Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure

1. TITLE

Create enclosure with odd shapes and angles

2. OBJECTIVE

To create an enclosure using various features in NX sheet metal workbench

3. INTRODUCTION

NX Cad

NX formerly known as unigraphics is one of the world’s most advanced and tightly integrated CAD/CAM/CAE product development solution. The software has powerful hybrid modeling capabilities by integrating constraint based feature modeling and explicit geometric modeling.

Sheet Metal (SM)

Sheet metal is available in flat pieces or coiled strips that originate from many different metals such as aluminum, brass, copper, steel, tin, nickel, or titanium. It is formed into thin, flat pieces and is one of the most basic materials used in metalworking thanks to its malleable properties that enable it to be cut and bent into a multitude of shapes. Perhaps without realizing it, we are surrounded by a myriad of common objects that are fabricated from sheet metal: from automotive bodies to aerospace fuselages and wings, up to medical tables, sinks, roofs of buildings, and machinery.

There is a significant variation in the thickness of sheet metal; the thinnest sheets are referred to as foil or leaf, and pieces with a thickness greater than 6 mm (0.25 in) are considered plate.

4. DESIGN METHODOLOGY

5. DESCRIPTION

Flange

It adds a flat flange on basis of edges at an angle to a planar face and adds bend between them

Unbend

It flattens a bend and material adjacent to the bend

Rebend

It restores a bend

Mirror

It is used to create same features or sketches on basis of plane or sketch

Bead

It lifts a material along the contour of a sketch that forms a stamping tool

Sheet metal from solid

Builds a sheet metal model that takes it’s shape from a collection of planar faces

Hole

Adds a hole to one or more bodies in a part or assembly

Flat pattern

Creates a flat pattern feature from the formed sheet metal part
