Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure
Title of the Project
Odd Enclosure
Objective
Siemens NX formerly known as Unigraphics was used to design the casing.
Introduction
Sheet metal forming is the process in which a flat sheet is converted to desired shape by (bending, cutout, embossing, etc.) without causing any rupture to the sheet metal.
Sheet metal thickness varies from 0.4mm to 6mm, thin sheet metal is called leaf or foil and thicker ones are called as plate.
few examples of the industries which are reliant on sheet metal are aerospace, automobile, oil and gas, electronics, food service etc.
Design methodology
Description
Extrude- To create a 3D solid model from 2D sketch we use this command.
sheetmetal from solid body- to wrap the sheet metalon the solid body to obtain its shape we use this tool
Flange-feature consisting of a face and bend connected to the existing face along straight edge
Jog-it creates a bend on one side of the line drawn and on the other side of the line it pulles the material up
Unbend/ Re bend- done to ease the next operation
Bead-it is created by punching in the sheet metal which adds stiffness to the sheet metal.
Hole-operation to create a hole in the sheet metal
Flat pattern-it provides the information of all the features.
Drafting- it is last step done to communicate the details of the model.
