Bend Tables For Sheet Metal Materials

The force must exceed the material s yield strength to achieve a plastic deformation.

Bend tables for sheet metal materials.

Bending is one of the most common sheet metal fabrication operations. Material and bend table improvements. A single table lets you associate a bend allowance bend radius or k factor with any combination of thickness bend radius and material. Sheet metal gauge bend tables store properties for a designated material.

The tables below show bend radii and minimum bend sizes for materials and tooling. You can also use individual gauge tables and bend tables. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

A bend table file can contain multiple bend tables as long as the tables are for different materials or thicknesses. See sheet metal gauge table and bend table overview. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

Typically a bend table file contains a bend table for each sheet thickness that is used. About bend tables for sheet metal materials a bend table specifies the bend allowance for a specified material thickness at specific radii and bend angles for the flat pattern analyzer. Nx12 has been a well received release from sheet metal users. Since aluminum deforms differently than steel create a separate bend table file for each material type.

This is done through the application of force on a workpiece. We have a metal sheet of 3 m m thickness in iron with a hardness of 42 48kg mm2 if we go to the top of the table we see the thicknesses in brown we look at the 3 thickness of the sheet and we go down to the blue box we see a value of 240 this is in kn mm2 and if we take a 0 it will be in ton mt that is to say it will be 24ton per meter the force needed to bend in sheet of 3 m m with a v of 24 m m value in green if we follow the line. If a specific bend angle or bend radius is not in the table the flat pattern analyzer interpolates between adjacent cells to determine a value. A bend table file can contain multiple bend tables as long as the tables are for different materials or thicknesses.

Since aluminum deforms differently than steel create a separate bend table file for each material type. Aug 29 2019 community article. A great tool available to solidworks sheet metal users is the sheet metal gauge table in this table users can configure a microsoft excel spreadsheet to represent the appropriate sheet metal wall thickness based on material and gauge values. Users can also specify the available default bend radius based on available tooling.
