Bend Radius Sheet Metal Rule Thumb

4 0 5 2.

Bend radius sheet metal rule thumb.

Now multiply that answer by the plate thickness. Outside radius of curls must be at least twice the sheet s thickness. A cutout or the edge of your flange to your bend. If you re bending 0 020 thick material use a 0 020 radius.

Minimum sheet metal bending radius. 2 5 material thickness bend radius. Determine your minimum bend by measuring the distance from your closest feature i e. Dropping below that value can bring problems your way.

5 1 4. The inside bend radius should be equal to the thickness of the material that you re forming. 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. 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. Note that this is just a rule of thumb. Bends should be at least six times the material s thickness plus the radius of the curl.

Choose a bend radius that matches your minimum bend. The sheet metal design rule of thumb in this case is. If you have any questions or want to discuss your design contact us. Minimum sheet metal bend radius depends on the selection of tool and the process.

The minimum bend radius for mild steel sheet metal. Rule of thumb for minimum 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. Larger radius will just make some other calculations a little more difficult.

Here s a good rule of thumb for most materials. So in this case the minimum inside bend radius is 2 times the material thickness. This avoids later troubles overthinking and silly mistakes.
