Rolling Steel Plate Calculations?

Use your 3D cad program. Your company's bend tables.

machinery's handbook has bend calculations.

I'm out on the road or Id give you page number...

The machinery's handbook calculations assumes that the tooling used is correct.

I worked at a place where they were using the dies for a different brake. When they bought the correct dies the tonnage needed to bend parts went down.

That's why I mentioned the company's bend tables. The actual results may not coincide with the theoretical results.

But it is a good place to start.

Thanks for that. I've been travelling and off line for a bit.

the cut length of a plate to roll is to the centerline of the material. The method is:

ID + material thickness x pi = length to cut for rolling to that exact ID

Low tech tools are easiest to understand and use. In high school the drafting course taught us how to do this. I would suggest going to a library and looking up the 'old school' way of drafting.

Once you can do this manually on paper, doing it with a 2D software program like a basic AutoCAD program is quite easy.

Learn how to do it yourself and you will never have to ask for help again.
