Casing Design

TITLE: Advance sheet metal design of CASING

OBJECTIVE: To design a sheet metal model of the casing using the NX CAD tool.

INTRODUCTION:

              Sheet metal is metal formed by an industrial process into thin, flat pieces. Actually, it is one of the fundamental forms used in metalworking, and it can be cut, bent 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 uses, some important sheet metals include silver, gold, Platinum.

        Sheet metal is generally used in automobiles, airplane fuselages, wings, and also in utensils. 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 tools 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, SOLID WORKS, PROE, etc.

I have chosen the NX CAD of SIEMENS to design this CASING part.

DESCRIPTION:

FEATURES USED:

• SKETCH: This is used to create a basic sketch of the design on selecting the desired plane, then later it can be modeled for the requirement.

• TAB: This feature is used to create a base tab on selecting the curve drawn in sketch mode with the appropriate thickness on our desire and it can easily convert that sketch into the sheet.

• NORMAL CUTOUT: This feature is used to cut the portions of the sheet metal by assigning sketch curves.

• BEND: This feature is used to bend the sheet metal along the sketched curve upon our requirement.

• FLANGE: Flange is used to add flanges on selecting the edges of our sheet metal, it is working as a BEND feature along with that extra material can be added by adjusting the length of the flange.

• BREAK CORNERS: Break corners are used to make the edges round for easy handling when using.

• UNBEND: Unbend is a feature used to analyze the model whether a part was perfectly assigned the features, which ensures for a modeler to do further operations on it.

• HOLE: It is actually used for making the holes on the requirement for further assembly of the part by assigning different types of specifications of screws.

• DIMPLE: It is used to draw a dimple on selecting a curve for modeling the sheet.

• BEADS: This feature is used to create a bead on the sheet which generally strengthens it.

• MIRROR: It is used to add the material or feature replicates by acting as a mirror to it, this generally reduces the modeling time.

• REBEND: This is used to re-bend the object after all conformations and ready for production.

• DRAFTING: It is used to provide the dimensions and views of the designed part to the manufacturing team.

CONCLUSION:

      Gained knowledge about sheet metal and its applications. All the basic features of NX CAD are practiced and finished the challenge by designing CASING DESIGN in NX CAD.
