Bend Table Sheet Metal

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.

Bend table sheet metal.

We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. A section view of a typical punch and die set used to create sheet metal bends. When unfolding if a bend radius or angle does not correspond to a specific entry a process interpolates between adjacent values in the table. Sheet metal bend radius.

All bend table types bend deduction bend allowance and k factor. Since gauge tables were introduced all the parameters can be controlled base on the drop down selection which makes life much easier. A sample bend table for sheet metal operations is provided in install dir lang english sheetmetal bend tables sample btl. 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.

Bend allowance mild sheet steel 90 degree bend allowance bend allowance chart example flat size 2 2 095 3 905. Exemple 1 for metal sheet bending tables. Refer to table s for your choice of material. To create your own bend table copy and edit this bend table with any text editor.

Each row in a bend table specifies a bend angle. To use the tables below. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. Refer to the chart for values for folder as well as various press brake tooling combinations.

Each column specifies a bend radius. The diagram shows one such mechanism. A bend table is a table of bend deductions arranged in rows and columns. The second important number when creating sheet metal designs is the bend radius value.

0 060 crs 2 000 2 000 r0 031 aluminum 90 deg. 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. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. You can generate flat patterns by unfolding sheet metal features using a uniformly applied.

Geometry of tooling imposes a minimum bend dimension. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched.
