Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

Box Assembly Design

Objective:

To design a sheet metal box assembly using NX.

Introduction:

Box assembly is like a container which consists of base, cover lid and hinges to open and close the cover lid of the box.

Design Methodology:

Description:

To design the box assembly of a sheet metal we need few tools to design as per the input. Those tools are discussed in detail below.

1. Tab:

Tab is used to create base of the sheet metal of 1mm thickness. Using proper dimensions provided in the input like length and width, tab can be created.

2. Flange:

Flange is used to create a flange for particular distance by providing proper angle, length and bend radius.

3. Closed Corner:

Closed corner tool is used to cover the corners in proper and aesthetic way for the sheet.

4. Open Hem:

Open hem tool is used to hold the sheet inside the hem.

5. Mirror Body:

Mirror body is used to mirror the body with respect to mirror plane.

6. Unite:

Unite tool is used to merge two bodies of an object into single body.

7. Dimple:

Dimple tool is used to create a stamp on the sheet metal up to defined depth by sketching the dimple.

8. Unbend:

Unbend tool is used to undo the bending process by making it flat to create holes and stamping process.

9. Rebend:

Rebend tool is used to create the bend of the unbend sheet metal.

10. Bead:

Bead tool is used to create circular stamp on the sheet metal up to defined depth by sketching the circle of particular diameter and its dimension from reference or datum.

11. Mirror Feature:

Mirror feature is used to mirror the feature created on the body with respect to mirror plane.

12. Closed Hem:

Closed hem is used to bend the sheet metal with respect to its face without providing any clearance between them.

13. Datum Plane:

Datum Plane is used to create a reference plane to create sketches on that particular plane.

14. Break Corner:

Break corner tool is used to remove sharp corners by providing fillet or radius for the sheet metal.

15. Open Loop Hem:

Open Loop Hem is used to create a circular loop of a sheet metal by providing a bend radius and sweep angle.

16. Normal cut-out:

Normal cut-out tool is used to remove material normal to the sheet metal using drawn closed curves.

17. Flat pattern:

Flat pattern is used to create sheet metal of unbend to create bend axis and details of bending.

Conclusion:

Box assembly model has been designed as per the guidelines and dimensions provided in the input.
