Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly
Box Assembly
Objective:-To be design a Box Assembly by using NX cad.
Introduction:- We Design sheetmetal Box Assembly with the proper asumption of sheetmetal manufacturing .sheetmetal is a wiedly used in industry. It's a very cheap and easy to manufacture. It can be cut and bend into variety of shapes .we consider differnt type of sheetmetal process like blanking, punching ,Nibbling,sliting ,notching trimming, etc and also joining process of sheetmetal like TIG welding, MIG welding,Riveting etc.if we talk about automobile industries. it play a very important role 60% of component are manufacturing by the sheet metal for example:-roof hood fender ,door panel frant mud etc.
Methodology:-
1.first we take the blank size of sheet for box assembly.
Blank size formula - L1= L -(`tan (θ/2)`x(R+T)
BA1=`θ`(`π/180`)(R+KXT)
2. second we bend the sheetmetal with proper angle .
During the bending we maintain the proper bend radius and bend angle
3.Third we creat the dimple on both side by the punching process.
4.we creat the punch and supporting rib on the bottom side by bthe punching process.
5.we creat a hinges and join with the differnt joining process for holding the top cover
Tools and feature used while designig:-
1.First we creat a tab.
2.we creat a flange on both side.
3.Again we creat flange and hem for locking.
4.Then mirror the object by using merror command.
5.Then we used unite command for the joining.
6.Then we creat the dimple on the side face.
7.Then we merror feature on the other side.
8.Then we creat the dimple on the bottom side.
9.Then we creat the bead by using bead command.
10.Then we creat the tab for the to cover
11.Then we creat the tab and flange on the side face.
12.Then we creat the hem .
13.Then we creat a normal cutout.
14.Then rebend and do the mirror .
15. Then we creat a tab on the top surface.
16.Then unbend and cutout by the normal cut out command.
17. Then rebend and match the face.

CONCLUSION:-
In this we learn how we design sheetmetal box by using nx software command and also different type sheetmetal manufacturing process and joining process of sheetmetal.
