Inventor Sheet Metal Bend Table

A bend table specifies the bend allowance for a specified material thickness at specific radii and bend angles for the flat pattern analyzer.

Inventor sheet metal bend table. As this happens you gain a small amount of total length in your part. Each column specifies a bend radius. Autodesk inventor webinar series. A bend table is a table of bend deductions arranged in rows and columns.

Each row in a bend table specifies a bend angle. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. Autodesk inventor provides sample imperial and metric bend tables as spreadsheet files. Set up externally stored bend table using excel.

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. 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. Tolerances determines if a parameter in the part model is valid. Autodesk inventor webinar series.

You can generate flat patterns by unfolding sheet metal features using a uniformly applied. Units of measure default is centimeters. T1 represents the default sheet metal thickness specified in the sheet metal styles dialog box. Bend tables for sheet metal materials.

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. When unfolding if a bend radius or angle does not correspond to a specific entry a process interpolates between adjacent values in the table. Share and vote on ideas for future product releases. Double click a bend table.

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.
