Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure

OBJECTIVE:-

To design a sheet metal odd-shaped enclosure using NX Cad software with suitable commands to achieve the final product as per the inputs.

INTRODUCTION :

Sheet Metal is a type of material that is flattened into thin sheets. Sheet metal is made by taking a large cast in and rolling it into a long ribbon of the thickness it wants. This flat metal is rolled into a coil and sent directly or cut the metal into sheets before being sent to a machine shop.

The sheets are made from metals such as aluminum, brass, copper, steel, tin, nickel, and titanium. The sheet’s thickness depends on the material needed for a project. Thicknesses can vary from 0.15 -6.00 mm significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate steel or “structural steel.”

DESIGN METHODOLOGY

The design methodology is explained by the flow chart as follows :

START NX WITH SHEET METAL

SKETCH HAS MODE & EXTRUDE

SHEET METAL FROM SOLID IS PERFORMED

FLANGE IS CREATED & JOGS IS CREATED ON THE OTHER SIDE

UNBEND IS PERFORMED FOR THE MODEL

BEAD IS CREATED ON THE SURFACE

HOLE IS PERFORMED AS PER THE DESIGN

FLATE PATTERN IS SHOWN AT THE END

Description

nx has been opened and selected sheet metal design with unique name
creating sketch is xy axis from given data
sketch as reference extrude has been down
converting this solid model into sheet metal
sheet metal is formed thickness of 3 mm and bend radius of 3mm
then flange is created on one edge for 20mm
sketch has created to form jog comand
with the reference of sketch, jog has been performed
unbend is down for this model to check model con be happen or not
now again the sketch takes the role on the top of the unbend surface
with the help of sketch bead is performed to give max strength to the model
as per the design, consideration hole is maded
finally rebend is used to see the final out put

Creating the solid body

The sketch for the solid body has to be created. Then the sketch is to be extruded using Extrude command which is available in the modelling workbench.
