Metric Sheet Metal Bend Radius Table

Sheet metal bend radius.

Metric sheet metal bend radius table.

The bend deduction sometimes called the bend compensation describes how much the outside of the sheet has been stretched. Each column specifies a bend radius. Cells on the right will output the desired values. When it comes to curved steel finding the precise measurements is a challenging undertaking.

With this free online tool we quickly get the sheet metal bend deduction and therefore the sheet metal blank initial flat length from the finished part measurements. Bend radii minimum bend sizes. When unfolding if a bend radius or angle does not correspond to a specific entry a process interpolates between adjacent values in the table. Specifing a bend radius from here will help prevent hair line cracks.

You can generate flat patterns by unfolding sheet metal features using a uniformly applied. 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. The bend radius of a sheet metal design will be based on the wall thickness of the part and the tooling that is available in house.

Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried. The second important number when creating sheet metal designs is the bend radius value. To solve this cmrp provides easy to use measurement calculators. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

Each row in a bend table specifies a bend angle. 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. The material thickness will be measured in decimal form not by the gauge number. 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. Use this document to choose values that are both manufacturable and meet your needs. You only have to insert interior angle flange lengths k factor inside radius and material thickness. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k.

Therefore the bend deduction equals the difference between the mold line lengths and the total flat length. A bend table is a table of bend deductions arranged in rows and columns. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. Table 1 preferred recommended 90 degree bend radii for various sheet metals.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
