Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure

Title of the Project: Advanced Sheet Metal Design Using NX Cad Challenge 5 Odd Shaped Enclosure

Objective: To design a Odd shaped Enclosure with the help of NX advance sheet metal.

Introduction:

Sheet metal is metal formed by an industrial process into thin, flat pieces. Countless everyday objects are fabricated from sheet metal. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate steel or "structural steel".

We can also quickly convert solid models to sheet metal components, and create sheet metal parts that enclose other components.

NX Sheet Metal provides a set of tools within the NX design environment that allows for simple and fast design of sheet metal parts, dependent on their material and manufacturing process, the most common of which is straight brake sheet metal forming.

So, in this project I am going to design a Box Assembly by using sheet metal tools and commands.

DESIGN METHODOLOGY

• while design of an encloseer we have to assuming some parameters so our product will perform well in manufacturing place

which are given below

1. uniform thickness
2. keep holes diameter atleast larger than sheet metal thickness
3. spacing between holes atleast 2 times the sheet metal thickness.

use bead to strenthen our product.

PROCESS FLOW CHART

DESCRIPTION:

• Sketching - Making a 2d drawing such as curves, arcs, circles, points, rectangles and many options to create a drawing or to create features for upcoming designing.
• Extrude - It is to make the 2d sketch in a 3-dimensional body or object by defining its thickness.
• Sheet metal from solid - It converts the solid shaped part to shaped sheet metal, and is available in only sheet metal application.
• Flange - it adds an angular or flat surface on the edge of the surface to create an extended surface with the required directions.
• Jog - It modifies the sketch by living on the one side and adds flange of required length between the two end sides.
• Unbend - It is to flatten the bend sheet metal to form a flat sheet. It helps in making an extra feature like bead, normal cutout on the sheet metal after bending.
• Bead - This is to create a contour shaped accordingly to their sketch in the required direction with required punch/die radius,
• Hole - It is to create a hole on the sketch, or to create a counterbored, countersink and several hole options to do.
• Bead - It is to create a contour or projection on the sheet, as respected with the create sketch.
• Flat pattern - It creates the flat pattern of the sheet metal in a separate sheet for its dimensions and details of the model.

CONCLUSION

• finally i have successfully designed odd shaped encloser by appling standards that relevent to manufacturing process and i have learned how to convert solid to sheet metal.
