ABSTRACT
The objective of the project was to understand the current layout, Ergonomics, VAA and
NVAA, working cycle of OP-10 and OP-20, process/material flow and to suggest
improvements and changes to extend the current production limit at the differential assembly
line by considering all aspects of WCM. For this we have to understand the operator needs,
Area constraints, cost constraints, ergonomic laws, WCM, sequence of operations done at
assembly line, so that they can contribute their valuable inputs while suggesting changes in
best possible way.
The first part of my training started on Feb. 2nd which involved understanding the Process
flow, layout of transmission shop, Parts machined, Types of machining, Machines used, and
basics of production system at FIAT Powertrain department. For this I used pillar boards as
the primary source of information for my study also the WCM gallery proved very helpful
and discussed topics with Mr. Shivakumar. Along with detailed study of lean manufacturing
system focus was mainly on basics of Industrial Engineering.
The next part of my project was to understand and analyse the operations and activities at
differential assembly line and conducting detailed study by taking clues from study done so
far.
The most important part was to analyse the data and information and propose different
options available to us to adopt, considering many different aspects.

ABOUT THE COMPANY
FIAT (Fabbrica Italiana Automobili Torino) is an Italian automaker whichproduces Fiat branded cars, and is part of Fiat Chrysler Automobiles through itssubsidiary FCA Italy S.p.A.., the largest automobile manufacturer in Italy. The company, FiatAutomobiles S.p.A., was formed in January 2007 when Fiat reorganized its automobilebusiness, and traces its history back to 1899 when the first Fiat, or Fabbrica ItalianaAutomobili Torino automobile, was produced.
FOUNDER: Giovanni Agnelli
PRESIDENT: John Elkann CEO: Olivier François
FIAT IN EUROPE
Fiat's main market is European one, mainly focused in Italy. Historicallysuccessful in citycars and supermini sector, currently Fiat has a range of models focused onthose two segments (in 2011, those accounted for the 84% of its sales). Fiat does not currentlyoffer any large family car, or an executive car.
Fiat's share of the European market shrank from 9.4 per cent in 2000 to 5.8 per cent in the
summer of 2004. At this point Sergio Marchionne was appointed as Fiat Chief Executive. ByMarch 2009 their market share had expanded back to 9.1%.
Fiat's built their five-story Lingotto plant in 1915 through 1918, at the time it was Europe's
largest car manufacturing plant. Later the Mirafiori plant was built, also in Turin. To prepare
for production of the all new Fiat 128, Fiat opened their Rivalta plant in October 1968. Until
the 128 could enter production, the plant was used to build sports versions ofthe 850 and 124 as well as parts for the Fiat Dino.
Fiat current range of passenger car engines comprises eleven units, eight petrols and threediesels. Current range of models is the following:
City car: Fiat 500, Fiat Panda
Supermini: Fiat Punto
Compact car: Fiat Bravo, Fiat Linea
Mini MPV: Fiat 500L
Large MPV: Fiat Freemont (rebadged Dodge Journey)
Mini SUV: Fiat Sedici (developed with Suzuki with its twin Suzuki SX4)

FIAT IN UNITED STATES
Fiat has a long history in United States. In 1908, the Fiat Automobile Co. wasestablished in the country and a plant in Poughkeepsie, N.Y., began producing Fiats a yearlater. These luxury cars were produced long before Chrysler Corp. started in 1925. Fiat wassometimes used as a jocular backronym for 'Fix it again Tony', referring to poor reliabilityand problems, such as rust, which some Fiat owners in the United States encountered in the1970s and 1980s. Partly as a result, Fiat sales in the US fell from a high of 100,511 cars in1975 to 14,113 in 1982. In 1983, Fiat left the United States car market with a reputation forpoor quality cars. However, Fiat has made significant improvements since then.
In January 2009, the Fiat Group acquired a 20% stake in US automaker Chrysler LLC. Thedeal saw the return of the Fiat brand to North America after a 25-year absence. The first Fiat-branded model to appear in the US was the popular Fiat 500 city car. The Fiat 500 model isbuilt at Chrysler's assembly plant in Toluca, Mexico which currently makes also the DodgeJourney and Freemont crossovers.
FIAT IN ASIA
Fiat's presence in Chinese market is poor compared to its European, Japanese,and Korean and American rivals. At the beginning of 2012, Fiat was only importing FiatBravo and Fiat 500 model. However, in 2012 Fiat and GAC opened a Joint Venture plant toproduce the first Fiat vehicle specifically developed for Chinese market ever: the FiatViaggio, a compact car derived by another model of Fiat SpA group, the Dodge Dart (in turnderived by another Fiat Group car, the Alfa Romeo Giulietta).
Fiat currently offers to Japanese consumers the 500 in both coupe and convertible body styles,and the Panda. Both vehicles are in compliance with Japanese Governmentdimension affording the Japanese public to purchase a non-Japanese vehicle without having topay an annual tax for driving a car that exceeds the regulations.
Fiat is also present in Indian market since 1948. Current presence is in Joint Venturewith Tata Motors, although current car sales (Fiat is currently offering the Fiat Punto and FiatLinea) are poor (approx. 20k units in 2011).
MOTORSPORT
In 1971 the Fiat 124 Sport Spider was prepared for the World RallyChampionship when Abarth became involved with its production and development and from1972 had relative success with two wins in 1972, one in 1973 and won 1st, 2nd and 3rd in the1974 Portuguese TAP Rally.

The Fiat 131 Abarth was a very successful rally car replacing the 124. Between 1976 and1981 the Fiat 131 won 18 World Rally Championship events, and winning the WRC threetimes: in 1977, 1978, and in 1980.
Lancia took over the role of motorsport for the Fiat Group during the 1980s. After a longbreak of factory-supported entries, in 2003 a Fiat Punto S1600 won the Italian RallyChampionship, and 2006 the Fiat Grande Punto S2000 won the FIA European RallyChampionship, followed by three successive wins in 2009, 2010 and 2011.

for every need that are also stylish, fun to drive and surprisingly functional. Fiat creates carswith passion to make people’s lives better.
ENVIRONMENT
One of the most important pillars of brand Fiat is its commitment tosustainable mobility. The Group keeps introducing innovative solutions in every operatingregion for both conventional engine technologies and alternative fuels and propulsionsystems. Examples of already available eco-friendly technologies are TwinAir, Multijet II,Multiair and the largest natural gas range in Europe. As a result, average CO2 emissions fromFiat cars sold in Europe decreased by 13% in 2013 compared with 2007. The launch of Fiat500e in USA, a zero-emission electric vehicle, is also an evidence of the environmentalcommitment of the brand. In addition to the new technologies, Fiat believes that theenvironmental impact of vehicles is strongly influenced by consumer’s driving behavior.Fiat continues to invest in Eco: Drive, an application that improves driving styles by givingpersonalized recommendations for reducing emissions, saving fuel and quantifying economicadvantages.
COMPANY HISTORY
1899-1911FIAT was foundedOn 11 July 1899 at Palazzo Bricherasio, the company charter of Società Anonima FabbricaItaliana Automobili Torino (Italian Automotive Factory in Turin) was signed. Among themembers of the Board of Directors, Giovanni Agnelli stood out in the group of investors andwon recognition for his determination and strategic vision. In 1902 he became the ManagingDirector of the company.
The first factory was openedThe first factory was opened in 1900 in Corso Dante. 150 workers were employed there andproduced 24 cars, among which the 3/12 was HP, not yet fitted with reverse gear. The FIAT®logo, oval on a blue background and designed by Biscaretti, was adopted in 1904.
First wins in the racesThe first Car Tour of Italy saw 9 Fiat cars arrive at the finish line. The first real competitioncar, a 24 HP driven by Vincenzo Lancia, won the Sassi-Superga uphill race in 1902. GiovanniAgnelli himself ran in the Second Tour of Italy and set a record in an 8 HP.

1912-1925Fiat expands to new sectorsIn the meantime Fiat expanded its activities to the steel industry, the railway, electricity andpublic transportation lines. Fiat Lubrificanti was established and the first Italian subsidiarywas opened in Russia. When the War broke out, company production was almost entirelyaimed at supplying the army.
Development of the CompanyThe policy adopted by the company was to develop industrial mass production. Massproduction was launched as the only way to curb the prohibitive prices of cars. During aphase of increasing consumption, Sava, a holding company was set up to promote instalmentplans for purchasing cars. IFI, Istituto Finanziario Industriale, was also established at thattime.
1926-1938The new carsIn 1934 and 1936 two cars came out and were destined to an enormous public: the “Balilla”,also called “Tariffa minima” due to its low consumption of fuel, and the “Topolino”, thesmallest utilitarian car in the world, which was produced until 1955.
The Mirafiori factoryIn 1937 works started for the great Mirafiori plant, which introduced the most advancedprinciples of industrial organisation and confirmed company focus on mass production.
1978-1990The Robogate systemIn 1978 the “Robogate” system was created, the new flexible robotized system for assemblingthe bodywork. It was the road to innovation and the automation of production.
The holding configurationIn 1979 the auto sector was set up as an independent company: Fiat Auto S.p.A., whichincluded the brands Fiat, Lancia, Autobianchi, Abarth, Ferrari. The Ferrari brand wasacquired at 50% initially, a share that later rose to 87%. In 1984 the company also took overAlfa Romeo (following by Maserati acquisition - a prestigious sports car brand - in 1993).
The Fiat Panda and the Fiat UnoIn 1980 a new utilitarian was styled by Giugiaro for Fiat and was called Panda. Two yearslater the car that would become the emblem of Fiat Auto’s renewal was born: the Fiat Uno. It
Page | 11
featured radical innovations in its electronics, choice of materials and the use of a cleanengine: the 1000 Fire.
1991-2003The new cars of the 1990sAfter the debut of the Fiat Tempra in 1990, the 500 came out in 1991. Two years later, in1993, it was the moment of Fiat Punto (named “Car of the Year” in 1995) and Fiat Coupé,with bodywork designed by Pininfarina and Centro Stile Fiat.
Other popular carsWith Fiat Ulysse, which came out in 1994, the company made its entry in a sector that wasprogressively expanding: the SUV. 1995 saw the debut of the Barchetta, the Fiat Bravo andBrava, followed the next year by Fiat Marea and Marea WE, and in 1997 Fiat Palio.
Changes at the top and a new registered officeIn 1996 Giovanni Agnelli became the Honorary President of the Fiat Group and CesareRomititook the office of CEO. In 1997 the parent company left its premises in Corso Marconi andmoved to the Palazzina Fiat of Lingotto, which in the meantime had been converted into aTrade Fair and Convention Complex.
2004-2007The restyling of the logo on Fiat IdeaFiat Idea was the first MPV created by Fiat but also the first car with the task ofcommunicating the brand’s new 'mission': Fiat Idea displayed the round logo, renewed andproposed by Centro Stile Fiat to evoke the emblem designed to celebrate the Company’s100th Anniversary.It was also meant to get across the most significant change in Fiat cardesign: more attention to high-tech content and intelligent solutions designed to simplifyseveral aspects of daily life in the car.
Multijet enginesFuel saving and top performing, this engine proved a real success factor on the new Fiat carmodels.The new system – born of the evolution of the ‘Common Rail’ principle – is the basisof the new second-generation Fiat engines: the small 1.3 Multijet 16v, the sporty 1.9 Multijet120 and 150 bhp and the powerful 1.4 90 bhp.
Three years of new modelsThe years 2004-2006 were an extremely busy time for the Turin company, which, following aprofound change in corporate culture and mentality, focused on a continuous, rapid overhaulof its products, on technological research, on the quality of its designs and on a new,constructive relationship with the customer.During these years, this new philosophy gave riseto a series of new models, and some restyling of older models: from the restyling of the FiatIdea Model Year, Seicento MY and Stilo MY to the new Multipla and the launch of the Panda
Page | 12
4x4, in 2004; 2005 began with the launch of the new Croma, designed by Giugiaro, the new600 (celebrating its 50th anniversary), and the Grande Punto - beautiful, solid andexciting.2006 saw the launch of the New Doblò and Sedici, the 4x4xTUTTI for city and off-road driving, and the official car of the 2006 Olympic Winter Games, while the Panda MY2007 range was extended and overhauled.
The debut of the new logo on the Bravo2007 began with the launch of the Bravo – preceded by the first ever institutional Fiat blog.Bravo is the first car to sport the new Fiat logo as a tangible sign of the company’sturnaround. The new Bravo is a successful blend of beauty and substance, destined to becomea benchmark for the segment.
500 launchOn July 4 2007, exactly 50 years after the launch of the original 500, the new Fiat 500 madeits debut in Turin.It is the first ‘small’ car with an individualistic concept,allowing theconsumer to tailor-make their 500 with more the 500000 available variants. Following itslaunch, the 500 won numerous awards, such as the European Car of the Year In2008.Numerous limited editions and versions have been created: new Fiat 500 by GQ, Gucciand Diesel just to name a few.
2008-2013Twin Air–revolutionary technologyIn July 2010, Twin Air-the first of a new family world’s high tech two-cylinder engines madeby FPT-Fiat Powertrain Technologies was launched through Fiat 500 model.This technologyimplements the revolutionary MultiAir system combined with specific fluid dynamicsoptimised for maximum fuel efficiency. Furthermore,by taking the concept of downsizing tothe extreme and masterfully tuning the basic mechanics, the new Twin Air engine family-delivering from 65 to 105 HP-emits 30% less CO2 than an engine of equal performance.
Fiat becomes more environment-friendlyFiat cars becomes more eco-friendly with low pollutant and CO2 emission levels. With FiatEco-drive, Methane engines, Start&Stop, MultiJet, TwinAir, the Fiat Group’s sustainabilitystrategy has resulted in a combination of conventional and alternative technologies. BrandFiat made also its move in the electric cars field with the launch of Fiat 500 E (with 0 CO2emissions) on July 2013 in USA.
Fiat growthFiat has brought its passion not only to the "Old Continent", but also in Northern America-with the launch of Fiat in USA in 2009 and Asia. In Asia we highlight the creation of the newjoint venture GacFiat in 2010.After the importation of Fiat Bravo, Fiat 500 and Fiat Freemont,in 2012 it was launched Viaggio-first tailormade sedan for China market-produced in GacFiatjointventure factory located in Changsha. This factory adopts the standards of World ClassManufactory as all the factories from Fiat and Chrysler.

TRANSMISSION SHOP: MACHINING
Page | 20
MACHINING
Soft Machining: Machining the parts prior to heat treatment. All large and deep cuts aredone during soft machining when part is comparatively less hard.
Hard Machining: Generally semi-finishing and finishing is done in hardened state. Deppcuts are usually avoided.
Various Machining Processes :-
HOBBING: Hobbing is a machining process for gear cutting, cutting splines, andcutting sprockets on a hobbing machine, which is a special type of milling machine. The teethor splines are progressively cut into the work piece by a series of cuts made by a cuttingtool called a hob. Compared to other gear forming processes it is relatively inexpensive butstill quite accurate, thus it is used for a broad range of parts and quantities.
It is the most widely used gear cutting process for creating spur and helical gears and moregears are cut by hobbing than any other process since it is relatively quick and inexpensive.Hobbing uses a hobbing machine with two skew spindles, one mounted with a blank workpiece and the other with the hob. The angle between the hob's spindle and the work piece’sspindle varies, depending on the type of product being produced. For example, if a spur gearis being produced, then the hob is angled equal to the helix angle of the hob; if a helical gearis being produced then the angle must be increased by the same amount as the helix angle ofthe helical gear. The two shafts are rotated at a proportional ratio, which determines thenumber of teeth on the blank; for example, if the gear ratio is 40:1 the hob rotates 40 times toeach turn of the blank, which produces 40 teeth in the blank. Note that the previous exampleonly holds true for a single threaded hob; if the hob has multiple threads then the speed ratiomust be multiplied by the number of threads on the hob. The hob is then fed up intoworkpiece until the correct tooth depth is obtained. Finally the hob is fed through theworkpiece parallel to the blank's axis of rotation. Up to five teeth can be cut into theworkpiece at the same time. Often multiple gears are cut at the same time.

HONING: Honing or to "Hone" is an abrasive machining process that produces a precisionsurface on a metal workpiece by scrubbing an abrasive stone against it along a controlledpath. Honing is primarily used to improve the geometric form of a surface, but may alsoimprove the surface texture.
Typical applications are the finishing of cylinders for internal combustion engines, airbearing spindles and gears. There are many types of hones but all consist of one or moreabrasive stones that are held under pressure against the surface they are working on.
SHAVING: The shaving process is a finishing operation where a small amount of metal issheared away from an already blanked part. Its main purpose is to obtain better dimensionalaccuracy, but secondary purposes include squaring the edge and smoothing the edge. Blankedparts can be shaved to an accuracy of up to 0.025 mm (0.001 in).
CONTOUR GRINDING: Grinding Machines are also regarded as machine tools. Adistinguishing feature of grinding machines is the rotating abrasive tool. Grinding machine isemployed to obtain high accuracy along with very high class of surface finish on theworkpiece. However, advent of new generation of grinding wheels and grinding machines,characterised by their rigidity, power and speed enables one to go for high efficiency deepgrinding (often called as abrasive milling) of not only hardened material but also ductilematerials. Some types of surface grinders are also capable of producing contour surface withformed grinding wheel.
SHOT PEENING: Shot peening is a cold working process used to producea compressive residual stress layer and modify mechanical properties of metals. It entailsimpacting a surface with shot (round metallic, glass, or ceramic particles) with force sufficientto create plastic deformation.
It is similar to sandblasting, except that it operates by the mechanism of plasticity ratherthan abrasion: each particle functions as a ball-peen hammer. In practice, this means that lessmaterial is removed by the process, and less dust created. Peening a surface spreads itplastically, causing changes in the mechanical properties of the surface. Its main application isto avoid the propagation of micro cracks from a surface. Such cracks do not propagate in amaterial that is under a compressive stress; shot peening can create such a stress in thesurface.
Shot peening is often called for in aircraft repairs to relieve tensile stresses built up in thegrinding process and replace them with beneficial compressive stresses. Depending on thepart geometry, part material, shot material, shot quality, shot intensity, shot coverage, shotpeening can increase fatigue life up to 1000%.
Plastic deformation induces a residual compressive stress in a peened surface, along withtensile stress in the interior. Surface compressive stresses confer resistance to metalfatigue and to some forms of stress corrosion. The tensile stresses deep in the part are not as

problematic as tensile stresses on the surface because cracks are less likely to start in theinterior.
COLD SPLINE ROLLING: The total forming effort needed to generate splines in solidmaterials is broken down into numerous forming steps spread along the entire cylindricallength of the zone to be formed. As its name implies, this technique applied is a strictlyforming (rolling) process during which no chip forming is involved.
PARTS
INPUT SHAFT
The automobile's engine crankshaft turns and creates power. This mechanical energy mustfirst go through the transmission gearbox before it eventually reaches the wheels. The firstcomponent to receive this energy is the input shaft. It can be engaged or disengaged throughthe mechanism of the clutch. Typically in a rear-wheel drive car, the input shaft is designed tolay along the same line as the output shaft, forming what seems like a singular component thatis sometimes called a main shaft.
Page | 23
Fig. Input and Output Shaft in correct configuration.
OUTPUT SHAFT
The final component that carries the power out of the transmission gearbox and on to thewheels is the output shaft. A set of transmission gears parallel to those on the counter shaft arearranged along the output shaft; it is driven by the counter shaft through these gears. Bothoutput and counter shaft gears are usually already meshed but the output shaft gears are notpermanently attached to it. These gears are the ones actually shifted manually by the driver.Only the one gear selected is fastened and rotates the output shaft along with it, while theothers spin freely until another one is selected.

HEAT TREATMENT PROCESS
All parts (I/P, O/P Shaft, Ring Gear, 5th Gear) are mounted on a Nickel fixture on atrolley.
Mounted material enters furnace and the vacuum creation process starts and pressureis taken from 1000 millibar (Atm. Pressure) to 10 millibar. Vacuum is created so thatvery less air remains in chamber and hence no chance of oxidation in furnace.
This furnace is an Electric furnace which is always at 960deg Celsius. When parts reach 960deg Celsius, Acetylene (C2H2) is diffused for 90sec and after
that Nitrogen (N2) if diffused alternately for 100sec.This cycles take place many timesand is known as carburising.
After carburising, hot parts are taken out and de-vacuum process is done.
After that depending upon material type oil or Gas quenching is done. After this tempering is done to parts. Parts are soaked at 170deg Celsius.
After tempering parts cool down slowly normally and are finally unloaded at end. After unloading metallurgical inspection is done.
MATERIALS AND QUENCHING MEDIUM
Parts are produced of two materials ;
1) 27MnCr5 Used for High Torque transmission (90 HP).
Require low cooling Rate. Gas Quenching is done.
2) 20MnCr5
Used for Low Torque transmission (75 HP). Require High cooling Rate. Oil Quenching is done.
CARBURISING
PROCESS FUNDAMENTALS
Hydrocarbon thermal cracking at low pressure. C2H2- 2C + H2 Alternate injection of hydrocarbon gas and neutral gas.
Number and duration of duration of steps determined by case depth required.
WHY ACETYLENE Vs. PROPANE ?
Gas consumption/ Load is less. No exhaust gas emission measures required.
Nature of by-products is easily cleanable (Good for maintenance). Acetylene By-products Dry, Soot-like-by product.
Page | 40
Propane By-products Tar like, Glue Like of High Viscosity.
ADVANTAGES OF VACUUM CARBURISING
Fast Carbon Transfer. No Surface Oxidation. Good Case depth uniformity. Integration into manufacturing. Little consumption of carburising Gas. No formation of furnace atmosphere. High Carburising temperatures possible.
HARDENING
Process:
- Heating steel to proper austentising temperature.- Soaking at this temperature to get a fine grained and homogenous Austentite.- Cooling Steel at a rate faster than its critical cooling rate.- Austentite transforms to martensite and steel becomes hard.
TEMPERING
Process:
- Heating Steel to proper austentising temperature.- Soaking at this temperature to get a fine grained and homogenous Austentite- Cooling normally very slowly- Tempered Steel
Why To Do Tempering?
- To relieve quenching stress developed during hardening.- To restore ductility and toughness with decrease in hardness and strength.- To improve dimensional stability by decomposing retained Austentite.- To improve magnetic properties by transforming non-magnetic retained Austentite.-
GAS QUENCHING
2 turbines of Aluminium, 12 Blades each rotate at 3000 RPM. 2 Gas to Liquid Heat Exchangers.
Heat Exchangers are made of copper tubes installed on a light removable frame,placed between chamber inner wall and screens.
After Quenching, High pressure gas is exhausted to atmosphere.
