BACKGROUNDMETAL AND ENGEENERING COOPERATION AKAKI BASIC METAL INDUSTRY

ABMI (Akaki basic metal industry) is one of among the defense industries which was established manufacturing spare parts and hand tools. Previously the industry was named as akaki spare part and hand tools social corporation

..

and producing a larger quantity of hand tools like hammer, shower, roller and etc . For the future the company is planning to produce spare parts in order to stop importing most spare parts. The industry is planning to build machines besides manufacturing spare parts in order to save large amount of foreign currency. The industry is currently doing expansion work in the manufacturing quantity and quality of machines to develop the manufacturing process. Currently plane to supply row material for Ethiopian millennium dam project.

Akaki basic metal industry is located in south east of addis abeba in akaki town it far away 25 km from addis abeba. akaki basic metal industry is one of the important industry in Etiopia. It was established in 1989 EC the factory built in cooperation with the government of the republic of italic was inautgurated by comrade MENGISTU HAILEMARIAM and general sector of the PDRE and commander in chief of revolutionary army force. The company was called akaki spare part and hand tools social cooperation

The spare part factory project being implemented within the firm work of the economical scientific and technical cooperation between the government of socialistic Ethiopia and the government of Italy

There are 10 main departments in this manufacturing factory.

DESIGN DEPARTMENT PRODUCTION PLANNING AND CONTROL DEPARTMENT MACHINE SHOP QUALITY CONTROL DEPARTMENT CUTTER STORE HEAT TREATMENT(common for all manufacturing factories) FINISHED PRODUCT WARE HOUSE WATER TREATMENT AND PUMP STATION SCRAP AND FOUNDARY RAW MATERIAL FORGING AND HEATCOMPRESSOR STATION

LATHE SECTION

This section Contains a large no of lathes which serves for functions like facing, turning, threading, parting, knurling, grooving (internal and external), chamfering, and tapering e.t.c…

 

Lathes contain five main parts Head stock

This part contains the attachments (chuck, face plate…) and the internal parts Tail stock

The tail stock serves two functions, one is to find the center point of a work piece and the other is to hold a cutter in drilling operation.

      Carriage

The carriage contains the tool post which can move in right to left as well as in the to and fro direction. The tool post contains the cutter and can be rotated at an angle.

Bed The bed carries the tool post and the tail stock.

Lead screw Lathes are specified by

Length from lathe stock to tail stock The size of the diameter of the work piece that can be hold Length of the bed

FACING TURNING THREADING PARTING BORING CHAMFERING TAPERING KNURLING

DESIGN DEPARTMENT

In this department redesigning of job orders is done by draft man and engineers. The professionals in this section use the soft wares, TO redraw the job order by taking the dimensions from the actual object.

After the drawings are done they will be arranged in “A4” format with its views and isometric drawing to express the drawing as much as possible. This finished drawing will be sent to the head of this department for checking and approval .After this step the engineers write a technological procedure for the finished drawing

QUALITY CONTROL DEPARTEMENT

The main task of this department is to check the measurements of the job according to the dimensions given on the drawings. Sometimes jobs can pass through two or more machines (e.g. lathe, milling, grinding …e.t.c),so when jobs are passed from one machine to other they will be taken to the quality section for measurement weather they are done in the required dimension or are left with the proper clearance for further operation.

If the objects are far from the dimension given in the drawing then the department will reject the piece. This department uses several types of instruments for measurements and evaluation

MACHINE SHOP

The conventional machine shop contains three different types of machine shops and one cutter store.

LATHE MACHINE SHOP MILLING MACHINE SHOP HEAVY DUTY MACHINE SHOP CUTTER STORE PLANER AND SHAPER WORK SHOP

CUTTER STORE

The cutter store contains a large number of cutters for the different machines in

the manufacturing factory. End mill Jig boring Slotting cutter Module Concave and convex cutter Shell cutter Face milling carbide

The benefits I have gained from working in ABMI

I can say that I have improved my previous skills and I even developed new practical skills that, I hardly had practical and theoretical exposure before I entered in to ABMI . So, I can say full-hearted that this intern program has shown me how to handle some practical aspects of technical terms.

I may not be able to explain all of them in here but I have tried to mention some of them as follows:-

I can say that I improved my welding capacity. I know how to cut materials using different

kinds of grinders and cutters. I develop the skill of working in noisy work shop. I learned how the school documentation is

necessary in the working area. I improve how replace different kind of gear to

machine. I have developed different kinds of pattern how

to did

The kind of challenges I have faced in ABMI

I have encountered with different kinds of obstacles and challenges in my first work expedition. These challenges have left me with life time lessons which have taught me many great things. So, I am very much honored to say that these were not problems rather they were worth telling experiences.

I have scrawled down some of the very points below:- At least no mechanical engineer in the technical staff. There is lack of well trained human resource. So most of

the work is accomplished through the medium of experience which intern does not give comfort.

The measures I have taken in order to win these challenges

I believe in something in my nature that is” if things go in other way around do nothing just stay still until you conceive the core of the problem to dry it up from its grass root.” So this thing has worked out for me and it has even made the passage way very easy. So, I was not troubled to make friends in a very short period of time. In general what I have done was I have tried to buy some time to connect myself to the working principles of the industry.

Comment

I have tried to suggest some crucial points that help the company at large. For this report I have included only the suggestion that.

I took in industry air conditioning, scrape material wastage, pattern Lack of Human safety, power sand and dust separator lack of instrument water treatment

RECOMMENDATION

From the time I spent in the industry we identify not only things that enhance the manufacturing process but also things that are defects for the manufacturing process.

Lack of enough cutters enforces the machinists to borrow, spending the production time. A cutter collection should be placed for each machinist.

Using the same machine in the two shifts cause the work quality to deteriorate kills the machinists time since they spend many hours to dismantle others attachments and place their own.

Lack of means to reuse the rejected pieces and chips causes the company to lose large amount of money. Reusing the left over’s by melting and making them functional for application which doesn’t require material property such as in medals and badges manufacturing and gift articles manufacturing.

Air conditioning system is necessary since create a suitable work environment prepares the worker for a better performance in their jobs.

The industry is performing only based on customer order, but to take it to the next level the industry should have to conduct a market research and should have to produce by making itself competitive in the market.

Conclusion

While I sum up my report I would love to say or write down some very crucial points . I was perplexed by the whole idea of internship from the day I have heard it exists to the day I began to work for the last consecutive four months. In general I could say that I had vague attitude I even wished many times if it does not ever exists. But now I can tell that it has both an advantage and disadvantage .well this can be briefly seen as follow .if one industry which cannot afford highly paid experts can use this opportunity to fill up some of their vacant spaces. At this time we do not have to forget that the student is benefited as well since he/she has got practical exposure.

As disadvantage i can put for forward one simple instance which has many implications. The university has to be in position to state directions which are uniform for all companies as to how this company accept and host these students. If this is not met by the respective universities the students who are assigned to different industries might be oppressed and they might be deprived some of the things they have to get. In here we can raise the case of pocket money which is not uniform. The other thing is that the company I was working in did not give us either an office or computer.

Lastly, I believe that this internship has to be continued since it has got lot of virtues.
