Bend Radius Sheet Metal Rule Thumb

Minimum sheet metal bend radius depends on the selection of tool and the process.

Bend radius sheet metal rule thumb.

Rule of thumb for minimum bend radius. A cutout or the edge of your flange to your bend. The more ductile the sheet metal the smaller the inner bend radius is possible. The sheet metal design rule of thumb in this case is.

Next subtract 1 from that answer. Note that this is just a rule of thumb. 5 1 4. If you have any questions or want to discuss your design contact us.

The inside bend radius should be equal to the thickness of the material that you re forming. So in this case the minimum inside bend radius is 2 times the material thickness. Bends should be at least six times the material s thickness plus the radius of the curl. If you re bending 0 020 thick material use a 0 020 radius.

Minimum sheet metal bending radius. 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. 2 5 material thickness bend radius. 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.

The minimum bend radius for mild steel sheet metal. Here s a good rule of thumb for most materials. Dropping below that value can bring problems your way. This avoids later troubles overthinking and silly mistakes.

What could be simpler than choosing the inner radius ir just the same as the material thickness. Larger radius will just make some other calculations a little more difficult. The sheet metal design rule of thumb in this case is. Now multiply that answer by the plate thickness.

Choose a bend radius that matches your minimum bend. Distance from outside mold line to the bottom of the cutout should be equal to the minimum flange length prescribed by the air bend force chart. If the material is 0 5 in.
