Inventor Sheet Metal Bend Table

Autodesk inventor provides sample imperial and metric bend tables as spreadsheet files.

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. 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. You can generate flat patterns by unfolding sheet metal features using a uniformly applied. Share and vote on ideas for future product releases.

Each column specifies a bend radius. Units of measure default is centimeters. Autodesk inventor webinar series. 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.

Tolerances determines if a parameter in the part model is valid. Each row in a bend table specifies a bend angle. 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. Set up externally stored bend table using excel.

Bend tables for sheet metal materials. The table arranges bend deductions in rows and columns. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. Autodesk inventor webinar series.

T1 represents the default sheet metal thickness specified in the sheet metal styles dialog box. Double click a bend table. 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. As this happens you gain a small amount of total length in your part.

When unfolding if a bend radius or angle does not correspond to a specific entry a process interpolates between adjacent values in the table. Browse to the autodesk inventor version design data bend tables folder.
