forces required to bend tubing
forces required to bend tubing
(OP)
I'm looking for information and descriptions of the maths for calculating the forces required to permanantly bend tubing using a fixed die and rolling wiper. Anyone have any suggestions for this metallurgist who's a bit out of his element?
I can post a schematic of the machine in a bit if that will help.

trying to find some formula's you can use to estimate bending and will post later

Couldn't find specific formula for tube bending but found this for sheet metal bending which is different:-

what you need to do is find the plastic bending moment formula for the tube in question from which you can estimate the force required to bend the tube.
