Bend Table Sheet Metal

Geometry of tooling imposes a minimum bend dimension.

Bend table sheet metal.

Exemple 1 for metal sheet bending tables. A section view of a typical punch and die set used to create sheet metal bends. A sample bend table for sheet metal operations is provided in install dir lang english sheetmetal bend tables sample btl. To use the tables below.

Each column specifies a bend radius. You can generate flat patterns by unfolding sheet metal features using a uniformly applied. Understanding the bend deduction and consequently the bend allowance of a part is a crucial first step to understanding how sheet metal parts are fabricated. Since gauge tables were introduced all the parameters can be controlled base on the drop down selection which makes life much easier.

All bend table types bend deduction bend allowance and k factor. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. 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.

Bend allowance mild sheet steel 90 degree bend allowance bend allowance chart example flat size 2 2 095 3 905. To create your own bend table copy and edit this bend table with any text editor. The second important number when creating sheet metal designs is the bend radius value. A bend table is a table of bend deductions arranged in rows and columns.

Sheet metal bend radius. Each row in a bend table specifies a bend angle. 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. Refer to table s for your choice of material.

Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. 0 060 crs 2 000 2 000 r0 031 aluminum 90 deg. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

Bend tables created as a text file support the following. When unfolding if a bend radius or angle does not correspond to a specific entry a process interpolates between adjacent values in the table. The problem with a solidworks sheet metal bend table is that it can only control the bend allowance bend deduction or k factor but the thickness and radius is still free to be changed manually.
