Hi
I just tried Chat GPT for this and I'm not sure if it's right...
Is there a decent and simple calculator for calculating change in wall thickness when expanding a tube? I don't think the expanding method makes a difference? If it does, then I mostly use a rolling method (same as how jewelers flatten rods) but sometimes an inner expander that pushes it larger from the inside (more risky).
I'd like a general calculator/formula so I can always able to use it, but in this specific case I'm trying to calculate it for a 27.5mm OD tube, 0.7mm wall thickness, to see if it's possible to expand it to 28.5mm OD and what the wall thickness would be if it is. GPT claims my wall thickness would be -0.3mm and since it's impossible to have a negative thickness, it's not possible to expand the tube to 28.5mm. Is this correct...?
Thanks
