Excerpts from interaction session of Editorial committee with Dr U Chandrasekhar, Additional Director, GTRE Bengaluru. The interaction was based on “Research- A Career opportunity for Young Engineers”. Ed: Where can a young aspirant look to build his/her Research Career?  Dr UC: Research as the career option is available for engineers at various organizations like ISRO, DRDO, CSIR labs, BARC etc and also with many global players like GE, GM, Bosch, Daimler Chrysler etc., have setting up their R&D centers in India, the research options are on a growth path. So the numbers are continuously growing for Indian engineers. Ed: Can you list few major research projects presently being carried out in India. Dr UC: India is home for many major research works, to list I can say,

• Satellite based communication and navigation systems for rural connectivity, security needs and mobile services.

• Development of Heavy lift launcher • Reusable Launch Vehicles - Technology demonstrator missions leading to Two Stage

To Orbit (TSTO) • Human Space Flight • Chandrayaan-2 

  Ed: Large number of students community doesn’t see Research as a career. What do you like to say to them? Dr UC: Currently many engineers have started looking at R&D as a very important option. Many engineers from IITs are also joining. One example is recently department of space conducted entrance examination for their BE program (Trivandrum - IIST) and I understand lakhs of students wrote this examination. Ed: Freshers say “We don't find the growth in Research so fascinating as we get to

experience in a Private or a MNC firm" Dr UC:This thinking is no longer valid - it has changed with global careers in R&D Ed:Students in campus/ fresher feel "pace of work at Research" is a factor of concern for

them to choose this field. Dr UC: Pace of work, excitement, sense of achievement in R&D labs are also very prominent. Ed:What qualities should an engineer possess to build his/her career in the field of Research? Dr UC: Passion for research and commitment to cause. Ed: Piece of advice to students. Dr UC: If you are serious about R&D, please derive inspiration from great sons of soil like Dr. APJ Abdul Kalam, Dr, Vikram Sarabhai, Dr. Homi Bhabha, Dr. C V Raman, and you can enable world-class achievements that can impact the lives of the people from all walks of life.

NANO ROBOMEDICINE  

“A pessimist sees the difficulty in every opportunity;

An optimist sees the opportunity in every difficulty.”

Winston Churchill, (1874-1965)

Nobel physicist Richard P Feynman, in the year of 1959,  in his remarkably prescient talk, was clearly aware of the potential medical applications of the new technology and proposed employing machine tools  to make  smaller machine  tools,  these  to be used  in  turn  to make  still  smaller machine  tools, and so on all the way down to the atomic level. In connection with biological  cells, he  said  “that we can manufacture an object that maneuvers at that level”   Albert R.Hibbs, a mathematician of  Jet Propulsion Laboratory  NASA,  suggests  a  very  interesting possibility  for  relatively  small  machines.  He  said that,  although  it  is  a  very wild  idea,  it would  be interesting  in  surgery  if  you  could  swallow  the surgeon.  You  put  the mechanical  surgeon  inside the  blood  vessel  and  it  goes  into  the  heart  and looks around (of course the  information has to be fed out.). It finds out which valve is the faulty one and takes a little knife and slices it out. Other small machines might  be  permanently  incorporated  in the body  to assist  some  inadequately  functioning organ.  The  vision  behind  Feynman’s  remarks  became  a serious  area  of  inquiry  two  decades  later,  when K.Eric Drexler, while still a graduate student at the Massachusetts Institute of Technology, published a technical  paper  suggesting  that  it  might  be possible  to  construct  a  nano‐devices  from biological  parts,  that  could  inspect  the  cells  of  a living  human  being  and  carry  on  repairs  within them.  Nano‐robotics  is  the emerging  technology  field of creating  machines  or  robots  whose  components are close to the microscopic scale of a nanometer (10−9 meters). Due  to  the advances  in  the  field of nanotechnology,  nano‐device  manufacturing  has been  growing  gradually.  With  the  expected miniaturization  of  devices  provided  by  several works on nanoelectromechanical systems (NEMS), nanomanufacturing has  actually become  a  reality for  the  ongoing  developments  of molecular‐scale electronics,  sensors  and motors  are  expected  to 

enable  microscopic  robots  with  dimensions comparable to bacteria.  The  artificial  mechanical  red  blood  cell  or “respirocyte”  is  a  bloodborne  spherical  1‐micron diamondoid  1000‐atmosphere  pressure  vessel with  active  pumping  powered  by  endogenous serum glucose. It is able to deliver 236 times more oxygen to the tissues per unit volume than natural red  cells  and  to  manage  carbonic  acidity.  An artificial mechanical white cell of microscopic size, called a “microbivore,” has as  its primary function to destroy microbiological pathogens found  in the human bloodstream using  a digest  and discharge protocol. 

 Nanomedicine  is  the  process  of  diagnosing, treating, preventing disease and improving human health,  using  molecular  tools  and  molecular knowledge of the human body. Biotechnology will make possible even more remarkable advances  in molecular  medicine  and  biobotics,  including microbiological  biorobots  or  engineered organisms.  Perhaps  10–20  years  from  today,  the earliest  molecular  machine  systems  and nanorobots may join the medical armamentarium, finally  giving  physicians  the  most  potent  tools imaginable  to  conquer  human  disease,  ill‐health, and aging.  In the first half of the 21st century, nanomedicine should eliminate  virtually all  common diseases of the 20th century, and virtually all medical pain and suffering as well.  References: Current Status of Nanomedicine and Medical Nanorobotics Robert A. Freitas, Jr., Journal of Computational and Theoretical Nanoscience. Vol.2, 1–25, 2005 Institute  for  Molecular  Manufacturing,  Palo  Alto,  California, USA

GREEN ENGINE  GLOBAL ISSUES Everyday  radios,  newspapers,  televisions  and  the internet  warn  us  of  energy  exhaustion, atmospheric  pollution  and  hostile  climatic conditions.  After  few  hundred  years  of  industrial development, we are facing these global problems while  at  the  same  time  we  maintain  a  high standard of living. The most important problem we are  faced  with  is  whether  we  should  continue developing or die.  Statistics  show  that,  the  daily  consumption  of petroleum  all  over  the world  today  is  40 million barrels,  of  which  about  50  percent  is  for automobile  use.  In  accordance  with  this calculation,  daily  consumption  of  petroleum  by automobiles all over the world  is over two million tonnes. At the same time as these fuels are burnt, poisonous materials such as 500 million tonnes of carbon  monoxides  (CO),  100  million  tonnes  of hydrocarbons  (HC),  550 million  tonnes  of  carbon ©, 50 million tonnes of nitrogen oxides  (NOx) are emitted  into  the atmosphere every year, severely polluting  the  atmosphere.  Addressing  such problems  is what a Green engine does or  tries  to do. The Green engine as  it  is named  for  the  time being  is a  six phase engine, which has a very  low exhaust emission, higher efficiency,  low vibrations etc. Apart from these features, is its uniqueness to adapt to any fuel which is also well burnt. Needless to say,  if  implemented will serve the purpose to a large extent.     TECHNICAL FEATURES Compared  to  conventional  piston  engines, operated on  four phases,  the Green  engine  is  an actual  six  phase  internal  combustion  engine with much  higher  expansion  ratio.  Thus  it  has  six independent  or  separate  working  processes: intake,  compression,  mixing,  combustion,  power and exhaust,  resulting  in  the high air charge  rate. The most important characteristic is the expansion ratio  being  much  bigger  than  the  compression ratio.  Direct Air Intake Direct  air  intake means  that  there  is  no  air  inlet pipe,  throttle  and  inlet  valves  on  the  air  intake system. Air filter is directly connected to the intake port  of  the  engine,  and  together  with  the  less heating effect of air intake process, benefited from lower  temperature  of  independent  intake chamber,  a  highest  volumetric  efficiency  which 

makes engine produce a high torque of output on all speed  range  is achieved. The pump  loss which consumes the part of engine power is eliminated    Direct Fuel Injection Direct fuel injection can provide higher output and torque, while  at  the  same  time  it  also  enhances the response for acceleration.  Self‐Adapting Sealing System It can eliminate a number of seal plates or strips to achieve gapless seal and to provide most efficient and reliable sealing system with less friction.   Vibration Free As major moving parts, vanes which are counted in little  mass  and  operated  symmetrically,  the performance of the engine is very smooth. Hence, vibrations are eliminated.  CONSTRUCTION& WORKING  As  earlier  mentioned,  the  Green  engine  is  a  six phases,  internal  combustion  engine  with  much higher  expansion  ratio.  The  term  phase  is  used instead  of  stroke  because  stroke  is  actually associated  to  the  movement  of  the  piston.  The travelling of  the piston  from bottom dead  centre to  the  top dead  centre or  vice  versa  is  termed  a stroke. But,  in  this engine pistons are absent and hence, the term phase is used. The six phases are: intake,  compression,  mixing,  combustion,  power and exhaust. The  engine  comprises  a  set  of  vanes,  a  pair  of rotors  which  houses  a  number  of  small  pot‐like containers. It is here, in these small containers that compression, mixing,  combustion are  carried out. The engine also contains two air  intake ports, and a pair of fuel injectors and spark plugs.    Intake The air arrives to the engine through the direct air intake  port  in  the  absence  of  an  air  inlet  pipe, throttle and inlet valves on the air intake system. A duct is provided on the sides of the vane and rotor. The  duct  is  so  shaped  that  when  the  air moves through,  strong  swirls  generate  when  it  gets compressed  in  the  chamber.  The  air  pushes  the vane blades which  in  turn  impart a proportionate rotation  in  the  small  rotor  which  houses  the chambers.   Compression The  rushing  air  from  the  duct  is  pushed  by  the blades  into  the  small  chambers  in  the  rotor.  The 

Page 9: Yantra20 xi final

 

 

volume  of  these  chambers  is  comparatively  very small. As mentioned earlier, the compressed air  is in a swirling state, ready to be mixed with the fuel which will  be  injected  into  the  chamber when  it will  be  place  before  the  injector  by  the  already rotating rotor.  Mixing As soon as the chamber comes in front of the fuel injector,  the  injector  sprays  fuel  into  the compressed  air.  Because  of  the  shape  of  the chamber, the fuel mixes well with the compressed air. Mixing phase has enough  time  to produce an ideal  air‐fuel  mixture  as  the  spark  plug  is positioned  towards  the other end of  the  rotor or burner  Combustion A  spark  flies  from  the  plug  into  the  air‐fuel mixture.  . As soon as  the whole charge  is  ignited, the burner rotates to position itself in front of the narrow exit.  Power The  expanded  gas  rushes  out  of  the  chamber through the narrow opening, thereby pushing the name  in  the  process.  The  sudden  increase  in volume ensures that more power is released.    Exhaust As the thermal energy is fully utilized, the exhaust gases bring along comparatively  less heat energy. This mainly helps  in  the  thermal efficiency of  the engine.      ADVANTAGES  As  obvious  from  the  technical  features  which include  effective  innovations,  the  advantages  of the  Green  engine  over  the  contemporary  piston engines are many.   Small Size and Light Weight   High Efficiency Because  many  great  innovations  are  being employed  in  the engine design  such as: direct air intake,  sequential  variable  compression  ratio, super  mixing  process,  constant  volume combustion  Multi‐fuels Due  to  six  phases  of working  principle,  super  air fuel  mixing  process  and  constant  volume 

combustion  with  controllable  time,  the  Green engine becomes the only real multi‐fuel engine on our  planet;  any  liquid  or  gas  fuels  can  be  burnt well.  Ideal to Hydrogen Fuel Separation of working  chambers  from each other is an  ideal design for any fuel to prevent backfire, especially for the hydrogen fuel.   Low Cost Limited  parts,  small  in  size,  light  in  weight  and depending  upon  current  mature  materials  and manufacturing  technologies.  By  the  above contents  and  proper  explanation,  it  can  be concluded that e green engine is sure to serve the purpose of mankind to large extent.

BUGATTI VEYRON – THE ENGINEERING MASTERPIECE!!! Am sure everyone has heard of the word BUGATTI VEYRON. Yes!! It’s the fastest street legal car in the world with a top speed of over 400 km/hr!!!   The car  is  named  after  French  racing  driver  Pierre Veyron, who won the 24 hours of Le Mans in 1939 while racing for the original Bugatti Company.  The car wears  the  initials of vettori Bugatti, an  Italian who built extremely fast n powerful cars between 1909 and 1947. Bugatti came back to life when VW bought  the  rights  in 1999,  in 2001  they decide  to build  a  car  with  a  whopping  1001  BHP  which  I think  changed  the  dimensions  of  the  automobile industry. 

  The Veyron has 2 transmissions built  into one which makes  the gear  change extremely  fast and helps  it  reach 60kmph  from  standstill  in  just 2.5s!  Since  the  car  is  extremely  fast,  the  brakes have to be very powerful and are made of hi tech carbon, ceramic and titanium. This combination of materials  makes  it  work  till  1800  degree Fahrenheit. But what if the temp exceeds 1800 f?? bugatti’s engineers had a solution to this problem . They  designed  a  retractable  rear  spoiler  which comes  up  automatically while  braking  and while cruising at  very high  speeds  in order  to  keep  the 

Page 10: Yantra20 xi final

 

vehicle  firmly on  the ground. The  sensors  for  the spoilers  come  from  a  company  which manufactures sensors for aircrafts. 

Driving a Veyron would be  like driving an aircraft  on  road  because  most  of  the  parts  are manufactured by the companies who manufacture parts  for  aircrafts.  The  Veyron  has  custom made Michelin tyres which can take it safely to the car’s top  speed  of  407kmph.  The  company  says  those tyres can withstand torture till 447Kmph!! 

The bugatti’s factory which is in France has just 17 workers!! U may be surprised to know that this car doesn’t  have  a  chassis  at  all.  It’s made  up  of  3 different  sections which are  later  joined  together using bolts and nuts!! The car was tested  in VW’s secret test track which has a 9km straight stretch. Interestingly,  u  cant’t  see  the  other  end  of  the track as its following the curvature of the earth!

THE T-800 

Robot  researchers  led by Markus Grebenstein  in Germany have taken a step towards making the T‐800 a reality this week by creating a super strong robot hand.  It even  looks  a  little  a  lot  like  the T‐800: 

 

 

As  the  picture  above  shows,  this  hand  is  very strong  and  one  of  the  fingers  can  be  hit with  a hammer at speed and not get damaged.  It has 38 tendons with a motor attached to each finger and is  of  similar  size  to  a  human  hand.  Dexterity  is built‐in  and  the hand has 19 degrees of  freedom (one  less  than  us)  and  a  force  of  30  N  can  be applied at the fingertips. 

The  hand  was  developed  at  the  Institute  of Robotics  and  Mechatronics  at  the  German Aerospace  Centre.  The  secret  to  its  strength  is  a combination  of  a  synthetic  fiber  called  Dyneema and a spring attached to each tendon. That allows each  finger  to  take a hard blow, but at  the  same time  move  to  reduce  the  force  while  easily springing back to its original position. 

The end result is a very strong hand with almost as much  freedom  of movement  as  a  human  hand. Movement  speed  at  the  joints  can  reach  2,000 

 

Page 11: Yantra20 xi final

 

degrees per second allowing  the hand  to snap  its fingers. 

Not only is it strong, but the use of springs on the joints  allows  the hand  to monitor  and  adjust  the force of  its grasp based on  the object being help. The  lower the tension on the  joints the softer the object must be and can therefore be grasped more lightly. 

   Employees are one of the most expensive and yet the  greatest  asset  to  any  organization.  They develop a  set of  skills  that  is acquired on  the  job through  training  and  experience,  and  which increase that employee's value in the marketplace. In a successful ergonomics process, the employees are not "blamed" for injuries and/or waste, but the jobs  themselves  are  assessed  and  changed when needed. 

The main reason for the development of the hand was to improve the robustness of robotic hands in general.  Grebenstein  points  out  that  even  the most  agile  of  robot  hands  can  easily  break with small  amounts  of  pressure  on  them.  This  new design  solves  that  problem  without  inhibiting movement or speed. 

As for how much this hand cost to develop: it’s less than $135,000. Now  the  research  team  is  turning its  efforts  to  a  two‐armed  torso.  Thankfully,  no one yet seems to be working on  legs so this thing could  only  escape  by  dragging  itself  across  the floor.

ERGONOMICS:

A Management Asset and Manufacturing Excellence

Ergonomics  is a study of the relationship between people and their working environment as a means to  improve efficiency. A workplace whether  it  is a factory  or  an  office,  needs  to  be  planned  and systematically  designed  to  provide  the  best possible support for quality work.  

 A new  study  shows  that  one‐third  of workers  in the western countries are chronically overworked and  even  more  feel  over  overwhelmed  and stressed  by  their  jobs.  The  figures  in  Indian industries are not exactly known. We know  in the short  run  that  if employees are overworked,  they are more  resentful  and  angry  and  commit more mistakes. In the long run, we are talking about the effects of stress and work conditions on health.  

Ergonomics: A Management Asset  

Ergonomics  deals  with  risk‐return  trade‐offs. Ergonomics  engineering  mitigate  risk  by engineering out a problem. By  removing  the  risk, potential for additional costs and labour problems can  be  ended  and  can  manage  and  control  the expenditure  for  the  solution.  Risk  can  be transferred  through  means  such  as  insurance coverage. With  this method,  you  are  paying  the insurance company to assume the risk but you still pay.  

The  ergonomics  engineering  can  provide  the roadmap  to  cost  reduction  by  imparting  the knowledge  and  increasing  the  intellectual  capital for  all  employees.  By  using  intellectual  capital  to reduce  costs,  it  can  maintain  experienced employees  rather  than  the  "revolving  door" syndrome,  create  solutions  to  jobs  that  produce risk  factors  to  the  human  body,  understand "upstream" design prior to cutting a piece of steel in  the plant,  train office employees  in  the proper

adjustability  of  their  equipment,  educate healthcare  workers  in  proper  lifting  techniques, take warehousing and supply chains and design  in solutions while designing out problems.  

Ergonomics : A Manufacturing Excellence  Companies  need  to  meet  the  expectations  of "doing  more  with  less".  To  achieve  this  one approach  that  has  proven  effective  in  scores  of manufacturing companies is to leverage the efforts of  ongoing  improvement  initiatives  to  accelerate ergonomics improvements. Generically referred to as  "manufacturing  excellence",  these  initiatives range  from  Lean Manufacturing  to  Six  Sigma  to Demand  Flow  Technology.    The  techniques may differ,  but  they  all  have  a  common  goal:  drive bottom‐line  improvements  by  working  smarter. Manufacturing  excellence  initiatives  are  how things  get  done  in  manufacturing  today.  If  you want to modify a manufacturing process to reduce ergonomic  risks,  the simplest approach  is  to align with  the  Kaizen  improvement  team  activities. Integrating  your  ergonomics  efforts  with  these initiatives,  however,  means  one  have  to  ensure that  ergonomics  process  is  systematic  and  data‐driven. 

The  ability  to  manage  ergonomics  knowledge represents  one  of  the  primary  opportunities  for achieving  substantial  savings,  significant improvements  in  human  performance,  and competitive  advantage.Manufacturing  excellence initiatives  do  not  tolerate  opinion  and  intuition, decisions  are  formalized  and  projects  are  funded based on data analysis 

Engineering  ergonomics  can  foster  continuous improvement  in  any  organization  by  using  the science  for  changing  a  corporate  culture  through the education and  transfer of knowledge. Training an  organization's  engineering  staff  in  applied ergonomics  for  processes,  product  design,  design for manufacturing and assembly, equipment design and  selection,  supply  chain  management,  facility environments  and  maintenance  can  produce  a variety of benefits. Other personnel such as health, safety,  maintenance,  purchasing  and  production employees need  to be  trained after  the engineers. This  allows  a  natural,  logical  chain  of  events whereby an employee  identifies an ergonomic  risk factor  and  the  engineer  has  the  knowledge  to understand and develop  the  solution  to  reduce or eliminate  the  hazard.  Otherwise,  labor  and management may have a real schism when a risk is found and no one can change it.  

- Ergonomics  can  impact  work  organization  by adding  to  efficiency  and  reducing  errors  and waste.  Ergonomics  can  identify  risk  factors  to reduce workers’ compensation, disability costs and  lost work  time costs. Ergonomics  leads  to the design of workstations and accessories that are comfortable, and helps create new designs for  products,  equipment  and  tools  that enhance productivity. 

 - The  quantity  and  quality  of  work  can  be 

improved  by  using  the  correct  layout  plan, storage, furniture, colour scheme, and lighting. Office  interiors  have  been  proved  through research  to  influence  the  behaviour  of employees. Appropriate colour schemes, which are  preferably  pastel  or  bluish,  have  been proved  to  help  in  concentration  and  work productivity.  Excessively  bright  or dull  colours should  be  avoided.  Health  of  employees depends  to  a  certain  extent  on  the  interior design.  Dull  stodgy  colours,  scattered  storage spaces and uncomfortable work areas can slow down work productivity and cause illnesses and absence  from work.  The  opposite  happens  to be true. If the design can incorporate pleasant, motivating  interiors  with  comfortable  chairs and  desks  with  proper  storage  and  a  layout plan, the possibilities of better work progress is likely.  

In  the  present  scenario  ergonomics  engineering present many avenues for students and engineers from  all  streams  to  specialize  in  this  flourishing field.  Organizations  and  universities  has  realized the worth of this specialized science of ergonomic engineering  and  many  courses  and  training programs  are  been  conducted.  Ergonomics engineering  is  not  only  an  asset  to  the management, it also a manufacturing excellence.

INDIAN DEFENSE FLYING WITH OWN WINGS

Indian defense is proud about the recent developments  in  its R&D Division which came out with Light Combat Aircraft‐ TEJAS. 

Tejas, the Indian Light Combat Aircraft, re‐scripted the history of Indian Aeronautics in Golden letters. Success  story of Tejas  is an epitome of corporate collaboration  involving R&D  laboratories of DRDO, CSIR,  CEMILAC,  DGAQA,  and  Defence  PSUs  like HAL,  BEL  and  many  more.  Private  sector participants  and  prominent  Educational Institutions, all coordinated by nodal organization Aeronautical  Development  Agency  (ADA)  was established  with  the  sole  purpose  of  developing Tejas, delta‐winged machine. 

The  Tejas,  or  ‘radiance’,  is  an  indigenous  fighter aircraft  jointly  developed  by  Aeronautical Development  Agency  and  Hindustan  Aeronautics limited.  It  is  the  smallest  light weight, multi‐role, single‐engine  tactical  fighter  aircraft  in  the world and  is  being  developed  in  single‐seat  fighter  and twin  seat  trainer variants  for  the  Indian Air Force and  Indian Navy. The aircraft will enter service  to replace  the  erstwhile  warhorse  of  the  IAF,  the MiG21 (Mikoyan‐ Gurevich MiG‐21). For the Navy, the  Tejas  will  replace  the  Sea  Harrier  and complement  the  MiG  29K.  The  Tejas  has  been conceptualized and designed by India, and its open architecture  design  will  allow  the  designers  to continuously  adapt  and  upgrade  it  to  meet  the challenges  of modern warfare.  Its  small  size  and footprint will enable  frontline units to quickly and effectively  deploy  it  for  combat  operations.  The sheer  flexi  that  Indian  Design  and  development brings  to  the Tejas weapon  system means  that  it will be a simple matter to modify and upgrade the Tejas at any stage of its service life, thus making it the most cost effective fighter platform for the IAF in the decades to come. 

Tejas‐LCA  is  ready  for  the  Initial  Operational clearance  (IOC).  After  the  certifications  namma Bengaluru  based  state  owned  aircraft  maker‐ Hindustan  Aeronautics  Limited  (HAL)  will  start rolling out Tejas in the next few months.

ONVECWITH GD&T   

In  the  days  before  globalization  of manufactu

d  in the same  facility. Any disputes abouttation  of  design  intent  during  inspectioasily  resolved  by  face‐to‐face  discussio designer. 

Today,  with  products  being  designed  in  one country  and  manufactured  in  others,  such cplace.tifathimplications with good parts being rejected or badparts being accepted.  It helps  if  the  inspector hasan understanding of  theto  function.  A  good  drainTto y design intent so inspectors know how to do their measurements.  

What is GD&T?  D&T  is  a  communiG

particularly  helpful  in  a  global  economy  where parts may be made  in one par  of  the world and used  in  another.  GD&T  is  increasingly  being accepted as the best way of specifying 3‐D design dimensions  and  tolerances on engineering design drawings. The currently recognized GD&T standard in the United States  is ASME Y 14.5M  (1994). The ISO parallel of ASME Y14.5  is  ISO 1101. Although both  standards have  the  same goal,  they are not exactly equivalent, and  it  is  important to know  to which  standard  the  drawing  complies  when measuring a part.  As  design  software  and  machine  tools  have 

become more capable,  ina

dimensions  thain 

An example of a part with critical dimensions and tolerances  is  a  plastic  part  designed  to  eliminate fasteners.    By  making  a  part  with  features  that mate  to another part, assembling  those parts can eliminate  the need  for  screws,    reducing  costs  in 

parts and  in assembly operations. However,  sizes and positions of those mating features can be criti‐ cal, with extremely  tight  tolerances. An  inspector measuring  those  features,  but  referencing dimensions from the wrong positions may make  the wrong decision. Properly specifying  and  using  datums    in  GD&T  can  help avoid such errors.  

 Inspection  equipment  measures  parts  for  two main  reasons—production  acceptance,  which  is compliance  to  specified  tolerances,  and troubleshooting  or  problem  solving  of  the manufacturing process.  

GD&T  drawings  typically  reflect  the  first  reason: they  specify  conditions,  or  tolerances,  for  part acceptance  from  a  functional  point  of  view.  A drawing will  have  one  or more  datum  reference frames (DRF) with tolerances located and oriented relative  to  each  DRF.  The  ability  to  properly construct  a  DRF  during  the  inspection  process  is crucial to the succes  of the evaluation.  To  properly  construct  a  DRF,  it  is  important  to strictly  follow  the  rules  as  specified  by  the standards  ASME  Y14.5  and  ASME  Y14.5.1.  These ules determine  thrdegrees  of  freedom  that  are  eonstraints  the  primary  datum csecondary  and  tertiary  datums,  and  the mathematical  fitting  technique  used  to  construct the  individual datum simulators.   A  typical  old‐fashioned  mea uremen   would simply  execute  a measuand  print  the  results.  While  this  approach  is acceptable for certain cases such as verifying sizes of features, it is not acceptable in all cases and will lead  to  incorrect  results  when  the  drawing contains  DRFs  that  do  not  fully  constrain  all  the degrees  of  freedom  or  have  maximum  material condition (MMC) or least material condition (LMC) modifiers attached to a datum reference. 

 In  these  cases  the  DRF  can  only  be  correctly determined after all of the measured points in that DRF are collected.   This means that before starting the  evaluation  process,  the  nominal  data  (CAD) tolerancing  information—datums,  toler  ance callouts and the measured  ata must be available.  This is calle  a GD&T Evaluation Environment.  

W rking in  GD&T envir nt  The first step to working  in this environment  is to import the nominal data of the geometry typically available  as  a  CAD  model.  It  is  important  to understand  that  CAD  design  software  and

CAD  software may  introduce  uncer‐  tainties  into the inspection process. One example is rounding of dimensions. If features used as datums hav

cIGES, VDA,  STEP or other  formats may modify or lose some geometrical data. It  is  important  to  understand  that  even  if  the metrology  software  claims      that  it  is able  to use native  CAD  ormats,  the  interpretation  of  these formats  is  left to the measuring software and can become  a  source  of  discrepancies  duein

Typical problems encountered duriageometry or the incorrect location of the imported features.CAD software uses NURBS (B‐splines) as a generic way of describing any geometrical surface and does no  contain information   the shap  is a cylinder, plane or a circle. That  forces  the  ta

software. During this process good GD&T software would  have  some  tools  available  to  expose  any CAD import issues.  The  next  step  is  to  import  the measured data.  If the  data  is  collected  by  a  CMM‐like  device,  it  is imported  directly,  but  if  thenoncontact  technology  such  as  a  laser  scanner, there may be a need  for  intelligent data  filtering. Intelligent data  filtering means that the measured data  is  evaluated  and,  if  needed,  measurement noise  is  emoved  and  the  number  of  points  is reduced.    This  p

 Is least squares enough?  Best‐fitting is fundamental to the GD&T evaluation process. Best‐fitting  is used  to correctly construct the  DRF  and  then  to  optimize  all  the measured deviations. The difference between good and bad evaluation  software  is  its  ability  to  use  the appropriate  not  the  most  convenient  fitting technique.  There  are  a  number  of  fitting echniques availablet ‐max,  tolerance  envelope,  fitting with  constraints, weighted best‐fitting, maximum  inscribed cylinder (circle),  minimum  circumscribed  cylinder  (circle), and tangent  line or plane.   These techniques exist for a  reason and address  specific goals. They  can be applied to geometric element fitting or to point clouds to surfaces best fitting.  

Consider DRF  creation. Assume  evaluating  a  part with  a  plane  for    primary datu   ‘A’  and  a perpendicular  inside cylinder deriving a secondad

teaverage  plane  instead  of  the  necessary  tangent plane. A tangent plane properly simulates the way the  part will work.  At  the  same  time,  free  least squares  inside  cylinder  instead  of  a  maximum inscribed cylinder calculated constrained to datum A, will  lead  to  creation  of  a DRF which  does  not represent how the part functions. As a result there will  be  a  systematic  error  for  all  of  the  results evaluated in that DRF and certainly a probability of bad parts being accepted and good being rejected.    Tech Tips 

• GD&T makes it easier for designers to convey design  intent  so  inspectors know how  to do their measurements. 

• GD&T  drawings  typically  specify  conditions, or  tolerances,  for  part  acceptance  from  a functional point of view. 

• Best  fitting  is used to correctly construct the DRF  and  then  to  optimize  all  the measured deviations. 

• Using  ASME  Y14.5  and  ASME  Y14.5.1  is  the right  way  to  go  when  specifying  drawing requirements  and  evaluating  parts  for acceptance.

Let’s know NPTEL better!!

19 

The  National  Programme  on  Technology Enhanced  Learning  (NPTEL)  is  a  Government  of India  sponsored  collaborative  educational programme. By developing curriculum‐based video and web courses, the programme aims to enhance the quality of engineering education  in  India.  It  is being  jointly  carried  out  by  7 

 

Gone are  the days when we had  to slog 

in  classrooms  and  follow  the  lectures  accurately, scribble down notes knowing well that even  if we intended to miss a single class for a reason, indeed we  would  be  in  two  minds  as  there  was  a  fair chance of  losing a good amount of that  important lecture for a subject which was considered a mass backlog paper and even  if we managed to get the notes  later from our friends,  it was a real struggle to understand it. 

Cut to the present day. It is now possible to obtain a  degree  from  Harvard  University  while  you  are relaxing in your living room. It is possible to access MIT  courses on  your personal  laptop  and even  if you are not a student at Stanford University, you can still catch most of the lectures on Youtube. 

Wait  I know what you guys are probably thinking. Where do our  country  India  stand  in  this  race of imparting  free  technical  knowledge  in  the  global stage. Well I have an answer. 

It is called NPTEL. Here’s all that you need to know about it and hence broaden your horizons. 

  

 NPTEL

IITs  and  IISc 

Bangalore, and is funded by the Ministry of Human Resources  Development  of  the  Government  of India.  

As  of  December  2009,  over  250  courses  were available online. The course videos are available in streaming mode, and may also be downloaded for viewing  offline.  The  video  files  are  also  viewable via the IIT Channel in Youtube. 

Seven IITs and the Indian Institute of Science (IISc) have worked together to develop web and video based material for basic undergraduate science and engineering courses in order to enhance the reach and quality of technical education in India.

The NPTEL Program 

Participating Institutions 

• Indian Institute of Science, Bangalore • Indian Institute of Technology, Delhi • Indian Institute of Technology, Guwahati • Indian Institute of Technology, Kanpur • Indian Institute of Technology, Madras 

(coordinating Institute) • Indian Institute of Technology, Mumbai • Indian Institute of Technology, Roorkee • Indian Institute of Technology, Kharagpur 

History of the Programme 

The idea of having a Technology enhanced learning initiative  involving  IITs  and  Indian  Institutes  of Management  (IIMs)  was  first  proposed  by  IIT Madras  in  the year 1999  immediately  following a Workshop  on  Technology  Enhanced  Learning (WoTEL)  conducted  in  Chennai  in  collaboration with  Carnegie  Mellon  University  (CMU), Pittsburgh, USA. 

Cost  of  the  initiative:  The  Ministry  of  Human Resource  Development,  Government  of  India approved funding of 20.47 crores (204.7 million) of Indian  Rupees  for  Phase  I  for  three  years  from June  2003  till  June  2006,  which  was  eventually extended till June 30, 2007. 

Following  that,  significant  infrastructure  for  the production  of  video‐based  teaching  material  by the  institutes was set up.  In the  first phase of the NPTEL  project  (June  2003‐June  2007),  110  video courses  and  129  web‐based  courses  were

developed  by  the  faculty  members  of  these institutions. 

Future Plans of the Project: 

Phase II: The next phase of the programme is now ongoing. Over 1000 web and video courses will be created. 

There  are  several  enhancements  being  included for Phase II 

• All  IITs  and  IISc  will  participate  as partners.  In  addition  NIT  and  other premier  University  faculty  will  have  the opportunity  to  join  for  open  content creation as associates. 

• Private  industries  will  be  called  on  to provide  value‐added  case  studies  and experiential learning. 

• There  is  increased emphasis on having  a modular structure for the courses 

• Question  banks  and  case  studies will  be included  as  part  of  the  courses  where applicable 

• The course materials will be developed to contain greater  relevance  to professional examination and industrial practices 

• Course specific NPTEL wiki's for increased interaction and user‐content generation 

Engineering Disciplines for NPTEL Courses 

In  Phase  I,  five  branches  of  engineering  (Civil, Electrical,  Electronics  and  Communication, Computer  Science  and  Engineering,  and Mechanical)  were  addressed  in  the  first  phase. Each  Institute  identified  the  courses  in  which  it would  like  to participate as video  (V) or Web  (W) based  content  contributor.  The  core  courses common  to  all  these  disciplines  including  basic science and engineering were addressed by a core courses group. 

 

 

 

 

 

As of December  2009, web  and  video  courses  in the following disciplines are available.

CAREER OPPORTUNITIES IN ROBOTICS  

In  the  last  few  decades  technology  has been  the  major  force  driving  industry  forward. Automation  has  been  the  most  important component  to  instill  efficiency  into  industrial processes. On the other hand, human resources to achieve  automation  have  also  been  required  in great  numbers.    Robotics  has  been  at  the  forefront  of technological  innovation  into  more  and  more automation.  It  is  the  science and  technology  that drives robots to do all sorts of process related jobs more efficiently than humans can ever do without getting  tired. Robots  are mechanical devices  that are  computer  controlled.  The development of robotics and robots obviously requires human resource, expert  in diverse areas. Requirement  list  begins  with  mechanical engineers,  computer  scientists,  process technologists,  experts  in  material  sciences,  and system  integrators.  Further  field  needs  quality control engineers,  instrumentation engineers, and control  system  engineers.  The  mechanical  engineers,  control  system designers, and information technology experts are the most prominent personnel  required  for  robot design,  construction,  and  actual  operation  of robots  for  specific  industrial  processes.  The  automobile  industries  across  the  globe  are extensively  using  robots  in  assembly  lines.  Their development  requires  knowledge  about automobile  assembly  processes  and  mechanical engineering.  Control  system  engineers,  software developers,  instrumentation  engineers,  and electronics  engineers  are  also  required  for developing  and  improving  them.  Information  technology  (IT)  is also an area where robots  are  used.  Intel  and  AMD  use  robots  in developing  the  latest microchips. Nanotechnology is  a  recent  domain  wherein  robots  are  seen  as requirement. Besides industry, robots are 

 being used more and more for personal use as toys or as security guards. Robots are also used in 

cleaning nuclear active rooms/areas. Recent developments and researches have opened up the window of medical sciences wherein robots are used to assist surgeries and in few applications used to assist the support staff in hospitals in better caring of patients. Opportunities to kick start a career are plenty and readily available in robotics in these budding fields.  Besides all these fields, you can also find an opening in off the focus areas such as‐ deep sea ocean exploration, the study of volcanoes, the Antarctic, and in archaeology. For quote ‘A hitherto unknown tunnel was found in the main pyramid at Giza in Egypt through use of a miniature robot’. Astronomy is the field wherein robots play an important role in many of the celestial expeditions. We can all remember the Pathfinder robotic vehicle still working on Mars.  It  is  important  to  see  that  robots  are  used exclusively  in  certain  areas  and  conditions.  They are specifically used where the reach of humans is highly  impossible,  such  as  hostile  environments‐ dusty,  chemically  active,  high  temperature applications  and  many  such  areas  where  the involvement  of  humans  may  be  hazardous  to health.       It is therefore not very difficult to forecast that, in  the  coming  years  more  and  more  career opportunities will  be  forthcoming  in  the  field  of robotics  for  young  engineers‐  brain  filled  with innovative  ideas  and  knowledge.  An  interest  in robotics and systems development is an important pre‐requisite to pursue a career. A basic degree in a  compatible  engineering,  science,  or  technology discipline  is what  is  essentially  required.  You will have  better  growth  in  robotics  if  you  gain worthwhile  experience  in  the  initial  two  years  of your career.

Motivational Story

Boy was born to a couple after eleven years of marriage. They were a Loving couple and the boy was the gem of their eyes. When the boy was around two years old, one morning the husband saw a medicine bottle Open. He was late for office so he asked his wife to cap the bottle and keep it in the cupboard. His wife, preoccupied in the kitchen totally forgot the matter. The boy saw the bottle and playfully went to the bottle fascinated by its colour and drank it all. It happened to be a poisonous medicine Meant for adults in small dosages. When the child collapsed the mother hurried him to the hospital, where he died. The mother was stunned. She was terrified how to face her husband. When the distraught father came to the hospital and saw the dead child, He looked at his wife and uttered “I am with you" The husband's totally unexpected reaction is a proactive behavior. The Child is dead. He can never be brought back to life. There is no point in finding fault with the mother. Besides, if only he had taken time to keep the bottle away, this would not have happened. No one is to be blamed. She had also lost her only child. What she needed at that moment was consolation and sympathy from the husband. That is what he gave her. If everyone can look at life with this kind of perspective, there would be much fewer problems in the world. "A journey of a thousand miles Begins with a single step." Take off all your envies, jealousies, Unforgiveness, selfishness, and fears. And you will find things are actually not as difficult as you think. MORAL OF THE STORY Sometimes we spend time in asking who is responsible or whom to blame, Whether in a relationship, in a job or with the people we know. By this Way we miss out some warmth in human relationship.

About a week later St. Peter Saw him being whipped by the demons And then he asked St. Peter ‘ What happened to all the beautiful women and the Beaches…. St. Peter replied, “That was just the screen saver”

 

Make a Difference: I awoke early, as I often did, just before sunrise to walk by the ocean's edge and greet the new day. As I moved through the misty dawn, I focused on a faint, far away motion. I saw a youth, bending and reaching and flailing arms, dancing on the beach, no doubt in celebration of the perfect day soon to begin. As I approached, I sadly realized that the youth was not dancing to the bay, but rather bending to sift through the debris left by the night's tide, stopping now and then to pick up a starfish and then standing, to heave it back into the sea. I asked the youth the purpose of the effort. "The tide has washed the starfish onto the beach and they cannot return to the sea by themselves," the youth replied. "When the sun rises, they will die, unless I throw them back to the sea." As the youth explained, I surveyed the vast expanse of beach, stretching in both directions beyond my sight. Starfish littered the shore in numbers beyond calculation. The hopelessness of the youth's plan became clear to me and I countered, "But there are more starfish on this beach than you can ever save before the sun is up. Surely you cannot expect to make a difference." The youth paused briefly to consider my words, bent to pick up a starfish and threw it as far as possible. Turning to me he simply said, "It made a difference to that one." I left the boy and went home, deep in thought of what the boy had said. I returned to the beach and spent the rest of the day helping the boy throw starfish in to the sea. Based on the story by Loren Eisley

Musings of a Confused Engineering Mind

“Should I wear this red tie or should I pick up the maroon one instead for today’s meeting with my client?”...”Should I laze around in the house for the weekend or just chill out with my friends

at the discotheque?” I believe each one of us at some point of the day go through a similar phase of indecisiveness.

Any guesses? The word is “Confusion”. Yes, it is this confusion that rules the world and beyond. Till date even the top notch scientists are speculative over the origin of the universe and space-time and hence they had to seek refuge into a number of theories such as the Big-Bang Theory, the String-Theory among others. But this doesn’t end confusion from their minds for they are

constantly at work to find a full-proof theory that would describe every property and characteristics of the universe and answer the myriad questions hurled by the critics out there.

Now that was about the scientific world where confusion reigns supreme. Now coming to our practical world, confusion plays no lesser part in almost every aspect of our lives. Very few

smart and able men can keep confusion at bay. The remaining are confused right from dawn to dusk. I belong to the latter category.

About me, I was as much confused in childhood as I am now. Confusion seems to be synonymous with my name. Confused? Let me clarify. My name is an amalgamation of a complex set of

unpronounceable syllables as a result of which often people find it difficult to pronounce my name and as a result end up spelling it wrongly. No doubt most of my marks card bare the same

name but with different spellings. My fate! Another trait of my eternal confusion is that it was only when I was in the seventh grade that I came to distinguish between the left and right sides over which I get confused sometimes even

now. Moreover, after being confused for all these years I can say that I’ve attained some sort of

mastery over this special trait possessed by me. My confused state of mind can be divided into three categories.

The first one is that I am a person who is scientifically confused. No doubt I nursed a personal grudge against Newton when I was in school. As a result I ended up messing my grades quite

often in school which was followed by a letter to my parents from the principal. But interestingly or rather confusingly the letter never found its way to my home.

However, I am proud to belong to this class of scientifically confused people because I personally believe that all great scientists were a confused lot and in the process of removing their confusion they ended up discovering or inventing something extraordinarily great. Now I

am not saying that I am great for I have my confusions over that as well! Secondly, I’m a person who is spiritually confused. I am confused for that matter because if

God is one and all religions preach the same tenets of finding God, then how come so much hatred and sin in the name of religion all over the world. All these make me all the more

confused. Lastly, I am a person who is simply confused. I sometimes wonder had there been some sort of

Confusion Quotient (CQ) to measure the degree of confusion of the mind, I am sure I would have had a high CQ level.

None of my tasks are completed without the timely intervention of confusion. But I must say that I am proud to possess such a powerful quality for with the help of this special trait many

minds have produced many things unheard of before. So why can’t I? With this bit of solace I continue my journey hand in hand with this faithful companion for many

more confusing days to come in future...
