel or stainless.
Personally, I've had better results laying augers out by hand on AutoCAD and then importing them to my plasma program.
The only plasma program that I know of that will burn a helix on it's own is "Plate N' Sheet".
If you're unsure of how to lay out the auger send me the dimensions and I'll email you the drawing.

Can you create a flat pattern and send me the dxf file?
I can create the helical, but I can't flatten it to burn on the plasma.
I'm looking for the true flat pattern.

Helical Dimensions: (1 revolution)
O.D. 29.625
I.D. 4.625
Pitch: 24

Thank you for your help!!

I found the "Plate N Sheet" website and downloaded the eval, but it is limited.

Hi

You don't have page 320 btw? I'm dealing with this problem at the moment. Flatt bottom chute in stainless. Using Litio3D, i only get aprox right form, but need to manualy alter the results.

Would be cool to read next page to see what the book say on this :O)

Regards

I don't see why we can't see a page, but I wouldn't put up a scanned copy of the copyright book.

Thanks
