Sheet Metal Flange Height

In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm.

Sheet metal flange height.

Choose a bend radius that matches your minimum bend. Design for manufacturability sheet metal guidelines bends for the ease of manufacturing multiple bends on the same plane should occur in the same direction. A 1 degree tolerance on all bend angles. Relief height is generally kept greater than two times of sheet thickness plus bend radius.

Determine your minimum bend by measuring the distance from your closest feature i e. It shall be equal to three times of sheet thickness plus bend radius. Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm 0 03 inch whichever is larger counterbores.

Offsets are used to create z shaped profiles in sheet metal parts. Thick ness min bend radii min. Too small a flange height that is the use of a bending die is also not conducive to forming generally the height of the flange is l 3t including the wall thickness. A cutout or the edge of your flange to your bend.

When designing parts for laser cutting one should not make holes smaller than the thickness of the material. We are here to help. Height of curved flange min. Thick ness min bend radii.

Minimum sheet metal flange bend length is required to avoid cracks in the bending area. Columnist gerald davis continues a discussion of 3 d cad and precision sheet metal manufacturing in part iii of a four part series focusing on design guidelines for sheet metal. The minumum flange length is based on the die used to bend. The minimum distance between two counterbores is eight times the material thickness.

Mild sheet metal low carbon monel sheets annealed. If you have any questions or want to discuss your design contact us. Bends in sheet metal are manufactured using sheet metal brakes. Bends are the most typical feature of sheet metal parts and can be formed by a variety of methods and machines which negate the absolute need for some of the below tips.

We offset height tolerance at 0 012 in. Avoid large sheet metal parts with small bent flanges. However for typical parts meant to be cost effective and easily produced the following tips should be useful. Previous editions covered economic order quantity in batch production and the accuracy of things made from rolled sheet stock.

Metal thickness 2024 0 aluminum formed before heat treatment. 0 304mm from top of sheet to top of form and recommend an offset of 0 030 in. Height of curved flange min.
