Bend Radius Sheet Metal Rule Thumb

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.

Bend radius sheet metal rule thumb.

If you have any questions or want to discuss your design contact us. Now multiply that answer by the plate thickness. Larger radius will just make some other calculations a little more difficult. The minimum bend radius for mild steel sheet metal.

Dropping below that value can bring problems your way. Bends should be at least six times the material s thickness plus the radius of the curl. Rule of thumb for minimum bend radius. The sheet metal design rule of thumb in this case is.

Minimum sheet metal bend radius depends on the selection of tool and the process. The sheet metal design rule of thumb in this case is. Minimum sheet metal bending radius. If you re bending 0 020 thick material use a 0 020 radius.

Outside radius of curls must be at least twice the sheet s thickness. What could be simpler than choosing the inner radius ir just the same as the material thickness. Choose a bend radius that matches your minimum bend. Determine your minimum bend by measuring the distance from your closest feature i e.

The more ductile the sheet metal the smaller the inner bend radius is possible. 2 5 material thickness bend radius. Next subtract 1 from that answer. 5 1 4.

Here s a good rule of thumb for most materials. This avoids later troubles overthinking and silly mistakes. If the material is 0 5 in. Note that this is just a rule of thumb.

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. 4 0 5 2. 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.
