Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure
DESIGN AND MODElING OF ODD SHAPED ENCLOSURE BY USING SHEETMETAL IN NX-12
OBJECTIVE
To design and model the sheet metal odd-shaped enclosure in nx-12 by using some basic feature and tools.
To learn how to covert sheet metal from solid geometry .
To master the user interface and basic feature of sheet metal application in nx-12 like solid, jog ,flat pattern ,and replace views
INTRODUCTION
Sheet metal design and fabrication
sheet metal fabrication is the process of forming part from a metal sheet by punching , cutting ,stamping, and bending.
3d cad files are converted into machine code ,which control a machine to precisely cut and forms the sheet into final part .
Sheet metal part are known for their durability ,which makes them great for end use application .part used for low volume
Prototypes and high volume production runs are most cost- effective due to large initial setup and material coasts.
Because part are formed from a single sheet of metal ,design must maintain a uniform thickness.be sure to follow the design requirement
And tolerance to ensure parts fall closer to design intent and cutting sheets of the metals .
Design methodology / approach
Description: tool/ features used while designing the odd shaped enclosure.
1 sheet metal from solid : in siemens nx sheet metal from solid use to bulid a sheet metal model that takes its shape from a collection of planar face.
2 flange: flange feature is used to create an extended portion or bend to the selected edge . While creating flange we have to set the different parameter such as length of the flange ,its angle ,length referance inset other parameter like bend radius,bend radius ,bend relief , and neutral factor is also needed to be considered .
3 jog : lifts one side of the sheet metal part through a defined line. Ads flange between the stationary side the lifted side.
4unbend : this feature is used to flatten the sheet metal part for further design operation.
5 Bead : the bead is like a raised rib in the sheet metal panel. It requires that you have a least one sheet metal panel
In the active part as well as an open or closed -loop sketch.
The bead is another feature that has only a button for option on the command bar.
6 RE bend : re bend feature is used to get the original bend shape after performing forming operations like a dimple, bead.
7 flatt pattern : this feature is used to create an instance of the flat shape and size of the sheet metal that required to create the final part
drawing
CONCLUSION :
1 sheet metal odd shaped enclosure is designed sucessfully in the nx-12 sheet metal environment.
2 basic features of the sheet metal environment of nx-12 like sheet metal from solid ,jog, flat pattern and replace view are learned and applied in design.
