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,

Among the mechanical energy based non-traditional machining processes, water jet machining (WJM) and abrasive water jet machining (AWJM) are two common processes that have wide variety of applications, starting from metallic industry to textile and lather industries. In water jet machining, clean water is pumped to a high pressure (2500 – 4000 bar) with the help of intensifier and the pressurized water is delivered to the work surface in the

Machining

Machining

Fabrication indicates building the desired component using one or more manufacturing processes. Manufacturing is one technical term that is defined as a step by which raw material or scrap is converted to the useful product by adding substantial values. The manufacturing step consists of seven basic processes – each of these processes once again consists of many operations. Machining is just one manufacturing process; there are many others as discussed

Machining

In the field of mechanical engineering, “Machine” is defined as an assembly of mechanisms that are clustered together in such a way that it can perform certain operations by utilizing electrical, mechanical, hydraulic and/or pneumatic power, and thereby reduces the requirement of human effort and intervention in doing the task. However, “Machine Tool” is not exactly same with the machine. The term Machine includes wide variety of machinery, whereas Machine

Machining

In the field of mechanical engineering, Machine is defined as an assembly of mechanisms that are clustered together to perform certain operations by utilizing electrical, mechanical, hydraulic and/or pneumatic power. Total number of mechanisms exist within a machine may vary from just few to few hundreds! Accordingly size of a machine also varies. Some machines, irrespective of their size, are portable. For example, a hand drill (small machine) and a

Mechanical energy based non-traditional machining (NTM) processes directly utilize mechanical energy to gradually remove material from the workpiece primarily by erosion. Examples of such processes include abrasive jet machining (AJM), water jet machining (WJM), abrasive water jet machining (AWJM) and ultrasonic machining (USM). In abrasive jet machining, abrasive particles are first mixed with the compressed gas at a pre-defined mixing ratio. This mixture is then directed towards the workpiece in

Machining

Machining

Machining is basically one material removal process where excess material is sheared off by the mutual interaction between workpiece and cutting tool. There exist several machining processes to cater the need of processing a wide variety of workpiece materials in innumerable ways. For examples, lathe operations (such as straight turning, taper turning, internal turning, threading, grooving, etc.) are primarily carried out to generate cylindrical or conical surfaces. Milling operations are

Machining

Conventional machining operation utilizes a wedge shaped cutting tool having one or more sharp cutting edges to facilitate shearing. To achieve material removal, three relative motions between workpiece and cutting tool are indispensably necessary. These are also called process parameters. One of such three relative motions is cutting velocity, other two being feed motion and depth of cut. In few machining processes, the cutting velocity is imparted either by rotating

Primary objective of any subtractive manufacturing process is to remove layer by layer material from a solid 3-D blank to achieve desired shape, size and finish. Achieving high dimensional accuracy, close tolerance and surface finish are usually not possible by conventional machining processes like turning, milling, shaping, planing, drilling, etc. Such processes are mainly applied for bulk removal (stock removal) of material with high material removal rate. In order to

Machining

In conventional machining, the cutting tool compresses a layer of work material to shear it off in the form of chips. Both the cutting tool and the workpiece is rigidly mounted on the machine tool maintaining appropriate orientation. All relative motions are also offered by the machine tool to smoothly accomplish material removal. In mass production of a product in conventional machine tool, same work is required to perform repeatedly

Economic production of near-neat shape products with close tolerance and high accuracy is a challenging task for manufacturing industries. Two different approaches have evolved over the years for efficiently and economically fabricate such products. In one approach material is added layer by layer to build a 3-D component, while in other approach material is removed layer by layer to obtain desired 3-D product. As the name suggests, in additive manufacturing
