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. A high temperature jet of thermal plasma

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

Physics, Thermodynamics

Energy may exist in different forms. It can be light energy, thermal energy, potential energy, kinetic energy, chemical energy, nuclear energy, etc. Every physical matter (or body or thermodynamic system) intrinsically possesses certain amount of energy in one form or another. Such energy can be converted from one form to another for storing it within the same body. It can also be transferred from one body to another with or

Thermodynamics

Thermodynamics

Thermodynamic system is defined as a definite quantity of matter or a region in space upon which attention is concentrated for the analysis of a problem. Everything in this universe external to the system is called surroundings. The system is separated from the surroundings by the system boundary. Every interaction between the system and surroundings occurs across the boundary. There are two distinct ways of interaction between system and surroundings,

Thermodynamics

Thermodynamic system refers to a definite quantity of matter or a specific region in space upon which attention is concentrated for the analysis of a problem. Each thermodynamic system has certain characteristics by which its conditions can be described. Such characteristics are known as thermodynamic properties. Properties are always macroscopic in nature (i.e. observable or sensible with simple instruments). Properties are also point functions (i.e. property has a definite value

Thermodynamics

Thermodynamics

For the analysis of any thermodynamic problem, the concerned matter or a region is considered as the system. By definition, thermodynamic system is defined as a definite quantity of matter or a region in space upon which the attention is focused for the analysis of a problem. Everything in the entire universe external to this system is called the surroundings. The system is separated from the surroundings by a boundary.
