5 Sheet Metal Design Tips for Easy Manufacturing Bright

The sheet metal design rule of thumb in this case is: The distance between the sheet metal bend line and edge of the hole should be two times or greater the thickness of the sheet metal. Minimum Sheet Metal Bending Radius: Minimum sheet metal bend radius depends on the selection of tool and the process. The more ductile the sheet metal, the

Tips for Bending Sheet Metal Make It From Metal

Sheet metal is extremely handy for all kinds of jobs since it’s so easy to work with. You can do a lot with only a handful of tools. Even still, it can be pretty easy to mangle if you don’t use the right technique. Here are a few tips that will let you make accurate, clean, and professional-looking bends when you’re working with sheet metal.

Sheet metal fabrication basics: 7 strategies for punching

1. Communicate Forming Variables. Walk into a fab shop and you’ll likely see technicians working with CAD. They’re transforming a drawing into a part that can actually be made out of sheet metal. A big part of this is taking into account bend radii. Just as bends made on the press brake require radii, so do forms on the punch press.

The Basics of Bending Sheet Metal Xometry

Bend Orientation Rules. Another important consideration when designing sheet metal parts is bend orientation. Bends originating from the same plane should be oriented in the same direction to avoid the need of reorienting the part. This will save both money and time. Keeping a consistent bend radius across all bends will also make designs more
