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 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 suitable Scale

DESCRIPTION:

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

Tab :-    A command to add parameters of an Sketch

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

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

UNBEND :- It’s an command 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 tapping 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.

CONCLUSION :-

  By this challenge I came to know about the application of various commands and using given inputs finally achieve the final product.
