DESIGN A POWER SUPPLY UNIT IN CPU USING NX CAD

DESIGN A POWER SUPPLY UNIT IN CPU USING NX CAD (SheetMetal):

OBJECTIVE:

• The aim of this project is to design the Power Supply Unit in CPU using NX CAD (Sheet Metal Application).

INTRODUCTION:

• NX, formerly known as "unigraphics", is an advanced high-end CAD/CAM/CAE, which has been owned by Siemens PLM Software.
• NX sheet metal design software incorporates material and process information in sheet metal-specific modeling features: bends, flanges, tabs, cutouts, beads, dimples, louvers, corner and edge treatments, patterns and other formable features. You can also quickly convert solid models to sheet metal components, and create sheet metal parts that enclose other components.

DESIGN METHODOLOGY:

• 

BLUEPRINT SETUP:

• 

DESCRIPTION:

• Software Used:
  • NX CAD
• Parts of Power Supply Unit:
  • Lower case
  • Upper Case
• Features Used:
  
  • Set Preferences:
    • Sets parameters and characterstics for Sheet Metal Commands.
  • Tab:
    • Creates a base feature by extruding a sketch along a vector by a thickness value, or adds material to a planar face.
    • Additional planar selections can be added to generate bends as part of the base feature.
  • Flange:
    • Adds a flat flange at an angle to a planar face and adds a bend between the two.
  • Dimple:
    • Lifts an area of the model inside a sketch that simulates a stamping tool.
  • Normal Cutout:
    • Cuts material by projecting a sketch onto the model and then cutting perpendicular to the faces intersected by the projection.
  • Break Corner:
    
    • Rounds or chamfers a sharp corner of a tab or flange.
  • Hole:
    • Adds a hole to one or more solid bodies in a part or assembly with options for counterbored, countersunk, and threaded.
  • Advance Flange:
    • Adds a flange along an edge using a bend angle or a reference face. The edge and reference face can be curved.
  • Closed Corner:
    • Closes a corner where two adjacent flanges meet by extending the bends and flanges.
  • Mirror Feature:
    • Copies a feature and mirrors it across a plane.
• Part Modelling:
  • Lower Case:
    • Features Used: Tab, Flange, Dimple, Normal Cutout, Hole, Advance Flange, Closed Corner, Mirror Feature.
    • Model:
      • 
  • Upper Case:
    • Features Used: Tab, Flange, Dimple, Normal Cutout,Break Corner, Hole, Advance Flange, Closed Corner, Mirror Feature.
    • Model:
      • 

ASSEMBLY:

• Assembly Constraints: Positions components in relation to other components in the assembly by specifying constraint relationships.
