Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design
1. TITLE : Modeling of CASING 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 CASING
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.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
- Bend :It modifies the model by bending material on one side of a sketch line adding a bend between the two sides.
5.Flange : Adds a flange to an angle to a planar face and adds a bend between the two
6.Break Corner : this commands allows to rounding off the sharp corners
7.Undbend : It makes the part unbend that all the features done are made flat. This is useful while sketching on the corners and bends
8.Hole : his command allows user to create a hole in the part by sketching a point on the sheet metal
9.Studio Spline : it results in a set of splines after selecting the points for its path . it is used for making splines along the sketch
10.Move Curve : this tab allows the user to move or rotate the curve at reduried direction and angle
11.Dimple :this command lifts an area of the model inside a sketch that simulates stamping a tool.
12.Bead : Lifts a material along a counter of sketch that simulates stamping a tool
13.ReBend : This command puts back all the bends already created also along with a new feature includes while in unbent state
14.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
