Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

Title: Advanced Sheet Metal Design Using NX Cad - Box Assembly

Objective: To model Box assembly using NX CAD application.

Introduction:

1. NX CAD: NX, formerly known as "unigraphics", is an advanced high-end CAD/CAM/CAE, which has been owned since 2007 by Siemens PLM Software.
   
   
2. Sheet metal: It is metal formed by an industrial process into thin, flat pieces. Sheet Metal parts are manufactured from a single sheet of metal the part must maintain a uniform wall thickness. Sheet metal parts with a minimum of 0.9mm to 20mm in thickness can be manufactured.

Design methodology:

Tools and features:

• Tab: By creating a new sketch, base is obtained with mentioned thickness of sheet metal.
  
  
• Flange: Creating a bent feature on sides of sheet metal.
  
  
• Closed corner: Creating or closing the corner of sheet.
  
  
• Hem flange: Creating flange in completely in U-direction.
  
  
• Mirror body: Mirroring the body w.r.t a reference plane.
  
  
• Unite: Combine two or more bodies into a single body.
  
  
• Dimple: An embedded feature is obtained with the help of sketch inward or outward.
  
  
• Mirror feature: Mirroring the features w.r.t a reference plane.
  
  
• Unbend: Sheet at bended surfaces is unbended.
  
  
• Rebend: Unbended surface is rebended.
  
  
• Bead: Profile is beaded for strengthening the sheet.
  
  
• Datum plane: A new plane is created w.r.t reference Datum.
  
  
• Break corner: Cutting the corner of sheet in circular manner.
  
  
• Normal cutout: Cutting the sheet of profile normally.
