Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design

Title of Project –

Advanced Sheet metal design using NX CAD – Casing Design

Objective -

To design a sheet metal casing design using Siemens NX Sheet metal application.

Introduction –

This was first developed by Unigraphics as high-end CAD/CAM/CAE software, later was owned by by Siemens in 2007.

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 –

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.

Conclusion –

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