Depending on the bending angle and radius, the material in the bend ... To think about bending a sheet of metal that has appreciable thickness, focus on an imaginary central sheet, the so-called ...

For example, consider a 20-gauge (0.036-in.) low-carbon steel sheet that must be bent 75 deg. with an inside radius of 0.093. Bend allowance is needed to determine raw material requirements.

Sheet-metal parts are known for their durability ... Another trick is to keep the bend radius consistent to keep parts more cost-effective. Thick parts tend to become inaccurate, so they should ...

After assembling a few of these pieces with some hinges, he was ready to bend some aluminum. One trick [Rupert] picked up is scoring the sheet metal on the inside of a future bend. For [Rupert ...
