BRACKET DESIGN USING NX CAD

BRACKET DESIGN USING NX CAD

OBJECTIVE:

To design a sheet metal Bracket using NX CAD tool.

INTRODUCTION:

The learning of steps & features involved in designing a sheet metal bracket 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 and create a base with contour flange option

CONTOUR FLANGE: The contour flange feature creates a base by extruding the sketch perpendicular to the sketched plane.

STEP 3:

Create a sketch that has to be cutout from the base with Normal Cutout.

NORMAL CUTOUT: A cutout profile is used to remove the material from the base.

STEP 4:

Then apply the fillet at the edges of the sheet metal using break corner.

BREAK CORNER: The break corner is used to make a smooth edge at the corners.

STEP 5:

After applying fillet, 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 three 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.

HERE ARE SOME OF THE SCREENSHOTS OF THE MODEL:

CONCLUSION:

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