NX_Box Assembly_Harish Patil.

Design of Box Assembly using NX sheet metal application.

Objective:
To design a Box assembly by using Siemens NX sheetmetal Application.

Introduction:
NX Siemens contains a series of applications that support different workflows, such as creating parts, building an assembly, or producing a drawing. And NX Siemens sheetmetal application provides an environment for the design of sheetmetal parts used in Machinery, Automotive industry and Aerospace etc.

Design Of Methodology:

Work flow to design a Box Assembly.

• Sketch the 2D shape of the Box Assembly.
• Construct the Base feature using tab.
• Add Flange ,Closed Corner & Hem Flange.
• Mirror body & add Unite.
• Unbend the part and add other features such as dimple, hole and beads.
• Rebend the part after applying of required features
• Create flat pattern.
• Create a drawing sheet by using of drafting.

Description:

Tools used:

1. Sketch: Used to create a 2D sketch on the plane.
   
   
2. Line: Used to draw a line.
   
   
3. Rectangle: Used to draw a rectangle.
   
   
4. Fillet: Bend the sharp edges.
   
   
5. Circle: Used to draw a circle.
   
   
6. Point: Used to create a point in the sketch.

Features Used:

1. Tab: Use to create a base feature by extruding a sketch along a vector by thickness valve or by adding material to existing faces & bend regions of sheet metal part.
   
   
2. Normal Cutout: It is used to create the cutout to the material by projecting a sketch onto the model and then cutting perpendicular to the faces intersected by the projection.
   
   
3. Bend: It is used to bend the material by projecting a sketch on the model perpendicular to the faces intersected by the projection.
   
   
4. Flange: Use to add a flat flange at an angle to a planner face & add a bend b/w the two.
   
   
5. Closed Corner: Use to modify two flanges in one operation & to close the corner where the two flanges meet.
   
   
6. Hem Flange: use to modify an edge of a sheet metal part by folding it onto itself for the purpose of safe handling or to increase edge stiffness.
   
   
7. Mirror: Use to mirror a feature or entirie body with the reference of plane.
   
   
8. Untie:Joining two bodies.
   
   
9. Break Corner: Use to round or chamfer sharp corners of a tab or flange.
   
   
10. Unbend: It is reverse of bend feature , used to add some more feature.
    
    
11. Hole: Use to create a hole in the body using standard valves.
    
    
12. Dimple: Use to lift an area of the model inside a sketch that simulates a stamping tool.
    
    
13. Bead: use to lift the material along the contour of a sketch that simulates a stamping tool.
    
    
14. Rebend: Use to gain the original position.
    
    
15. Flat Pattern: Used to create a flat pattern feature form the formed sheetmetal part.
    
    
16. Base View: Creates the model based view on the drawing sheet.

Conclusion :
Design Box Assembly using sheet metal in NX & view the drawing using drafting application.
