Advanced Sheet Metal Odd Shaped Enclosure Design Using NX Cad
Sheet Metal Design of Odd Shaped Box Assembly Using NX CAD
Objective: To design a Sheet Metal Odd Shaped Box Assembly by using Siemens NX Sheet metal workbench.
Introduction:-
Sheet metal enclosures are fabricated by 'cold forming', where the metal is clamped and bent in machines called 'press brakes'. As a result, metal typically cannot be formed into a true 90 degree corner. Instead, the corners are curved. You’ll find them in everything from junction boxes to control panels for industrial machinery. These enclosures are simple, versatile and extremely tough, so they’re in high demand for electrical projects and are often custom-fabricated.
Design Methodology
DESCRIPTION
Sketch: Sketch tool was used for creating the sketch required for tabs, cut outs, dimples, beads etc.
Extrude: To create a solid body other sheet metal we use extrude command and select the drawn closed 2D sketch and provide the length or depth of the solid.
Sheet Metal from Solid: This command is used to covert a solid body surfaces into a sheet metal body of specified thickness.
Flange: A flange is an external or internal ridge. Flanges were used to create the side walls of the box as well as hinges.
Bead: Beads are used to enhance the strength of the sheet metal part. It lifts the material according to a sketch that simulates a stamping tool. Here, four beads were used at the bottom of the box assembly.
Unbend: This feature is used to unbend the adjacent bends and flatten them.
Rebend: It is used to rebend the unbended corners after adding any features on the faces.
Flat Pattern: After the object is completely finished and to produce the machining drawing we use flat pattern option to create the detailed flat sheet with all the features marked on it along with its description.
Drafting: We can convert the flatpattern of the model to a 2D draft on a drafting sheet.

CONCLUSION
This project underlines the tools and considerations for designing a odd shaped sheet metal box. It also underlines sheet metal application in NX and advantage of NX as a software for sheet metal design and its application as sheet metal bracket.
