Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

TITLE: Advanced Sheet Metal Design Using NX Cad Challenge_2_Box assembly

OBJECTIVE: To design a sheet metal Box using NX CAD

INTRODUCTION:

Sheet metal is one of the most versatile and widely used manufacturing methods. It has a significantly lower cost than machining cavities into metal blocks. For making a sheet metal component following steps are performed:

• Material selection
• Wall thickness
• Bend radii
• Bend allowance
• K Factor
• Bend reliefs
• Manufacturing process
• CAD platforms

An example of sheet metal design is as below.

In this Challenge, I used NX CAD for sheet metal design.

DESIGN METHODOLOGY:

DESCRIPTION:

All the tools and features used are as below:

1. TAB:

Use this command to create a base feature by extruding a sketch along a vector by a thickness value.

2. BEND:

Modify the model by bending material on one side of the sketching material with a line as reference.

3. FLANGE:

This command creates a flange or extension on the edge of the body selected.

4. NORMAL CUTOUT:

Cuts the model perpendicular to the sketch provided.

5. BREAK CORNERS:

This commands rounds a sharp corner to avoid the manufacturing tool to stop a rigid motion.

6. UNBEND:

It is used to flatten a bend to its reference surface.

7. HOLE:

Used to create holes in the given body according to the size of the body and screw fit type.

8. DIMPLE:

Lifts/Drops an area of the model to create a stamping/punch on the body.

9. Hem flange:

The hem flange command is used to create a mechanical joint which is used for joining inner and outer closure panels.

10. BEAD:

Lifts a material along a counter of a sketch to make punch or stamp around it.

11. REBEND:

Restores a bend from its flattened section to the original.

12. Flat pattern:

Creates a flat pattern feature from the formed sheet metal part.
