OVERVIEW
INDIAN AUTOMOBILE INDUSTRY
Over a period of more than two decades the Indian Automobile industry has
been driving its own growth through phases. The entry of Suzuki Corporation in
Indian passenger car manufacturing is often pointed as the first sign of India
turning to a market economy. Since then the automobile sector witnessed
rapid growth year after year. By late 90’s the industry reached self-reliance in
engine and component manufacturing from the status of large scale importer.
With comparatively higher rate of economic growth rate index against that of
great global powers. India has become a hub of domestic and export business.
The automobile sector has been contributing its share has been contributing its
share to the shining economic performance of India in recent years.
With the Indian middle class earning higher per capita income, more
people are ready to own private vehicles including cars and two-
wheelers. Product movements and manned services have boosted in
the sales of medium and sized commercial vehicles for passenger and
goods transport. Side by side with fresh vehicle sales growth, the
automotive components sector has witnessed big growth. The domestic
auto components consumption has crossed rupees 9000 crores and an
export of one half size of this figure
As per Society of Indian Automobile Manufacturers (SIAM) the market share of
each segment of the industry is as follows:
ABOUT YAMAHA MOTORS
HISTORY
Yamaha's history goes back over a hundred years to 1887 when
Torakusu Yamaha founded the company, which began producing
reed organs. The Yamaha Corporation in Japan (then Nippon Gakki
Co., Ltd.) has grown to become the world's largest manufacturer of
a full line of musical instruments, and a leading producer of
audio/visual products, semiconductors and other computer related
products, sporting goods, home appliances and furniture, specialty
metals, machine tools, and industrial robots.
The Yamaha Motor Corporation, Ltd., begun on July 1, 1955, is a
major part of the entire Yamaha group, but is a separately
managed business entity from the Yamaha Corporation. The
Yamaha Motor Corporation is the second largest manufacturer of
motorcycles in the world. Yamaha Motor Corporation owns its
wholly-owned subsidiary in the U.S. called Yamaha Motor
Corporation, USA, that is handling not only motorcycles, but also
snow mobiles, golf carts, outboard engines, and water vehicles,
under the brand name of Yamaha as well.
In 1954 production of the first motorcycles began, a simple 125cc
single-cylinder two-stroke. It was a copy of the German DKW
design, which the British BSA Company had also copied in the
post-war era and manufactured as the Bantam.
About India Yamaha Motor Pvt. Ltd.
Yamaha made its initial foray into India in 1985. Subsequently,
it entered into a 50:50 joint-venture with the Escorts Group in
1996. However, in August 2001, Yamaha acquired its remaining
stake becoming a 100% subsidiary of Yamaha Motor Co., Ltd,
Japan (YMC). In 2008, Mitsui & Co., Ltd. entered into an
agreement with YMC to become a joint investor in the
motorcycle manufacturing company "India Yamaha Motor
Private Limited (IYM)".
IYM operates from its state-of-the-art-manufacturing units at
Surajpur in Uttar Pradesh and Faridabad in Haryana and
produces motorcycles both for domestic and export markets.
With a strong workforce of more than 2,000 employees, IYM is
highly customer-driven and has a countrywide network of over
400 dealers.
MANUFACTURING
India Yamaha Motor’s manufacturing facilities comprises of 2 state-of-the-art
Plants at Faridabad (Haryana) and Surajpur (Uttar Pradesh). The infrastructure
at both the plants support of motorcycles and its parts for the domestic as well
as overseas market. It has In-house facility for Machining, Casting, Welding
process as well as finishing processes of Electroplating and Painting till the
assembly line.
The stringent Quality Assurance norms ensure that its motorcycles meet the
reputed International standard of excellence in every sphere.
RAW MATERIAL:-
The primary raw materials used in the manufacture of the body of motorcycle
are metal, plastic and rubber. The motorcycle frame is composed almost
completely of metal. The frame may be overlaid with plastic. The tires are
composed of rubber. The seat is made from a synthetic substance, such as
polyurethane.
The cylinder piston, made of aluminium alloy is an essential component of
engine. It is fitted with piston rings made of cast iron. The crankshaft and
crankcase are made of aluminium. The engine also contains a cylinder barrel,
typically made of cast iron or light alloy.
THE MANUFACTURING PROCESS:-
1. Raw materials as well as parts and components arrive at the
manufacturing plant by truck. As part of just-in-time delivery system on
which many plants are scheduled, the materials and parts are delivered at
the place where they are used or installed.
2. Manufacturing begins in the weld department with computer-controlled
fabrication of the frame from high strength frame materials. Components
are formed out of tubular metal and/or hollow metal shells fashioned from
sheet metal shells fashioned from sheet metal. The various sections are
welded together. This process involves manual, automatic and robotic
equipment.
3. In the plastic department, small plastic resin pellets are melted and
injected into molds under high pressure to form various plastic body trim
parts. This process is known as injection molding.
4. Plastic and metal parts and components are painted in booths in the paint
department using a process known as powder-coating. A powder coating
apparatus works like a large spray-painter, dispersing paint through a
pressurized system evenly across the metal frame.
5. Painted parts are sent via overhead conveyors or tow motor to assemble
department where they are installed on the frame of the motorcycle.
6. The engine is mounted in the painted frame, and various other
components are fitted as the motorcycle is sent down the assembly line.
7. Wheels, brakes, wiring cables, foot pegs, exhaust pipes, seats, saddlebags,
light, radios and hundreds of other parts are installed on the motorcycle
frame.
QUALITY CONTROL:-
At the end of the manufacturing line and assembly line, quality control
inspectors undertake a visual inspection of the motorcycle and its part’s
finishing, painted finish and fit of parts. The quality control inspectors also feel
the motorcycles with gloved hands to detect any bumps or defects in the finish.
Each motorcycle is tested on a dynamometer.
Inspectors accelerate the motorcycle from 0-60mph. During the acceleration,
the “dyno” tests for acceleration and braking, shifting, wheel alignment,
headlight and taillight alignment and function, horn function and exhaust
emissions. The finished product must meet international standards for
performance and safety. After the dyno test, a final inspection is made of the
completed motorcycle.
FARIDABAD PLANT
The manufacturing unit of Faridabad plant constitutes Casting, Machining,
Welding, Heat treatment and Painting of parts of two wheelers of IYM.
Following are the parts of two wheelers manufactures in Faridabad Plant of
IYM:-
1. Gear
2. Axle Main
3. Cylinder Head
4. Cylinder body
5. Crank
6. Crankcase
7. Cover crankcase
8. Cam and Cam shaft
9. Connecting rod
GEAR
GEAR BLANK from the vendor is brought to the Faridabad plant for
manufacturing of gears. Then it is passed through the following processes:-
Turning, facing, boring and chamfering
Hobbing
Broaching
Marking
Washing
Shaving
Heat treatment
Hobbing
Hobbing is a machining process for making gears, splines, and spockets on a
hobbing machine, which is a special type of milling machine. The teeth or
splines are progressively cut into the gear blank by a series of cuts made by a
cutting tool called hob. Compared to other gear forming processes it is
relatively inexpensive but still quite accurate, thus it is used for broad range of
parts and quantities.
It is most widely used gear cutting process for creating spur and helical gear
and more gears are cut by hobbing than any other process since it is relatively
quick and inexpensive.
USES
Hobbing is used to make following types of finished goods:
Cycloid gear
Helical gears
Involute gear
Ratchets
Splines
Sprockets
Spur gears
Worm gears
Hobbing is used to produce most throated worm wheels but certain tooth
profiles cannot be hobbed. If any portion of hob profile is perpendicular to axis
then it will have no cutting clearance generated by usual backing off process
and it will not cut well.
BROACHING
For very large gears or splines a vertical broach is used. It consists of a vertical
rail that carries a single tooth cutter formed to create the tooth shape. A rotary
table and a Y axis are the customary axes available. Some machines will cut to a
depth on the Y axis and index the rotary table automatically. The largest gear
are produced on these machines.
Other operation such as broaching work particularly well for cutting teeth on
the inside. The downside to this is that it is expensive and different broaches
are required to make different sized gears. Therefore it is mostly used in very
high production runs.
MARKING
Marking is done on the Primary Gear and Gear Balance Weight. In this process
in mark is made on a certain distance from the centre of the gear on both types
of gear so that at time of assembly all the gear should be properly mounted
such as no misalignment is present in gear assembly, otherwise the
transmission system of vehicle fails during the operation.
CAMSHAFT
Camshafts can be made out of several different types of material. These
include Chilled iron casting and Billet steel.
Chilled Iron Casting: this is a good choice for volume production. A chilled iron
camshaft has a resistance against wear because the camshaft lobes have been
chilled, generally making them harder.
Billet Steel: when a high quality camshaft is required, engine builder and
camshaft manufacturers choose to make the camshaft from steel billet. One
example being EN40b. When manufacturing a camshaft from EN40b, the
camshaft will also be heat treated via gas nitriding, which changes the micro-
structure of the material. It gives a surface hardness of 55-60 HRC. These types
of camshafts can be used in high-performance engines.
Processes
Various process involve in the manufacturing of cam shaft according to
operating machines are:-
Facing
Turning operation
Keyway drilling and tapping operation

HEAT TREATMENT
Heat treating is a group of industrial and metal working processes used to alter
the physical and sometimes chemical properties of a material. The most
common application is metallurgical. Heat treatments are also used in the
manufacture of many other materials such as glass, Heat treatment involves
the use of heating or chilling normally to extreme temperatures to achieve a
desired result such as hardening or softening of material. Heat treatment
techniques include annealing, case hardening, precipitation strengthening,
tempering and quenching. It is noteworthy that while the term heat treatment
applies only to processes where heating and cooling are done for specific
purpose of altering properties intentionally, heating and cooling often occur
incidentally during other manufacturing processes such as hot forming or
welding.
TECHNIQUES:
The heat treatment techniques used for manufacturing of parts of two wheeler
in Faridabad plant are:-
Annealing
It consists of heating a metal to a specific temperature and then cooling at a
rate that will produce a refined microstructure. It is often used to soften a
metal for cold working to improve machinability or to enhance properties like
electrical conductivity
Normalizing
Normalizing is a technique used to provide uniformity in grain size and
composition throughout an alloy. The term is often used for ferrous alloys that
have been heated above the upper critical temperature and then cooled in
open air.
Stress relieving
Stress relieving is a technique to remove or reduce the internal stresses created
in a metal. These stresses may be caused in a number of mays, ranging from
cold working to non-uniform cooling. Stress relieving is usually accomplished by
heating a metal below the lower critical temperature and then cooling
uniformly.
Aging
Some metal are classified as precipitation hardening metals. When a
precipitation hardening alloy is quenched, its alloying elements will be trapped
in solution, resulting in a soft metal. A “solutionized” metal will allow the
alloying element to diffuse through the microstructure and form intermetallic
particles. These intermetallic particles will nucleate and fall out solution and act
as a reinforcing phase, thereby increasing the strength of the alloy. Alloys may
age “naturally” meaning that the precipitates form at room temperature, or
they may age “artificially” when precipitates only form at elevated
temperatures. In some applications, naturally aging alloy may be stored in a
freezer to prevent hardening until after further operation-assembly of rivets,
for example, may be easier with a softer part.
Quenching
Quenching is a process of cooling a metal very quickly. This is most often done
to produce a martensite transformation. In ferrous alloys, this will often
produce a harder metal, while non-ferrous alloys will usually become softer
than normal.
