Introduction

Click to add text Welcome to all. First of all I would thanks to

you to spend little bit time to read my portfolio. “ My mind is a partner to my work” I hope that my portfolio will reflect my

stuff, power ,skills , working capability Etc…. I am DHILIP KUMAR studying

MECHANICAL Engineering in GCT college.

Introduction of my work

My work is a creative one. Because we are creating the art in a metal. Doing design in a solid works software. This is only a small part of my work.

My work starting from make a desing up to delivery. In between start to end Of the product I learn Something, like that timeManagement , If any Mistake how to solve it, Must to improve customer’s satisfaction and Quality of the product.

Utilize The Opportunity

• Our honorable Principle Mrs. LAKSMI PRABHA and our senior Mr. BALA & Mrs. Jacqueline gave me the opportunity to do this work.

That day was my memorable day because I

am not able to pay my fees. So I met my principle and she asked to me to meet Mr.Bala . After that I went to his house. He gave me an internship as well as a part time work in his company. Mr.Bala and his friend Mrs. Jacqueline fully supported me by financial also.

This one is very help to me to develop myself and my skills. I hope that I had utilized this opportunity.

STUDIES BASED PROJECTS : 1. Stationary stand 2.Trishul design and fabrication 3.Chair manufacturing 4.Ladder design 5.Elevator design WORK BASED PROJECT : 6.Singapore project 7.Chennai map project 8.Dr. A B J Abdul kalam project 9. Vengadajalapathi project

My simple Design & projects

Stationary stand

The basic aim is how to reuse the waste. “ WASTE COME GOOD AND BEST “

Source : Collect the waste glass piece in a old factory. Then the waste pieces are cut by equal size. That the basic idea is to create a hole on the glass piece. And the glass is placed in side the rod.

Specification Waste glass piece Nut ,Bolt & Waser Threaded rod – 20 ft length Stainless steel pipe -2 mm dia

Assembly : That the threaded rod is fixed inside the base then nut and bolt is used to fix the bottom end. The nut is put in to the hallow pipe and that setup is fixed shown in the figure.

Working process

Result : My first idea is a failure idea because I create only two hole on the glass piece so that the stand have low stability and made more vibration. After that study what to do then I create 3 hole on the glass piece , it may increase the stability and the strength of the product. After that it has no more vibration.

My experience: 1.Planning is important for all project. 2.Everyone should know stability. “EVERYBODY LEARN, SOMETHING ONLY FROM THEIR MISTAKES”

Thrishul design and fabrication

This project is one of the good chance to think 360 degree. This is an electrical based vehicle. It is a finished design just I am doing some modification in the design because of reducing the cost of the vehicle.

In a old design it has more welds and the assembly of part is very complicated. My motto is to reduce welds and cost also the working times. My project mates Mr.Ramadas and Mr.Karmukilan help me to do this project.

Required materials Thus the required material are given .These files are generated in DWG format by using solid work software and reference are in Pdf format. Thus the assembly parts were cutted by using “ TURRET CUTTING ”.

Assembly parts :1. Bottom piece2. Battery cover box3. Shaft4. Base flange 5. Handle bar6. Fork assembly7. Front wheel with Bobo hub motor8. Supporting back wheel

Required material for fork assembly

Drive wheel with bobo motor

Other parts :

Modifying the designWe create some modification in the design. 1) First of all we desired to increase the stability of the

bottom piece because it may broken to carry above 75 kg of weight.

2 ) To give additional support to the wheel shaft.3 ) To give proper open & closed section for battery in the form

of battery box.4 ) Battery clamp is used to arrest the battery in safe mode.5 ) And the other parts are used from old design. After that the normal assembly are done by using the

parts. My work is only make a design and assemble the parts.

That the electrical works are done by the company.

Chair design and manufacturing

This is my favorite project, Because at that time I Think this is very simple project, it has less work and do that project very less time.

But while dong this project I met more difficulties and problems. Mr.Bala gave me a little time to finish the project. The target is manufacture 100 chair within 7 days.

This is the new chance for learn something from welding and help us to know process planning and time schedule for a project.

Mr.suresh welder give a advice for planning. My project mates Karmukilan and Ramadass help me to do this work.

Construction and details: This is a steel based Chair, So we are purchased the steel pipe. Steel pipe-2 mm thickness Dia of pipe- 2mm Sitting sheet-Req amount

To create jig for chair

• That the model type of chair is give us. • After that we may create the base of the chair shown in figure. This is called as jig.• Jig is a device that is used to make a project with high accuracy.• It may reduce the work and also the time.•Increase the production of the chair.• After that go to do the required bending in the pipe.

Welding tools• It may take two days . That day was my semester holiday so, I can work with him up to start to end. • We were using these tool cutting, grinding and buffing wheel.• MIG welding machine is used to make a weld on the chair. • In this project help us to learn the basic welding and welding tools.

Learn MIG welding process At that time we have lot of work for doing chair. So, sureh welder ask me to learn MIG welding and do some full welding in the chair . The shown figure is just a triangle piece . I am doing some weld in the triangle. And give it to suresh for correction and he told me this is fine you may continue your work to do weld on the chair. So, we have two welding machine my project mates Mr.Karmukilan and Mr.Ramadass help as to did the work successfully.

Working process

Result: That the given project

is finished successfully . It may giving a new experience for us.

Learn and experience: 1. I get knowledge about

MIG welding also Arc welding

2. Also from grinding and buffing.

3. How to calculate the time for do anything.

Elevator design This is a simple project for test my software skill. Mr.Suresh told me an idea for making elevator. He is a welder. so, he got a order from Chennai in a small scale industry. It is a cloth washing company. They want simple elevator for carry wet dresses from ground floor to top floor. And I have an idea , I told to Suresh and I make a drawing in solid works.

He told that it has less work and more stability and it have low cost.So, I only use sheet metal in the form of square and rectangular bar. That the image can reflect my idea. That the elevator contains base stand and rope and a little motor for up and down moment. This is the basic model of the elevator.

Result : This is the final design. I change 3 design this is the last design. They accept that model and the same idea create new and simple elevator .

Work based project -Through metal arts

MASTER DESIGNs

Dr. A P J . Abdulkalam design This is my favorite design in my design history. Because, in my knowledge all are know who is Mr.kalam , I am one of the fan of kalam sir. While am starting the work am very impressed to do that work. Mainly two reason for my happiness. 1. That the design is placed in my college with my name. 2. Also the design is placed in Mr.Klam sir house. Both reason give me more happiness and confidence. I finished the work very quickly. After completing the drawing. Gave the drawing files in to Laser cutting and then giving it in to powder coating. This is the main idea shown in figure.

In this project design have little bit difficulties. We consider not only the design but also the base of the product. Because it has 8 feet height, so we increase the stability to give more strength at the base. First I finished the drawing. Then create the required stand for carry the design. First I create normal stand and then give the support at the backside of the image. It has low stability because It has a chance of fall down in front side. So, my next idea is giving the equal stability for front and back. After changing the ideas. First I give 2feet on both side now the main role is increase base strength. So, provide 3 feet on both side. And the top view of the stand is in “ H “ shape. That is give the more stability to the product. Specification : Height of the design = 12 ft Width = 3 ft Thickness = 2mm Rectangular bar = 13 ft

Working process

Identify the mistake

While doing the project I am in happy. But that more happiness is spoil my thinking. I make very big mistake on it because of my carelessness . I write kalam’s quotes at the bottom of his design. The quote is,

“You cannot change your FUTURE, You can change your HABITS. And surely your HABITS, Will change your FUTURE “

Recover the mistakes My mistake is putting double “B “ for HABBITS . It is a very critical time. Because I complete all work including cutting also. Tomorrow it must be delivered in kalam sir house. So, I consult with my project mates they advising me to modify the design immediately . That the idea is cut the B letter in the design and join them by using MIG welding.

Different colures of powder coating

Memorable day in my life It is the good opportunity to visit kalam sir house. After correct the mistakethat the design go to be powder well powder coated. I reach his house and present it to his brother.

After that another kalam sir design is fitted in my college. Our honorable principle giving the motivation to us. We are get a award from principal.My project mates names are written at the end of design.
