INDUSTRY BACKGROUND

The Indian tractor industries as it now is a major segment of its engineering

industry. However till 1947, Indian firms assembling semi knocked down (SKD)

kits in collaboration with foreign manufactures met the tractor requirement of

the country largely through imports and partly. Though the first tractor company

was set up in India 1960, but the growth in real terms started from 1974, when the

government banned the import of the tractors. Today India is the largest tractor

producing and consuming country. In an effort to reduce imports and develop

indigenous technology, the government, permitted setting up of the major

manufacturing companies.

CRANK-CASE:

Crank–case is the housing for accommodating crank shaft and cam shaft. In

SWARAJ tractors, crank case is cast separately and attached to cylinder

block. The bottom face of crank case walls is flanged to strengthen the casing

and to provide a machined joint face for sump to be attached. Crank-shaft is

supported in the crank case through a number of bearings called main

bearings. The construction of the crank case has to be such as to provide very

high rigidity because it must provide reactions for the heavy forces set up to

10

gas pressure in the cylinders. The cylinder block is mounted above the crank

case. At the top of the cylinder block is attached the cylinder head. Attached to

crank case is sump, flywheel, gear casing, fuel filter, water separator etc.

The material of crank case is cast iron because it has following advantages:-

1. Good foundry material

2. High machinability

3. It does not warp under high temp. & pressure developed in cylinders

4. It is slightly porous nature as it retains better lubricant oil film

5. It does not wear too much

CYLINDER HEAD

Cylinder head is attached to the top of the cylinder block by means of studs

fixed to the block. The gaskets are used to provide a tight leak proof joint at

the interface of the head and the block. The cylinder head forms a combustion

chamfer above each cylinder. It also contains injector holes and cooling water

jackets. Besides valve openings are provided in the head. Upon which is also

mounted the complete value operation mechanism. In all the cylinder heads of

10

swaraj engines, the inlet and exhaust manifolds are placed on different sides of

the cylinder head, it is called offset cross-flow type. Detachable head type has

many other advantages over the integral construction.

1. From production point of view, the cylinder block casting with open bore

for the detachable type head, is much more simplified.

2. Operations like de carbonizing and value grinding are simplified

3. The comp. ratio can be changed slightly by changing the thickness of

gasket used between the block and the head. The material used for

cylinder head is cast – iron

There are separate sets of pipes attached to the cylinder head which carry

the air and the exhaust gases. These are called manifolds.

The cylinder has the nozzle bore in which the injector is inserted. The

function of injector is to inject the fuel in the cylinder in properly atomized

from and in proper quality. The cylinder head apart from having the inlet

and exhaust manifolds (attached to cylinder head) has a water outlet

manifold. On the top of cylinder head, is mounted the rocker arm, rockers

shaft, push rods, springs rocker cover etc. The cylinder head also contains

the inlet and exhaust valves.

There is a water jacket in the cylinder head for the circulation of cooling

water. The lubrication oil for the lubrication of rocker assembly enters

from Rocker supply hole. Where it enters through rocker supply hole

where it enters through rocker supply pipe from crank-case. RV2 and RV3

have the same cylinder head while RB30 and RB33 have the same. The S-15

has completely different cylinder head.

It is the application of statistical methods to the monitoring and control of a process to ensure that it operates at its full potential to produce conforming product. Under SPC, a process behaves predictably to produce as much conforming product as possible with the least possible waste.

HOW TO USE SPC

Statistical Process Control may be broadly broken down into three sets of activities: understanding the process; understanding the causes of variation; and elimination of the sources of special cause variation.

Statistical Process Control may be broadly broken down into three sets of activities: understanding the process; understanding the causes of variation; and elimination of the sources of special cause variation.

In understanding a process, the process is typically mapped out and the process is monitored using control charts. Control charts are used to identify variation that may be due to special causes, and to free the user from concern over variation due to common causes. This is a continuous, ongoing activity. When a process is stable and does not trigger any of the detection rules for a control chart, a process capability analysis may also be performed to predict the ability of the current process to produce conforming (i.e. within specification) product in the future.

When excessive variation is identified by the control chart detection rules, or the process capability is found lacking, additional effort is exerted to determine causes of that variance

Once the causes of variation have been quantified, effort is spent in eliminating those causes that are both statistically and practically significant

SPC on Sunkap Duplex machine(286.01)

Need : Variation in Size dimension 328+-0.1 and Dimension 15+- 0.1 from component to component (maximum Variation 0.25mm)

PROCEDURE1. Select the parameter (liner depth of cylinder block ) for which machine

capability is to be calculated.2. Give the SPC chart showing the upper scale tolerance limit & lower scale

tolerance limit to the operator.3. Operator is made to fill the readings on SPC chart at regular intervals.

ACTIVITY DONE1.Component inspection (10 nos.) carried out for dim 328 at 4 points .

2.After the inspection the whole data is feeded For calculating the Machine capability which is called as CM.

3.The CM comes out to be 0.36.

4. New Fixture for Sunkap was made for improving the CM of the sunkap machine.

5.Again the Component inspection (10 nos.) carried out for dim 328 at 4 points 6. Results are slightely better as the CM is increased to 1.37

10

7. Then the Component inspection (15 nos.) carried out for dim 328 at 4 points with different clamping pressure

8. Repeatbility Results are slightely better @ low clamping pressure

Project no:3Evaluate tool life of sunkap machine and Semi finish boring machine

10

Tool life can be define as the length of time that a cutting tool can function properly before it begins to fail.

PROCEDURE:

Tool life of each tool used in sunkap & finish boring machine is calculated by making list of each tool that is used on these machines to make the required component.

Tool list of each tool is provided on each machine & operator is asked to fill the date & time of tool change.

After the data is collected about the date and time of tool change the next step is to fill the data into the table for calculating the tool life of sunkap & finish boring machine.

Here are some table which i have up made for calculating the tool life .
