Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

Design of Sheet Metal Box Assembly Using NxCad

Objective:

The objective of this tool is to create a sheet metal box assembly using the Nx cad tool

Introduction:

Sheet metal is metal formed by an industrial process into thin, flat pieces. Sheet metal is one of the fundamental forms used in metalworking, and it can be cut and bent into a variety of shapes. Every day countless 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 steel or structural steel

Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter.

Design Methodology:

Description of tools/features:

1. Sketch

 It's a basic 2d sketch to any design.

2. Tab

Creates a bae feature by extruding a sketch along a vector by a thickness value, or adds material to planar face.

3. Flange

Adds a flange at an angle to a planar face and adds a bends between the two faces.

4. Unbend

Flattens a bend and the material adjacent to the bend

5. Rebend

Restore an unbend feature to its previous bent stage , along with any feature added after the unbend feature.

6. Dimple

Lift an area of the model inside or outside a sketch that simulates a stamping tool.

7. Bead

Lifts material along the contour of a sketch that simulates a stamping tool creates a solid using a path and cross-section shape.

8. Unite

Combine the volume of two or more solid bodies into a single body.

9. Normal cutout

Cuts material by projecting a sketch onto the model and then cutting perpendicular to the face intersecting by the projection.

10. Mirror Feature

Copies a feature and mirrors it across a plane

11. Hem Flange

Modifies the model by folding the edge of a sheet metal flange over onto itself for the purpose of age handling or to increase edge stiffness.

12. Break corner

 Rounds or chamfers a sharp corner of a tab or flange.

13. Closed Corner

Closes a corner where two adjacent flange meets by extending the bends and flanges.

14. Mirror body

Copies body and mirrors it across a plane.

15. Flat pattern

Create a flat pattern feature from the formed sheet metal parts.

16. datum plane

     Create a boundary plane used to construct other features.
