Mild Steel Sheet Metal Bend Radius Chart

Refer to table s for your choice of material.

Mild steel sheet metal bend radius chart.

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 deduction is 1 8 times the steel plate thickness and 1 6 times the aluminum plate. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. If the material is 0 5 in.

The gauge inside radius die opening and minimum flange length are all interconnected through different equations and relationships the air bend force. To use the tables below. The material thickness will be measured in decimal form not by the gauge number. Material bend radii and minimum bend size charts please note.

Microform precision llc 4244 south market court suite a sacramento ca 95834 phone. To keep it simple i also use a 2 mm inside radius. None 90 bend unfold according to the neutral layer the distance from neutral to sheet inner side is t 3 inner r can refer to the above chart. V die width is 6 8 times the plate thickness.

The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. The minimum bend radius data shown in these charts is measured to the inside of the bend. Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer. This tool allows you to determine tonnage internal radius v die opening and minimum flange you just have to insert the characteristics of the sheet metal to be bent.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. Now multiply that answer by the plate thickness. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance.

Discover all our calculation tools in the calculators section of the top menu. None 90 bend 180 angle 90 deduction. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. So in this case the minimum inside bend radius is 2 times the material thickness.

The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. Finding the true minimum bend radius for steel or aluminum plate requires a little research. I can now see that the minimum flange length is 8 5 mm for such a bend so i have to keep it in mind when designing. The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius.
