I know this is not exactly CNC topic, but I don't know where else to ask, so, what I need is data on minimal bending radius for standard European steel shapes, like HEA, HEB, UNP, angular, and pipes, for 90 degrees and other angles, I think this is actually depending on ethnology and machines for bending, but I would appreciate any data on this, I couldn't find any data by googling,
thanks
