ODD SHAPE ENCLOSURE

OBJECTIVE: To make sheet metal odd shape enclosure using Siemens NX sheet metal application.

SHEET METAL: 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.

SHEET METAL DESIGN IN CAD: Sheet metal design software considers the fabrication methods needed for manufacturing. The flat pattern can be used to document and manufacture associatively as the design changes.

DESIGN METHODOLOGY:

1.	sketch
2.	extrude
3.	sheet metal from solid
4.	add flange
5.	add jog
6.	unbend
7.	sketch and bead
8.	add holes
9.	rebend
10.	flat pattern
11.	drawing sheet
12.	odd shaped enclosure ready

DESCRIPTION:

Features used for making sheet metal for solid:

Extrude
Sheet metal from solid
Flange
Jog
Holes
Beads
Unbend
Rebend
Sketch
Flat pattern

Let us discuss the above features in detail:

Sketch: this feature is present in modelling application. It create sketch, add curves, dimensions, constraints. Used for creating sketch for tab, normal cutout, unbend.
Flange: it adds flat flange at an angle to a planar face and adds bend between the two.
Unbend: Flattens the bend and the material adjacent to it.
Sheet metal from solid: it builds a sheet metal model that takes its shape from a collection of planar faces.
Jog: it modifies the model by lifting on one side of a sketch line adding a flange between the two sides.
Holes: it just add a hole on body or part.
Rebend: it restores the previous bend feature to its original position.
Beads: lifts material along the contour of sketch that simulates the stamping tool.
Flat pattern: Creates a flat pattern feature from a formed sheet metal part.
