Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

Title of Project –

 Advanced Sheet metal design using NX CAD – Box Assembly

Objective –

TO design a sheet metal box assembly using Siemens NX Sheet metal application.

Introduction –

NX sheet metal design incorporates material and process information in sheet metal-specific modelling features: bends, flanges, tabs, cut-outs, beads, dimples, louvers, corner and edge treatments, patterns and other formable features.

Design Methodology –

Flow chart -

  Features used –

1. Sketch – It’s the base 2D drawing where it’s drawn on selecting a plane.
2. Tab - It’s base feature part of the sheet metal.
3. Flange -Its extended part of sheet metal obtained by selecting edges.
4. Unbend – this feature unbends the sheet metal part selecting any face as stationary face.
5. Rebend – It brings back the sheet metal to its original shape.
6. Dimple – It’s a kind of die press applied on sheet metal to obtain the required to obtain the desired shape.
7. Bead - This feature gives strength to sheet metal part.
8. Hem flange – It modifies the edge of sheet metal by folding it over onto itself.
9. Mirror Feature – created the exact mirror sheet metal part when given a reference plane.
10. Normal cut out - Cuts material by projecting a sketch onto a model and then cut perpendicular to faces intersected by projection.
11. Closed corner – Closes corner where two adjacent flanges meet by extending the bends and flanges.

Conclusion –

By performing this sheet metal modelling, I have learned to use and apply various features like tab, flange, bend, normal cut-out, closed corner, mirror feature, dimple, bead, unbend, rebend.
