AbstractAs we mentioned earlier that our main purpose for this internship/ industrial training was to gain knowledge and get perspective regarding the operation of a mega production facility. Our wishes were more than answered when HONDA CARS INDIA Ltd. provided us with an opportunity like this to intern at the Tapukara plant. This internship has been really an eye opener for us all. We were placed in the Utility dept. and primarily toured all the sub divisions coming under them. Utility dept. was responsible for mainly running and aiding the plant behind the scenes. It provided and helped in maintenance of the 4 major industrial utilities i.e. electricity, water, natural gas & air. Utility dept. does not manufacture any vehicle but without their aid & behind the scenes hard work even manufacturing dept. can do nothing. We also had the great opportunity to observe different departments other than the Utility. It was the first time that we had seen a mega factory up close & personal. One thing which struck us was that how such a giant manufacturing plant operates, it is so huge that it has several departments some of which functions individually as a small autonomous unit itself. Each dept. can have many sections as well, in order to manage them there are section heads and above them there is a consolidated head called the Head of Dept. (H.O.D) . A plant this big is like an enlarged machine which has individual intelligent parts which function individually and together to create a final product i.e. a HONDA car.

HONDA Cars India Ltd.- Brief ProfileHonda Cars India Ltd(HCIL) is a subsidiary of theHondaof Japan for the production, marketing and export of passenger cars in India. Formerly known as Honda Siel Cars India Ltd, it began operations in December 1995 as a joint venture between Honda Motor Company and Usha International of Siddharth Shriram Group. In August, 2012, Honda bought out Usha International's entire 3.16 percent stake for1.8 billion in the joint venture. The company officially changed its name to Honda Cars India Ltd (HCIL) and became a 100% subsidiary of Honda.HCIL's first manufacturing unit was set up at Greater Noida, U.P in 1997. The plant is spread across 150 acres and has an annual production capacity of 120,000 units. HCIL's second plant in Tapukara is the first car manufacturing plant in the state of Rajasthan. The state-of the art Power train and Press shop in Tapukara plant have been operational since September 2008. This facility is spread over 450 acres and has an annual production capacity of 120,000 units. HCIL started the production of cars from its Tapukara Plant from February 2014.

Utility DepartmentUtility dept. as we mentioned earlier is the dept. responsible for maintaining & supplying water, electricity, natural gas & air to the plant where they are utilized in production. The 4 major utilities in industry are electricity, water, natural gas & air. Without the utilities a plant cannot produce because it's the key component on which all the machines and tools operate which are then used to convert raw material into finished goods. The utility dept. has different kinds of treatment plants, substations, switch house, compressor houses, diesel generator house etc. Basically it deals with energy and its different forms. It's like the fuel that is required to run a machine, in this case utility dept. is the fuel & the whole plant is the machine.

Compressor HouseDefinition: By definition a compressor house is that area of the plant that supplies clean and dry compressed air to different departments in the plant for further use. There are namely two compressor houses in the Honda plant, they are compressor house-1 & compressor house-2.

Importance & Uses of Compressed Air: Compressed air, commonly called Industry's Fourth Utility, is air that is condensed and contained at a pressure that is greater than the atmosphere. The process takes a given mass of air, which occupies a given volume of space, and reduces it into a smaller space. In that space, greater air mass produces greater pressure.Industrial Plant Maintenance: Air tools, such as paving breakers, are used to fix cement floors, to open up brick walls for assorted service lines, and other comparable work. For other maintenance work, plants can use air-operated drills, screwdrivers, and wrenches, provided that the air outlets are well placed throughout the plant. Painting can be done using paint-spraying systems.On the Production Line: Pneumatic tools are convenient for industrial production because they have a low weight-to-power ratio, and they may be used for long periods of time without overheating and with low maintenance costs. Chipping and scaling hammers are used in railroads, oil refineries, chemical refineries, shipyards, and many other industries for general application. They are also used in the foundry for cleaning large castings, and to remove weld scale, rust, and paint in other industries. Pneumatic drills can be used for all classes of reaming, tapping, and drilling anytime that the work cannot easily be carried to the drill press and for all classes of breast drill work. These air-powered drills are also often used for operating special boring bars, and in emergencies, for independent drive of a machine tool where required horsepower is within their capacity.

List of Compressors: There are 6 compressors in compressor house-1 & general pressure requirement is around 6.5 bar. There are 3 compressors in compressor house-2 & general pressure requirement is around 5.5 bar. Compressors from 2 companies are employed in the plant, they are Atlas Copco & Ingersoll Rand. All Atlas Copco compressors are screw type & are needed where the pressure requirement is high. All Ingersoll Rand compressors are Centrifugal type & are needed where higher amount of air is required. Following is the list of compressors employed at the plant.

Diesel Generator HouseDefinition: A Diesel generator house or D.G. House as it's called is that unit of the plant which houses the diesel generators to provide electricity whenever the electric supply from the main power grid fails or during a power cut.D.G. House in the plant consists of 5 diesel generators. Adiesel generatoris the combination of adiesel enginewith anelectric generator(often analternator) to generateelectrical energy. A diesel compression-ignition engine often is designed to run on fuel oil, but some types are adapted for other liquid fuels ornatural gas. The packaged combination of adiesel engine, ageneratorand various ancillary devices (such as base, canopy, sound attenuation,control systems,circuit breakers, jacket water heaters and starting system) is referred to as a "generating set" or a "genset" for short. Together these gensets can provide around 11 kV electric supply almost equivalent to grid but they are very expensive to run due to high consumption of fuel used.Generators Present: Out of the 5 gensets, 4 are from Cummins and 1 is from MAN. Out of the 4 gensets from Cummins, 2 can generate 1.2 MW & other 2 can generate 1.6 MW. They have speeds ranging around 1500 rpm. Cummins generators are utilizing a V-16 diesel engine which is liquid cooled as well as turbocharged. It also has 2 Fleetguard air filters for filtering purposes. It also has 4 fuel filters out of which 2 are ultra fine filters.

The last genset present is the genset from MAN. It's large genset that is capable of producing 2.5 MW. It's a pneumatic or air starter generator. Compared to agasoline("petrol") engine, diesel engines have very highcompression ratiosto improve engine efficiency. An electric starter powerful enough to turn a large diesel engine would itself be so large as to be impractical, thus the need for an alternative system. When starting the engine,compressed airis admitted to whichever cylinder has apistonjust overtop dead centre, forcing it downward.As the engine starts to turn, the air-start valve on the next cylinder in line opens to continue the rotation. As this goes on, fuel is injected into the cylinders, the engine is then under way and the air is cut off. This genset can run on diesel as well as on furnace oil. It's a low speed engines with speed ranging around 750 rpm.

132 KV Switch House & Substations

Introduction: The present-day electrical power system is A.C. i.e. electric power is generated, transmitted and distributed in the form of alternating current. The electric power is produced at the power stations which are located at favourable places, generally quite away from the consumers. It is delivered to the consumers through a large network of transmission and distribution. At many places in the line of the power system, it may be desirable and necessary to change some characteristic (e.g. voltage, A.C. to D.C., frequency, Power factor etc.) of electric supply. This is accomplished by suitable apparatus called sub-station. For example, generation voltage (11KV or 6.6KV) at the power station is stepped up to high voltage (say 220KV or 132KV) for transmission of electric power. The assembly of apparatus (e.g. transformer etc.) used for this purpose is the sub-station. Similarly, near the consumers localities, the voltage may have to be stepped down to utilization level. This job is again accomplished by a suitable apparatus called substation.

Types of Substations in Plant:Transformer sub-stations, sub-stations which change the voltage level of electric supply are called transformer sub-stations. These sub-stations receive power at some voltage and deliver it at some other voltage. Obviously, transformer will be the main component in such sub-stations. Most of the sub-stations in the power system are of this type.

Switching sub-stations, sub-stations that do not change the voltage level i.e. incoming and outgoing lines have the same voltage. However, they simply perform the switching operations of power lines.

Different Components of Substationa) Lightening Arrestors: Lightening arrestors are the instruments that are used in the incoming feeders so that to prevent the high voltage entering the main station. This high voltage is very dangerous to the instruments used in the substation. Even the instruments are very costly, so to prevent any damage lightening arrestors are used. The lightening arrestors do not let the lightening to fall on the station. If some lightening occurs the arrestors pull the lightening and ground it to the earth. In any substation the main important is of protection which is firstly done by these lightening arrestors. The lightening arrestors are grounded to the earth so that it can pull the lightening to the ground.

b) Earthing : The earthing practice is adopted at generating stations, sub-stations and lines should be in such a manner as to provide:1)Safety to personnel 2)Minimum damage to equipment as a result of flow of heavy fault currents 3)Improve reliability of power supply

c) Capacitor Voltage Transformer (CVT): A capacitor voltage transformer (CVT) is a transformer used in power systems to step-down extra high voltage signals and provide low voltage signals either for measurement or to operate a protective relay.

d) Isolators with Earth Switches (ES):Isolators are the no load switches and used to isolate the equipment. (Either line equipment, power transformer equipment or power transformer). With the isolators, we are able to see the isolation of the equipment with our naked eye. The line isolators are used to isolate the high voltage from flow through the line into the bus. This isolator prevents the instruments to get damaged. It also allows the only needed voltage and rest is earthed by itself.

e) Current Transformer(C.T.): Current transformer is a current measuring device used to measure the currents in high voltage lines directly by stepping down the currents to measurable values by means of electromagnetic circuit. A Current Transformer (www.muradnagar.infoisinfo.co.in)

f) Potential Transformer(P.T.): Potential transformer or voltage transformer gets used in electrical power system for stepping down the system voltage to a safe value which can be fed to low ratings meters and relays. Commercially available relays and meters used for protection and metering, are designed for low voltage.

g) Circuit Breaker: The circuit breakers are used to break the circuit if any fault occurs in any of the instrument. These circuit breaker breaks for a fault which can damage other instrument in the station. For any unwanted fault over the station we need to break the line current. This is only done automatically by the circuit breaker. These are load switches. It is able to make or break the normal load current as well as the fault currents.

Types of Circuit Breakers used in Plant1)Natural air (called air circuit breakers-ACB) (415v) 2)Vacuum (called vacuum circuit breaker-VCB) 3)SF6 gas (called Sulphur Hexafluoride-SF6 gas CB)

h) Bus: The bus is a line in which the incoming feeders come into and get into the instruments for further step up or step down. The first bus is used for putting the incoming feeders in la single line. There may be double line in the bus so that if any fault occurs in the one the other can still have the current and the supply will not stop.

Fire Pump HouseDefinition: Fire pump house as the name states is responsible for providing water supply to fight the fire in case of a fire hazard or a calamity. The supply of water from this dept. is connected to various fire hydrants located in vicinity of every dept. in the plant. Pumps Present: There are total of 7 pumps present in the fire pump house. There's a large tank that stores about 2000 KL of water at an instant. These seven pumps are responsible for transporting the water from pump house to the hydrants. The 2 Jockey pumps are required when small volume of water is required otherwise there are 3 main pumps present which act as primary pumps to deliver water in case of fire. They run on electricity therefore there are 2 diesel operated pumps that can be operated even during a power outage.

Project Undertaken: MSDS Label Making & EvaluationDuring our second week of training we issued a project by Anshul Aggarwal san regarding MSDS labels & evaluation of chemicals used in Utility department.Definition: A Material Safety Data Sheet (MSDS) is a document that contains information on the potential hazards (health, fire, reactivity and environmental) and how to work safely with the chemical product. It is an essential starting point for the development of a complete health and safety program. It also contains information on the use, storage, handling and emergency procedures all related to the hazards of the material.Problem: MSDS is hard to read. Traditionally the intended readers of MSDSs were occupational hygienists and safety professionals. Now the audience also includes employers, workers, supervisors, nurses, doctors, emergency responders and workers. Solution: To ensure that MSDS users can quickly find the information that they need, the information should be in an easy-to-read format and written in a clear, precise and understandable manner. Therefore, we designed an easy to understand MSDS label using NFPA(National Fire Protection Agency) standard diamond, used graphic images in PPE(personal protective equipment) & created an information column so that even a layman can understand. We also labelled the diamond with alphabets to prevent identification problems in case of a black & white printout.We were also given a list of chemicals in the form of an Excel sheet. These chemicals are used in Utility department. Our task was to correctly evaluate the chart. We corrected any wrong information and added any missing information regarding the chemicals.

Assembly Frame ShopDefinition: An assembly line is manufacturing process in which parts are added as semi finished assembly moves from work station where parts are added in sequence unit assembly is produced.The main assembly line consists of exterior, wiring, interior and chassis which at various points are connected to sub assemblies including door, tires, instrument panel engine and rear axle. The efficient layout with synchronized sub-assembly conveyors are made for more efficient control over human, machine interaction and logistics. Vehicle bodies are here to run on FDS(Friction drive system) conveyor of overhead type making it easier for operator to work on sub-assemblies. The integrated nature of assembly line also results in lower physical fatigue for operators, thereby inc. their efficiency.Flow diagram for A/F shop

Public Announcement SystemDefinition: In case of an emergency or a natural calamity, PA system operator makes announcements use the PA microphone which transmits that signal in every department. Upon hearing this announcement all the employees gather around the designated meeting point in garden area of every department. After that a head count is done to determine the number of employees who are safe and those who are still in danger.

PO (Injection Moulding Shop)Definition: PO shop is an alias for injection moulding shop. Injection moulding is amanufacturingprocess for producing parts by injecting material into a mould. Injection moulding can be performed with a host of materials, including metals,glasses, thermoplasticandthermosettingpolymers. Material for the part is fed into a heated barrel, mixed, and forced into a mould cavity, where it cools and hardens to the configuration of the cavity. Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entirebody panelsofcars.Working: The injection unit takes plastic raw material granules, heats them until molten, and injects them into the mould. Machines have a barrel that contains a screw, the barrel has heater bands around the outside which raises the temperature(200~280), to the correct level to melt the plastic. The rotating screw(50-150 rpm) forces the plastic along the barrel (at about 3500 tonnes pressure). This in turn forces the screw back as the molten material collects at the end of the screw. When the right amount of material for the next shot has accumulated the screw stops rotating. The screw then acts like a plunger moving forward and forcing the molten plastic into themould tool. The clamping end with moving platen takes half of themould tool. This opens and closes the mould and supplies sufficient force to keep the mould closed when molten plastic is injected under pressure.

POPA (Bumper Painting) ShopDefinition: POPA dept. is nothing but an alias for bumper painting shop. Freshly produced bumpers are transferred from plastic injection to the bumper painting shop, there bumpers of different models are painted according to the requirement of assembly frame department. Operation: As we mentioned earlier freshly produced bumpers come from plastic injection shop, these bumpers have information tags on them regarding model number, colour, finish etc. information on them. The bumpers are not metallic in nature and constructed from plastic granules. Therefore, the first coat on the bumper is the primer coat or the undercoat. Priming ensures better adhesionof paint to the surface, increases paint durability, and provides additional protection for the material being painted. The second coat is the base The base coat is applied after the primer coat. This coat contains the visual properties of colour and effects, and is usually the one referred to as the paint. Usually sprayed on top of a coloured basecoat, clear coat is a glossy and transparent coating that forms the final interface with the environment. For this reason, clear coat must be durable enough to resist abrasion and chemically stable enough to withstand UV light. When the painting process is completed the bumper goes through a polishing zone and it's also cured under the ultra violet lights also called the zebra checking point. The completely finished bumpers are then sent to operators for attaching the font grills and headlights( tail lights in case of rear bumper ). The finished part i.e. the front end or rear end is then sent to the assembly frame shop.

Spin CastingDefinition: Casting is a manufacturing process by which a liquid material is usually poured into a mould, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mould to complete the process.Spin casting: Spin casting is a special casting technique which uses centrifugal force to produce hollow casting. Due to the centrifugal force involved no core is required in this process which makes it very convenient and advantageous.Process: Metal (or alloy) to be casted is melted in a furnace by heating it to the required temperature (1200-1500C) and this molten metal is the passed to the holding furnace. A permanent mould is rotated continuously about its axis at high speeds (1000-1500 rpm) as the molten metal is poured. The molten metal is centrifugally thrown towards the inside mould wall, where it solidifies after cooling. The casting is usually a fine-grained casting with a very fine-grained outer diameter, owing to chilling against the mould surface. After the process is complete, we obtain 1 long tube which is passed through shot blast in which the surface impurities are removed by small steel shots bombarded on the surface of the tube. This tube is then passed through a CNC cutting machine which is programmed for cutting is into the desired no. Of cylinder liners (14 in case of petrol and 12 in case of diesel engine).

After the desired length is obtained these liners are finish machined which involves boring and chamfering. The process is concluded with quality inspection which involves inspection for any deformity, defects and dimensional accuracy. The manufactured cylinder liners are then sent to engine assembly for installation.

Press ShopDefinition: Aforming press, commonly shortened topress, is amachine toolthat changes the shape of a work piece by the application of pressure.Presses can be classified on various parameters for example, according to their mechanism:hydraulic,mechanical,pneumatic etc.Operation: There are 2 types of press machines are being used in plant. One is mechanically operated and other is servo motor operated. The output is measured in strokes per minute or SPM. the mechanical press has 9 SPM & servo operated press has 11 SPM. The production of a vehicle begins in the press shop, where sheet metal is integrated into the manufacturing process and the first shapes of the later vehicle are created.

ConclusionThis internship was a great opportunity for us engineering students & we again would like to thank HONDA for providing this to us. As we have mentioned earlier our main purpose coming here was to gain experience, get a feel how a large manufacturing plant operates, what is the code of conduct etc. It's safe to say that our expectations were blown away, coming here we realized how much hard work and their precise management is required to run the plant round the clock. For a layman it must be difficult to comprehend how this plant works but being here we realized it's possible because every employee from each department does his/her designated task efficiently in shortest possible without compromising on quality. We were placed in the Utility department, in simple terms we can say that Utility department is the fuel if this plant is a machine & a HONDA vehicle is finished product. Utility department doesn't aid in production of vehicles directly but supplies the other department that are directly involved in production with the resources that are critically needed for the completion of their task. Our time at HONDA was a great learning experience for us & we hope we can apply some knowledge in our future workplaces.
