Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design
Title of The Project: Advanced sheet metal design using NX CAD 11 challenge 1.
Objective: To design a sheet metal casing design using NX CAD.
Introduction: NX CAD is an advanced high-end cad software. It is owned by siemens. Nx cad is mostly used for designing parts made up of sheet metals (ex: aeroplanes, automobile etc.)
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. Sheet metal has a uniform width.
Design Methodology:
Description:
- Sketch: the feature that allows us to sketch the various shape and cross-section of the model.
- Tab: tab is the basics feature of sheet metal designing; it is basically extruding a sketch along a vector by uniform thickness.
- Flange: used to create an extended part of sheet metal.
- Unbend: used to obtain a plain sheet metal without any bends. It is done by selecting a stationary face and unbending the other bend face w.r.t the stationary face.
- Re bend: returns the model to the original way.
- Dimple: to create a pitch up or down the surface.
- Bead: used to give the sheet metal extra strength.

CONCLUSION: By doing this challenge I have learnt the usage of basic sheet metal commands and feature and modelled the casing.
