DESIGNING ODD SHAPE ENCLOSURE IN NX

DESIGNED BY,

ASHIS TARAI

OBJECTIVE;-

1. To Design An Odd Shaped Enclosure Using NX CAD.
2. To Learn The Features Involved In Creating An Odd Shaped Enclosure.

INTRODUCTION;-

Sheet metal is metal formed by an industrial process into thin flat pieces. Sheet metal is one of the fundamental forms used in metal working and it can be cut and bent into variety of shapes. Sheet metal are using in various industry like Automobile, Aeronautics medical tables, beverage cans. Countless everyday objects are fabricated from sheet metal. thickness can vary significantly extremely thin sheets are considered foil or leaf, and pieces thicker than 6mm are considered plate steel or structural steel.

NX formerly known as “UNIGRAPHICS” is an advanced high end CAD/CAM/CAE which has been owned since 2007 Siemens PLM Software. In 2000 UNIGRAPHICS purchased SDRC IDEAS and began an effort to integrate aspect of both software packages into a single product which becomes UNIGRAPHICS NX or NX.

The odd shaped enclosure design is obtained by using NX sheet metal workbench. These enclosure has some important feature like flange, bead ,hole etc.

DESIGN METHOLODOLY;-

DESCRIPTIONS OF THE FEATURE;-

1.Sketch;-It’s the basic feature of any kind of operation.

2.Tab:-It’s base feature that forms by extruding the sketch along vector by providing thickness or adds materials to the plane face.

3. Sheet metal from solid body;- It is used to convert the solid shaped body into sheet metal shape.

4. Flange;-It adds a flat flange on basis of edge at an angle to a planner face and adds bend between them.

5. Jog;- It’s used to create jog along the curve.

6. Bead:-lifts the materials along the counter that simulates stamping a tool.

7..Bend:- Modifies the model by bending material on one side of sketch line adding a bend between the two sides.

8.Unbend:-It flattens a bend and material adjacent to the bend.

9.Hole: It creates a hole on basis of circle created.

10. Re bend:-It stores a bend.

11.Drafting:-It is the creation of drawing for the purpose of determining how the product should be created.

12.Flat Pattern:- It is used to create flat pattern for tolling technician for manufacturing purposes.

PROCEDURE:-

Step 1: Create a sketch in front plane with the necessary dimension and convert in 3D part by extruding it with the distance of 2OOmm.

Step 2: Then wrap the solid with the sheet metal by using the feature sheet metal form body with the thickness of 3mm and bend radius 5mm by selecting the top surface.

Step 3: Create a flange on one side of the large surface with the length of 2Omm and then create a bend by using jog line feature on the other side with the 20mm.

Step 4: Unbend the bended surface.

Step 5: Create a bead feature on the top surface by create a sketch and provide the bead radius of 3mm to it.

Step 6: Then create a hole on the top surface with the circle diameter of 1Omm.

Step 7: Re bend all the surfaces.

Step 8: Create a flat pattern with respect to top surface.

Step 9: Save the file.

Sheet metal enclosures

It is use to resist corrosion and provide electrical conductivity. The product is widely used for various industrial purposes.

Applications:

• Construction and engineering i
• Automobile
• Pharmaceutical i
• Food & beverages

Features:

• Study
• Corrosion
• Precision
• These enclosures are epoxy coated to ensure good

CONCLUSION:-

Thus the designing of a sheet metal odd enclosure by using NX CAD application has been created and required drafting sheet with created with proper parameter in NX.
