Machining process: Machining is the process of cold working the metals into different shapes by using different types of machine tools. This process is mainly used to bring the metal objects produced by means of different fabrication techniques to final dimensions. Machining is accomplished with the use of machines known as machine tools. For production of variety of machined surfaces different types of machine tools have been developed. The kind of surface produced depends upon the shape of cutting, the path of the tool as it passes through the material or both. Depending on them metal cutting processes are called either turning of planning or boring or other operations performed by machine tools like lathe, shaper, planer, drill, miller, grinder etc. Classification of machining processes: Machining process are material removing operations in which the desired shape and surface finish on the finished product are obtained by removing surplus material. 1.

Types of clutches In my previous post I discussed about the clutch mechanism and what is clutch so here I don’t want to waste your time, so here I’m going to tell about types of clutches briefly clutches are basically classified according to their construction and performance different types of clutches are 1.        Multiple plate clutch 2.        Single plate clutch 3.        Wet vs. dry 4.        Centrifugal 5.        Cone clutch These are the major types of clutches 1.    multiple plate clutch Multiplate   are mainly used in large trucks and racing cars if torque transmission is necessary but the diameter is limited these are also used in automatic transmission and motor cycles in this type of clutches a number   of parallel discs of metal and friction material are arranged to transmit the driv...

CLUTCH Clutch is a mechanical device it’s one the major part in transmission power system .it provides for the transmission of power from one component to another component, its placed in between the flywheel and gear box .Next to the flywheel and before to the gear box transmit power during engage condition main purpose of the clutch is control the amount of motion whenever it needs, Mechanism of clutch It’s the simplest mechanism connect and disconnect two rotating shafts (drive shafts or line shaft).One shaft attached to motor or engine which provides power its input shaft (driving member)and the other shaft gear box etc.(the driven member)provides output power of work. Clutch is an unit it contains main parts inside into it Material used for clutch As i already said clutch is a unit it contains many parts each parts are made with different materials .The outer case of the clutch is made up of cast iron, please wait for my next post so you can get to know more about clutc...

Flywheel The flywheel is a disk or wheel attached to the crank, forming an inertial mass that stores rotational energy. In engines with only a single cylinder the flywheel is essential to carry energy over the power stroke into a subsequent compression stroke.   Flywheel mostly present in reciprocating engines to smooth out the power delivery over each rotation of the crank and in most automotive engines also mounts a gear ring for a starter. The rotational inertia of the flywheel also allows a much slower minimum unloaded speed and also improves the smoothness at idle .the flywheel may also perform a part of the balancing of the system and so by itself be out of balance although most engines will use a neutral balance for the fly wheel ,enabling it to be balance in a separate operation. The flywheel is also used as a mounting for the clutch or a torque converter in most automotive applications. Material Flywheel   are typically made by steel and also carbon fiber is u...

http://en.wikipedia.org CRANKCASE         The main body of the engine to which the cylinder are attached and which contains the crankshaft and crankshaft bearings is called crankcase.This members also holds other parts in alignment and resists the explosion and intertia forces.It also protects the parts from dirt etc. In the crankcase only the engine oil are stored in self lubricate syst em the crankcase play an important role the scoop used for splashing to the engive wall are taking oil from the crankcase only so I play a majore role in lubrication system      Crankcase forming an engine block ,crankcase  are the basic engine structural component   crankcase often has an opening in the bottom to which an oil pan is attached a gasketed bolted joint. Material used for crankcase  Material which is used for making crankcase are engine block mostly cast aluminium crankcase are made via sand casting ...

CRANKSHAFT In my all post I’m telling that this the major part you definitely get bored of this now also I’m going to say the same line crankshaft another major part in the engine but in this post bit I’m going to some technical words so you can understand better the mechanism and parts description .Crankshaft part which converts the reciprocating motion of the piston into rotary motion .This motion of the piston is transmitted to the crank by the connecting rod. The crank shaft subjected to the torsional and bending stresses and is supported on the crankcase structure on large bearing .These crankshaft bearings are known as main bearings. The number of bearings varies depending on the dynamic load on it. For example a four-cylinder engine crank case may have two, three or five bearings. Parts in crankshaft Crankshaft contains many parts they are   crankpins, crank arms, crank journals, and driving ends the crankshaft attached to the fly wheel to reduce the pulsation char...

Connecting Rod Connecting rod in name itself you can understand it connect something that something is nothing but it connects the piston and the crankshaft and also its called as Conrod .Main purpose of the connecting rod was converting the reciprocating motion into rotary motion getting reciprocating motion from the piston and giving rotary motion to the crankshaft .Its is rigid ,it may transmit either push and pull i.e. pushing and pulling done on the piston Construction Major parts in the connecting rod is big eye end and small eye end, small end attaches to the the piston pin or gudgeon pin, the big end connected with the crankshaft ,the between the big end and crankshaft the bearings are placed Material used Connecting rod is the back bone for the engine if it breaks engine doesn’t work it stops suddenly   so connecting rod has to be rigid for that reason the material has to be chosen mostly connecting rod made by steel only but now a days its made by T6-2024 and ...

Piston Ring Piston rings are the majore parts in the piston it provide a dynamic seals for the piston,seal suppresses the leakage of   lubricants from the tribo system and also   provide   protection and cleanliness 3 piston rings are mounted on the piston Types of rings In the piston there are two kinds of rings mounted on the piston they are 1.        Oil ring 2.        Compression ring Compression Ring Compression ring act as a gas seal between the piston and the cylinder liner wall, preventing combustion gases from trailing down to the crankcase, the ring have certain pre-tension i.e. they have large free diameter than the cylinder liner,which assists the ring in conforming to the liner. Oil Ring Some mechanism    needed to distribute the oil evenly onto the liner ,The number of oil control rings in in ring pack is 1 or 2.Normally a single oil control ring is sufficient but o...

  Engine Piston Piston located inside the engine cylinder, it the major part of the engine   piston movement was reciprocating   motion it converts the pressure into a rotating motion it present in all type of engines external combustion engine,external combustion engine,steam engine etc… piston may be one or more according to engine type and size of the engine purpose of the piston was completing all the strokes of the engine in efficient manner example there are many types of strokes like 2 stroke ,4 stroke 6 stroke etc…. How Piston Works? Piston located in the combustion chamber when the combustion take place it happens above the piston head only during the combustion   the gases got expand pushing the piston to the bottom from the head   the power of pushing going to the shaft which the piston is connected over it the shaft is called crankshaft   its main work was converting reciprocating motion into rotary motion ,after reaching the bottom the ...

ENGINE An engine it’s a device which used to convert energy into mechanical motion ,first engine invented on 1712 it a steam engine power of steam used to produce mechanical work its named as newcomen steam engine which used to pump water from the mines ,for this reason only engine was invented in 18 Th century after asper the requirement engine evolved for different requirements   different types of engines are originated. ENGINE CLASSIFICATION Engines are classified according to different aspects 1.        According to types of combustion 2.        Types of stroke 3.        Types of fuel 4.        Types of piston arrangement According to types of combustion There are two types of combustion system 1.        Internal combustion (IC) Engine 2.        External combustion Engine I...
