SW Sheet Metal Design Tutorial399

Introduction:
Sheet metal design involves creating parts or assemblies using thin sheets of metal. This tutorial will guide you through the basics of sheet metal design in SolidWorks (SW), a popular 3D CAD software.
Prerequisites:
- Basic knowledge of SolidWorks interface
- Understanding of sheet metal terminology
Creating a New Part:
1. Open a new SolidWorks part document.
2. Click the "Sheet Metal" tab in the CommandManager.
3. Select the "New Sheet Metal" command.
4. Specify the sheet metal thickness and material in the dialog box.
Creating Base Features:
- Flange: Creates a bent or folded edge on the sheet metal.
- Bend: Similar to a flange, but with a specific bend angle.
- Extrude: Creates a solid feature by extruding a sketch from the sheet metal surface.
- Hem: Creates a folded edge that wraps around an edge.
Adding Holes and Cutouts:
- Hole Wizard: Inserts various types of holes into the sheet metal.
- Extruded Cut: Creates a hole or cutout by extruding a sketch through the sheet metal.
- Slot: Inserts a slot-shaped hole or cutout.
Adding Stiffeners:
- Beaded Edge: Adds a stiffening rib along an edge.
- Hem Flange: Reinforces a bent edge by adding a hem to it.
- Rib: Creates a stiffening rib on the sheet metal surface.
Flattening the Sheet Metal:
1. Right-click on the sheet metal body and select "Flatten Body."
2. Choose the flattening method and options in the dialog box.
3. This will create a 2D representation of the sheet metal in the drawing.
Creating Bend Tables:
1. Right-click on the sheet metal body and select "Bend Table."
2. In the dialog box, specify the bend sequence, radius, and other parameters.
3. This generates a table that lists the bend information.
Importing DXF or IGES Files:
1. Open a DXF or IGES file containing the sheet metal outline.
2. Import the file into SolidWorks and convert it to sheet metal using the "Convert Entities" command.
Advanced Techniques:
- Tear Drop Features: Creates a rounded hole or cutout for easier assembly.
- Miter Joints: Creates a mitered joint between two sheet metal parts.
- Corners: Adds rounded or chamfered corners to sheet metal edges.
Conclusion:
This tutorial provides an overview of basic sheet metal design techniques in SolidWorks. By mastering these techniques, you can effectively create and manufacture a wide variety of sheet metal parts and assemblies. Remember to practice regularly and explore the advanced techniques mentioned above to enhance your skills.
