Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

Title: Advanced sheet metal design using NX Cad:- Box Assembly

Objective

• The objective of this project is to design the sheet metal Box Assembly 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 Box assembly 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.

Description of tool and features

Tab

This tool is used to create a base feature by extruding a sketch along a vector by given thickness value.

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.

Closed corner

This tool is used to close a corner where 2 adjacent flanges meet , by extending the bends and flanges.

Break corner

This tool is used to make the corners of a tab or flange round or create a chamfer.

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.

Hem Flange

This tool is used to fold the edge of the sheet metal flange over onto itself for safe handling and increasing the stiffness.

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.

Mirror

This tool is used to replicate features, faces, and bodies about a plane or a planar face.

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.

Conclusion

Thus tools and features in Nx Cad sheet metal application were understood and the Box assembly was created and the model was drafted.
