Prof. Uday Amonkar ----- An Unsung Hero of Engineering Education

I still remember those days in the Goa Engineering College hostel. I was in my Third year B.E

then. Till late nineties, Goa Engineering College was the only college available in Goa for the degree

aspirants that time. Studying in the Hostel had a different style of its own. You stroll the entire day

and sit to study in the depths of the night as if the knowledge Gods were freely distributing their

blessings on the students in the nights. Sharing what you gather from wide variety of books with

others made everyone wise.

Every night in the Hostel one Common man was seen, average personality, didn’t seem to use a

razor for shaving, his eyes covered with thick glasses, He was a great thinker and analyser. He was

indeed that Knowledge God coming as a savior to the students. He was none other than Prof. Uday

Amonkar. Anybody having any doubts in any of the subjects of Engineering, Amonkar sir was there

to help him. Scholars and intellectuals used to search him out for advice. Our studies were under

the banner of University of Bombay and our papers were set by reputed teachers from VJTI and

SPCE colleges. It was a tough task to even understand the questions, forget about answering them.

Shri Uday Amonkar had joined teaching profession soon after passing his B.E. with a clear intention

of pursuing his post graduation studies in Industrial Engineering. But like a Good Samaritan, he used

to devote his time and experience with the prospective engineers.

My tryst with Sir came though a funny incident. Happenings were round the corner in the month

of January 1988. We the gangs of Bardezkars were sitting in our room after having feast in the

hostel mess. All of a sudden a strange person in his early twenties entered our room. He introduced

himself and later on told us that tomorrow onwards he will be taking us lectures in the elective

subject. We all were surprised as no college or university professor would have introduced himself

to his students in this manner. Uday sir was like that, simple, uncanny and unconventional. There

was no ego, there was no pride, always thought of his students and his studies. I could see his

devotion even while teaching a subject of less importance in comparison to the core Mechanical

Engineering stream subjects.

One day, I just asked him one personal question, only because he was more than a friend,

philosopher and a guide to me. I told him one girl is frantically following me, she doesn’t seem to

leave me. She follows me wherever I go. Sir laughed and said she must be beautiful like you. What

beauty, she is nowhere compared to me, I said to myself. Reading my face, sir said I will ask you

one simple question you reply that question properly. I will give one utensil of gold but it is filled

inside with cow dung and I will give you another utensil which is made of cow dung but is filled with

gold. Which utensil you will prefer? Before giving the reply I could realise what sir wanted me to

realise. I knew my ego level was high when I thought about that girl. The question made me

understand the reality of life and even influenced my decisions in life.

Now, even after the good old days of studies and books and the golden years at Farmagudi, as I

entered the world of work, 3 years in Industry and later on I too joined teaching field, I could garner

inspiration from Amonkar sir on many occasions when we used to come across each other on

numerous occasions for seminars, symposiums and conferences. When in industry, I tried to pursue


4

my higher studies when sir gave me confidence how to achieve it amidst busy schedule. I failed to

stick to ME and the Industry job as it offered less perks and it used to keep my purse always empty.

Today, after putting in 22 years of service in teaching, I have seen so many professors who come

with high qualifications but work for their own self. In this IT age where information is available to

students on one finger touch, many of the teachers use multimedia like OHP, LCD, tablets & laptops

to teach the students but never correlate with student’s mental & emotional level. Amonkar sir

never did that. He created his own multimedia lessons through relentless striving. He made these

CDs & DVDs available to his students of Masters in Industrial Engineering, so that they should not

loose touch with the essence of knowledge. He used chalk & talk method to the best possible

advantage.

In his personal life and on the health front, he faced lot of hardships. He did not enjoy a very

good health, but despite odds he was a classic example of courage and dedication to duty. He

began his routine day at work at 9 am in the morning and continued till 10 pm in the night teaching

BE and ME students with equal gusto and devotion. Whenever and wherever he met his students,

his sessions used to start there, maybe it is library, canteen, and roadside shade or even in a car. At

times he used to postpone his appointments with the doctor since he had viva-voice scheduled for

the students.

Master programme in Industrial Engineering was his forte and he excelled in the same

exceedingly well. Though, I was not a student of M.E. in Industrial Engineering (which I consider my

misfortune as I missed Amonkar sir’s blessing as a guide), I have gathered lot from my colleagues

who did and were doing ME in Industrial Engineering under his stewardship. With his uniqueness

he had carved a niche for himself and the ME programme to the extent that M.E. in Industrial

Engineering had become synonymous with Prof. Uday Amonkar.

All was well until that evening of 21st Janaury 2013, when I received a SMS informing his death at

GMC in the evening, I was shell shocked. He was admitted for difficulty in breathing 2 days ago. He

only leaved his half life. For the 50% life you leaved you gave 100% to your work and your love for

teaching. They say those who die young are liked by God. It was very true in your case. Sir you have

not died but lived forever in our hearts. We will miss you and probably may not find a professor like

you for many years to come. May your beloved wife and daughter get the courage to carry on your

good work. God bless your soul.

Mr. Sunil T. Shetye, Alumni.

Field Visit: NETZSCH PUMPS AND SYSTEMS, Verna

Date : 27th Feb 2012 Timing: 9.30 am to 1.00 pm

Visiting Students : TE Mechanical (67 students)

Faculty : Prof. Sagar Kamat & Prof. Manjil Kale, Assistant Professor

Students in front of NETZSCH pumps Manufacturing Facility

NETZSCH pumps and systems is a German company that manufactures Progressing Cavity Pumps

and Rotary Lobe Pumps for the South Asian Markets from the latest manufacturing facility at Verna

Industrial Estate- Goa, India. The students were given a guided tour of the plant, where they

witnessed activities spanning various domains such as Inventory control, manufacturing, storage,

assembly, testing and dispatch. The students got an opportunity to see various CNC machining

operations, surface treatment processes, and manual assembly operations in action. Some of the

special machines which they got to see were the 3-axis HNC and VNC, the special lathe used for

manufacturing of the lobe drivers for the pumps. Various quality and production monitoring

systems were also in place. Students also got an insight into efficient plant layout techniques in use

in the industry. To summarize, the visit gave the students the opportunity to see how the theory

studied in the classroom translates to practices in the industry.

Field Visit: ASTRA METALS, Verna Date : 27th Feb 2012 Timing: 9.30 am to 1.00 pm

Visiting Students: SE Mechanical (67 students)

Faculty : Prof. Tanay Rege & Prof. Pratik Sawardekar , Assistant Professor

We, the students of SE mechanical class were taken to Astra Metal Works, Verna for our

industrial field visit. It is a fabrications company that primarily deals with the production of

precision sheet metal components and assemblies. These products are totally custom made in

accordance with the customer’s specifications.

When we arrived at the location, we were greeted by the manager Mr Rohit who also

guided us through the site and explained and demonstrated in detail the various processes that

were carried out.

The first operation that was demonstrated was the punching operation. This was done on a CNC

operated machine on which punches of the required dimensions were mounted. These punches

were spring loaded so as to absorb the shocks of the impacts when the punches were hydraulically

driven through the sheet metal. The springs protected the machines from incurring any damage.

This machine is largely automated, except the positioning, which is required to be done manually.

The job requires only 2 employees which makes it very efficient. The rest of the operation is

controlled by a computer, to which data has to be input in the form of g-codes. The data must

consist of the thickness of the sheet, dimensions of the hole, sequence in which the punching has to

be carried out. The maximum amount of load the machine could handle was about 30 tons and

sheets which were 4 cms thick could be worked on.

The second operation was the laser cutting operation. Again a CNC machine was used that

employed an oxygen- gas based laser. The laser beam was cumulated to a very fine one. The laser

torch (liquid cooled) could be moved along the y and z axis (sideways and up-down) whereas the

sheet metal has to be moved along the x axis. The metal sheet was operated on a platform which

had rollers on it to facilitate the movement of the sheet. The thickness of metal that could be cut


7

was about 8 cms. Any dimension desired can be cut out. The machine was again controlled by

computer which required the data in the form of g-codes.

Next, we were shown the bending operation. The machine was again a CNC machine that

was hydraulically powered. It had 2 jaws, the upper jaw was fixed and the lower jaw was kept

movable for convenience. The g-code now commanded the machine to bend the sheet at a

required angle, and also maintain a required flange, etc. employees were required only to support

the sheet from bending unnecessarily on account of its weight. The jaws spanned 3 mts across.

The computer that monitored this machine had a memory so that a series of sheets that

required the same amount of bending could be worked on, without the need of entering the g-

codes over and over again. It also facilitated the sequence in which a series of bending operations

with different data could be carried out. So G-codes of about 20 ops could be feed at once and then

worked on. There was also a miniature machine of the type described above. This one however was

manually operated, was one Mt long and had no computer controlling it. Small jobs could be done

on this machine. The whole idea of using automated machines was to just ensure accuracy. The

customers place their orders in the form of a CAD model or hand drawing with proper dimensions.

In the former case the CAD model can be directly converted into a form that the machine

understands, that along with the g-code has to be entered during operation. In the latter case some

of the employees constructed a CAD model out of a drawing and the rest of the process is as above.

Then the next operation was the welding operation. ASTRA METALS preferred MIG type

welding for their product as it was less expensive and the welds were strong and free of impurities.

The process is almost the same as arc welding. Only that the consumable electrode is copper which

is wound on a reel that is driven by a motor. And inert gas flows through the torch to prevent

oxidation of the weld. The operation however demands skilled and experienced employees. The

finishing was done by hand grinders.

The next step: tank treatment. This treatment removed surface impurities and readied it for

coating. It is a 9 step process. The jobs are supposed to be kept in a sieve that is mounted on a

crane. And the crane dips this sieve in different tanks. The first dip is for degreasing purposes and

uses gardoclean 444 for that purpose. The second dip simply rinses the sheets clean. The third

the surface and the 4th tank rinsed it. The 6th tank process used gardalene 21 which

neutralises the surface and the 7th rinses it again. The 8th process was for triphosphating the surface

using a zinc phosphate compound and the final tank was for passivation on the metal surface. This

was done with gardolene NLD-6800. For quality purposes the chemicals are replaced periodically.

The above tank treatments are done to ready the surface for coating. The sheets are hung in

booths for coating. Provisions are made to ground the booth and hence the metal sheet. This

ensures that the powder coating, which is positively charged with respect to the sheet, will stick.

The powder is sprayed on the metal with the help of a gun. Once it is coated it is baked for 20

minutes at 200 degrees. This melts the powder and gives the surface a uniform finish. The texture

depends completely on the type of powder used. Some good quality but expensive powders give a

smooth finish with a glossy look for example. The powder that is not used in the booth is sucked in

by centrifugal pump. This pump also separates the lighter particles (<50 micron) from the heavier

ones.


8

Then finally the coated baked sheet is varnished on the areas where it is not coated to prevent

corrosion. Then it is allowed to dry and then delivered to the customers.

To summarise, we have learnt how sheet metals are cut and shaped as required using

powered automated machines, and how these parts are joined together, how the surface is readied

and coated, all on the industrial scale.In this field visit we have learnt a lot of new things about

industry and metal works in a very enjoyable way.

TORQUE - 2013

Report by M. AGNEL XAVIER FERNANDO (BE Mech )

The Mechanical Engineering Students’ Association of Goa College of Engineering(GEC), Farmagudi,

Ponda organised their annual two day national level technical festival “TORQUE 2013” on the 14th and 15th

of March 2013 in the college campus. TORQUE was held for the fourth successive time in the college. Over

the years it has grown bigger and better with students coming not only from GEC but also from other

colleges in and outside Goa to participate and witness the event.

The event started with an inaugural function on 14th March 2013. The Chief Guest for the inaugural

function was Shri. Vivek Kamat, Director of Technical Education, Goa. The other dignitaries included Prof. R.

B. Lohani, Principal GEC, Prof. Rajesh Prabhugaonkar, Head of the Mechanical Engineering Department, GEC,

Prof. Milind Sakhardande, Staff Advisor of the MESA Council, GEC and other teaching and non-teaching staffs

from the Mechanical Engineering Department and faculties from other Departments. A large number of

students attended the function. The function started with the declaring of Torque 2013 open by the Chief

Guest Shri. Vivek Kamat. -This was followed by the garlanding of the portrait of ex-HOD of the Mechanical

Department Late.Prof.Uday Amonkar. Thereafter the specially designed TORQUE 2013 t-shirts were

launched at the hands of the chief guest and the Principal.

The Chief Guest while addressing the gathering stressed that a national level event like TORQUE

provides a platform for the young minds in the different engineering colleges and gives them an opportunity

to think out of the box. He wished good luck to torque 2013 and also started the proceedings by trying out

the Robo control.

The two day festival included events divided into two categories – Technical and Techno-Fun. The

major attraction in the Technical category was RoboWars. As the name suggests it was a fight between

robots on the specially designed arena. In this event, students had to build a robot on which were attached

the weapons. There were three rounds in total and each match had three robots fighting at a time. About 40

teams from GEC and other colleges from Goa and outside the state participated in the event. The

enthusiasm from the audience gathered around the arena added more fun to the event. As each robot hit

the opponent the claps and cheers from the crowd made it an even more exciting contest. Tyres came off,

Motors got burnt but still the war continued. Not just the make of the robot, the technique also mattered.

RoboRace was an event in which the students had to complete the lap on the track made for the

event using the robot built by them for the same. This time it was an all terrain race which included

obstacles in the form of stones, leaves, sand and oil. The criterion for judgement was the least time taken

for completing the track. About 10 teams from various colleges participated in the event. The way the robots

were controlled on the slopes, bridges and over the obstacles was amazing. There was another event called

as Catapult. The aim of the event was to test how precisely a participant can give an impulse to the ball so

that it hits the given target accurately. For giving the impulse the participant had to build a launcher for

launching the ball. The event tested the knowledge of projectile motion. Event saw healthy participation

from the students.

Line Follower was another event in the technical category wherein the robot that was constructed

by the students had to trace a black line. The robot was programmed by the students to perform the

intended function. The criterion for judgement was least time taken to cover the entire line follower track.


15

The next in line in the technical category was Amphibian. As the name suggests, in this event

students had to build a robot that could go both- on land and water. The robot had to cover the track that

was constructed for the purpose. The entire track had some portion on land and some in water.

The next category was the Techno-Fun. This category too included many events. RoboControl was

an event in which a participant had to drive the robot constructed by the torque team on a track that was

designed for the purpose. The person to complete the track in the least possible time was adjudged the

winner at the end. The event drew many participants who were very excited to control the bot and drive it

to the finish line crossing over the obstacles in the path.

An interesting event introduced in Torque 2013 was ROBOFOOTBALL. Here 4 robots in a team of

two designed by the organisers played a game of football in the specially designed arena. These robots were

controlled by the participants. The team that nets the maximum number of goals was adjudged the winner

of every match as is the case with football. The event saw wide range participation from students within the

college and outside. There was a large crowd of students around the arena who were cheering and clapping

as each team tried to net the ball in the opponent’s goal. There was an event called as Touch-Me-Not

wherein the participant had to pass an l looped metal wire from one end of a thick wire to another without

touching the wire.

Other events included Paper Presentation wherein students from various colleges presented their

ideas in the form of a paper. There was no restriction on the branch to which the students belongs to. As a

result of which there were many participants from outside the state also. There was aptitude test also which

tested the students’ logical reasoning skills. This event drew wide participation from the students who

eagerly came forward to get their skills tested. An event called psychometric test was also introduced for

the first time in Torque 2013.There were Quiz, Auction Ville wherein the students had to squeeze their

brains to get the answers right.

One of the major crowd pulling event was the AIR SHOW that was held on 14th March 2013 for the

first time in Goa by trained professionals from Pune. A total of 15 planes were flown. The students were in

for a treat as the acrobats shown were of real high class and a delight to watch. The air show lasted for

almost one and a half hour. At the end of the session the students gathered at the ground looked satisfied

and mesmerized having witnessed something really new and awesome. It was an additional boost for

Torque 2013. Another event introduced in Torque 2013 was the Military Simulation, MilSim in short that

was held on 15th March 2013. It was nothing other than the real time military simulation game wherein

twelve participants divided into two teams of six each fought a battle in the arena made for the event. The

safety of the participants and spectators was of prime importance. The participants were provided with

special suits to protect their body and eyes from the paint balls. A net was provided all around the arena for

protecting the spectators from getting hit by the paint balls. The participants said that it was a very exciting

event n similar was the response from the spectators.

The overall response from the participants and the spectators about Torque 2013 was very positive.

Torque 2013 took Torque to the next level.

Undoubtedly Torque 2013 was highly successful..

Wishing good luck for Torque in the years to come.

was designed and built locally by the students, using a large

tin lined with concrete. It had two holes, one through which

air was supplied via an old vacuum cleaner, and the other

through which molten metal was to flow out. Wood was

used as fuel to melt the metal. The casting was obtained

with substantial defects due to inexperience and improper

conditions.

KEYBOARD - A MUSICAL INSTRUMENT

M. Agnel Xavier Fernando

A keyboard is an electronic or digital musical instrument. The major components of a typical

modern electronic keyboard are:

Musical keyboard: The plastic white and black piano-style keys which the player presses, thus

connecting the switches, which triggers the electronic note or other sound. Most keyboards use a

keyboard matrix circuit to reduce the amount of wiring that is needed. It has user interface

software.

Rhythm & chord generator: A software program which produces rhythms and chords by the means

of “MIDI” electronic commands.

Sound generator: An electronic sound module typically contained within an integrated circuit or

chip, which is capable of accepting “MIDI” commands and producing sounds.

Amplifier and speaker: a low-powered audio amplifier and a small speaker that amplify the sounds

so that the listener can hear them.

Everyone has some talent. I had an interest in music right from a very young age. My parents

recognised my talent in music and encouraged me to develop it in life. I thank them and also thank

my music teachers.

I love composing new tunes and also reproducing the filmy tunes after hearing them. It is also an

excellent hobby as it helps in refreshing my mind whenever I am stressed out and tired. It played an

important part during my school days as I won many awards and prizes because of music.

I love music and more than anything else I love my keyboard (YAMAHA PSR 78) which is there with

me for the past 14 years. It is like my younger brother and my best friend at home.

Photography by Roshabh Mayekar

I bought my first digital SLR in 2010 and started to "snap"

photos. I learnt photography from ace photographers Ashish

Parmar, A.B. Apana & Assavari Kulkarni. Since then I have

been on a wonderful journey exploring my creative side. Due

to my engineering studies, I don't have as much time to

devote to photography as I would like, but I still get to spend

a lot of time on it. So I guess you can say my career as a

photographer is just beginning. I have taken maybe 10000

photos since 2010.Due to my strong technical background I understand most facets of optics and

sensors. I can use this knowledge to get the most out of any situation. This gives me the advantage

to focus more on the creative side of photography, which I have been trying to improve during the

last year or so.

Some tips on wildlife photography Wildlife subjects can be divided into two categories: wild and under human control. Pursuing both can produce wonderful images. Of course, there's nothing more exciting than capturing a spectacular image of a wild animal in its natural environment, but many times it's not possible to travel to exotic locations or spend days or weeks tracking an animal. What's more, many animals are extremely dangerous. How to Shoot Wildlife Photography: Close-up vs. Environmental

It's not necessarily desirable to always get full-frame head shots of wildlife - you can always take

head shots in a zoo. Including the environment along with an animal gives a sense of place, and if

the location happens to be spectacular then it becomes an integral part of the composition. Still,

the subject should be significant enough in the frame to make a statement.

How to Shoot Wildlife Photography the Right Way: Keep Things Steady

In addition to doing your wildlife photography in the best light, I strongly suggest using a tripod

whenever possible. When photographing with a tripod is not possible, use a bean bag or some

other stable support. Image stabilization lenses, if you can afford them, go a long way to helping

wildlife photographers get sharp pictures in low light. They minimize camera movement when you

hand hold them, which in turn gives you more flexibility in your shooting. However, I would still

recommend a tripod when it's feasible.

How to Shoot Wildlife Photography from a Vehicle

In many cases, a vehicle can gain a closer approach to a wild animal than a person can on foot. For

example, most wildlife in national parks have grown accustomed to vehicles, and they know there's

no threat. Shooting from a vehicle can be done using a stable platform that attaches firmly to the

driver's door when the window is rolled down. You can also use a burlap or fabric pouch filled with

uncooked rice, beans or coarse sand. This actually is my preferred choice for shooting from a

vehicle. I travel with it empty, but when I arrive at the shooting destination I'll fill it.

“ L I F E ” by M. Agnel Xavier Fernando, BE Mech Life is a race, which all don’t complete,

Whatever be the case, fearlessly you should compete,

You may win or you may lose, but never give up,

Face the toughest of challenges by just showing a thumbs-up.

No and impossible are the words often used by cowards,

Why to worry if you have real good friends,

With full guts and will, face the challenges,

Don’t think much about what would be the consequences.

You may fail, but remember it’s a step towards success,

Get up and march ahead, with renewed energy and confidence,

If you work hard, the result will never be fruitless,

Concentrate about the present without thinking much about the past and future.

Lend a helping hand for someone who is in need,

Because it’s nice to travel with someone in this journey of life,

Try to bring a smile to someone’s face,

It will give you immense happiness and a reason to smile.

Respecting others is something you should never forget,

Only if you know to respect, the similar respect you will get,

Enjoy your life, don’t worry just be happy, my best wishes for your future buddy...!!!
