ODD SHAPED ENCLOSURE USING NX CAD

ODD SHAPED ENCLOSURE USING NX CAD

OBJECTIVE:

To design an odd shaped enclosure using NX CAD tool.

INTRODUCTION:

The learning of steps & features involved in designing an odd shaped enclosure using a NX CAD tool.

DESIGN METHODOLOGY:

PROCEDURE:

STEP 1:

Start NX CAD. Then set the global parameters as per requirements.

Menu-->Preferences-->Sheet metal

STEP 2:

Design a base sketch to form a solid profile and extrude it.

EXTRUDE: Extrude is a method of defining three-dimensional geometry by translating a two-dimensional sketch normal to the sketch plane.

STEP 3:

Convert it into sheet metal using sheet metal from solid.

SHEET METAL FROM SOLID: This tool is used to convert the solid profile into sheet metal.

STEP 4:

After forming it into a sheet metal, add flange & jog to form a profile.

FLANGE: The flange feature creates a flat bended profile at an angle to a planar face.

JOG: The Jog is used to create a flange by lifting the material on one side of the sketch line drawn.

STEP 5:

After creating flange, unbend the profile with the use of Unbend option.

UNBEND: This feature is simply used to flatten the bended profile.

STEP 6:

After that, create a sketch for creating a beads. Then select bead option with circular cross section and give proper radius and depth.

BEADS: Beads is used to lift a material along the contour of the sketch.

STEP 7:

Now, sketch six reference points for holes on profile which was unbend before. Then create holes with their respective hole size and fit.

HOLE: A hole feature is used to create a holes on the model which is mostly used for assembling & mounting.

STEP 8:

Finally rebend the model to get the bended view of the model.

REBEND: Rebend is used to restore the model to its bended state.

STEP 9:

After rebending create a flat pattern view of the model for drafting purpose.

FLAT PATTERN: Flat pattern is used to create a flat pattern view which is used for drafting purpose since it was required for manufacturing purposes like lasercut etc.

HERE ARE SOME OF THE SCREENSHOTS OF THE MODEL:

DRAWIN SHEET:

CONCLUSION:

Thus the Odd Shaped Enclosure has been designed with the use of NX CAD tool and learned about feature involved in creating the sheet metal model.
