Bending Aluminum Sheet Metal

Likewise when you are trying to develop a flat pattern you will have to make a deduction from your desired part size to get the correct flat size.

Bending aluminum sheet metal.

That s the ideal anyway but the reality is that many parts arrive at the press brake in a less than ideal state. Then use your bend allowance to draw your second bend line the intervening distance between your bend lines bend radius. From a bending perspective it s always best to bend these parts in an annealed state and then temper them to the correct condition. In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend.

If you re bending 0 020 thick material use a 0 020 radius. Depending on designation alloys go through different heat treatment procedures during production. A cutout or the edge of your flange to your bend. Make sure the bar is seated firmly inside the frame.

Bending is one of the most common sheet metal fabrication operations.

As this happens you gain a small amount of total length in your part. Choose a bend radius that matches your minimum bend.
