Objective:-To design a sheet metal box assembly in industrial manner by using siemens NX.

Introduction:-

Sheet metal is metal formed by an industrial process into thin, flat pieces. Actually, It is one of the fundamental forms used in metal working and it can be cut, bend into a variety of shapes. Countless everyday objects are fabricated from sheet metal.

Many other different metals can be made into sheet metal such as Aluminium, brass, copper, steel, tin, nickel and titanium. For decorative users, some important sheet metals include silver, gold, Platinum.

Sheet metal is generally used in automobiles, airplane fuselager, wings and also in utensls. To manufacture all these in different designs and preparing drafting in the desired way by a manual drawing cannot be performed. If we use the design tool to do this can be a better choice and helps in modeling the object can be done easily.

There are some of the design tool software are available like CATIA, AUTOCAD, NX-CAD, SOLIDWORKS, PROE etc.I have chosen the NX_CAD of siemens to design this Box Assembly.

Design Methodelogy

File Creation -A new part file is created by choosing the sheet metal in NX-CAD.
Sketching - A rectangular sketch is created by selecting the appropriate plane.
Base Feature - A base feature is created by using the TAB feature by converting sketch into sheet metal with 1mm thickness.
Adding Flanges - Add falnges of both side on opposite direction to cut out portion.
Hem Flanges - Hem Flanges in outer Edges.
Mirror Body - Mirror the body with respect to plane.
Unite - Unite the main body and mirror body.
Lid Creation - Lid Creation on the base surface.
Creat Flanges - Creat Flanges in outer portion.
Upper Hinge Creation - Create upper hinge.
Flat Pattern - Create flate pattern.
Drafting - Drafting should be done for the sheet.
