Bend Radius Sheet Metal Stainless Steel Metric

As this happens you gain a small amount of total length in your part.

Bend radius sheet metal stainless steel metric.

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 radii listed are standard minimum if manufacturing for aircraft and aerospace applications. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. 22 gauge 0 030 0 76 mm.

22 gauge 0 030 0 76 mm 0 5 12 7mm. Therefore the bend deduction equals the difference between the mold line lengths and the total flat length. The bend allowance added to the flange lengths is equal to the total flat length of the part. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.

Divide 50 by the material s reduction percentage as specified by the material supplier subtract by 1 and then multiply by the plate thickness. The bend deduction sometimes called the bend compensation describes how much the outside of the sheet has been stretched. Table 1 preferred recommended 90 degree bend radii for various sheet metals. Recommended minimum bend radii for steel and aluminum.

You described a rough rule to find a steel s minimum bend radius. 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. Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.

The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. Microform precision llc 4244 south market court suite a sacramento ca 95834 phone. 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. Making a custom metal form using sheet metal is a surprisingly delicate process.

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. Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried. 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.
