Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure

ADVANCED SHEET METAL DESIGN USING NX CAD - ODD SHAPED ENCLOSURE

OBJECTIVE

The objective of this project is to create a sheet metal part for odd shapes in Siemens NX using the sheet metal tool and to create a draft of the sheet metal casing in NX.

INTRODUCTION

• Sheet metal is metal formed by an industrial process into thin, flat pieces. Sheet metal is one of the fundamental forms used in metalworking, and it can be cut and bent into a variety of shapes.
• Countless everyday objects are fabricated from sheet metal. Thicknesses can vary significantly. Sheet Metal application provides an environment for the design of sheet metal parts used in machinery, enclosures, brackets, and other parts normally manufactured with a brake press.
• Siemens NX sheet metal design software incorporates material and process information in sheet metal-specific modelling features: bends, flanges, tabs, cutouts, beads, dimples, louvres, corner and edge treatments, patterns, and other formable features.
• You can also quickly convert solid models to sheet metal components, and create sheet metal parts that enclose other components. More than 85% of Sheet metal industries use NX CAD as a design tool.

DESIGN METHODOLOGY

DESCRIPTION

Sketch - It is a basic and initial operation for creating any kind of sheet metal components.

Tab - It is a base feature that forms by extruding the sketch along a vector by providing thickness or adds material to a plane face.

Extrude - It is to make the 2d sketch in a 3-dimensional body or object by defining its thickness.

Sheet metal from solid - It converts the solid shaped part to shaped sheet metal, and is available in only sheet metal application.

Bend - It is used for bending the material on one side of a sketch line by adding a bend between two sides.

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

Jog - It lifts one side of the sheet metal part through a defined line.

Unbend - It flattens a bend and material adjacent to the bend.

Hole - It creates a whole on basis of circle created.

Dimple - It lifts an area along the contour of a sketch that forms an stamping tool.

Bead - It lifts a material along the contour of a sketch that forms an stamping tool.

Rebend - It restores a bend.

Flat pattern - It creates a flattened pattern from the formed sheet metal part.

Drafting - It is used to draw 2D drawing from a 3D model. The drawing shows dimensions, relations, annotations etc. which is used to manufacture the components.

CONCLUSION 

Thus, creating a odd shaped enclosure is done using sheet metal tools in Siemens NX by understanding the user interface with NX cad.
