Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

NX_BOX_ASSEMBLY

OBJECTIVE : To design an advanced Box assembly using the sheet metal application in siemens NX.

Introduction

sheet metal design is a vast domain in the design of any sheet metal industry,it is used many sectors including the aeronautics & automotive sectors , in this sheet metal box assembly design we will look at the design approch using NX (CAD) SOFTWARE through various design , images , explaination and images .

Design Approach

figure 1 above shows the flow chart of the method used to achive the final design of the box assembly

Description

firstly we have to sketch the desired shapes of countinoues line then using the tab option , a desired sketch was then created on to the base tab .the flanges are created on the perviously created tab later to that desired sketch was then created on the surface of the tab (flanges are to normal to xy plane ) & flange are created on the edges of previously created flanges (flanges are to normal to xz plane ).

closed corner are added by 'closed corner command' to the corner were the two or more sheets comes and merge at a single point to form smoth and round surface & bended surface .flange with bend radius are the flanges were create a round bend to create lenght flange .

hemming with lenght reference this are option were the box it will help to lock the sheet firmly like the knot of thread locked and lateron the sheet is mirrored and united to one object to form a box and to the side & bottom of the box the dimple is created using dimple option .the bead is created on four corner of the bottom of box by using sketch as reference by bead option .

the datum plane is ofsetted to distance onto the lengnth of more than a box size create a required sketch onto the surface and add the base tab as the cover to the box ,creating a sketch to the previously mounted tab of cover of box and tab that and break the corner and make the open hem to create the rod lock it will act as rotactional lock and later its assemble

conclusion :

the design of the box assembly has certain dimension and is maintained and designed is completed
