2.OBJECTIVE: To design a sheet metal Odd_Enclosure in industrial manner by using Siemens NX Cad.

3.INTRODUCTION: The sheet metal application provides an environment for the design of sheet metal parts used in Machinery, Automotive,Aerospace etc.Enclosures,brackets,and other parts normally manufactured with a brake press.

Design methodology / approach(FLOWCHART):

 5.Feature Description:

Base sketch: For creation of any component sketch is required so that we can create required shape and size of component and also for any other operation sketch is required.

Extrude: Extrude is used to create solid body from the Base sketch.

Sheet Metal from Solid: This command is used to wrap the solid body with sheet metal.

Flange :Flange is used to add extra material to the existing edge at any angle and of any size. For this project of casing design, I added four flanges on different edges. I used full flange having parameters of 5 mm length with material inside the reference edge.

Unbend: Unbend feature is one of the most powerful feature in NX. In industry we have to mark all the marking and sketch on flat sheet metal before it went to actual operations, so this unbend feature allow us to do that activity in Siemens NX software.

Hole: Hole feature is used to generate hole with definite parameter on sheet metal in Siemens NX. We can create different types of holes using this feature

Bead: Bead is similar feature like dimple the only difference is that by using dimple we lift an area while in bead we lift the contour of the sketch. It also added to strengthen the component. For this project, four small beads are applied in the symmetric position as shown in the image below

Rebend: Rebend is the last tool used in this model to rebend the unbend surfaces. while rebending we should Re-bend the faces by selecting them in the reverse order in which they were bend .

 Conclusion: After follow above methods and  tools we successfully design the sheet metal odd shape enclosures.
