Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure

Odd Shaped Sheet Metal Enclosure Design Workflow using Siemens NX

Objective

The aim of this project is to design workflow to create enclosures with odd shapes and angles using Siemens NX Sheet Metal Application

DESIGN METHODOLGY

DESCRIPTION

• NX Sheet Metal Application has some advanced features that allows to convert a solid body created through NX Modeling to Sheet Metal Parts. These features create sheet metal by generic solid body by ripping the edges cleaning up the geometry and converting the sheet metal body.
• This reports walks through steps involved in creation of odd shape sheet metal enclosure through NX Solid Body

Solid Body Creation

The first phase is to create a new Solid Model through NX Modeling features. A 2D sketch is created in XY Plane and Extruded to desired Length.

Convert to Sheet Metal

• The Next step is to wrap the solid body with sheet metal. The Sheet metal model is created by takings its shape from the collection of planar faces.
• The Thickness, bend parameters were defined and bend edges are selected and the Sheet Metal Model is formed.

Sheet Metal features

• After creating SM from the Solid Model some of the sheet metal features are created namely Flanges, Jog.
• A Jog Sketch Profile is created and the material is deformed based on the properties like Height, Reference and Inset type.

Unbend & Rebend SM

• The Next step is to Unbend the Sheet Metal and add some more features like Beads and Holes.
• The fact that these features are added after unbend operation is to have a nice bead profile throughout the bend and unbend regions of the Sheet Metal.
• A Simple hole is also added with direction of the hole normal to the face of the SM
• After this the sheet metal is rebend that restores to its previous bent state with the added features.

Creating Flat Pattern

• The Final step is to create a Flat Pattern by defining the upward face and Orientation Method .
• Finally the default call out preferences were modified in sheet metal preferences option and the file is exported to Drawing sheet.

Some of the Model views are attached below,

CONCLUSION

Thus Sheet Metal model is created through conversion of solid model and some of the odd shapes and angles were created and understood its features
