Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

manufacturing of sheet metal components, welded assemblies at Gurgaon.
LOCATION –
Sector 36, Mohammadpur Jharsa, Near Khandsa Road,
Gurgaon – 122 001
Haryana.
OPERATIONS AND FACILITIES –
1)Press Shop - 20T to 2500T Presses – Mechanically and Hydraulic press.
2)Weld Shop – MIG welding ,Spot Welding and Robotic Projection Welding .
4. MAIN PROCESS INVOLVED IN PRODUCT FORMATION-
1)From customer side-
- Quotation of product
- Provide data of product
2) Die department –
- Analyze the data provided from customer
- Conversion of 2-d data into 3-d by designing team
- Die layout and no. of dies required
- Dummy pattern manufacturing
- Casting to form die
- After verifying all the dies, all are assemble together to form main die
- Many trials to be done to check the accuracy of product
- Finally the female die is fixed at lower side of pressing machine and male die
is clamp at upper moving side.
3)Manufacturing department –
- all pressing machines are automatically controlled
- nut, bolt are attached by different welding processes
4)Quality department –
- main work is to ensure that product will be perfectly fit at its desired location
- many checks are performed to make products defect free
Finally the product is delivered to customer.
5. PRODUCTION DEPARTMENT -
Main production of parts is carried out by pressing machine. JBM has largest
pressing shop of Asia and have total of 10 different lines of pressing machines.
The plant has total ten lines comprising of different forging machines of different
tones.
The main reason why JBM is developing very fast is because of innovative
technology they are using in their industries which are totally automatic and are
less dependent on human power. All pressing machines are imported from Japan
companies like KOMATSU, ISGEC etc.
Out of all 10 lines only one line has Hydraulic pressing machine and rest 9 are
mechanically pressing machine. Hydraulic pressing is very slow process and is
used for component which require large bending.
6. Hydraulic Presses
Hydraulic presses are a powerful class of machine tools, they derive the energy
they deliver through hydraulic pressure. Fluid pressure, in a particular chamber,
can be increased or decreased by the use of pumps, and valves. Sometimes
devices and systems may be used to increase the capacity of the pumps in more
powerful presses. These presses can operate over a long distance and at a
constant speed. Hydraulic presses are generally slower relative to other press
machine types. This involves longer contact with the work, therefore the cooling
of the work can be an issue when hot forming a part with hydraulic force.
Hydraulic presses are capable of being the most powerful class of presses. Some
may be as large as buildings, and can deliver awesome pressure. The largest
hydraulic presses are capable of applying 75,000 tons of force. The hydraulic press
shown is being used to manufacture a metal forging. Extrusion is also a very
common use for such a press, although extrusion is often performed horizontally.
7. Mechanical Presses
Mechanical presses belong to a class of machine tools that encompass a wide
range of different machine types. Primarily, the mechanical press transforms the
rotational force of a motor into a translational force vector that performs the
pressing action. Therefore, the energy in a mechanical press comes from the
motor. These types of presses are generally faster than hydraulic or screw
presses, (actually the screw press may also be classified as a mechanical press).
Unlike some presses, in a mechanical press, the application of force varies in both
speed and magnitude throughout the distance of the stroke. When performing a
manufacturing operation using a mechanical press, the correct range of the stroke
is essential.
Presses are chosen based on the characteristics of the manufacturing process.
Mechanical press machine tools are commonly used in metal forging
manufacture, and sheet metal working. The desired application of force will
dictate the type of machine required. Extrusion will often necessitate a more
consistent force over a longer distance. However, a mechanical press may often
be a good choice for impact extrusion, since a fast, quickly repeatable application
of force over a limited distance is what is needed for that type of manufacturing
process. The most powerful mechanical presses in modern manufacturing
industry will have a press capacity of about 12,000 tons.
8. BASIC OPERATIONS PERFORMED BY PRESSING MACHINES –
Mainly four types of operations are performed in sequence in 4 different
machines of 1 line. These operations depend on type of die we are using. These
basic operations are –
1)Drawing – in this initial shape formation of part take place.
2)Trimming – this involve cutting of extra part of sample.
3)Piercing – in this holes formation and bending of sample take place.
4)Parting – in this the whole plate is divided into two parts.
Mechanically pressing machine –
Company name – KOMATSU
Have 4 different machines in one line each of capacity 1200 Ton.
Hydraulic pressing machine –
Company name – ISGEC
Have single machine with capacity of 1000 Ton.
9. Types of operation –
1 :- Blanking – sheet metal cutting to separate piece(called a blank) from
surrounding stock.
2 :- Trimming – Cutting processes are those in which a piece of sheet metal is
separated by applying a great enough force to caused the material to fail.
3 :- Piercing –
4 :- Notching – Notching is a shearing process during which a metal scrap piece is
removed from the outside edge of a metal workpiece.
5 :- Flanging – Flanging is a process of bending the edges of sheet metals
6 :- shaving –
10. JBM is largest vendor company of different auto companies like MSIL, Eicher,
Ashok Leyland, Bajaj Auto Ltd, Fiat, Ford, General Motors Corporation, Honda,
Hero, JCB, Mahindra etc .

12. WELDING –
RESISTANCE SPOT WELDING-
Resistance welding is a welding process which join the metals with the heat
obtained from resistance offered by the work to the flow of electrical current
through the parts being joined.
A pair of copper alloy electrodes conducts electrical current through the two
sheets pressed between the interface. The two sheets offer maximum resistance
to the flow of current, this generates heat, the interface melts and consequently
solidifies under the pressures of the two electrodes, thereby joining the two
sheets at the spot that was under the two electrodes.
13. TYPES OF GUN USED IN SPOT WELDING
X- TYPE GUN
Also known as "scissors" or "pinch".
C-TYPE GUN
C guns are generally the cheapest and the most commonly used.
14. PROJECTION WELDING
Nut projection welding
Projection Welding Is A Type Of Resistance Welding. High current in less time
is the main feature of this welding.
15. QUALITY DEPARTMENT -
This department has very crucial as well as very important role in company’s
development. A small defect in product can cause big loss economically.
The whole system work as- suppose company get an order of 1 lakh pieces of
patch pieces then the first product from the machine is verified by engineers by
“panel checker” and if it is found accurate then all other product are only visually
checked by workers.
Engineers have all the basic data about product like dimensions, distance
between holes etc , which help them in verifying the product on panel checker.
If product is not found as per their requirement then it is corrected by hammering
or other methods.
In JBM they follow the following process-
1:- In process quality – Engineers check the first piece by panel checker. Their
main motto is to check –
- Whether the gap between sample and panel checker is continuous or not.
- distance between holes and position of hole.
- any trimming of extra part is required or not.
16. 2:- FOA(First of approval) – after the first inspection all others product are only
visually checked by workers. They are provided with a type of “defect album” in
which the possible types of defects that can occur are written. Therefore the duty
of worker is to visually check only that area which have the possibility of any type
of defects. Main motto of this is to check any type of crack, flange, dent, wrinkle,
hole shift etc.
Different types of defects –
1) Crack
2) Flange cut
3) Dent
4) Wrinkle
5) Burr
6) Hole shift
17. DIE MAINTAINENCE DEPARTMENT -
A die consist of two parts one is the female part on which steel plate is to placed.
The male part apply force on the sheet metal plate and transfer it in the required
shape.
The main work under this department is to insure that formation of die is such
that the part form is exact same as the required. Because a very small error can
make very high loss to company.
Depend on the type of process ,selection of the die is to made like for cutting we
have different type and like piercing we have different . For single product we
have to do pressing, cutting, piercing, final shaping therefore approximate 8 dies
are required.
For every single order from parent company, new die needs to be made and after
completion of that order that dies have no use and are sold in scrap.
18. Basically a die consist of two pairs one is called female part which is the lower
part and the other one is called male part which is the upper one.
Female part of a die is fixed and male part move up and down. Some important
component involved are:-
1)Cushion pin or pressure pin :- A pin used in conjunction with an air cushion
that transfers pressure from the air cushion to the bottom of the die.
2) Air Cushion :-An air-actuated press accessory that is placed below or inside die
block, which is used to increase pressure on the die using pressure pins. The air
cushion can also be used to lift the part out of the die.
19. Types of dies:
The dies may be classified according to the type of press operation and according
to the method of operation.
(A): According to type of press operation:
According to this criterion , the dies may be classified as cutting dies and forming
dies.
1: Cutting Dies:
These dies are used to cut the metal. They utilize the cutting or shearing action.
The common cutting dies are : blanking dies , perforating dies , notching dies ,
trimming , shaving and nibbling dies.
2: Forming Dies:
These dies change the appearance of the blank without removing any stock.
Theses dies include bending, drawing and squeezing dies etc.
(B) According to the method of operation:
According to this criterion, the dies may be classified as : single operation or
simple dies , compound dies etc.
1: Simple Dies:
Simple dies or single action dies perform single operation for each stroke of the
press slide. The operation may be one of the operation listed under cutting or
forming dies.
2: Compound Dies:
In these dies, two or more operations may be performed at one station. Such dies
are considered as cutting tools since, only cutting operations are carried out.
Compound dies are more accurate and economical in production as compared to
single operation dies.
3: Progressive Dies:
A progressive or follow on die has a series of operations. At each station , an
operation is performed on a work piece during a stroke of the press. Between
stroke the piece in the metal strip is transferred to the next station. A finished
20. work piece is made at each stroke of the press. While the piercing punch cuts a
hole in the stroke , the blanking punch blanks out a portion of the metal in which
a hole had been pierced at a previous station. Thus after the first stroke , when
only a hole will be punched , each stroke of the press produces a finished washer.
21. CONCLUSION
It’s always a great opportunity to experience the valuable exposure of an
industry. There is lot of difference between the Theories and Practices. This
Training enables me to understand the aspects of professional life. I like the
working environment followed at JAI BHARAT MARUTI PVT. LTD. and come to
know how to deal with our colleagues. The company’s members are well cultured
& well mannered.
An effective process is followed at JBM but it would become more valuable and
impressive by implementing certain efficient measures. The company is
constantly focusing on providing better services, quality and reliability to
customers, and running successfully in this era of competition.
