Machining is one type of subtractive manufacturing processes where excess material is removed from the workpiece to produce intended feature. Conventional machining processes (such as turning, threading, facing, milling, shaping, drilling, hobbing, etc.) employ a wedge-shaped cutting tool to shear off the workpiece material in the form of chips. Such processes always utilize mechanical energy in order to remove material by shearing. Several non-conventional machining processes have also emerged over

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

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

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

In abrasive jet machining (AJM), a high velocity jet of abrasive particles accelerated in pressurized air (carrier gas) is made to strike the work surface. A nozzle is used to direct this jet towards the work surface maintaining pre-defined stand-off distance (SOD) and inclination angle. When abrasive particles thwack the work surface at high velocity, they remove material by micro-cutting (impact erosion). AJM is commonly used surface cleaning, such as

Advanced Manufacturing Processes (AMP) are developed with an aim to satisfactorily cater the need to modern days’ industrial demands of improved quality and miniaturized products. Non-Traditional Machining (NTM) processes are a subgroup of AMP that follows subtractive approach to gradually remove materials from the workpiece in order to impart desired shape, size and finish. Such processes can utilize different types of energy in their direct form. On this basis, NTM
