Chapter 9Sheet Metal Design

• After completing this chapter, you will be able to

• 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 a sheet metal part

• Sheet Metal Uses

• Enclosures

• Brackets

• Structures or Frames

• 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.

• 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 Design Methods

• Folded State

• Flat State

• Disjointed Solids

• Shelled Parts

• Sheet Metal Part Template(s)

• Sheet Metal Environment

• Sheet Metal Styles

• Stores sheet metal specific parameters of a part

• Multiple sheet metal styles can be included

• Sheet Metal Styles

• Bend Tab

• None

• Intersection

• Straight Line

• Arc

• Sheet Metal Styles

• Corner Tab

• Round

• Square

• Tear

• Trim to Bend

• Sheet Metal Face

• Extrudes a closed profile a distance equal to the sheet metal thickness

• Unfold Options

• Relief Options

• Contour Flange

• Created from an open sketch profile

• Bends are added at sharp intersections

• Flange

• Creates a sheet metal face and bend to an existing face

• Extends the full length of the selected edge

• Creating Sheet Metal Parts

• Hem

• Eliminate sharp edges

• Strengthen an open edge of a face

• Material is folded back over a face with a small gap

• Single

• Double

• Teardrop

• Rolled

• Creating Hems

• Fold

• Turns a flat pattern into a folded model

• Add folds at sketched lines

• Bend

• Child objects of other features

• When two faced connect

• Connect disjointed face

• Modifying Sheet Metal Parts

• Cut

• Sheet Metal implementation of Extrude > Cut

• Distance of the cut is equal to the Thickness parameter

• Project Flat Pattern

• Cut Across Bend

• Cut Across Bend

• Corner Seam

• Created when three faces meet

• Create mitered gaps between coplanar faces

• Corner Round

• Sheet Metal specific Fillet tool

• Corner Chamfer

– Sheet Metal specific Chamfer tool

• PunchTool

• Creates Cuts and 3D Deformations

• Dimples

• Louvers

• Punch Folder

• Applications Options > iFeature tab

• Punch Tool

• 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

• Common Tools

• Work Features, Holes, Catalog Tools, Mirror and Feature Patterns, Promote, Derived Component, Parameters, Create iMate

• Similar to the part environment

• Detailing Sheet Metal Designs

• 3D Model and Flat Patterns

• Documenting Sheet Metal Designs

• Skill Exercise 9-1
