Bending-Sheet Metal-Tolerance

[jesseg010]

ok so maybe a {NOOB} question but okay.

depending on type of metal (examples below) is their a standard or a great reference (for tolerance change) to keep by my side when thickness and number of bends change? for example taken into account thin material allowing for spring back, or thicker hot rolled material. Please get back to me if my question wasnt clear. this would mean a great deal to me thanks again.
