1.7 DEPARTMENTS
(i) Engineering Department
(ii) Production Department
(iii) Welding department
(iv) Quality section
(i) ENGINEERING DEPARTMENT
1. Engineering department deals with development of the fore coming parts of
Maruti.
2. Generally, majority of the parts are from MUL, Ggn. Parts are prepared and
there trial is taken. This department also deals with costing of sheet metal
parts, in which quotation are prepared in order to submit to the customers and
vendors.
6
(ii) Production Department
In production department metal sheets are given desired shapes through stamping
process.Stamping press is used to produce the stamping operation.
What is a stamping press ?
A stamping press is a machine that houses the stamping tools (tooling) and carries them
around according to the kinematics indicated by the users (process set-up).
The knowledge of the press used for a stamping operation provides us with useful clues
regarding:
Values and distribution of restraining forces
Tool deformation caused by stamping forces
Contact and/or gap between tools and blank
However, we should recall that,at the moment when the die design is carried out, the press is
usually not yet known, so that its characteristics are rather a factor of noise than a useful
information.Therefore,it bwill be important to have a design that is robust with respect to the
press type.

GLOSSARY:
Design surface Part as designed to fit in the car (after trimming)
Blankholder Surfaces that hold the blank before the forming
surface operation, including the restraining
Production Junction between the two former surfaces,
surface/run-offs protecting the design surface and controlling
material flow
Dieface Run-offs + blankholder
(iii) WELDING DPARTMENT
Resistance Welding is a welding process, in which work pieces are welded due to a
combination of a pressure applied to them and a localized heat generated by a high electric
current flowing through the contact area of the weld.
(a) Spot Welding (RSW)
• Spot Welding is a Resistance Welding (RW) process, in which two or more
overlapped metal sheets are joined by spot welds.
The method uses pointed copper electrodes providing passage of electric current. The
electrodes also transmitt pressure required for formation of strong weld.
Diameter of the weld spot is in the range 1/8‖ - 1/2‖ (3 - 12 mm).
Spot welding is widely used in automotive industry for joining vehicle body parts.
9
Fig 1.2: Spot Welding
(b) Resistance Butt Welding
• Resistance Butt Welding is a Resistance Welding (RW) process, in which ends of
wires or rods are held under a pressure and heated by an electric current passing
through the contact area and producing a weld.
Fig 1.3: Butt Welding
10
Butt welding is used for welding small parts. The process is highly productive and clean. In
contrast to Flash Welding, Butt Welding provides joining with no loss of the welded
materials.
(iv) QUALITY CONTROL SECTION
As the name suggests this section houses all sorts of tools and measuring instruments like
vernier calipers, vernier height gauge, slip gauges, surface plates, radius gauges,
inside/outside micrometers, depth gauges and hardness testing machines, torque wrench
testing machine etc. for checking the components purchased from the vendors from outside
the firm before being stored into the store lying adjacent to this section.
This section monitors whether the components supplied by the allied vendor party covers the
quality specifications of the company or not and according takes corrective action as and
when required. It also keeps a track record of the stock of components inside the store.
Being an ISO certified company; the firm is deeply concerned with managing of quality of
the purchased components which ultimately affect the quality of its final product.
The Quality Policy of the company can be quoted as:
Producing world class tractors in quality and reliability
Total customer satisfaction through services
Creating a culture among all employed toward total quality concepts
Constant up gradation of technology and human excellence

has signed MOU’s with several international firms to match up with the latest trends in the
automobile industry, the fastest growing industry of its kind in the current scenario.
Quality improving steps followed by caparo
1. 5S
2. Kaizen
3. 3R
4. 3M
11
1. 5S:-
5S is the name of a workplace organization methodology that uses a list of five
Japanese words which are seiri, seiton, seiso, seiketsu and shitsuke
English meaning of 5S
I. Sorting (Seiri):
Eliminate all unnecessary tools, parts, and instructions. Go through all tools,
materials, and so forth in the plant and work area. Keep only essential items and
eliminate what is not required, prioritizing things per requirements and keeping them
in easily-accessible places. Everything else is stored or discarded.
II. Straightening or setting in order / stabilize (Seiton)
There should be a place for everything and everything should be in its place. The
place for each item should be clearly labeled or demarcated. Items should be
arranged in a manner that promotes efficient work flow, with equipment used most
often being the most easily accessible. Workers should not have to bend repetitively
to access materials. Each tool, part, supply, or piece of equipment should be kept
close to where it will be used – in other words, straightening the flow path. Seiton is
one of the features that distinguishes 5S from "standardized cleanup". This phase can
also be referred to as Simplifying[1]
.
III. Sweeping or shining or cleanliness / systematic cleaning (Seiso)
Clean the workspace and all equipment, and keep it clean, tidy and organized. At the
end of each shift, clean the work area and be sure everything is restored to its place.
This makes it easy to know what goes where and ensures that everything is where it
belongs. Spills, leaks, and other messes also then become a visual signal for
equipment or process steps that need attention. A key point is that maintaining
cleanliness should be part of the daily work – not an occasional activity initiated
when things get too messy.
12
IV. Standardizing (Seiketsu)
Work practices should be consistent and standardized. All work stations for a
particular job should be identical. All employees doing the same job should be able
to work in any station with the same tools that are in the same location in every
station. Everyone should know exactly what his or her responsibilities are for
adhering to the first 3 S's.
V. Sustaining the discipline or self-discipline (Shitsuke)
Maintain and review standards. Once the previous 4 S's have been established, they
become the new way to operate. Maintain focus on this new way and do not allow a
gradual decline back to the old ways. While thinking about the new way, also be
thinking about yet better ways. When an issue arises such as a suggested
improvement, a new way of working, a new tool or a new output requirement,
review the first 4 S's and make changes as appropriate.
2. Kaizen:-
Masaaki Imai defined Kaizen as ―a means of continuing improvement in personal
life, home life, social life, and working life. At the workplace, Kaizen means
continuing improvement involving everyone—managers and workers alike. The
Kaizen business strategy involves everyone in an organization working together to
make improvements without large capital investments.‖
Mark R. Hamel has a slightly different definition: ―Kaizen is much more than an
event; it is a philosophy, mindset and, for breakthrough performance, a most critical
vehicle to achieve strategic imperatives and execute value stream/process
improvement plans.‖
The five main elements of kaizen
Teamwork
Personal discipline
Improved morale
Quality circles
13
Suggestions for improvement
Kaizen is a daily process, the purpose of which goes beyond simple productivity
improvement. It is also a process that, when done correctly, humanizes the
workplace, eliminates overly hard work ("muri"), and teaches people how to perform
experiments on their work using the scientific method and how to learn to spot and
eliminate waste in business processes. In all, the process suggests a humanized
approach to workers and to increasing productivity.
3. 3R:-
Reduce, Reuse, Recycle, a hierarchy of waste management strategies to
minimize waste
4. 3M:-
i. Muda
ii. Mura
iii. Muri
"muda" meaning activity that is wasteful and doesn’t add value.
"mura", meaning "unnevenness"
"muri" meaning "overburdening".

CHAPTER-2
MANUFACTURING OF PARTS
For the manufacturing of the parts first of all the Overview Of The plant is given.
Different operations are performed during the manufacturing of the different parts.
The operations performed during the manufacturing of different parts the following
processes are involved
(1) Press Shop
(2) Welding Shop
(3) Quality Section
2.1 Press Shop:
During the press shop firstly the sheet of Aluminum passes through the different
presses and performed different operations on it. The different presses & different
operations which are performed on the sheet are:
The different kind of presses used in the press shop is:
Type Of Press No. Of.
(1) 800 Tones 2
(2) 400 Tones 3
Table 2.1
The various operations are performed on the sheet during the press shop are
(1) Drawing
(2) Trimming
(3) Restrike
(4) Piercing/ Punching
During the drawing the sheet can be passed through the press of 800 Tones & the
specific shape of the given part provided to the sheet and during trimming the extra
part of the sheet which is not in work can be trim by the press and the extra part can
be thrown into the scrap. During the process of restriking the die can be strike on the
part again so that it can acquire the exact shape of the part & during the process of
15
punching the different holes can be drawn on the part according to the shape. Press
contains different parts such as:
(1) Cushion Bed
(2) Lower Die
(3) Upper Die
The inner parts of a press which help to support the die are:
(1) Damping Unit
(2) Air Cylinder
(3) Lubrication System
The parts are shifted from one press to another by the loader & unloader.
The transfer belt is used to transfer the part from first press to another.
The different parts of press are:

Transfer Belt:
Fig 2.9: Transfer Belt
2.2 Welding Section :
Spot welding can be done on the parts for the joining of different small parts on the main
part. For example studs are attached to the different parts with the help of spot welding. Spot
welding mainly of two types
(i) Integrated Transformer Gun
(ii) Non-Integrated Transfer Gun
These are the two methods mainly used for the spot welding.
21
Integrated transformer gun means a gun which is used for the spot welding contains the
transformer inside the gun. There is no outside transformer placed for the working of the
gun.
On the other hand Non Integrated Transformer gun can be used for the spot welding of
the parts contain a transformer side from the gun.
(i) Integrated Transformer Gun :
Fig 2.10: I.T. Gun
(ii) Non Integrated Transformer Gun :
Fig 2.11: Non I.T. Gun
22
These are the two guns which are used for the welding purpose of the parts manufactured.
2.3 Quality Section:
In the quality section the part manufactured can be checked out
completely. In quality section these things can be checked out in the
part:
(i) Overlapping
(ii) Wrinkle
(iii) Deformation
(iv) Crack
(v) Dent
(vi) Material Strength
These are different facts that can be checked out in quality section which
are necessary to be checked out for the strength and accuracy of the part.
o Manufactured Parts:
Dash Waganor
Dash Versa
Wheel Housing
Chessy
Quarter Inner Lower
Frame Floor
Door Hinge
2.4 Manufacturing Process:
For the manufacturing of the above discussed parts a part is to be followed
by the different operations. Firstly, a part is to be moved from the press shop
where the drawing, trimming, restrike & piercing/punching can be & the
23
shape can be provided to the sheet of the given specific die & then it can be
send to the welding section where the spot welding of the manufactured part
can be done & different studs, nut & bolt can be attached to the part
according to the specification of the part.
`
Manufacturing Process In Press Shop:
In press shop first of all a sheet of aluminum can be taken then it can be
placed in the different dies where different operations can be done on it.
DRAWING: Firstly, the process of draw can be done where the given specific
shape can be applied on the sheet by placing it on the die of that specific shape. The
die can be placed on M.B. in which cushion pins can be put according to the shape
these cushion pins pull up the die & a upper die is attached to upper M.B. with the
help of studs. For the manufacturing of part first of all power is put on and then
pressure is applied to upper die by the air cylinder situated at the top of press and
with the pressure the upper die moves towards down and hit on the lower die. When
the upper die strikes on the lower die the sheet present on the lower die attain the
shape of the die. The lower die does not move towards down because of cushion pin
which support the die. The cushion plays an important role during the manufacturing
of the parts because it support the die if any cushion is placed in a wrong way inside
the M.B. then it will damage the die so it is necessary to place the cushion pins
inside the M.B. correctly. The M.B. is placed on the cushion bed which helps to
absorb the damps which produced when the upper die strikes on the lower with a
pressure of 800 Tones. During the drawing the specific shape can be applied to the
sheet. According the part the can be loaded on the M.B. and the placed on the
cushion bed and then the process of manufacturing starts. Loader takes the sheet
from the shelf where it can be provided by the workers. The loader picks the sheet
and placed it on the die. Then the operation of draw is started and the shape of the
die can be applied on the sheet. There is a big importance of angle of stroke during
the press operations. The accuracy of the part depends upon the stroke of press,
commonly the stroke is 180*(Degree). Lubrication system also plays an important
role during the operation of press because without lubrication it can’t be easier to
24
drive such kind of heavy press so it is necessary that lubricating pump should work
properly.
Fig 2.12: Drawing Operations
TRIMMING : Trimming is a operation in press shop in which after the process of drawing
the remaining part which is useless on behalf of the structure of part is to cut by this press. In
trimming the upper die contains blade on the edges of it and when it strike on the lower die
where the part with extra useless part is placed is to be trimmed. So trimming is a necessary
operation on behalf of the structure of the part. This press is of 400 Tones and strikes on the
lower die which is placed on the M.B. and supported by the cushion pins which are necessary
to hold the die during the striking operation. If any of the cushion pin put in wrong way
inside the M.B. then it will damage the die & sometimes die will breakdown due the pressure
of the press and cant be able to absorb the vibrations produced by the cushion bed and as a
result the die will damage so it is necessary to placed the cushion pins correctly according to
the drawing of the part. During trimming it is necessary to take care of angle of stroke and the
lubrication system because it is necessary for the accurate working of the press. The press
contains a air cylinder on the top of the press in these cylinder air is to be compressed and it
helps in the stroke of the press so there are so many things which can be checked during the
working of press.
25
Fig 2.12: Trimming Operation
So trimming is a operation in which the remaining portion of the part which is not useful is
to be removed by the cutting operations
RESTRIKING: Restriking is a operation in which after the trimming operation the part is
taken by the unloader and put it on the transfer belt which takes it up to the another press
from where the unloader takes the part and put it on the press where the die of same kind is
already placed and the part is placed on the die and then operation of restrike done again. In
the operation of restrike the upper die is again strike on the part which is placed on the lower
die. The lower die is placed on the M.B. and the operation of restrike can be done because
during the operation of drawing some design can be missed and during the restriking
operation these designs can be made on the part so restriking operation is the important
operation on behalf of the design of the manufacturing of part because the accuracy of the
part depends upon the operation. During this operation the stroke of press can be take care so
that the complete process of the designing of part can be completed with complete accuracy
because the accuracy of the part is necessary because the complete design of the car can be
based on the accuracy of that part. So restriking operation can be done on the part after the
trimming operation so that the complete design can be made on the part. In this process again
the cushion pin plays important role on the die because the cushion pins support the die to
absorb the damps which are produced by the striking of upper die on the lower die and the die
press is of 400 Tones which is used for the restriking operation.
26
The part on which the restriking operation an be done:
Fig 2.13: Restriking Operation
So restriking operation is done for the accurate design of the part by restrike the press on the
part placed at the die.
PUNCHING/PIERCING: Punching is operation in which the punch can be made on the
part for the complete accuracy of it. During the punching the punches can be made on the part
because punches can be necessary according to the construction and working of it, because
without punches a part cant be fit into the car, so the punches are necessary according to the
constructional accuracy of it. After the operation of restrike the unloader picks the part from
the press and put it on the transfer belt which transfer it up to the another press where the
punching operation can be done. The loader takes the part from the belt and put it on the die
which is placed at the M.B. the upper part of the M.B. contains a die on it with the punches so
that when it strike on the lower die the punches can be made on the part according to the
construction of the die. So the punching operation is necessary according to the construction
of the part. The press works fully automatically and the different parts of the press such as
loader- unloader, transfer belt works automatically and plays an important role for the
construction of the part during the all operations of the press. The lubricating system is also
necessary for the accurate working of the press because without the complete and accurate
lubrication it can’t be possible to drive such kind of heavier press. The punching operation is
the last operation that can be done in the press shop and the die used for the punching
operation is of 400 Tones and upper die strike on the lower die with the pressure of 400
Tones and this pressure can be maintained by the air cylinders which are placed at the top of
the press. The part which is to be punched is complete in its construction and then sends it to
27
the quality check department for checking the accuracy and the defects producing during the
press shop operations. The part manufactured after the press shop operation is:
Fig 2.14: Complete Structure Of the Part
So during the Press Shop Department the four operations can be done
(i) Drawing
(ii) Trimming
(iii) Restrike
(iv) Punching/Piercing
After these four operations the part is completely ready according the construction and shape
of it. These four operations can be done on the dies of different loads the die used for the
Drawing Operation is of 800 Tones and the presses used for the remaining three operations
are of 400 Tones.
WELDING OPERATION: After the press shop operation the part is ready for adding the
different nut and bolts to be attached on it the part is sends to the welding section where the
spot welding can done on it. The Spot Welding can be done on it with two different kind of
welding:
28
(i) I.T. Gun Spot Welding
(ii) Non-I.T. Gun Spot Welding
(i) I.T. Gun Spot Welding: In I.T. Gun Spot Welding the spot welding can be done
with the help of a gun which contain the transformer in it. This kind of press
called as the I.T. Gun and the spot welding can do on it more easily as compare to
the other welding operations. The gun used for the I.T. Gun Spot Welding is:
Fig 2.15: I.T. Gun
(ii) Non I.T. Gun Spot Welding: In Non I.T. Gun Spot Welding operation the gun
used for spot welding does not contain transformer in it. The transformer is placed
outside of the gun. The name of the Non I.T. Gun is Non Integrated Transformer
Gun for spot welding. The gun used for Non I.T. Gun Spot Welding is:
Fig 2.16: Non I.T. Gun
29
Spot Welding can be done on the parts because it support the aerodynamic condition because
it is light in weight as comparison to the other welding techniques and its cost is less as
compare to other welding techniques.
After the welding process the part is sends to the final Quality Section where the quality of
the part and the accuracy of the part can be checked.
QUALITY SECTION: After the welding process the part is sends to the quality section
where the quality checker checks the quality and accuracy of the part because it is essential to
check the accuracy of part. The defects can be checked at that department because it is
necessary that a part should be accurate because without the accuracy it can’t be fitted into
the car. So it is necessary to checked out and solves these problems of the part the certain
defects that can be produced on the surface of the sheet during the press shop operations are:
(i) Overlap
(ii) Cracks
(iii) Wrinkle
(iv) Deformation
(v) Dent
These are the different defects that produced on the surface of the sheet during the press
operation such as drawing, trimming, restriking and punching. During these operations these
defects can produced so it is necessary to check these defects because these defects are not to
be favorable according to the structure of the part. So in quality checking section the checker
check this defects and solves these by different operations.
So this is the manufacturing process of the parts in which following three stages can be used:
(i) Press Shop Operations
(ii) Welding Shop Operations
(iii) Quality Checking Section
And after these three stages the part is ready for the supply and fitted into the car. So this is
the manufacturing process of the different parts.
30
CHAPTER-3
RESULTS & DISCUSSION
3.1 RESULTS:
3.1.1 Successful Development Of The Part: In the final we getting the result of the
successful development of the part. The part can be developed according to its profile which
is provided by the company to the engineers. According to its structure a die can be used for
the manufacturing of the part. For the manufacturing of the different parts different dies can
be used which are according to the shape of the part. The die is loaded on the M.B. and M.B.
can be placed inside the press as the lower unit and a upper portion of the die can be attached
to the upper M.B. with the help of studs. When the die is loaded then the complete automatic
process of the press starts and the pressure starts creating in the cylinders which are attached
at the top portion of the press. When the pressure completes then the upper die completes its
stroke and the single- single operations can be completed on different presses. The presses
used for these different operations are of different pressures the press used for the drawing
operation is of 800 Tones and the presses used for the remaining operations are of 400 Tones
that means the upper die strikes on the lower one with that pressure. The damps produced in
the press by this strike are absorbed by the damping unit which is under the cushion bed. The
M.B. is placed on the cushion bed and the damps can be absorbed by the damping unit. After
the every operation complete the part sends to the welding shop where the nut and bolts are
attached to the part according to the constructional detail of the part with the help of the spot
welding and at last the part is checked by the quality checkers and ready for delivery. So this
is the successful development of the part.
3.1.2 Get The Chance To Gain The Knowledge: After watching the complete
phenomenon of manufacturing of part we are able to getting the knowledge about the
different press operation such as drawing, trimming, restriking and punching. The different
part of the die works in a different manner and these are automatically done so after watching
these operations we are able to get the knowledge of different press operations.
31
After the different press phenomenon the different welding operations are
performed on it. The welding operation is used is the Spot Welding operation in which spot
welding can be done in different two ways:
(i) I.T. Gun
(ii) Non I.T. Gun
These are the two welding operation which are used for the spot welding so we get the
knowledge about the different spot welding techniques and machines which are used for spot
welding. By watching this complete we are able to get the knowledge of the different
processes that can be used in the factory for the manufacturing of different parts. So after
getting the complete training we get the knowledge of different processes.
3.2 DISCUSSIONS:
3.2.1 Defects Produced In Sheet: During discussion we discuss about the problem
facing during the manufacturing process of the different parts. Basically the main problem
can be faced is of different defects produced during the manufacturing phenomenon. The
different defects produced are:
(i) Wrinkle
(ii) Overlapping
(iii) Crack
(iv) Deformation
(v) Dent.
These are the main problems that are faced during the manufacturing process of part.
These defects can be discussed during the training
32
Fig 3.1: Defects Produced In The Sheet
3.2.2 Problem Produced In The Presses: There are different problem that
produced during the working condition of press and these defects can be studied or
discussed during training. The different defects produced in the presses are :
(i) Lubrication Problem
(ii) Pressure Problem
These are the problems that are produced during the working condition of the press. So
these defects can be discussed or solved out during training.
33
CHAPTER-4
CONCLUSION
In conclusion we are discussed to solve the problems produced during the working condition
of the press and manufacturing of the parts. To solve the defects produced on the surface of
the sheet during different press operations different processes can be used if the damage is
small and it can easily be repaired then it can be machined and repaired it but if the defect is
not be able to correct then the sheet can be thrown into the scrap. If the problems are small
and it can easily be repaired then different operations such as hammering, machining can be
used. After applying these processes the defects can be removed the surface of sheet because
without removing these defects it can’t be possible to use these parts. A defected piece can’t
be used in the manufacturing of the car so it is necessary to remove theses defects. In
conclusion we discussed the process used for the removal of the defects.
There are certain defects produced during the working of press. The different defects
produced during the press operation are lubrication problem, less pressure produced in the
cylinders. It is necessary to solve these problems because without solving these problems the
press can’t work automatically. If any operation of the press stops working then press stops
working so it is necessary to solve these problems. Sometimes the pump of lubrication stop
working and the press stops working. So this effect can be checked out and clear it so that the
press should work properly. Sometimes the cylinder cannot produce proper pressure for the
stroke of the die so it is necessary to solve this problem that the press should stroke properly.
The pump stops working and the pressure stops producing in the cylinders and due to this the
press stops working so we find out the problem and solve this so that press should work
properly.
So these are the basic conclusions that are made to solve the problems produced during the
different operations.
