Odd Box enclosure Using NX

OBJECTIVE

• Modelling of odd box enclosure in nx cad.
• Applying flat pattern to the model.

INTRODUCTION:

Sheet metal is metal formed by an industrial process into thin, flat pieces. Sheet metal is one of the fundamental forms used in metalworking, and it can be cut and bent into a variety of shapes.

Countless everyday objects are fabricated from sheet metal. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate steel or "structural steel".

Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter.

The sheet metal application provides an environment for the sheet metals used in Machinery, Automotive, Aerospace etc.

We can develop enclosures, brackets and other parts by brake press.

Convert to Sheetmetal is used to convert the null body or any part imported into sheet metal.

Design Methodology:

1. Creating A Solid body
2. Wrapping the solid body in the sheet metal
3. Adding flange and Jog
4. Unbending and adding beads and holes
5. Rebend
6. Appling Flat pattern

Description of tools used.

Extrude: Used to create a solid body with a given width and direction.

Sheet metal from solid: It is used to create the sheet metal from the solid body by selecting the faces and edges.

Flange: Used to create the flanges of required length and the angle and bend radius.

Jog Used to create the flange by lifting the material.

Unbend: Used to flatten the sheet metal on give base surface.

Bead: It is used to create a stamping effect inside or to outside of the sheet metal.

Hole: It creates a hole of required dia on the selection of the location of the point.

Rebend: It is used to get the sheet metal to its original shape after bending it.

Flat-Pattern: It is used to create a flat surface on the selection of base surface which can be used for the drawings.
