Stainless steel sheet metal bend radius chart.

The following tables showing the minimum bend radius allowable in air bending process for aluminum and steel or stainless steel. Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. A general guideline the minimum metal bend radius is approximately equal to the material thickness.

The opposite happens with stainless steel the required force is 1 7x higher than the ones displayed in this table. Microform precision llc 4244 south market court suite a sacramento ca 95834 phone. The gauge inside radius die opening and minimum flange length are all interconnected through different equations and relationships the air bend force. Divide 50 by the material s reduction percentage as specified by the material supplier subtract by 1 and then multiply by the plate thickness.

Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. The minimum bend radius data shown in these charts is measured to the inside of the bend. The material thickness will be measured in decimal form not by the gauge number.

Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal. You described a rough rule to find a steel s minimum bend radius. In a previous bending basics article you mention a material s tensile reduction percentage used for calculating the minimum inside bend radius of various metals. 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 tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. Table 1 preferred recommended 90 degree bend radii for various sheet metals. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. 22 gauge 0 030 0 76 mm 0 5 12 7mm.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. Bottoming as the name bottom pressing suggests the punch presses the metal sheet onto the surface of the die so the die s angle determines the final angle of the workpiece.
