Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure

Title: Advanced sheet metal design using NX Cad:- Odd Shaped Enclosure

Objective

• The objective of this project is to design the odd shaped Enclosure using the Siemens NX Cad software’s sheet metal application.
• To learn and understand use of various tools used in sheet metal design.
• To make a draft of the odd shaped Enclosure modeled.

Introduction

Sheet metal is a type of metal which is formed into thin sheets by various industrial processes. It’s thickness varies from 0.5mm to 6mm. It is widely used in Automobile, Aerospace, roofs for buildings and so on, the most commonly used metals are aluminum, steel, tin, etc.

Sheet metal Enclosures are used to resist corrosion and provide electrical conductivity. The product is widely used for various industrial purposes.

Design Methodology

Description of tool and features

Sheet Metal From Solid

This tool is used to build a sheet metal model that takes its shape from a collection of planar faces.

Normal Cutout

This tool is used to cut the material by projecting a sketch onto the model and cutting perpendicular faces intersected by the projection.

Flange

This tool is used to create a flat flange at an angle to a planar face by creating a bend between two faces.

Extrude

This tool is used to create a feature by extruding a section or sketch along a vector.

Jog

This tool is used to Lift the material on side of the sketch line and add a flange between the two sides.

Unbend

This tool helps to flatten a bend and the material adjacent to the bend so that the holes or other features can be created.

Dimple

This tool is lift an area of the model inside a sketch which simulates the stamping tool.

Bead

This tool is lift an area around a contour which simulates the stamping tool.

Rebend

This tool is used to restore an unbend feature to its previous bent state, along with the features added after unbend feature.

Flat pattern

This tool is used to create a flat pattern from the formed sheet metal part.

Drafting

Drafting is used to convert 3d models into 2d technical drawings.

Louvers

This tool is used to pierce the model with a sketch line which simulates the stamping tool.

Hole

This tool is used to create holes of various type like screw type, counter bore, counter sink etc.

Conclusion

Thus tools and features in Nx Cad sheet metal application were understood and the odd shape enclosure was created and the model was drafted.
