Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

Title of the Project: Box Assembly in advanced sheet metal design using NX CAD

Objective: To create Box Assembly in advanced sheet metal design using NX CAD

Introduction: Sheet metal which has various advantages like metal working, manufacturing and easy to work on operations such as bending,cutting during industrial process.Box assembly design has different parts to create a closed enclosure.

This project on Box Assembly has

1. Main box which has features like dimple,bred and Hem
2. Lid
3. Hinge

Design methodology / approach (To be explained with the help of Flowcharts only)

Description (Need to explain tools/ Features used while designing)

1. Main box:

• Tab: Draw the sketch and add thickness of 1 mm

• Add flange: Flange with bend radius 10, angle 90 deg and length of 200 mm

* Flange with length 70 mm sides

• Close corners: close and relief option used to close corner

• Add flange and hem

• Mirror body: Mirror the body using YZ Plane

• Unite:It is used to combine the mirror body and the box

• Add dimple: sketch and use depth of 2 mm for the dimple

• Unbend

• Rebend

• Add bred: Depth and radius of 2mm and mirror the bred feature

• Add hem:

2.Lid

* Use Datum plane at a distance of 203 mm

• Tab:Sketch and add tab thickness 2 mm

• Add flanges:It is added to the sides of the Lid component

3.Hinge

• Tab:Sketch and add tab thickness of 1 mm

• Break corner: This feature is used to create curve edges and 10 mm in radius is given

• Add flange:Flange with 40 deg and length 4 mm is given

• Add open loop hem: Bend radius 5 mm and sweap angle 325 deg is given

• Unbend

• Sketch and Normal cutout:Cutout having depth of 5mm

• Rebend:Rebend after normal cutout feature

• Mirror body: Mirror the body using XZ Plane

• Tab: Sketch and add thickness 1mm

• Break corner: Break corner to curve the edges having radius 10mm

• Add flange:flange having bend radius 1 mm and length of 14.2 mm

• Hem: Open loop type hem having Bend radius 5 mm and sweap angle 325 deg

• Unbend:To sketch and cutout material

• Normal cutout:Remove material from the tab

• Rebend:To form the hem that was created
