Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

• Title of the Project : - Design the Box Assembly

• Objective : -
  • Draw the fukky define sketches and understand and implement features to complete the model in NX SheetMetal
  • Understand user interference in NX sheetmetal
  • Gain knowleadge of Sheetmetal tools such as Tab, Flange, Hole, Mirroring of sketch and features, Blend, Bend, Unbend and rebend, Bead etc.
  • Apply sheetmetal knowledge to build Box assembly.

• Flow chart for Box assembly:-

1. Construct the base feature.
2. Adding Flanges to the base TAB
3. Apply closed corner at bottom flanges
4. Adding supporting flanges for Hemming operation.
5. Hemming operation
   
   • Open closed Hem flange at two supporting flanges to joint the sheet metal rigidly.
6. Draw sketch for Dimple feature.
   • Dimple feature done at the side wall of the box assembly. This provides the extra strength and stiffness for the assembly.
   • One more dimple at the bottom face for the strengthing purpose.
7. Mirrior tools: Use the mirror tools to copy half portion of the box assembly to other side.
8. Adding Bead and Mirror
   • Bead is long, drawn-out impression, which is impressed to increase stiffness in metal sheet or plates. Depending on the workpiece size and material thickness, the ratio of length, width and imprint depth must be adjusted to obtain the maximum strenghening effect. create the one bead and mirror 3 using the coordinates the system.
9. Box Closure: - for creating the box, new datum plane is created by offsetting upto the height of the box. Create the sketch as per box profile and then base tab is created with the thickness of 2 mm.
10. Create Hing with using the different features( Flange, Open Hem, Normal cutout, Unbend, rebend)
