Bend Radius Sheet Metal Stainless Steel Metric

Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.

Bend radius sheet metal stainless steel metric.

Microform precision llc 4244 south market court suite a sacramento ca 95834 phone. 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. The bend allowance added to the flange lengths is equal to the total flat length of the part.

The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. Table 1 preferred recommended 90 degree bend radii for various sheet metals. Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried.

Therefore the bend deduction equals the difference between the mold line lengths and the total flat length. As this happens you gain a small amount of total length in your part. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. Divide 50 by the material s reduction percentage as specified by the material supplier subtract by 1 and then multiply by the plate thickness.

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. Making a custom metal form using sheet metal is a surprisingly delicate process. 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.

22 gauge 0 030 0 76 mm 0 5 12 7mm. To get the best results a design engineer has to account for many factors such as the end use of the metal form the material the sheet metal is made of plain steel stainless steel etc and the dimensions shape of the final product. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. Category thickness minimum bend bend radius.

We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. Understanding the bend allowance and consequently the bend deduction of a part is a crucial first step to understanding how sheet metal parts are fabricated. The bend deduction sometimes called the bend compensation describes how much the outside of the sheet has been stretched. 22 gauge 0 030 0 76 mm.
