Minimum Bend Radius Sheet Metal Metric

So if the metal plate is 75 thick you would multiply 4 x 75 3 so your minimum inside bend radius would be roughly 3 times the thickness of the material in this case or 2 25.

Minimum bend radius sheet metal metric.

Use this document to choose values that are both manufacturable and meet your needs. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. For hems a bend of 180 degrees it s highly desirable to use at least one material thickness for most alloys in this size range and essential for aluminum. Sheet metal bend radii.

Minimum sheet metal flange bend length 3 x sheet thickness bend radius minimum hole diameter guidelines. Minimum bend includes minimum closeness of cutout to bend radius cold rolled steel 14 gauge 0 075 1 91mm. Minimum bend radii the minimum bend radius data shown in these charts is measured to the inside of the bend. If these guidelines are not followed more research and or some form of analysis may be requried.

It shall be equal to three times of sheet thickness plus bend radius. Steel american iron and steel institute. Minimum sheet metal flange bend length is required to avoid cracks in the bending area. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.

Discover all our calculation tools in the calculators section of the top menu. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer. Since commercial sheet metal bending can be done with less concern for stresses caused during forming.

For thin gauges 063 and less 1 2 the material thickness for simple bends of 90 degrees or less is acceptable. An air bend force chart or force chart breaks down a number of key components of sheet metal bending in an easy to reference format. The gauge inside radius die opening and minimum flange length are all interconnected through different equations and relationships the air bend force. Bend radii minimum bend sizes.

Preferred recommended 90 degree bend radii for various sheet metals.
