Inventor Sheet Metal Bend Table

Each row in a bend table specifies a bend angle.

A bend table is a table of bend deductions arranged in rows and columns. A bend table specifies the bend allowance for a specified material thickness at specific radii and bend angles for the flat pattern analyzer. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. Tolerances determines if a parameter in the part model is valid.

Share and vote on ideas for future product releases. Most sheet metal shops will produce their own bend tables by physically bending test pieces to specified angles and taking accurate measurements of the bent lengths this will allow inventor to interpolate between the discrete bend angles 20 degrees 25 degrees etc to give the most accurate result possible. Autodesk inventor webinar series. Bend tables for sheet metal materials.

To use different units enter m cm mm micron inch ft or yd for unit type. 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. As this happens you gain a small amount of total length in your part. Set up externally stored bend table using excel.

Create bend tables for sheet metal materials. Units of measure default is centimeters. When unfolding if a bend radius or angle does not correspond to a specific entry a process interpolates between adjacent values in the table. Autodesk inventor provides sample imperial and metric bend tables as spreadsheet files.

T1 represents the default sheet metal thickness specified in the sheet metal styles dialog box. The bend deduction values in the sample bend table spreadsheets are based on formula however the true value of a bend table is the ability to provide measured results from your machinery and tooling which may not be uniform across all angles and radii.
