AIM: TO MAKE A SQUARE

TOOLS REQUIRED:

1. STEEL RULE
2. SCRIBER, DOT PUNCH
3. HACK SAW BLADE AND FRAME
4. BALL PEEN HAMMER
5. TRY SQUARE
6. 12" BASTARD FLAT FILE
7. 6" SMOOTH FLAT FILE

MATERIALS REQUIRED

1. 50 x 50 x 6 M. S. FLAT
2. MARKING BLUE
3. CLEANING BRUSH

PROCEDURE:

1. INITIALLY CUT OFF THE WORK PIECE FROM RAW MATERIAL BY USING A HACK SAW FRAME AND A BLADE. THE MARKING IS DONE BY A SCRIBER AND STEEL RULE.

2. THEN DEBURR ALL THE EDGES BY USING A FILE.

3. AFTER DEBURRING HOLD THE JOB ON THE BENCH VICE TIGHTLY.

4. THEN FILE ANY ONE EDGE TO BECOME FLAT. IT IS CHEECKED BY USING A TRY SQUARE. ALSO THE FILING IS DONE BY BOTH 6" AND 12" FLAT FILES.

5. THEN FILE THE ADJACENT SIDE MUTUALLY PERPENDICULAR TO EACH OTHER BY USING 12" BASTARD FLAT FILE. THE PERPENDICULARITY WAS CHECKED BY A TRY SQUARE.

6. AFTER COMPLETING THE DATUM SIDES, MARK THE LENGTH AND HEIGHT OF 45mm. BY USING A VERNIER HEIGHT GAUGE. ALSO APPLY THE MARKING BLUE INTO THE SURFACES OF JOB FOR BETTER CLARITY.

7. THEN PUNCH THE MARKED LINES BY USING A DOT PUNCH AND BALL PEEN HAMMER.

8. AFTER MARKING, CUT OFF THE UN-WANTED AREA BY USING HACK SAW FRAME AND BLADE.

9.THEN FILE THE OTHER TWO SIDES MUTUALLY PERPENDICULAR TO EACH OTHER BY USING A 12" BASTARD FLAT FILE.

10. AT LAST THE FINISHING FILING WAS DONE BY 6" SMOOTH FLAT FILE FOR GETTING SMOOTH SURFACES.

11. THEN SUBMIT THE WORK PIECE FOR INSPECTION, AFTER 1mm. CHAMFERING AND DEBURRING.

RESULT:

 THE FILING OF SQUARE IS DONE SUCCESSFULLY AS PER THE DIMENSIN OF 5mm. THICK AND SIDES OF 45mm. LENGTH

ENGINE COMPONENTS 1. CYLINDER BLOCK      The cylinder block is the main body of the engine. Cylinder head is mounted on the cylinder block. It houses iniet and exhaus valves. Crank case is attached to the bottom of the cylinder block. Crank case supports the crank shaft. Oil pan is attached to the bottom of the crank case. Cylinder block contains large cylindrical holes called cylinder bore. The cylinders are accurately finished to accommodate pistons. The space above the piston inside the cylinder at TDC called the combustion chamber. Combustion of fuel inside this space, high pressure and temperature will be developed inside the cylinder. Therefore, it should be made of material which can resist high pressure and temperature (2800°C). In water jackets has around the cylinders for the circulation cooling water to absorb the temperature while running of an engine. 2. CYLINDER HEAD Cylinder head is a separate casting placed on top of the cylinder block by studs and nuts. It houses the i

INTRODUCTION TO ENGINE ( for NCVT)

Engine : It acts as the power unit. The internal combustion engine is the most commonly used in automobiles. It is of two types ; (i) Spark ignition (ii) Compression ignition.         Both engines are called heat engines. A steam engine is an external combustion engine because the fuel is burned outside the engine. The principle of working of an external combustion engine is shown in the figure below. COMPARISON BETWEEN INTERNAL AND EXTERNAL COMBUSTION ENGINES      The internal combustion engine is an engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber. In an internal combustion engine the expansion of the high temperature and pressure gases, which are produced by the combustion, directly applies force to a movable component of the engine, such as the pistons and by moving it over a distance, generate useful mechanical energy.          The internal combustion engine is quite different from external combustion engines, such
