Slotter Machine is a resiprocating machine in which, the ram which holds the tool resiprocates in vertical direction and the cutting process is done only in the downward stroke and not in the downward stroke. This machine is similar to a shaper or planar machine. The working principle of Slotter Machine is same as that of Shaper Machine. The only difference between a shaper machine and slotter machine is…
A quick return mechanism is an system to produce a resiprocating effect such that time taken by system in return stroke is less time taken by it in the forward stroke.In quick return mechanism, a circular motion is converted into reciprocating motion just like crank and lever mechanism but it has return stroke time is…
Laser Beam Machining is a thermal machining process which uses laser beam to produce heat and remove material from workpiece. In this machining, metal is removed from workpiece by melting and vapourizing of metal particles in a controlled from its surface using heat from laser.Laser Beam machining is widely used in cutting sheet and drilling…
A clutch is a mechanical device which is used to transmit rotating motion or torque from one shaft to another shaft when required. Clutch provides a temporary connection between input and output shaft. Clutch is situated between the engine and the gearbox. Using the clutch, we can engage and disengage power transmission from one shaft…
Electrochemical Honing is a process in which material is removed with help of electrical energy, chemical energy and honing process. For those who don’t know, honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrubbing an abrasive stone against it along a controlled path.In honing a hone tool is used. A…
Fluid is a substance which can flow. Flow of any substance means a contnuous relative motion between different particles of the substance.Both liquids and gases are included in fluids.A gas differ from liquid as the volume of the liquid becomes definite but volume of gas does not remain definite. The main properties of fluids are…
Surface Texture is defined as a degree of finish conveyed to the machinist by a system of symbols devised by a Standards Association. e.g ASA – American Standard Association, BS – British Standards.Surface Texture is the nature of the surface defined by four main characteristics which are Surface roughness, waviness, lay and flaw.Surface Texture is also…
Indexing Mechanism is a mechanism that is used for dividing the periphery of a workpiece into any number of equal parts. The machine used for the indexing mechanism is called indexing head. Indexing head is also known as a dividing head or spiral head.It is a specialized tool that allows a workpiece to be circularly…
A comparator is an instrument that is used to measure the precision of a given component by comparing the dimensions of a given component with the actual working standard. Pneumatic means air, and in pneumatic comparators, the air is used for magnification of the measured reading. A pneumatic comparator works on the principle that if…
Comparator is a device that is used to measure the roughness of the surface. It is a precision measuring instrument in the metrological field.Sigma comparator was developed by a company named Sigma Instrument Company, USA. It is mechanical comparator in which magnification ranges from 300 to 5000.This comparator does not require any power supply. Parts…
