Title Of the Project :- Create a Sheet metal complex shaped Bracket by using Simens Nx Cad.

Objective :-

Learn the given 2d drawing to create the 3d Model of metal Bracket-II.

Introduction :-

Sheet metal parts are widely used in machinery, enclosure, brackets, and automobile due to its various advantages.
The parts are normally manufactured with break press. Sheet metal is nothing but the thin sheets made from metal of size ranging from 0.5 to 6mm.
In this project I used NX CAD tool for designing the sheet metal bracket. NX CAD is used as design tool in more than 85% of the sheet metal industries.

Design methodology :-

The design methodology used for this project is summarized in below flowchart.

Description Of used Tool :-

Sketch:

For creating any sheet metal surface, we have to first make a sketch. So, I started with creating simple base sketch for creating the tab.
Other than tab, various sketches are also made on different planes or faces for creating other different part during designing.

Normal Cut Out: It is a feature used to cut the sheet metal at the required profile normally

Breaking Corners: It is used to make round corners instead of sharp ones

Unbend :- It's an command used to flatten the created 3d model taking one face as a stationary face.

A Screw Hole :- This command use for create a screw size hole in sheet metal.

Advance Flange: Used create flanges for the curved profiles(peofile should be smooth no sharp corners)

Gusset: Used for strengthening of the sheet metal in perticular bend area.

Flat pattern view :- A flat patternis a 3D sheet metal model in a flattened state. Create Flat Pattern calculates the material and layout required to flatten a 3D sheet metal model.

The part browser displays a Flat Pattern node, and the flattened state of the model displays when this node is active.
