Emkay Group was founded in the year 1978 with the vision of bringing a new

dimension to the two business sectors; automotive, & distillery. Headquartered in New

Delhi. In Ludhiana (2 units), Nashik (2 units), Haridwar, Pant Nagar, Indore, Gurgaon

and Latur (Sakole).

MY ROLE

trained in the research and development of emkay automobiles. My work was to construct and understand the sheet metal components. My work was to model the tools in 3D- software.

DESIGN APPROACH/CONSTRAINTS

CONCEPT DEVELOPMENTConcept development is the basic force behind the particular design and development. It is based on various factors-

Customer requirements- These are specifications demanded by the customer which are most necessary for us.

Technology requirements- Sometimes there are technology constraints in the way of designing of a component , so we have to go some other way by making some changes in the design process.

Economic considerations- Economic considerations are related to cost constraints .we have to complete a project under some allotted resources.

2D & 3D MODELING OF PARTS AND REQUIRED SOFTWARE

Modeling give us an idea and outlook of the features of componentsDesigner forms an opinion about the set of operation that are required for the development of the part Formation of different toolsSOFTWARES- Solid works, NX6, Autocad, Dwg editor

PROTOTYPING PROTOTYPING here refers to the

manufacturing of parts with the help

of manufacturing machines like

Computer numerical control, direct

numerical control, wire cut etc.

Drilling machines for the holes from

2mm to 50 mm dia.

BLANKING

The success of other operation is

totally depends on the accuracy of the

size of blank. Blank size is

determined by a software called

BLANK WORKS but that does not

give the exact size of blank so HIT

and TRAIL method is used to get

down to the actual size.

2D DRAWING FOR WIRE CUT

Wire cut is machine which can only read 2d data. The problem is overlapping of

multiple lines due to such geometry of component. Overlapping force the

designer to remake the whole geometry again.

FINALISATION OF LAYOUT W. R. T RAW MATERIAL YIELD

This ensures the optimized use of material. As the standard length of sheet is 1250mm so we have to convert that sheet into max. no. of blanks. As this will reduce the cost of manufacturing.SRTIP LAYOUT AND BLANKS OF DIFFERENT PARTS

BENDINGBENDING is performed to get desired

curves on the component and also

making out of plane geometries. .

Bending deform the component

making it weaker at some sections and

also decreasing the size of blank

1. Cracking due to drawing

2. Deformation of holes

3. Displacement of internal geometry

4. Wrinkling

PUNCHING

punch to be created

we all know use to make holes or any kind of shapes through the body. Punching demands high level of accuracies because any deviation in hole can lead to the failure of component and leads to scrap

WELDING FIXTURES

- A fixture is a work-holding or

support device used in the

manufacturing industry. What makes

a fixture unique is that each one is

built to fit a particular part or shape.

The main purpose of a fixture is to

locate and in some cases hold a

workpiece during either a welding

operation

RELATION GAUGES

Rec. gauges are tools which are used for the fast inspection of component. this make sure that defected goods should not passes to next stage

SOFT ANNEALING (850-650)C STRESS-RELIEVING (650-500)C HARDENING Preheating temperature:

1110–1290°F (650–750°C). Austenitizing temperature: 1810–1920°F (990–

1050°C) but usually 1830–1905°F (1000–1040°C).
