ABSTRACT In order to get faster result over a particular period, maximum utilization of is very much required. So if the proper utilization of time will be done then the maximum efficiency will be produced with in the industry. My topic “Time study of ETSA & Rear axle sub assembly and design layout of line no.1 (assembely-1)”at Maruti is very much related with above fact. There are many reasons for wanting to know the amount of time a particular task should take to be completed. It may simply be for reasons of curiosity. But realistically, it is for any of three reasons: (1) to accomplish planning, (2) determine performance and (3) establish costs. In this project I have calculated the total time that the each worker at each station took to complete its task in ETSA(Engine Transmission Sub Assembly of WagonR) and rear axle sub assembly of line no-4 (Eeco & Ritz) and I also design the layout of line no.1(Omni & Ritz).I have calculated time at different station with the help of stop watch and for layout design I visit all the station of line no.1 to find how many workers are engaged there and note all the workers working in different sections of line no.1 and know its category(category such as permanent, T.T, casual, apprentice, repairmen & reliever. After finding various details of 3 sections –trim, chasis and final of line no.1, I designed the layout of line no.1.

ABOUT MARUTI SUZUKI INDIA LIMITED THE START OF A NEW ERA: Maruti Suzuki India Limited (MSIL) was established in Feb 1981 through an Act of Parliament, to meet the growing demand of a personal mode of transport caused by the lack of an efficient public transport system. Suzuki Motor Company was chosen from seven prospective partners worldwide. This was done not only due to their undisputed leadership in small cars but also due to their commitment to actively bring to MSIL contemporary technology and Japanese management practices (which had catapulted Japan over USA to the status of the top auto manufacturing country in the world). A license and a Joint Venture agreement were signed between Govt. of India and Suzuki Motor Company (now Suzuki Motor Corporation of Japan) in Oct 1982. The objectives of MSIL then were: 1.

Modernization of the Indian Automobile Industry.

2.

Production of fuel-efficient vehicles to conserve scarce resources.

3. Production of large number of motor vehicles, which was necessary for economic growth. THE REVOLUTION: Maruti created history by going into production in a record time of 13 months. On 14 December 1983, the then Prime Minister of India, Mrs. Indira Gandhi, handed over the keys of the first car to Mr. Harpal Singh of Delhi. Volume targets were routinely exceeded, and in March 1994, Maruti became the first Indian company to produce over one million vehicles. Maruti is one of the most successful automobile joint ventures, and has made profits every year since inception till 2000-01. In 2000-01, although Maruti generated operating profits on an income of Rs. 92.5 billion, high depreciation on new model launches resulted in a book loss. Maruti revolutionized the way Indians looked at cars. "No other car company so completely dominates its home market" - (The Economist). Despite there being more than 10 companies now in the passenger car market, Maruti holds about 54.5% of the total market share. MSIL is also the first and only car company in the world to lead its home market in terms of both market share and in the JD Power Customer Satisfaction study.

TRANSFER OF TECHNOLOGY: Every 26 seconds a vehicle rolls out of the Maruti plant. It is therefore imperative that the transfer of contemporary technology from its partner SUZUKI is a smooth process. Great stresses are laid on training and motivating the people who man and maintain the equipment, since the best equipment alone can’t guarantee high quality and productivity. From the beginning it was a conscious decision to send people to SUZUKI Motor Corporation for on the job training for line technician supervisors and engineers. These help them to imbibe the culture in a way that merely transferring technology through documents can never replicate. At present 20% of its workforce has been trained under this program.

ETHOS OF MARUTI:

• • • • •

Employees are Maruti’s greatest strength and asset. It is this underlying philosophy that has moulded its workforce into a team with common goals and objectives. The employeemanagement relationship is therefore characterized by: • Customer obsession • Fast, flexible and first mover • Innovation and creativity • Networking and partnership Openness and learning Participative management Team work and kaizen Communication and information sharing Open office culture for easy accessibility To implement this philosophy, Maruti has taken several measures like a flat organizational structure. There are only three levels of responsibilities ranging from the Board of Directors, Division to Head of departments. Other visible features of this philosophy are an open office, common uniforms at all levels, and a common canteen to all. The structure ensures better communication and speedy decision making process. It also creates an environment that builds trust, transparency and a sense of belonging amongst employees.

GITM GURGAON Page 8

SHAREHOLDING: Maruti Suzuki India Limited was set up as a deemed public limited company in 1981 by an Act of Parliament. MSIL was classified in the Public Sector as long as the equity of Government of India remained over 51%. A License and Joint Venture Agreement was signed in 1982, with Suzuki Motor Corporation (SMC) acquiring 26% of the equity. SMC increased its equity to 40% in 1989. In 1992, Maruti ceased to be a government company, as SMC's equity holding went up to 50%. In 2002, SMC's share went up to 54.2%, making MSIL a subsidiary of SMC. The Govt. of India held 46.6%, and employees trust holds the balance 0.2%. As of Sept 2006, Suzuki holds 54.21% shares, Govt. of India hold 10.27%, rest of the shares are distributed between the public, Insurance companies, FIIs, Mutual funds etc.

VISION OF MARUTI: • To be The leader in the Indian automobile industry • Creating customer delight and shareholder’s wealth • Be A pride of India

MARUTI SUZUKI INDIA CULTURE Building a distinctive organizational culture is one of the most challenging tasks faced by any company. By organizational culture, is meant an organizational philosophy, which guides the actions and behavioral pattern of the members. It also defines implicitly how the external agents perceive the organization. Hence the necessity of a work culture which, while appealing to those within, also satisfies the expectations of those outside the organizational environment. There is no use for a work ethic that creates highly efficient pseudo-robots out of the employees. Such an approach might look like giving dividend in the short term but will definitely lead to stagnation and frustration in the long term. A harmony between the work culture and organizational objectives is hence very essential. It is the duty of every employee to work towards sustaining the “MARUTI CULTURE”, which is built over the years.

COMMUNICATION CHANNELS As a part of open culture, all managers strive to facilitate both top-down as well as bottom-up communications. At all levels, throughout the company employees can communicate on any business, organizational or personal concern, without having to cross many channels. The organizational structure has deliberately been kept very flat to facilitate communication.


ORGANISATIONAL STRUCTURE AT MSIL MSIL is a functional organization. The Company is divided into different divisions according to the various functional areas. A Divisional Manager heads each Division. Divisions are further divided into Departments, which are headed by Department Managers who report to the respective divisional managers. Designations in the Company are based on the functional responsibility in terms of the Company's philosophy of de linking designations and functional responsibility from the salary levels.

The total operations of the Company are divided into Divisions like Marketing & Sales, Spares, Engineering, Q.A. & Services, Production, Production Engineering, Materials, Information Services, Finance, Personnel & Administration, etc. Each Division is further divided into Departments. For example: In Marketing & Sales Division, the departments are Exports, Marketing, Sales Planning, Sales & Dispatch, RO-East, - West, - South, - North-I, North-II & MSS-N. In Information Services Division, the departments are Marketing & Sales Information, Production Management Information, Materials Management information & Resource Management Information. Maruti Suzuki india Limited has a total of 3354 employees (not including trainees or Japanese experts).


SYSTEM OF DESIGNATION There will be a dual set of designations. Internally, only the designations linked to functional responsibility will be used. For external dealings a different set of designations may be followed. The following system of designations would be practiced without any exception within the Company. For the purposes of defining explicit responsibility centers, The Company has been divided into three layers of management. 

Division

 Department  Section An official of the Company, who will be designated as Divisional Manager, Department Manager, Section Manager respectively would head each of these responsibility centers. Remaining employees of the Company will have no specific designation and would simply use the name of the Division/Department/Section to which they belong, to identify their location in the Company. The MD would make appointment to positions of Divisional Managers and Department Managers only. The Divisional Managers would appoint section Managers.

HOW IS A CAR MADE The making of a car starts from the press shop, where the raw material is obtained in the form of cold- rolled sheets. From the press shop, the parts are send to the weld shop, where they are welded to make the frame of the car. From the weld shop, these frames are transferred via conveyors to the paint shop, where these are coated and glazed. From the paint shop, these are send to the assembly shop, where through a conveyor system, various parts are fitted at various canopies or stations. The machine shop and the Engine assembly shops are located close to the respective assemblies, and the car engine and other transmission parts are also fitted in the assembly shop itself. Then, the V.I deptt. conducts various tests to ensure that no defects remain before the car is dispatched via trucks to various parts of the country.


The flow chart for a typical car body weld line looks as follows:


The basic layout of a paint shop is as follows:

From weld shop


The features of an assembly shop is shown as follows : Trim line: The car body moves over the conveyor on mounts, as shown below:

Chassis Line: Here, the car is loaded on overhead jigs as shown below:

Final Line: Here, as both the engine and wheels have been fitted, the car once again moves over the conveyor belt.


DIFFERENT SHOPS IN MARUTI SUZUKI INDIA LIMITED 1. PRESS SHOP The press shop can be regarded as the starting point of the car manufacturing process. Centrally located between weld 1, weld 2 and weld 3 supplies components to all the three plants. The press shop has a batch production system whereas the plants have a line production system. The press shop maintains an inventory of at least two days. The weld shop as per the requirements picks the finished body parts from the press shop. These may be divided as A, B and C. ‘A’ components are large outer components as for example roof, door panels etc. These components are manufactured in the press shop at Maruti due to design secrecy and huge investment requirements. ‘B’ and ‘C’ components are manufactured by joint ventures or bought from vendors. The press shop can be explained under following headings: (a) Raw material (b) Blanking line (c) Stamping line (a) Raw material: The raw material is in the form of cold rolled steel coils. It is specified in terms of steel grade and width of coil required. The coils weigh about 15000 kg. (b) Blanking line: There are two blanking lines; ROSL (Rotary Oscillatory shear line) for rectangular shapes and the others employing die cutting for irregular shapes. (c) Stamping line: there are six presses of capacity varying from 1500 Ton to 4000 Ton, out of which five are transfer presses and one is semi-automatic press. The die can be changed to obtain different body components. GITM GURGAON Page 24

2. WELD SHOP The body panels produced in the press shop and the other small components are joined here to give the “white body” or “shell”. In a typical car body 1400 different components are welded together. The weld shops have the following facilities.  Welding jigs  Spot welding guns  Kawasaki welding robots  Hemming machines  Punching machines PROCESS OUTLINE: The shop has different lines for different models, each of, which is further divided into three parts: UNDER BODY: Here different underbody panels are welded together. These comprise of rear underbody, central underbody, front engine room panel. These underbodies are put on the conveyor and welded together to give the underbody. MAIN BODY: As the body moves on, the conveyor roof and side body panels (prepared on the sub lines) are welded to it to give the main body. The chassis number is punched on the cowl top and it is welded to the front engine room panel. WHITE BODY: The doors, hood and back door are attached on the main body with the help of bolts and screws to make it a “white body”. The body is checked for dent, burr and spatter and these defects are repaired. After inspection and repairs the body is called WBOK. It is sent to the paint shop thereafter.


3. PAINT SHOP In the paint shop following processes are carried out: There are five plants/units that provide a uniform painting over the white body coming from the weld shop. In paint shop all the models are painted on the same line. The five units are: (a) Pre-treatment (PT): The body is thoroughly washed to remove the dirt and oil scales. Then the body is treated with ZnPO4 (phosphating) to prevent corroding of the body. (b) ED coat: This is done by electric deposition method, at 240V-dc supply. After applying the ED coat the body is baked in oven. (c) Sol-sealer and under coat: Here the left in the body (due to welding) are filled with sol-sealer to provide waterproofing. Under coat is done on the surface above wheels to prevent damage of body in that portion. (d) Intermediate coat: This is done by spray-painting method using 10 Kawasaki Robots. After applying the coat, the body is dried in the oven. Painting done is basically an intermediate coating to provide base for the final coat. (e) Topcoat: This is done by spray-painting method using 20 Kawasaki Robots. For metallic coating, double coats are applied and aluminum flakes are provided to shine the metallic paints. After inspection and touch up, the PBOK, i.e. the paint body ok is sent to the assembly shop.


MACHINE SHOP The machine shop is the source of all major components for the Engine Assy. Shop. The unmachined crankshaft and camshaft forgings, transmission case, cylinder head and cylinder block castings are brought in as raw material from vendors. The cylinder head and transmission case are aluminum castings while crankshaft and camshaft are steel forgings. It has the following lines  Transmission Case Line  Cylinder Head Line  Cylinder Block Line  Crankshaft Line  Camshaft Line

ENGINE ASSEMBLY Engine assembly 3 is currently used to assemble the 1061cc engine for WagonR, F8D engine (5-speed transmission, 796cc MPFI) for Car800 and Alto. Engine assembly is divided into 3 main Sub-Assemblies, one Main Line and a Firing Test. The sub assemblies are:  Cylinder Block Line  Cylinder Head Line  Transmission Line The cylinder block, cylinder head, transmission case, camshaft and crankshaft are received here from the machine shop.


ASSEMBLY SHOP -I There are 3 assembly shops in MSIL which produce on an average 1750 cars daily. The assembly shop receives PB-OK i.e. paint body OK from the paint shop. Here the body is loaded on an over head conveyor. As the conveyor moves the body, fitments are made at various stations. Assembly I mainly produces MARUTI 800 (Domestic & Export Mainly), ZEN ESTILO (Domestic& Export), OMNI(Passenger & Cargo), EECO,RITZ & WAGON R(new model). The Whole process of assembling undergoes through different number of stations. There are about 375 employees in two shifts. The Asssembly shop can be further subdivided as following  Trim  Chassis  Final TRIM LINE Trim can be further subdivided as following: Trim 1 This is the beginning of the assembly line conveyor. Here amongst the first tasks done is attaching the hydraulic supporters for the boot. The assembly line check sheet is put inside the body. Door is removed here and sent to final line .The various fitments made here are door/floor grommets, electric wiring, and door trims parking brake cable, inner and outer door openers, model stickers and emblems, roof silencer and cabin lamp. Steering gear case is put inside to be fixed later.

Trim 2 GITM GURGAON Page 28

It starts with Rear combination light fitment. Other operations done here are vacuum booster/ brake master cylinder fitment, seat belts, fuse box, wiper sprayer and motor, accelerator, clutch, brake pedals, door glasses and a/c panel fitment. Trim 2 ends with the fitment of the instrument panel, which is received from an instrument panel subassembly. This sub assembly involves the fitting of the speedometer console, ashtray and stereo system. . Trim 3 The fittings done here are rear inside cover for boot, back door glass and windshield, quarter glasses and connecting pipe between fuel lid and fuel tank. Steering gear is mounted. For cemendine application on the windshield, Motoman robots are employed. Here a process check is done CHASSIS The chassis receives a trim up body. Here underbody fitments are made, hence body is loaded on overhead jigs. Chassis is subdivided as following: Chassis 1 Various fitments made here are rear shock absorbers, brake pipes, front coil spring with knuckle, steering wheel, tie rods, rear suspension, fuel pipes, fuel tank and rear brake drum. There is a knuckle sub assembly that feeds the line with knuckles for the front suspension system. Process check is done at the end of Chassis 1. Chassis 2 The fitments made here the exhaust system (silencer and catalytic converter), engine cum transmission case assembly, gearshift rod, front and rear bumpers, stabilizer bars and tyres. The tie rod and drive shafts are connected to the knuckle to complete the front suspension system and ID plate fixation. A process check is done at the end of chassis 2. GITM GURGAON Page 29

FINAL Since all the fitments have been made, the body is referred as vehicle from now onwards. The vehicle is loaded on the final conveyor. Final area is further subdivided as: Final 1 The fitments made here are Spare wheel cover, scuff, seats, roof trim and carpet, boot carpet, battery and air cleaner. Clutch cable and parking brake connections are made. Brakes are evacuated and brake oil is filled. Coolant is also filled. Final 2 Five liters of petrol is filled in the vehicle. A/C vaccum and charging is also done here, the refrigerant used here is R134a (400 gm +- 50).Door Assembly is also done here. Final 3 There is a process check at the end of this line. The vehicle is said to be AB-OK now. It is handed over to the vehicle inspection department.


VEHICLE INSPECTION - I The VEHICLE INSPECTION II having the following stations :  Toe-in test  Slip tester  Head lamp test  Appearance test  Drum test  Brake test  Engine room and Pit inspection  Shower test  Road test  Final check General Procedure In VI a vehicle is checked at checkpoints in the above mentioned order. At each checkpoint different parameters are checked. Each vehicle is issued a check-sheet in which the operator at the check points marks down the defects if any, otherwise he marks an OK stamp. After the road test if the vehicle has no defects marked in the check sheet it goes to the final check conveyor belt where it is again checked for overall appearance. If a vehicle has any defect then it is sent to the following repair areas depending on the type of defect:  Assembly repair  Weld repair  Paint repair  Engine Assembly repair


After repairs the vehicle is then sent to the final check conveyor where the repair work is checked and if satisfactory then the vehicle is given final clearance. Toe-In Test This is the first inspection point for a vehicle once it comes off the assembly line conveyor. Before the vehicle is accepted for this test it is checked for external damages, feel of the brakes and floor carpet. The objectives of doing the toe-in test are as follows:  Minimum tyre wear  Steering position OK  Minimum side slip Toe-In refers to the alignment of the wheels. It is not possible to have a wheel alignment such that the wheels are perfectly straight (ideally this leads to minimum tyre wear). The wheels are either pointing slightly inwards (toe-in) or outwards (toe-out). Also when a car is in motion then the wheels tend to align outwards so vehicles are generally set with a toe-in condition. Statistical analysis and experiments has given a value of toe-in 2 and toe-out 1 for front wheels in Car800, WagonR and Baleno. Baleno has rear wheel allowance of toe-in 3.5 and toe-out 0.5. Another point checked here is the steering position. Correct steering position refers to that setting of the steering wheel that would allow the car to move in a straight line and which is the natural position of the wheel i.e. the driver isn’t holding the steering wheel. Figure no. 5 shows the toe-in tester machine.


SLIP TESTER This machine checks vehicle slipping after the toe in adjustment. The machine is calibrated for 2 unit toe-in and 1 unit toe-out. If the vehicle slipping falls in between the calibration limits, the vehicle is OK in slipping otherwise NOT OK. HEAD LAMP TESTER Often the car driver faces the problem, the headlight beam adjustment. Because of the maladjustment the light beam falls on unwanted objects. At the headlamp tester, a yellow cross represents the position of the headlamp whereas the point where it should ideally be is shown as green rectangle. The operator manning the test tries to get the yellow cross inside the green rectangle by adjusting screws for horizontal and vertical alignment of the lamp. Apart from checking the headlamp, turning radius and other things are also checked at this checkpoint. Appearance Test This test involves evaluating a vehicle on a large number of parameters ranging mainly from external appearance of the vehicle to the internal trim fittings to checking for coolant level and braking fluid level. The vehicle is loaded on a conveyor. The vehicle is visually inspected for weld, paint and assembly defects and the same are marked on the diagrammatic representation given on the checksheet. The appearance check points are I.D plate, emblems, bumper, doors, fuel lid, front hood, routing and clamping, seats, interiors, seat belts, weather strips, tyres and glasses. Various paint defects are paint peel off, scratches, paint miss, overflow, orange peel, shade mismatch, pin holes sealer application and sanding marks. Various weld defects are level difference, dents, door gap and fouling. The vehicle is driven in all the gears and the various parameters checked are as follows: GITM GURGAON Page 33

 Steering wheel : position/vibration  Clutch : free play 20-30 mm/noise/engagement/disengagement  Accelerator Pedal: free play 2-7 mm/operation  Gear shifting: hard/noise/slippage  Speedometer: needle vibration/error/reading at 40 km/h  Horn: volume/tone  Wiper/washer (front/rear): auto stop position/wiping/spraying position  Warning

Brake Tester The front and rear brake forces are measured here. Here the brake pedal is checked for hardness, sponginess, play and noise. Parking brake force is also checked here. The vehicle is moved onto the drums, vehicle brakes are employed and the corresponding resistance force is measured with the help of computerized machine. The measured force is displayed on the screen and must lie between the values prescribed by the company. GITM GURGAON Page 34

Engine Room Here the engine is inspected for various kinds of defects such as tappet noise, clutch lever play (Car800), exhaust emissions as per the standards laid down, idling rpm with and without A/C switched on. In case of MPI cars, a DLC (Data Link Connector) cable is used to detect the working of Electronic Control Module and various sensors. The DLC cable is connected to a computer which shows not ok if there is any malfunctioning in the engine. The defects are noted on the checksheet to be repaired in assembly or engine assembly. Pit Inspection The underbody of the vehicle is checked for: Brake fluid/coolant/fuel/engine oil leakage Red and yellow paint on nuts, bolts and fuel and brake pipes (the paint indicates that the nuts and bolts have been properly assembled and checked for torque)Muffler mounting bolt Rear suspension coil or leaf spring Shower Tester The vehicle is moved on the shower tester conveyor belt where it passes through a series of shower jets aligned at different angles and locations. While passing through, the vehicle is sealed i.e. all window glasses are rolled up and doors closed. When the vehicle exits from other side of the shower tester an inspector checks the cabin for water seepage. If water is found, then the particular leak defect is repaired in the shower repair section following which the vehicle is sent for the road test.

Road Test


Road test of a vehicle consists of a track on which the vehicle is run at predetermined speed. The track is designed so as to check the various aspects of the vehicle such as braking, acceleration, handling, performance etc. Distance traveled after application of brakes, reverse braking and Steering positioning is also checked. After driving the car at a fast speed it is made to take a U-turn to try and find for any loose part in the panel. Other parameters checked in the road test are:  Steering stability: position/play/vibration  Clutch/accelerator pedal: play/noise  Brake: noise/sponginess/brake pulling  Rear view mirror: blurred image/distortion  Gear shifting: gear slip/engagement/hard disengagement/noise  Defogger: functioning  Speedometer: needle vibration  Abnormal noise of any kind from panels, doors, wheels , engine, hood etc is noted down Final Check This is the last of the vehicle inspection checks. After the vehicle has gone through the other tests and if there are no repairs to be done then it is sent to final check. Here the overall appearance of the vehicle is checked again. Scratches, dents, cleanliness and Cemedine(windscreen sealer) leftovers are checked for. Also secondary defects i.e. defects that may creep in while repairing the primary defects are also checked for. Inspection stamps for all the previous check stations are checked to see that there is no inspection miss. Finally the chassis and engine number on the I.D. plate are verified and the Final Check OK ( FCOK) sticker is put on the car and it is sent to the final check parking area. FC OK’ed vehicles are later picked by the Sales and Dispatch drivers.


NEED FOR THE PROJECT

The need of the project is to increase the productivity of the workers both in terms of quality and quantity. This can be achieved by doing the time study of the various working stations of line. The main purpose of implementing time study in ETSA & Rear Axle Sub Assembly and layout design is to-

 Identify and Eliminate hidden waste of time- Hidden waste refers to those waste which are not visible during the process but still exist.

 To calculate standard time of each process- Standard time of each action performed by the worker is calculated by using MOST, thus standard time of each process can be found.

 Line balancing- The goal in balancing an assembly line is to assign tasks to stations such that equal amount of work is performed at each station.

 Man power reduction- To optimize the Line by calculating the required Man power & removing the extra workers from the line.


Introduction to Time Study In business efficiency studies, Time Study (an Industrial Engineering term) is the time required for a person to complete a task or operation at a defined rate of working. It includes appropriate allowances to allow the person to recover from fatigue and, where necessary, an additional allowance to cover contingent elements which may occur but have not been observed. The Standard Time is the product of three factors: 1. Observed Time - The time required to complete the task. 1. Rating Factor - The pace the person is working at. 90% is working slower than normal, 110% is working faster than normal, 100% is normal. This factor is calculated by an Industrial Engineer trained to observe and determine the rating. 1. PFD Allowance - Personal, Fatigue, and Delay Allowances. These include factors such as: Are the workers standing all day? Are they working in a cold environment? Do they have to wear safety equipment?

Method to Calculate Time: In this project I have calculated time at different stations by using stop watch. Before calculating the time at each, first we have saw that how many operator at each station has and what is their method of doing the work. If we analyze all the relevant details of station and accurately knew the amount of component that each operator fit in the object then only accurate time is measured with the stop watch.

Rear Axle Sub Assembly Line No.4 In rear axle sub assembly of line no.4 rear axle of Eeco & Ritz are made. In this section there are 3 stations in which different operation performed by each operator. In this various components attached to the axle frame. The components such as brake sub assembly, drum head, trailing arm, parking cable, break pipe, E rings, clamps, spindle rear, sticker, oil filling in Eeco, hose pipe, plug, bump stopper, helical springs etc. In this section there are two stations on conveyor belt and one station for engine mounting. Stations of Rear Axle Sub Assembly  Station no.1

 Station no.2R  Station no.2L  Station no.3

DESCRIPTION OF STATIONS AT REAR AXLE SUB ASSEMBLY:

STATION NO.1:


In this station the axle of Eeco & Ritz first transfer from trolleys to the station no1 with the help of crane and then component such as brake sub assembly, hose pipe, oil filing etc. done on axle frame. In this station only one worker is engaged.

STATION NO.2: In this station 2 workers are engaged on left and right side. At station no.2 (R&L) the component such as trailing arms, brake pipes, hose pipes, clamps, parking cable and drum head attach on the axle body.

STATION NO.3: In this station the axle is moved from conveyer belt to lift and from lift it is attached to car body with the help of bolts and lateral rod, helical springs also attach at the same time.

Time Calculation: Time at each station is calculated 3 times with the stop watch, so that standard time can be obtained. Standard time of both cars of line no.4 Eeco & Ritz at each station is shown below in the table.

Line Layout of Line no.5 INTRODUCTION: A line layout study is an engineering study used to analyze different physical configurations for an industrial plant.

Definition: Definition of Line Lay out Line Layout is the physical arrangement of equipment, facilities & man power within a line. The Line Layout can be indicated on a floor plan showing the distances between different features of the line. Optimizing the Layout of a line can improve productivity, safety and quality of Products. Unnecessary efforts of materials handling can be avoided when the Line Layout is optimized. This is valid for: - Distances Material has to move - Distances Equipment has to move - Distances Operators have to move - Types of Handling Equipments needed - Energy required to move items against resistance (i.e. gravity)


Line Lay out of line no.5(WAGON-R) Line no.5 mainly contains three most important sections. The sections are:  Trim  Chassis  Final Trim: Trim of line no.5 has 23 stations on its right side and 23 stations on its left side. In trim sections 34 workers are engaged at its different stations and all are of different categories. The categories such as casual, permanent, T.T, apprentice, reliver and repairmen. The category of each worker at each station is shown in table 3.

Chassis: Chassis of line no.5 has 14 stations on its right side and 14 stations on its left side. In chassis sections 26 workers are engaged at its different stations and all are of different categories. The categories such as casual, permanent, T.T, apprentice, reliver and repairmen. The category of each worker at each station is shown in table 4. Final: Final of line no.5 has 29 stations on its right side and 29 stations on its left side. In final sections 47 workers are engaged at its different stations and all are of different categories. The categories such as casual, permanent, T.T, apprentice, reliver and repairmen. The category of each worker at each station is shown in table 5. GITM GURGAON Page 44

CONCLUSION The 6 weeks Industrial Training is indeed the most important part of our curriculum at the Mechanical Engineering Department of GITM GURGAON. It provides me an opportunity to gain experience on the practical application our technical knowledge. I have done my industrial training in the ASSEMBLY SHOP-1 of MARUTI SUZUKI INDIA LIMITED. In my training I have leaned 2 topics TIME STUDY TECHNIQUE AND LINE LAY OUT DESIGN. Time Study is a very useful tool which can be employed in manufacturing companies like Maruti which have to constantly cater to ever increasing demand from the market with very small lead times. The overall experience that I have gained at Maruti helped me a lot in my future. In the end I would like to thank my Mentor at Maruti and all staff members of assembly shop -1 who have encouraged and inspired me to achieve higher goals.
