1. Title : Advance Sheet metal design with NX CAD - 7_ Metal bracket-II

2.Objective:

To design the sheet metal casing as per dimensions provided in the master sketch with the help of Seimens NX CAD software

3. Introduction :

The material which posses properties to get formed into thin sheet are called as sheet metals.
Sheet metal have uniform thickness and Thickness ranges from 0.15mm to 6mm, below 0.15mm is called as foil and above 6mm is called as plates.

Applications include :

Aircraft bodies
Automobiles
Utensils used for domestic purpose
Beverage cans

Create a metal bracket using the NX CAD sheet metal Design workbench.

4. Design methodology / approach:

Setting preferences for Sheet Metal
Create sketch
Create Flanges
Normal cutout
Break corner
Unbending
Add Hole
Advance Flange
Rebend
Add Gusset

5. Description- Features used:

Sketch: To make a sketch select a plane according to perspectives and views.

Contour Flange: The contour flange is a flange created using the open sketch created ina plane. Can have any profile or at any angle.

NORMAL CUT-OUT: A sketch is drawn on respective plane or face to remove unnecessary material.

Break Corner: Provide fillets to the sharp corners.

UNBEND: Used to unbend the surfaces with respective to the selected face.

HOLE: Create holes in the sheet metal at specified position and diameter.

Rebend: Create the rebend operation at all flanges.

Advanced Flange: Used to create flanges from edges of model or directly

Gusset : To create a rib like structure to provide stiffness to the bent sheet metal part hence increasing the strength of the part.

Flat Pattern: Flat pattern is the representation of the entire sheet metal component in the 2D form of the flat sheet metal with all the bends, cut-outs, holes, and additional features in the form of lines or edges.
