MODELING OF BOX ASSEMBLY ON NX CAD

Objective :

To create Sheet metal box assembly by using of NX CAD software.

Introduction :

Sheet metal is metal formed by an industrial process into thin, flat pieces. Sheet metal is one of the fundamental forms used in metal working, and it can be cut and bent into a variety of shapes. Countless everyday objects are fabricated from sheet metal. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate steal or "structural steel".

Design methodology :

Tab

Workflow :

Create 2d sketch on given dimension (L- 200mm b - 200mm)

select tab option and also select 2d sketch

Give thickness of tab 1mm and click ok

Flange

Workflow :

Select flange optiotion and select required edge to bend

Give length and angele (L- 70mm , Angle - 90° )

Closed Corner

Workflow :

Select closed corner option and select close relief optition

Select two Adjacent bend face and click ok

Mirror Body

Workflow :

Select mirror body optition

Select required body to mirror and plane

Unable associative and fix at current timestamp

Unite

Workflow :

Select unite optition

Select two body need to merge and click ok

Dimple

Workflow :

Draw 2d sketch on given dimension (Radius 10mm)

Select dimple optition

Give depth and radius to punch (2mm)

Bead

Workflow :

Draw 2d sketch (dia 10mm circle )

Select Bead optition

Select 2d sketch need to bead and click ok

create mirror of bead feature other three side (Reference Bottom plane)

Tab

Workflow :

Create 2d sketch on given dimension (L- 20mm b - 55m)

Select tab option and also select 2d sketch

Give thickness of tab 1mm and click ok
