Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

BOX ASSEMBLY:

INTRODUCTION:

• STRAT IN THE NX 12
• CREATE ANEW SHEET METAL model called casing part.
• create a sketch in the XY plane
• draw a rectangle centered at the origin with an x-length of 200 mm and a y width of 150mm
• exit the sketch mode.

2.change design parameter.

1. Go to the menu
2. next step preferences
3. 
4. sheet metal.
5. 
6. global parameters 1mm

Adding a solid sheet.

• the tab is used to sketch is converted into a thick sheet at a thickness of 1mm.
• a sketch can be created by using the tab tool also sketch is highlighted in a blue colored box.

ADDING FLANGES.

• Click on the flange command.

• use a length 200mm angle of 90 degrees and apply the flange on the shown edge of the metal sheet.

• DO the similar operation on another side provide the same values.

• do similar operations on the front and rear sides.

• do the same operation on the left side of the sheet metal and the same value provided.

• flange open surface also provides length 0.02 and angle and 90 degrees.

• after creating the flanges.
• do the same operation on the opposite also.

• after creating the flanges create on the flange at the length of 6.5 mm angle 90 degrees.

CLOSE CORNERS:

• Select the close corner command
• go with the close and relief corners.
• at the gap of 0mm.
• treatment at the close.
• overlap close select.
• select the blend.

• use a similar operation on another side.

APPLYING HEM :

• Select hem command
• selects the corner give the length 3mm radius 0.5mm.

• do a similar operation on the opposite side.

MIRROR:

• Select the mirror body command
• to select the body and required plane.
• make sure in settings click the fix at the current timestamp
• shows in the below figure.

UNITED:

• SELECT THE TWO BODIES TO JOIN.

DIMPLE:

• BY USING THE DIMPLE COMMAND
• create the sketch and on the metal surface.

• set the depth option to 1mm and sidewalls to material inside.
• expand the rounding field by left-clicking on it.
• set all the parameters of the rounding field to 1mm.
• click ok.

• do the same operation on another side.
• by projecting a sketch on the opposite side.
• do a similar operation on the bottom of the box.

TOP SURFACE OF THE BOX:

• create the sketch on the surface by using the datum plane.

APPLYING HEM:

• APPLY THE HEM ON THE CONER OF THE BOX.
• Do a similar operation on the required corners.

• created the sketch by using the respective datum plane.

• by using the tab add thickness to the sheet metal.

• add flanges at the sides of the surface.

• similarly, add the same operation on another side.
• create the sketch on the front side of the box.

• use the tab command to create the sheet.

USE THE BREAK CORNER COMMAND :

• use the remove to a sharp corner.
• at the radius of 10 mm

CREATE THE FLANGE ON THE TAB SURFACE :

• Select the edge
• to provide the 4mm and angle 40 degrees.
• bending radius is 0.5mm.

• do the same operation on the flange.

• applying the hem:

• apply hem on the flange
• go with the open-loop and select the edge.
• and bend outside.
• provide bend radius 5mm
• sweep angle 325mm.
• and unbend it and create the sketch on it

• sketch on the surface

• use Normal cut-out the surface.

REBEND the surface.

• by using the re bend command take them into their original position.

• by using the mirror body.
• mirror it on another side.

• do a similar operation on the top.

BEADS:

• FIRST CREATE THE SKETCH.

• by using the bead command
• in the bead dialog box select the circle you have just drawn.
• set the depth and radius to 2mmand the cross-section to circular.
• the die radius to 2mm.

• by using the mirror feature
• select the bead and its corresponding sketch as a feature to mirror.
• do the same operation to another side.
• The flat pattern command is used to create the flat pattern.

DRAFTING:

• go to the application and select the drafting.
• Select the new page and required size like A3.
• then select the base view
• to adjust the sheet metal view like top view, front view.
• for the moment, the flattened version is not visible .to make it visible, go in the part navigator and expand the model and model tree.
• in the base
