Bend Radius Sheet Metal Rule Thumb

Dropping below that value can bring problems your way.

Bend radius sheet metal rule thumb.

The sheet metal design rule of thumb in this case is. 2 5 material thickness bend radius. 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. What could be simpler than choosing the inner radius ir just the same as the material thickness.

The sheet metal design rule of thumb in this case is. So in this case the minimum inside bend radius is 2 times the material thickness. 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.

Now multiply that answer by the plate thickness. This avoids later troubles overthinking and silly mistakes. 5 1 4. Rule of thumb for minimum bend radius.

The minimum bend radius for mild steel sheet metal. Minimum sheet metal bending radius. Determine your minimum bend by measuring the distance from your closest feature i e. Next subtract 1 from that answer.

The more ductile the sheet metal the smaller the inner bend radius is possible. Note that this is just a rule of thumb. Outside radius of curls must be at least twice the sheet s thickness. Bends should be at least six times the material s thickness plus the radius of the curl.

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. Choose a bend radius that matches your minimum bend. Minimum sheet metal bend radius depends on the selection of tool and the process. Larger radius will just make some other calculations a little more difficult.

A cutout or the edge of your flange to your bend. If the material is 0 5 in. 4 0 5 2.
