Bend Radius Sheet Metal Stainless Steel Metric

It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

Bend radius sheet metal stainless steel metric.

Divide 50 by the material s reduction percentage as specified by the material supplier subtract by 1 and then multiply by the plate thickness. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. 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.

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

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. Discover all our calculation tools in the calculators section of the top menu. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. Making a custom metal form using sheet metal is a surprisingly delicate process.

As this happens you gain a small amount of total length in your part. 22 gauge 0 030 0 76 mm. 22 gauge 0 030 0 76 mm 0 5 12 7mm. The bend allowance added to the flange lengths is equal to the total flat length of the part.

Therefore the bend deduction equals the difference between the mold line lengths and the total flat length. Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t. Microform precision llc 4244 south market court suite a sacramento ca 95834 phone. The minimum bend radius data shown in these charts is measured to the inside of the bend.

Recommended minimum bend radii for steel and aluminum. 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. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. 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.
