Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly
1. TITLE : Modeling of BOX ASSEMBLY using NX CAD Sheet metal
2. Objective : Draw Casing in NX CAD using Sheet Metal workbench and list the procedure like tools used to create BOX ASSEMBLY
3. Introduction : A Sheet Metal is a engineering raw material which is used to make car bodies, aircraft bodies, food beverages tins, etc. if the thickness of the sheet is less than 6 mm then it is called as sheet metal on the other hand if the thickness of the sheet is greater than 6 mm then it is called as metal plank. These sheets have to undergo various operations to get in to a requires shape , these shapes have to pre designed in drawing sheet by designer which will be a blueprint for the production department,
The blueprint can be made by manually or conventional method or we can give the blueprint in a soft copy by using CAD tools.
In this project we are using NX CAD version 12, Sheet Metal Design to draft a casing. NX CAD is software with various work benches in it , this software is developed by SIEMENS company

Explanation of Tools
1.Sketch: it is a tab in which we can create 2D sketches and give the required dimensions by incorporating different geometrical shapes like rectangle , line, curve, circle etc, this 2D sketch is used for the 3D developments by using Tab option
2.Tab: creates a base feature by extruding a sketch along a vector by a thickness value or adds a material to a plane face
3.Flange : Adds a flange to an angle to a planar face and adds a bend between the two
4. Closed Corner : Used to close a corners where two adjacent flanges meet by extending the bends and flanges
5. Hem Flange : It is used to modify the model by folding the edge of a flange. The main purpose of this feature is to increase the stiffness and safe handling.
6. Mirror Body : This feature is used to make a copy of the half sketch or solid body along any axis
7. Unite : This feature is used to unite the mirrored bodies to make it as a single body
8.Dimple :this command lifts an area of the model inside a sketch that simulates stamping a tool.
9.Bead : Lifts a material along a counter of sketch that simulates stamping a tool
10.Undbend : It makes the part unbend that all the features done are made flat. This is useful while sketching on the corners and bends
11.Cut Out : it is used to create a pocket in desired shape, one can remove material by sketching the shape on the solid body and using this Cut Out tab
12.ReBend : This command puts back all the bends already created also along with a new feature includes while in unbent state
13.Drafting : it is the blueprint which is submitted to the production department , this drawing have all the necessary dimensions along with tolerances if any and it will be in 2D drafting
