Different forms of energy (such as mechanical, thermal, electrical, chemical, electro-chemical, light, etc.) are directly utilized in advanced machining processes to realize material removal from the workpiece for fabricating intended 3-D feature following the subtractive manufacturing approach. Plasma Arc Machining (PAM) is one such advanced machining process where thermal energy (heat) is primarily used to melt down and vaporize material from the workpiece.

Thermal plasma is the ionic form of matter that is obtained by heating suitable gas to a very high temperature. Plasma consists of excited ions of gaseous atoms and free electrons (thus plasma can conduct electricity). Localized temperature of plasma can reach 30,000°C or even more. Such a high temperature can virtually melt and vaporize any material regardless of its physical state. An artificially created controllable jet of high temperature

Non-traditional machining (NTM) processes can directly employ various forms of energy for removing material from workpiece in order to fabricate the intended 3-D feature. EDM, LBM, EBM, and PAM are four common NTM processes that use thermal energy (heat) to selectively remove material. In these processes, material removal mostly takes place in vaporized and sometimes in molten state. The source of heat is, however, different for these four processes. Laser

Non-traditional machining (NTM) processes can directly utilize different forms of energy (like mechanical, thermal, chemical, electric, light, etc.) to selectively remove material from the workpiece in order to fabricate intended 3-D feature. These processes eliminate the barrier imposed by mechanical strength and hardness of the workpiece for processing by a conventional metal cutting process. Several NTM processes have emerged over the last few decades, which include AJM, USM, CHM, ECM,

Several advanced machining processes have been developed over the last few decades to cater the evergrowing demand of high quality small-scale products made of a wide variety materials with highly finished surfaces and close tolerance. Laser beam machining and ion beam machining are two such processes that follow subtractive manufacturing approach to fabricate intended features with improved accuracy and tight tolerance. However, their working principle and extent of capability are

Gear drive is one part and parcel of mechanical power transmission system that transmits power and motion by successive engagement and disengagement of teeth of driver and driven gears. There exist four basic types of gear, namely spur gear, helical gear, bevel gear and worm gear. The spur gear and helical gear are applicable for power transmission between two parallel shafts, whereas bevel gear is useful for two intersecting shafts

Double helical gear and herringbone gear

Solid

In helical gears, teeth are cut at an angle (called helix angle) with the gear axis in the form of helix on the cylindrical gear blank. It replaces sudden engagement and disengagement of teeth (as in spur gear) by gradual mating and thereby reduces wear, vibration and noise. However, a pair of mating helical gears induces axial thrust force that is ultimately transferred to the bearings, which necessitates bulky and

Gear drive is most widely used mechanical power transmission system in small to large scale machineries. It is one engagement type positive drive (no slip) suitable for transmitting motion, torque and power over comparatively small distances (usually below 1 m) and also modifying them as per requirement. Power is transferred from driving shaft to driven shaft by means of successive engagement and disengagement of teeth cut on the cylindrical gear

Gear drive is one important mechanical power transmission element that can transmit power and motion from one shaft to another by means of toothed wheel rigidly mounted on the shafts. It is one engagement drive that indicates power transmission occurs by means of successive engagement and disengagement of teeth of two gears.

Mechanical power transmission system takes help of several drives and elements in order to transmit power, torque and motion from one shaft to another shaft. Such drives can be either engagement type (gear drive and chain drive) or friction type (belt drive and rope drive). Belt drive is one reliable mechanical power transmission system that is commonly used to transmit power and motion over considerably larger distance (even up to

Majority of mechanical machine units are driven by a prime mover, which converts mainly electrical energy into mechanical energy (usually in the form of rotation of a shaft). Power generated by the prime mover is transferred to the intended location for driving various elements of the machinery. Several power transmitting elements are used for such transmission purposes; each of them has specific advantages and disadvantages. Gear drive, belt drive, chain

Basic purpose of mechanical drive is to transmit torque, motion and power from driving shaft (usually a prime mover like an electric motor) to driven shaft, and also to alter the intensity, direction and speed as per the requirement. There exist several mechanical drives to fulfill varying industrial and machinery requirements. Such drives can be classified into two major categories—positive drive and non-positive drive. A positive drive is free from

In many engineering applications, power is required to transmit from one point to another. Various power transmission systems such as electrical, mechanical, hydraulic, pneumatic, etc. can fulfill different requirements. Mechanical power transmission systems are used to transmit power, motion and torque from driver shaft (a prime mover such as electrical motor) to the driven shaft. Changing direction, speed and intensity are also important tasks for such transmission systems. There exist
