Sheet Metal Fabrication Bend Tables

L=A+B-x Construction L Unfolded Length A Length of folded face 1 B Length of folded face 2

x Adjustment from bend table

Measurements A and B are to the intersection of

the extended outer faces on either side of thebend. This intersection is used when the angle

of the bend is less than or equal to 90 degrees.


5/37

Sheet Metal Fabrication Bend Tables

L=A+B-x Construction L Unfolded Length A Length of folded face 1 B Length of folded face 2 x Adjustment from bend table

Use these measurements when the bend angle is greater than 90

degrees. The measurements are parallel to the face, and tangentto the outer surface of the bend. The same formula is used todetermine the unfolded length of the part.

Checking Your Skills1. The base feature of a sheet metal part is most often a:

1. Revolve

2. Face

3. Extrude

4. Flange

2. What is the correct procedure to change the edges connected by a bend feature?1. Suppress the existing bend, and add a new bend.

2. Delete the existing bend, and add a new bend.

3. Edit the bend, and select the new edges.

4. Create a corner seam between the desired faces.

3. Which tool would you use to create a full-length rectangular face off of an existing face edge?

1. Flange

2. Extrude

3. Face

4. Bend4. What action is required to update a flat pattern model?

1. Right-click on the flat pattern in the browser, and select Update.

2. Erase the existing flat pattern, and recreate it.

3. Create a new flat pattern drawing view.

4. The flat pattern is updated automatically.

5. Sheet metal parts can contain features created with Autodesk Inventor modeling tools.

6. Sheet Metal Style settings cannot be overridden; a new style must be created for different settings.

7. During the creation of a sheet metal face, the face can extend to meet another face and connect to it with a bend.

8. A sheet metal cut that used the Distance extents option must be created equal to the Thickness parameter.9. What is a common term for a three-bend intersection?

10. When creating a sheet metal punch, you can select an alternate 2D representation to display in flat patterns and drawingviews.
