After completing this chapter, you will be able to perform the following: – Start the Autodesk Inventor sheet metal environment – Modify settings for sheet metal design – Create sheet metal parts – Modify sheet metal parts to match design requirements – Create sheet metal flat patterns – Create drawing views of sheet metal parts Chapter 10 - Objectives
Sheet Metal Fabrication Sheet Metal Examples –Enclosures –Brackets –Structures or Frames
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 the bend. This intersection is used when the angle of the bend is less than or equal to 90 degrees.
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 tangent to the outer surface of the bend. The same formula is used to determine the unfolded length of the part.
Sheet Metal Parts Sheet Metal Design Methods –Folded State –Flat State –Disjointed Solids –Shelled Parts
Sheet Metal Parts Sheet Metal Part Template(s) Convert part to Sheet Metal part –Model tab –or Environment tab
Sheet Metal Tools Sheet Metal Rules –Click the Sheet Metal tab > Setup panel –Sheet metal specific parameters driven by rules
Sheet Metal Tools Flat Pattern –Represents the starting point for sheet metal part manufacturing –Creates a 3D model of the unfolded part Displayed in a 2D drawing view Flat Pattern – Browser Flat Pattern – Extents, area
Sheet Metal Tools Flat Pattern –Extents, area –Edit Definition Punch Representation –Flat Patten Features Effect Flat Pattern Only
Sheet Metal Tools Common Tools – Sheet Metal tab –Holes –Work Features –Feature Patterns –Mirror –Parameters
Detailing Sheet Metal Designs –3D Model and Flat Patterns
Checking Your Skills 1.The base feature of a sheet metal part is most often a: a.Revolve b.Face c.Extrude d.Flange 2.What is the correct procedure to change the edges connected by a bend feature? a.Suppress the existing bend, and add a new bend. b.Delete the existing bend, and add a new bend. c.Edit the bend, and select the new edges. d.Create a corner seam between the desired faces. 3.Which command would you use to create a full-length rectangular face off of an existing face edge? a.Flange b.Extrude c.Face d.Bend 4.What action is required to update a flat pattern model? a.Right-click on the flat pattern in the browser, and select Update. b.Erase the existing flat pattern, and recreate it. c.Create a new flat pattern drawing view. d.The flat pattern is updated automatically. Continued….
Checking Your Skills - continued 5.True__ False__ Sheet metal parts can contain features created with Autodesk Inventor modeling tools. 6.True__ False__ Sheet Metal Style settings cannot be overridden; a new style must be created for different settings. 7.True__ False__ During the creation of a sheet metal face, the face can extend to meet another face and connect to it with a bend. 8.True__ False__ 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.True__ False__ When creating a sheet metal punch, you can select an alternate 2D representation to display in flat patterns and drawing views.
