Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure
Title: ADVANCED SHEET METAL NX-CAD DESIGN OF AN ODD SHAPED ENCLOSURE- CHALLENGE 5
Objective: To design an odd-shaped enclosure using sheet-metal operations in NX-CAD.
Introduction:
In this project, an odd-shaped enclosure was designed from the scratch following the basic principles and tools to perform sheet metal operations in NX 12.0. The standard thickness of the material in this project is 3 mm.
Design Methodology:
The methodology followed is as follows:
Description:
There were a lot of commands used in this challenge that are very essential. Following is the description of each command.
Tab: Tab is a command used to create a base for any sheet metal part that can be extruded from a sketch. The sketching plane can be selected as per the designer’s choice.
Flanges: This command will allow us to select the edge of the base to create a projecting flat extruded surface. The angle, width, length, and type of flange can be determined as per the requirements.
Unbend: This command is used to unbend the sheet metal parts to create geometries and work on complicated designs. In this command, we have to select a stationary face and then select the corners of flanges to unbend.
Flat Pattern: The user chooses this command to create a flat view of the sheet metal after unbending all the sides and faces. This view can be used in drawing the flat pattern along with the bend radius and other dimensions.
Bend Table: Bend table command ensures to include all the information regarding the properties of each special feature. The properties include radius, direction, angle, etc.
Bead: The selected sketch is lifted off from the base to provide strength to the material. Similar to dimple, the material can be removed in both directions.
Hole: It can be used to make customized or standardized holes along with a defined point or path. The dept of the hole can be controlled.
Sheet metal from solid: This command is used to convert the solid body into a sheet metal body. After selecting the command and the solid body, we can also remove the edge sharpness by removing the material at these places.
Jog: Jog is a command to lift off one whole side of the part. By selecting a line and the plane, the material can be pushed down or lifted off depending on the situation.

Conclusions:
The sheet metal design of an odd-shaped enclosure was completed using the basic commands such as Tab, Flange, Sheet Metal from solid, Jog, Hole, Unbend, Bead, Flat pattern, and Bend table. These basic commands have influenced the designer to maintain geometric constraints and achieve the final product.
