Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design

OBJECTIVE:-

To design a sheet metal casting using NX Cad software with suitable commands to achieve the final product as per the inputs.

INTRODUCTION :

In Sheet metal Application we can create a uniform thickness Sheetmetal parts using basic features Such as Tabs, flange and jogs, we can also do bend corners, cut out, bead etc…features.

The Sheetmetal application provide an environment for the design metal parts used in machinery, Automotive and Aerospace Enclosures, Brackets and other parts are normally manufactured with break press.

The complex sheet metal part can be designed in the Solid model work Bench and then we convert in to Sheet metal part. We can also import, clean up and convert a non Sheet metal part into a valid Sheet metal part. Flat pattern Sheetmetal data can be used for the manufacturing process. The material parameters such as thickness, bend radii and bend relief can be easily set as default settings.

DESIGN METHADOLOGY :

Select new file in NX cad

Saved with Suitable Name

Select the XY Plane to draw the Sketch

Tab is created with Reference Sketch

Advanced flanges on the edges of bends create in previous step

Bending operation done on side of the tab behind the cut out

on the tab created as sketch to perform normal cut out operation

Unbend the Sheetmetal by using unbend command

Added the holes where ever required by using Hole command

Sketch is created on the Surface of tab to perform dimple operation

Studio Spline option is selected to create spline curve

Rebend the Sheetmetal By using Rebend command

Beads also created with reference to holes where placed at required points Dimple operation with reference to Spline curve

Rotated Spline curve to 45 degree

final product was achieved as per the inputs

Final Touch up was given in Drafting Sheet with a suitable Scale

DESCRIPTION:

Sketch:- It’s a basic command to draw 2d models.

Tab:- A command to add parameters of a Sketch

Bend:- It’s an operation to bend the tab at a particular position with reference

Flange:- It’s an operation to extend a sheet metal to one of the edges of a tab

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

HOLE:- It’s a command used to create a different type of holes like tapping and normal drilling, on the Surface of a Sheet metal.

DIMPLE:- It is a projection command of a particular shape with reference to a sketch with a certain depth.

BEAD:- It is also the type of projection to deform the shape at a certain point with reference to the sketch and also gives strength to the material.

REBEND:- This command is used to re-bend the already flattened sheet metal.
