Sheet Metal Flange Height

A 1 degree tolerance on all bend angles.

Sheet metal flange height.

Determine your minimum bend by measuring the distance from your closest feature i e. The minumum flange length is based on the die used to bend. However for typical parts meant to be cost effective and easily produced the following tips should be useful. Design for manufacturability sheet metal guidelines bends for the ease of manufacturing multiple bends on the same plane should occur in the same direction.

Height of curved flange min. Choose a bend radius that matches your minimum bend. It shall be equal to three times of sheet thickness plus bend radius. The minimum distance between two counterbores is eight times the material thickness.

Thick ness min bend radii. 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. Metal thickness 2024 0 aluminum formed before heat treatment. 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.

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. Thick ness min bend radii min. We are here to help. Avoid large sheet metal parts with small bent flanges.

Minimum sheet metal flange bend length is required to avoid cracks in the bending area. Step processing method some of the lower profile sheet metal z shaped steps are bent and the processing manufacturers often use simple molds to machine on punch presses or. Bends in sheet metal are manufactured using sheet metal brakes. When designing parts for laser cutting one should not make holes smaller than the thickness of the material.

Height of curved flange min. Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. Avoid large sheet metal parts with small bent flanges. Relief height is generally kept greater than two times of sheet thickness plus bend radius.

In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm. Offsets are used to create z shaped profiles in sheet metal parts. A cutout or the edge of your flange to your bend. Mild sheet metal low carbon monel sheets annealed.

If you have any questions or want to discuss your design contact us. We offset height tolerance at 0 012 in. 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.
