Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design

Design of casing by using NX cad

OBJECTIVEVE:-

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 createa 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 radi and bend relief can be easily set as default settings.

DESIGN METHADOLOGY:

1. Select new file in NX cad
2. Saved with Suitable Name
3. Select the XY Plane to draw the Sketch
4. Tab is created with ReferenceSketch
5. Advanced flanges on the edges of bonds create in previous step
6. Bending operation dlone on side of the tab behind the cut out
7. on the tab created as sketch to perfornm normal cut out operation
8. Unbend the Sheetmetal by using unbend command
9. Added the holes where ever required by using Hole command
10. Sketch is created on the Surface oftab to performdimple operation
11. Studio Spline option is selected to create spline curve
12. Rebend the Sheetmetal By using Rebend command
13. Beads also created with reference to holes where placed at required points Dimple operation with referenceto Spline curve
14. Rotated Spline curve to 45 degree
15. final product was achieved as per the inputs
16. Final Touch up was given in Drafting Sheet with suitable Scale

DESCRIPTION

Sketch: Its a basic command to draw 2d modeis.

Tab: A Command to add parameters of an Sketch

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

FIange: it's an operation to extond oft a sheot metal with to one of the eige of an tab

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

HOLE: It's an command used to create different type of hole like topping and normal drilling, on the Surface of an Sheet metal.

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

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

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