PROJECT WORKS AND IN HAND EXPERIENCE

5.1. PROJECT AT TMPVL

5.1.1. PLC Training

During my internship period at TMPVL I got an opportunity of getting PLC


tanning from MR. Radha Raman Sharma. PLC stands for Programmable Logic
Controllers.
Definition: A digitally operating electronic apparatus which uses a
programmable memory for the internal storage of instructions by implementing
specific functions such as logic sequencing, timing, counting, and arithmetic to
control various types of machine or processes through digital or analog input/output
modules.
Basically, PLC are industrial computers, with
various inputs and outputs, used to control and monitor
industrial equipment bade on custom programming,
PLC were designed to replace Relay Logic, they can
perform the sequential operations that were previously
implemented with relays, timers, etc. Fig.5.1 PLC

PLCs come in many different sizes and form factors. Some are small enough
to fit in your pocket, while others are large enough to require their own heavy-duty
racks to mount. Some PLCs are more modular, with only basic I/O (input and
Outputs), but can be customized with additional back planes and function modules
to fit different types of industrial applications.
PLCs are widely used in a variety of industries because they are fast, easy to
operate, and considered easy to program. There are five standard PLC programming
language. The most commonly used language is Ladder Logic, but it is also possible
to use function Block Diagrams, Sequential Function /charts, Structured Text or
Instruction Lists to achieve the same functionality.

5.1.2. Blank Rejection

Blank panel of different size and shape come from different vendor for different
body panels, these blanks are unloaded from the commercial vehicle with the help
of the OM’s 8T forklift and then these blanks are stored in the Blank Storage area
and then loaded in the Blank Lifter Crane at the Front of the Line of the High-
Tandem Press Machine.
Some blank panels get damage during:
 At the time of loading form the vender,
 During the time of transportation,
 At the time of unloading from the trailer,
 At the time of stacking the blanks in the racks of the Blank Storage area,
 During the time of loading the blanks in the Blank Lifter Crane at the Front
Line.

The most common damages in the blank panel are:

 Burr
 Rusting/
 Deformation/Damage
 Scratches
 Wrinkles/Material Folding
 Cracks

All the blank panel are checked before taking the delivery by a skilled worker
and the worker keeps the data of this rejected blank panels in a book, this rejected
blank panels are sent to the scrap.

My project was to collect the data of this rejected blank panels of the past 6
months and make a excel sheet of the data and suggest solution for the problem.

Some of the suggested solution to this problem are:

 To add a dummy panel at the bottom and top of the blank stake,
 To install rubber cover to the forks of the forklift
 To used cam to keep the panels in place at the time of transportation.

5.1.3. Loss Report of End of Line

There are a number of reason due to which the Press line stopes, it could be due to
sensor fault in the die or due to any defect on the pressed panel of dur to some pressure
problem in the press or the feeders’ cups or due to restacking of the blanks or due to
the blank pallet. My project was to make a report on the loss report on the end of line
and the reason due to which the line stopped by the end of line.
On an average the loss time due to the end of line is about 70-75 minutes (if any
major defect or problem does not show’s up) in A shift, this also includes the lunch
and tea break of the workers.
Some of the reasons due to which the line was stopped are:
 Quality check of the first panel (Quality department checks for any defect and
counts the number of holes on the panel).
 The line also stop’s due to the shortage of blank pallet or the forklift operator
delays to bring the blank pallet.
 If any defect is detected then the line is stopped and the required correction is
done by the respected department.
 The line is also stopped due to the panel stacking up at the end line conveyer.

Fig. 5.7 Photo of End of Line

Solution for the loss of time at the end of line:


 The roller needs to be changed of the conveyer for pallet.
 The blank pallet should be available on time.
 Ideal number of man power should be there and with proper coordination.

5.1.4. Assistance in Project of Supply Chain

An intern from the Supply chain department had a project on the weight of the blank
panels and the number of blanks inserted in and the number of panels pressed. Different
blank panels have different weight and gauge. This wight and gauge depends of the
panel’s uses and the amount of stress and load it going to experience by the press.
The weight of Tiago panels and their gauge are listed below:
Panel name Panel Weight(kg) Panel Gauge(mm)
Fender LH & RH 5.0 0.63
BSO LH & RH 18.5 0.7
FDO LH & RH 8.2 0.63
RDO LH & RH 7.0 0.63
RDI LH & RH 8.1 0.7
HOOD Inner 6.5 0.6
TGI 9.1 0.7
FDI LH & RH 9.0 0.7
HOOD Outer 8.0 0.63
Front Foor 14.7 0.7
ROOF 12.7 0.7
TGO 9.4 0.7
Table 5.4 Blank Panel Weight and Gauge size

The number of the blank inserted in the press at the front of line and the number of
pressed panels from the end of line conveyer are not always same, because some time
there are faults in the press due to which the panel get stuck in the line and get damage
in such case the line is stopped and the panel are manually removed from the line.

2. End of Line: During the internship apart from the projects I also got an
opportunity to get in-hand experience to operate the KUMATSU press from
the end of the line, observe Material Quality of the pressed panels and
manage the workers. At the end of line there is a Line Operation Panel
through were all the operation of the line from the press 1 (OP 10) to the end
of the line conveyer all are controlled.
On the Line Operation Panel their sit’s an operator who operates all the
operation for the press 1 to the end of line conveyer belt, the operator also
keeps a record of the hourly production control chat book.

The hourly production control chart bool includes all the data related to the panel
produced, faults that came during the production and loss of time data with reason of
every hour of production. The Line Operation Panel has a screen which shows all the
data of the press line (including the production count of the current panel, total panel
produced, line speed, it shows where the fault is and which type of fault it is), we can
also reset the cycle, stop the press and re-set the operation.

Fig.5.8 Line Operation Panel Fig.5.9 Hourly Production Check List

3. Blank Storage area: All the Blank coming from the venders are unloaded and
checked, the data of the vehicle is written with the total number of panels in the pallet.
I was assigned to assist the supervisor in keeping a track of the data and to guide the
worker.
4. Die Maintenance: Observed the regular maintenance of the dies, also the online die
maintenance and also got to observe the matching of the updated OP 30 die of the
Tiago RDI from Pune plant.

Fig.5.10 Die Maintenance


5. Press Maintenance: In the slider of the left arm of the Feeder 1 two screw were broke
and needed to be replace, due to which the press was shut in the A shift. Firstly, the
Feeders slider part was secure and then detached, then all the helical screws were
fastened and the 2 screws were replaced.

5.2.1. General Service

The General Service includes:


 Oil and oil filter change
 Break-pad and disc check
 Break bleeding
 Coolant top-up
 Air filter cleaning/change
 A.C filter change
 Washer fluid top-up
 Battery check
 Door greasing
 Washing

There were vehicles which used to come for only


oil -change. As the Mundra workshop is equipped
only for general services, the major services were
done at the Bhuj dealership’s workshop

Fig.5.11 General service

5.2.2. PDI

The Pre-Delivery Inspection (PDI) is done to ensure that the vehicle is in perfect
condition and there is no damage or defect before delivering the car to the
customer. As the new cars are delivered at the Bhuj dealership so a PDI is done
there and then the car is brought to the Mundra Showroom by road (with the
customer concern), then at the Mundra showroom the cars is washed and the outer
body is checked, the electronic are checked, the under body of the car is checked
by lifting it on the 2-post hydraulic lift for any leakage of damage/defect and also
the fluid are checked of the car (engine oil, brake oil, coolant and washer fluid).
Once the car’s PDI is done the car is ready for delivery.

6.2. SAFETY PRECAUTIONS AT B. MANGATRAM,

MAHINDRA

The work shop follows majorly to types of safety precautions:


1. Vehicle safety: The vehicle safety includes the safety precautions that the
employs follow to keep the vehicle safe from damages, such safety
precautions are:
 Proper body covers should be used during work of the vehicles to
protect it from scratches.
 The vehicle should be checked that it safely secured before lifting
the lift.
 The vehicles in the workshop are derived at the waking speed.
 Special tools are used for specific tasks.
2. Employs safety:

311419 Suggestions on The Current System

CHAPTER: 7

SUGGESTIONS ON THE CURRENT SYSTEM

7.1. MATERIAL QUALITY CHECK AT END OF LINE

The Material Quality of panels is done by skilled workers, this works check
for the defects/damage in the panels with their naked eye under light and with
the touch of their skilled hands. They are able to detect majority of the
defect/damages but the implementation of Morden technology can be done.
The use of smart inspection techniques can be implemented such as the 3D
scanning and infra-red camera inspection to ensure supreme levels of build
quality.
7.2. SUPER MARKET

The current system of the supermarket follows a marking of the area for the
panel at the top of the shade with the help of boards but marking of the floor
for each panel would be more convent for the forklift drivers. In addition to
that magnetic badges with proper iron slots could be used in place of stickers
on the pallet (rework, ok and rejection indication).
7.3. BLANK STORAGE AREA

The racks used for the storage of stake of blank panel in the Blank storage
area causes damage to the blanks at the bottom, so thick sheet of rubber could
be used to reduce the damage.
Also, the used of rubber cover for the forklift could be done to decrease the
chance of damage of the panel during operation.
7.4. ADDITION OF NEW EQUIPMENTS/TOOLS AND

MANPOWER AT B. MANGATRAM, MUNDRA

The workshop requires a list of new equipment’s, tools and manpower for
doing major service with the on-going general service. Various special tools
and equipment’s can be introduced in the workshop (as the workshop has ample
space for the new equipment’s).

46
Gujrat Technological University Government Engineering College, Rajkot
311419 Suggestions on The Current System

List of tool and Equipment’s required:


 Wheel Alignment Machine,

CONCLUSION AND LEARNING OUTCOMES

8.1. CONCLUSION AND LEARNING OUTCOME AT TMPVL,

SANAND

The internship at TMPVL has been an excellent opportunity for me. During the
course of this internship, I got to connect the bridge between my theoretical
knowledge and practical work. The internship served me best with the best
knowledge of working in manufacturing plant under the banner of such prestigious
company.
I feel enrich in more than one way, it gave me the experience of how to manage
manpower, how to do planning according to the resources available. my allotment
to the Press Shop gave me the experience on how are the body panels are made from
a blank sheet of sheet. I believe that I have been trained not only in the project
activates given to me, but also trained in time management, industrial management,
communication and soft skills, safety and also maintenance related work. It also
helped me to get in touch with the industrial environment and the value of time and
professionalism.

8.2. CONCLUSION AND LEARNING OUTCOME AT B.

MANGATRAM, MUNDRA

The period of internship at B. Mangatram, Mundra was short but it gave me a lot
of experience of a workshop and the enhanced my skills both theoretical and
practical. The internship helped me to apply my theoretical knowledge in the
practical, while working with the skilled workers. This internship also taught me
various tricks that the mechanics use will performing service to save effort and time.
The primary objective of this 12-weeks of internship was to gather real-life
working experience and put the theoretical knowledge in practice and I consider
that the objective was achieved. Over-all, it has been such a great experience and I
think the knowledge I got here will completely help me in my career.
