Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure
Odd Enclosure
Objective:
The main objective of odd enclosure design is to create an enclosure using solid body to sheet metal using sheet metal commands.
Introduction:
Enclosure is a cavity of a body which surrounds the component by providing a covering for external protection and shape for the component.
Design Methodology:
Description:
To design the odd enclosure of a solid body we need few tools to design as per the input. Those tools are discussed in detail below.
1. Extrude:
Extrude is used to create a solid body of the required shape and size. Here a trapezium is created using extrude command.
2. Sheet metal from solid:
Sheet metal from solid command is used to create a covering for a solid body by providing sheet metal thickness , bend radius and bend factor.
3. Flange:
Flange is used to create a sheet metal extension on the one side of the body up to required distance and angle.
4. Jog:
Jog is used to create a sheet metal bend by drawing a line and providing height and selecting the face on where to create a jog.
5. Unbend:
Unbend tool is used to create a flat sheet metal to create a hole or bead or louvre, etc,. by selecting the stationary faces or edges and then by selecting the bend faces or edges.
6. Bead:
Bead tool is used to create a projection on the sheet metal by providing a depth and radius using an open profile curve.
7. Hole:
Hole tool is used to create a simple hole or threaded hole, etc., But for the odd enclosure simple hole is created on the unbend surface with dia 10mm through the sheet metal body.
8. Rebend:
Rebend tool is used to make the unbend sheet metal to a bended one by selecting stationary faces or edges and bend faces or edges.
9. Flat pattern:
Flat pattern tool is used to create a bended sheet metal to its flat pattern by showing neutral axis at where the sheet metal to be bended and at what angle to be bended by selecting a base face.

Conclusion:
Odd enclosure has been designed and flat pattern view is created and viewed.
