Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure
DESIGN OF SHEET METAL ODD-SHAPED ENCLOSURE
OBJECTIVE : To design a sheet metal odd-shaped enclosure within sheet metal workbench in NX CAD.
INTRODUCTION :
Sheet Metal Fabrication is the process of forming parts from a metal sheet by punching, cutting, stamping, and bending. 3D CAD files are converted into machine code, which controls a machine to precisely cut and form the sheets into the final part. Odd-shaped Enclosure is a one of the Sheetmetal component used to cover or protects the parts with in it. ... It can be designed by using NX-cad sheet metal. NX, formerly known as "Unigraphics".
DESIGN METHODOLOGY :
DESCRIPTION :
features used :
Sketch : Sketch creates a 2D drawing for the model of having several sketch commands like lines, rectangles, circles, etc.
Tab : Tab creates a Base Extrude feature for the given Sketch with thickness and direction.
Bend : Bend is used to bend the created Base Extrude in required direction and angle.
Flange : Flange creates an aditional body by given angel from the edge of existing sheet metal body.
Hem Flange : Hem Flange is used to modify the model by folding the edge of the sheet metal flange over onto itself.
Closed corner : It is used to close to corners of flanges bt extending flanges.
Break corner : Break corner creates smooth rounded edges for the sheet metal.
Unbend : Unbend is used to bend model into original state .
Rebend : Rebend is used to bend model back into designed shape.
Dimple : Dimple lifts the area of the model inside the sketch for creating stamping press to the model.
Bead : Bead lifts the material along the contour of sketch that simulates a stamping tool.
Hole : Hole is used to create different types of holes on the sheet metal model.
Flat pattern : This feature is used to create a flat pattern from the formed sheet metal part.
Contour Flange : This command creates main base flange or second flange by extruding sketch in sheet metal application.
MODELLED ODD SHAPED ENCLOSURE :
CONCLUSION : Hence design of Sheet metal Odd-shaped enclosure is completed.
