Mechanical engineering at MIT is nearly as old as MIT itself, and its impact on the Institute and on society itself is easily demonstrated by noting the alignment of the department’s evolution with key events and technological advances in the world.

MechE logoMechE’s origins trace back to the end of the American Civil War, in 1865. Its earliest areas of focus included extensive programs in power engineering and steam engines for both transportation and fixed use. By the mid-1870s, with the Industrial Revolution well underway in North America, the department became known officially as Course II. It innovated the use of lab subjects, giving students the opportunity to apply methodology to current engineering problems with hands-on lab work.

The specializations offered at the time reflected the industries of greatest growth, including marine engineering, locomotive engineering, textile engineering, and naval architecture. In 1893, marine engineering spun off from MechE as its own course and remained independent until it merged back (as Ocean Science and Engineering) in 2005. By the turn of the century through the advent of World War I, programs in steam turbine engineering, engine design, refrigeration, and aeronautical engineering set the stage for the technological advances to come.

Between World War I and World War II, automotive engineering was a very popular program in MechE. The Sloan Automotive Laboratory, founded in 1929, became one of the world’s leading automotive research centers. Post-World War II, the department’s research emphasis gradually shifted from military applications (which continue to be an important component of the overall MechE program in the present day) to “quality-of-life” applications, such as biomedical engineering, energy and environment, and human services.

MechE Today

Mass, motion, forces, energy, design, and manufacturing – these comprise the world of mechanical engineering. Today, MechE attracts and features an extraordinarily rich diversity and quantity of talented individuals, including 400 undergraduates, 500 graduate students, and about 75 faculty, many of whom are members of the National Academies and fellows of prestigious professional societies.

MechE logoMechE conducts about $35 million worth of sponsored research annually, in a range of areas – such as mechanics, product design, energy, nanoengineering, ocean engineering, control, robotics, and bioengineering – that are diverse and yet also allow for rich collaboration both within the department and with other engineering and science disciplines at MIT and beyond.

These broad areas of focus and our commitment to multidisciplinary research results in an exciting variety of innovative projects, including the use of active control to optimize combustion processes; the design of miniature robots for extraterrestrial exploration; the development of unmanned underwater vehicles; the prevention of material degradation in proton-exchange membrane fuel cells; the development of physiological models for the human liver; and the fabrication of 3-D nanostructures out of 2-D substrates.

Where are the skilled Indians?

December 31st, 2009

There are two prevalent perceptions about India in the west. On the one hand, people scoff at India’s failure to reduce poverty and illiteracy in
a substantial manner even as many Asian countries have made successful strides into lowering both. On the other, there is widespread admiration, bordering on envy, about the nation’s immense pool of highly-skilled professionals who have become important players in the global economy. In the western view, there are two Indias: the Poor and Illiterate India, and India of its highly-skilled professionals.

It is the second India that is focus of this column. In the last two decades, the number of skilled Indian professionals working abroad has grown many times. Indians are the most educated ethnic group in the US and one of the richest too. A quarter of all H1B visas for professionals to work in the US are issued to Indians. Many industrialised countries like Canada, Germany, the UK, the US and Japan have been competing to attract skilled workers from India and other developing countries. India, along with other large emerging economies, has become a major source of skilled workforce for several industrialised countries.

Ironically, India does not have enough high-skilled professionals to fulfill its domestic needs. Years of brain drain may have played a tiny role in this. But the primary cause of skill shortage is the sudden surge in growth in the nation’s economy and increased investments in several sectors. Indeed, there is some evidence of the start of a reversal of brain drain in recent years as many professionals return to India after a stint abroad for better economic opportunities.

Yet, skill shortages remain acute in several areas. India may be a major source of talent for the global economy, it produces far less talent than what is required to meet the needs of its fast-expanding economy. Consider this: Indian engineering schools produce around 12,000 new civil engineers a year. The country needs at least 70,000 additional civil engineers to meet its massive infrastructure needs! Currently, Indian engineering schools produce civil engineers that meet just about a sixth of the industry’s additional needs. These shortages have become the biggest obstacle to investment in infrastructure.

Several factors explain this scarcity. During the 1990s, as the world economy was experiencing an internet boom, the demand for Indian IT engineers increased and salaries of IT professionals skyrocketed. Many were being hired by foreign companies even before they finished schooling. In response, students started opting for engineering courses in IT, communications and electronics, and the number opting for civil and mechanical engineering plummeted. Engineering colleges reacted to these changes in supply and demand by shutting down civil engineering departments and expanding or creating departments of communications, IT and electronics. Of the 1,700 engineering schools approved by the All India Council for Technical Education, only 200 offer civil engineering degrees today.

During most of the past two decades, a substantial proportion of the investment in the schools of engineering was to cater to the demand from the IT and communications industry, Indian as well as foreign. No one even considered that there would be demand resurgence in traditional fields of engineering such as mechanical or civil. Not many during the 1990s believed that the Indian economy would grow at 8-9% a year and the infrastructure sector would need to expand at 30% a year to sustain long-term growth. All this has changed with the government and the private sector investing billions in national highways, airports, railway stations, ports, commercial real estate and housing.

Mechanical engineering

Mechanical Engineering is an engineering discipline that was developed from the application of principles from physics and materials science. Mechanical engineering involves the analysis, design, manufacturing, and maintenance of various systems. It is one of the oldest and broadest engineering disciplines.

The field requires a solid understanding of core concepts including mechanics, kinematics, thermodynamics, fluid mechanics, heat transfer, materials science, and energy. Mechanical engineers use the core principles as well as other knowledge in the field to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, motor vehicles, aircraft, watercraft, robotics, medical devices and more…..

The Mechanical Ark

December 31st, 2009

I fell in love with this delightful fountain in Koblenz, Germany. I wish I knew the story behind it, as it seemed completely out of place just outside of a modernish mall exit.

Middle East is a vibrant and a fluctuating market. Period. But not for those surviving on the tether around them, confining them to their cubicles. And also, my sympathies for those who work in the Accounts and Finance departments; although Middle East is largely tax free throughtout all the seasons but accounts people suffer from most ailments one finds in the Middle East, Diabetes tops it, then Heart related. Accounts is not a romantic role, though, but nonetheless it pounces right at your heart.

After gaining a thorough 4+ years in the Middle East market, also bagging some certifications in ISO 9000:2008 for Internal Auditing and SAP; much of the experience provides me to leverage my efforts much more fruitfully for my own benefit. Job is where you agree to act like a slave. You agree to the terms and conditions of any website before registering, you don’t think twice. But before you do that in the Middle East, stop, consult, think, rethink again and rethink again. The shadowy areas are never discussed until you are cornered in your cubicles.

But, quality of service in the Middle East is always tainted and compromised. But the irony is, you’re expected to work and show yourself busy like Barack Obama. No offence meant but your boss would never commend your MIGHTY work. You would strain, stress, press, redress your efforts and resume but appreciation is an art which cannot be searched in the museums. Your boss envies it. So its out. Why..? Because your Boss is ALWAYS RIGHT..!!!

And that you don’t have a say here. No strikes, yeah, think about it and you’re aborted, deported and black listed. Now what shall we do. And yes, you can only work for one employer at a time and only that job which is mentioned onto your visa. Other than that, its illegal. Sounds Utopian right..? So what can you do?  Suffer is the first option, but that suffering brings with it its benefits. Firstly, Public relations, it is a grand big leverage to land yourself a role, perhaps a job if you’re persistent and know how to make and offer a lemonade for your to-be-boss.

Yeah that’s the trick; flatter others and you won’t find yourself lying flat in the airport lounge and flying out for good from the Middle East. Secondly, experience. Majority of the people who come here to the Middle East, are focused and poised just to EARN MONEY..!! But you won’t set your targets that perrenially retarted and puny.

You have to grow and Middle East is a growing and festering ‘hinterland’ (although it isn’t, pun intended) just for ENTREPRENEURS. So you again experience and not in one mode or area of interest, multi modal experience counts alot. Once you’re over 3 years of core and meaty experience in your and your sweet beautiful colleague’s (in the next cubicle) experience, you are ready to jump onto the next phase. And that is, community work..!! Kidding.

Next phase is where you would have amassed a bunch of newspapers (enough to fill 3 and a half warehouses, yeah the other half of the third would be vacant for the trucks to tow away the mice-nibbled and recyclable paper) and business cards already before you get down to real business. Freelancing is a better way to make your mark in the after-office hours. Abundant opportunities can be browsed through the local newspapers, get to know or hear from your peers (peers from the business cards, in short Networking helps) about upcoming developments. One can contact entities like companies and institutes to garner and utilise your abilities for a percentage. You both share. In this way, the first party (company / institute) doesn’t have to go through all the hassles to support you with the visa procedure which is like sun baking in the desert for them.

Start small and limited and you’ll get to see the wider scope. Start from the back of the pack, remember a movie is best watched and looking if you are at the last row somewhere in the middle, only action movies, mind you. Once you’re in, nothing stops you then. Neither your employer nor your urge to rush for a movie. Once the trend picks up, you would be amazed that you would be saving your whole salary and spending from your extra income. But that comes later, don’t jump and don’t be expensive. Now, you have extra money but not extra time. Outsource, sublet, get a group of friends again to divide and subdivide a mini task to mini projects.

Then again, get everything (projects, mini tasks and not mini skirts, you seem you CANNOT handle at this point as you would have quite a considerable connections and that you would earn a percentage on your networking and delegating capabilities.

From programming, web development, technical (Mechanical / Instrumental), education, financial advice (Year End support and preparation), repair and maintenance, tutoring, advice (Quality Management and Improvement, Supplies, Interior decoration, exploration, introducing (parties with each other, importer and exporter area, I love to do that) and the list goes on.

The service industry is better open after the office hours, although you might not hear the sweet voice of the secretary on the other end, who makes you to call her office for no reason. Yeah, live with it. But believe me her voice is chirpy, you don’t want to drive all the way down to see her. Reality d***s. So folks, if you’re planning to land in here anytime, make sure you have your swimsuits, goggles, a good business plan and guts to work and suffer under your illegitimate boss.

Good luck with your struggling careers..!!

Let it be made!

Here’s a little video of the machine working:

My projects doesn’t make them self, and if you want to make a project that looks nice you need some kind of machinery for the mechanical things. Thats why I build my first cnc machine, it was really a simplistic one and build of MDF wood, but it worked very well for the costs of it (less than 150 euro)! It took me about 3 months of working in my spare time. For the electronics I used the design of Tom McWire, from his instructable: http://www.instructables.com/id/Easy-to-build-CNC-Mill-Stepper-Motor-and-Driver-ci/. The electronics drive the stepper motors and the electronics are controlled by the software program “Kcam” which controls the LPT port. To make PCB’s I use Sprint layout, to generate a PCB layout and exported them to a HPGL file which I import in Kcam. The milling is done by a simple and cheap multi-tool. I was really happy I just started to build a cnc machine because at the beginning I didn’t know if it would actually work! Well it did!  I used it to engrave a lot, some milling jobs and also made some PCB’s with it:

But after a while I saw some bad points of my machine and decided to build another one, this time it was a machine that was made of aluminium.

After I build this one with a few friend of mine I decided to donate it to a friend of mine, because I already had one and I was planning to make another one so the space in my bedroom was getting smaller and smaller! Below is a picture of my “bedroom”:

I decided to build my third one because I really enjoyed to make such machines, for two reasons. The first one is easy, I really like to make mechanics and electronics. For me the second reason is that the project you make always has an end, but on this project you really make something that is just the beginning of better and nicer looking projects! Building is fun but after building comes the usage of it and that is a lot more fun in this project. Because the machines are in my bedroom I decided to make some shielding for the dust of the wood that was coming from the machine. This makes it look a bit like an actual desktop rapid prototype machine. The third machine has an accuracy of somewhere between 0.1 and 0.2 mm, this is for milling wood enough because it can stretch a bit. The third machine did cost me about 180 euro and took me 2 months of building time (spare time).

A little overview of the made costs:

-PCB with components 25 euro.
-Stepper motors (0,75 Nm) 25 euro each, so 75 euro.
-Metal tubes 10 euro.
-Multitool (kinzo) 15 euro.
-Ball bearings 8 euro.
-Bearing slides 16 euro (I got them for free from a friend).
-End switches 6 euro.
-MDF wood casing wood and acrylate glass   (scrap, I work at a hardware store so it was free).
-2 meters of screw-tread (m12×1,25) 5 euro.
-Some small things like screws and nuts.
-I also used a lot of thing I already had like a nice spindle for the z-axis.

For the red rings and shaft coupling I used an lathe to make them, I have studied fine mechanical engineering, so I used the lathe at school. I also made the PCB at school.

I made a lot of pictures of the building of the machine:

Testing the machine and make it run perpendicular.


The assambly of the z-axis.

The spindle of the z-axis.

The machine’s x-axis assembly. The linear motion of the axis is done by 4 ball-bearings which roll on a metal tube.

To make the axis run perpendicular to each other. the red ring has screw thread in it so you can positioning the tube.

The z-axis makes a linear motion because of the bearing slides which you find in a drawer.

All the components, the limit switches, stepper motors the PCB and mosfets to drive the current through the steppers.

A “IKEA” solution of making corners connect.

Here below are some of the workpieces I made with the machine’s. Some milling work and some engrave and a 3d photo.

Here’s a robot the machine milled for me, almost all the parts are made with the machine.

Milling the robot:

I made the robot to have a platform where I can experiment with sensors and to play with microcontrollers.

I hope you like it, if you have any questions, just ask.
