Gyroscopic effect on airplane:



Gyroroscope effect will usefull in determining the direction in wich the aeroplane nose and tale will move while taking a turn in either direction like left or right ...it have several conditions...like if we are noticing from the rare side(back side) whn the plan take a left cut ..and the rotter of the plan is moving in the clockwise direction..then the nose get up and the tail goes down...because of the active and reavtive gyroscopic couple fore which are acting in opposite direction and equal in magnitude...
(2)-if plan takes a right turn in the same conditions the action of the tail and nose will be the vice versa of the 1st result...
if rotter in moving in anticlock wise direction...then the result 1st and 2nd will be the vice versa ...
(3)-condition 2nd...if we notice it from the front the all results are oppsite...for e.g if plane turns left then the nose get down and tail gets down in direction ......so nw u can get all result by transforming them into the jst opposite to the results of the condition 1st...results

Significance of governor in automobiles:



Governor is an important component of automobile engine. It is used to regulate the main speed of engine during the variations in loads. With the variations in the load, fuel supply has to be maintained. This task is performed by the governor. In the case of high load on the engine, speed decreases, hence fuel supply has to be increased and similarly when load decreases then the fuel supply has to be decreased.

Electrochemical machining (ECM)



It is a method of removing metal by an electrochemical process. It is normally used for mass production and is used for working extremely hard materials or materials that are difficult to machine using conventional methods. Its use is limited to electrically conductive materials. ECM can cut small or odd-shaped angles, intricate contours or cavities in hard and exotic metals, such as titanium aluminides, Inconel, Waspaloy, and high nickel, cobalt, and rhenium alloys. Both external and internal geometries can be machined.

ECM is often characterized as "reverse electroplating," in that it removes material instead of adding it.

Working of air conditioners in cars:




Air conditioners are based on the principles of evaporation and condensation and then compression and expansion. The hot air of the car is removed by the process of evaporation and then the condensation of the evaporated air takes places which is then further compressed by the compressor and then finally expanded to us in the form of cold breeze. Somehow, Air conditioning reduces the average of the car, as the energy is required to remove the hot air and then compression and expansion.

Universal joint

Universal joints are used for connecting two shafts inclined at angles to one another. For transmitting the rotary motion from the engine to the road wheels throughout the variations in position of the rear axle with respect to the gear box and chassis, universal joints are most suitable. It shows the principle of universal joint.

Detonation

It is caused by the fuel with a low octane rating and is the tendency for the fuel to autoignite in an engine combustion chamber.
The resulting knock or ping is the sound of the pistons slamming against the cylinder walls. Severe detonation can break pistons and destroy engines.
This early ignition of fuel creates a shock wave throughout the cylinder as the burning and expanding fuel air mixture collides with the piston that is still traveling towards T.D.C. (top dead center) .

Hydraulic lifting (valve)

All the engines have hydraulic valve lifters in one form or another. The most common types of engine that has them is your vehicle engine. They created to get rid of the need for combustion engines to have mechanical clearance in the engine valve train.
The reason that clearance is required is to keep the valve from being held open and destroyed as the valve train goes through its process of thermal expansion. In in effect, hydraulic valve lifters keep the valve healthy and protected from an engine normal thermal expansion process.

Differential


Differential  : When the vehicle travels around a corner, the distance traveled by the outer wheel is greater than that traveled by the inner wheel. If the wheels are mounted on dead axles so that they turn independently of each other, (the front wheels of the vehicle an ordinary vehicle) they turn at different speeds to compensate for the difference in travel. But the the wheels are positively driven by the engine to device is necessary to permit them to revolve at different speeds without interfering with the propulsion of the vehicle. To accomplish this purpose, a system of the differential gears is provided to allow the outer wheel to revolve at a higher speed than the inner wheel while turning corner. In this way, the inner wheel skidding of the which involves the sliding friction. being harmful for the life of the tyres is overcome


Construction and working :
Figure shows the construction and working of the differential mechanism.
It Consists of The Following components:
(i) Crown wheel or ring gear
(ii) Drive pinion or crown pinion.
(iii) Cage
(iv) Sun gears
(v) Planet or star pinions.
The drive pinion meshes with the crown wheel. The crown wheel is free to rotate on the rear axle half shafts whereas the sun gears are splined on the ends of each half shaft. The cage is rigidly attached to the crown wheel. The cage consists of the pin on which two planet pinions are mounted. The planet pinions are free to rotate on the pin but are meshed with the sun gears.


When the vehicle is traveling straight in the head position, the power flow from the drive pinion is shown in the Figure a. The drive pinion gives the power to the crown wheel whereas the crown wheel, cage, the pin and the planet pinions rotate the one unit. The planet pinions revolves on the pin but the axes their transmit the power to the sun gears. The sun gears and the half shafts are splined together and revolve due to the rotary motion of the planet gears to the whole .

Cone clutch


It shows the cone clutch. It consists of two cones, internal and external cone. Friction material of a wire and asbestos are used for fitting on internal cone. The cones are held together in position by a large and strong coil spring. The torque is transmitted from the engine to the flywheel and internal cone to the splined shaft when the clutch is engaged. The foot operated clutch pedal is employed to pull out the internal cone and overcome the spring pressure during disengagement of the drive. Cone clutch was used for larger and earlier type vehicles but now it has become obsolete due to certain disadvantages.

Press and Weld Operations for Front Fender (Scooter)


  
The Honda Two Wheeler press shop consists of 4 Hydraulic Presses capable of producing 350 Ton force each. A bank is fed into the first press which is draws it into the form. The next press is fitted with a shearing die which cuts the excess parts (flashes) and pressed part is finished. 



The finished part is visually inspected and buffing is done to ensure that no defect/dent reaches the weld area. The presses work in pair of two. One for drawing and second for shearing.
Then these parts are sent to the weld section where they are clamped in a jigand a robotic arm welds the two parts together. An operator then checks the weld done by the robot in order to ensure that there is no welding miss or spatter. These defects are rectified by manual welding or by buffing. The second part of the fender is welded using spot welding. The weld is then inspected again. Finally the brake wire harness is welded. Also the L stay and R stay are welded (Stay are the clips) which are used to hold the fender along with the fork assembly. A fiber tool is used to remove any seam from the external surface.The welded part is then sent for paint. Where it is painted and sent for Fork Assembly in AF-1

FRAME ASSEMBLY PROBLEMS:


  1. Swing arm pressing.
  2. Handle switch fitment.
  3. Reducing line stoppage.
  4. Race cone pressing.

KAIZEN Philosophy: -


 KAIstands for “change” and ZEN stands for “improvement”.
So KAIZEN means, “Continual change for improvement”. This is the activity, which is open for all the employees, and all the employees take keen interest in this activity. “The more the number of Kaizens in a department, the more is the honor for the same” makes this event very much interesting.

Why to choose the PDCA Approach…….?


1.   Being a closed loop, it helps in better control of the various steps.
2.   Like a closed loop system it gives feed back and thus better control of the   
   various activities.
3.   It helps in continual improvement of the methods.
4.   It helps in pin-pointing the problem.
5.   Better comparison between Planned and Actual Achievements and time.
6.   Makes the things simpler and easier to understand as each step is self-explanatory.
7.   Better understanding of the basic procedure being followed.
8.   Helps in better and positive thinking.
9.   Helps in achieving the results in a more systematic manner.
10. Helps in finding the root cause of the problem.
11.Continuous monitoring approach resulting in better achievements.
12.Development of new ideas.
13.Better and safe approach towards the problem.
14.Examination of the problems and their countermeasures is more systematic.
15.It is a systematic approach towards the problem.

RESEARCH METHODOLOGY


This methodology will explain how I went about doing my project. It is divided into two sections Sampling details & Data collection + analysis. In this there will be explanation of what kind of sample data I have taken for my project and the collection of that data.

 

SAMPLING AND DATA COLLECTION:

For the completion of my project I went through the random sampling of data. In which I have picked up some components randomly for the observation and did the analysis as required for the project. Photographs were taken and relevant readings were recorded for documentation & project report.
Data collection includes all the relevant and appropriate data required for the completion of the project. This is of two kinds, Primary data and Secondary data. Primary data includes all the data which I have collected from the crankcase line such as component flow path, dent prone areas on the cover & joint faces, dimensions of the cone plugs and actual dents on KSPG components during the trial PP1 before the mass production of this new model. Some data was collected from the metallurgical lab after hardness inspection of cone plugs and some data was collected from engine assembly.
Apart from this I have also used some data from the department itself as a secondary data. It includes the quotations from vendors, process sheets, PQCS-I & II, plug cone drawings, operation standards, defect flow sheets etc. This collection has been shown in the annexure attached ahead.                                  
These all were the samples that I have taken for the study to complete my project in a better way. I decided to choose this study material from our company itself because this was best and comprehensive according to the executives and the line leaders who themselves have designed it so far. So it was very easy for them to teach me about that. Also it is very clear from the fact that the current documentation is better because the production target was getting achieved very well.

 


 

1) THE PDCA APPROACH: -

Among the most widely used tools for continuous improvement is a four-step quality model-the plan-do-check-act (PDCA) cycle, also known as Deming cycle or Shewhart cycle.




Plan- Identify an opportunity and plan for change.
Do- Implement the change on a small scale.
Check- Use data to analyze the results of the change and determine whether it made a       
difference.
Act-If the change was successful, implement it on a wider scale and continuously assess                 
your results. If the change did not work, begin the cycle again.



this approach were incorporated while implementing the countermeasures. It helped in the uninterrupted

flow of project activities. It is a result oriented methodology with side by side analysis of the result. It helps as a perfect effectiveness and improvement monitor. It provides us with appropriate ideas and concrete steps to avoid failures. It is a complete
quality analysis + control package with minimum discrepancies. That is why it is sometimes referred to as root cause of all improvements.
As a whole the PDCA methodology was of immense help during my stint of seven months as an industrial project trainee.

MARKET DETAILS OF AUTOMOBILE INDUSTRY:-


Automobile Industry is one of the few industries which have shown a continuous rapid growth since the industrial revolution in early 20th century. Also it has grown within itself, with the no. of manufacturing companies and types of vehicles increasing every year. Indian automobile industry is no exception with most of the major companies of the world investing in INDIA. With the Indian economy on boom, even the domestic companies are making rapid strides and competing with the international ones. The dramatic influence that automakers have on global economy is one of the indications of how widespread and significant this industry has become.
                                  The globalization of the Indian automobile industry continues, and their collaboration with foreign companies is flourishing. Gradual changes in the Indian economy and rising disposable income of the people is resulting in increased motorization. Global connections are seen as an effective way to respond to this trend, and will continue to multiply as the world’s automobile industries try to meet the increasing demands in a growing number of markets.
The main reasons for this exponential growth and revolution in Indian automobile industry (especially two-wheelers) are:-



  1. Government’s initiative on rural roads and better connectivity with major towns and cities.
  2. Improved agricultural performance.
  3. Upward trend of purchasing power in the hands of rural people.
  4. Better understanding between the world economies resulting in free and easy trade.
  5. Increasing trend of cooperation between world class companies in the field of automobile industry with an approach to reduce the costing.
