Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

Advanced Sheet metal Design using NX cad Challenge 2 box assembly.

Objective: - To design a sheet metal box assembly using NX Cad metal application.

Introduction: -

Sheet metal is one of the fundamental forms of metal working it can be cut and bend into a variety of shapes, using the powerful Cad software siemens NX PLM we can produce or generate several sheet metal products. The software is mostly used for design analysis and manufacturing.

The box assembly consist of 3 Parts.

1. Box
2. LID
3. Hinge

Design methodology: -

Various steps performed while designing the model are explained as follow,

• Box:

1. Tab: Draw a sketch in XY plane and add Tab of given thickness.
2. Flange: Flanges are added normal to XY planes using given dimensions.
3. Closed corner: By using closed command to close the corner,
4. Add flange and Hem: Flange Is added using given dimensions and hem is added at the edge.
5. Mirror body and Unite: Use mirror body feature to Create the box, after mirroring use unite feature to unite both parts of the box.
6. Add dimple: Add dimple on adjacent sides using given dimensions and another dimple at the bottom side.
7. Unbend and re-bend: Unbend and re-bend the metal sheet
8. Add Bead: Add bead on the bottom plate using given dimensions and use mirror body feature.
9. Add hem flange: add hem along all upper edges of plates using given dimension

• LID:

1. Tab: create new datum plane, create new sketch using given dimension and create tab of given thickness.
2. Add flanges: Add flanges at the top edge of adjacent sides using given dimensions.

• Hinge:

1. Tab: Create new sketch on the back plate and add tab using given dimensions.
2. Add flange and hem: - Add flange and hem using given dimensions.
3. Make normal cut-out: Draw new sketch on sheet metal surface and use normal cut-out feature to create required cut-out.
4. Re-bend: Re-bend the metal sheet using re-bend command
5. Mirror: - use mirror body feature to create newly created bodies.
6. Tab: Draw new sketch and create new tab using given dimensions.
7. Break corner: use break corner command to add round shapes at the corner using given dimensions
8. Add flanges and Hem: Add flanges and hem using given dimensions,
9. Unbend and make normal cut-out: unbend the sheet metal, draw new sketch and use normal cut-out feature to make cut on the Sheetmetal surface.
10. Re-bend the Sheet-metal: Re-bend the sheet metal to create a hinge

CONCLUSION:

In this modelling box Assembly, I learned and practised a lots of command like mirror, Break corner, re-bend, hem, flange, Normal cut-out etc.
