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

Machining

Cutting tool is a part and parcel in every conventional machining process. Tool material and geometry are two active parameters that influence process capability and machinability. For uninterrupted material removal, the tool material should be harder than the workpiece material. In addition to the hardness, tool material should ideally possess certain common properties, such as high strength, high toughness, high fatigue strength, shape retention capability at high temperature, high thermal

Non-traditional machining processes can directly utilize various forms of energy to remove material from in workpiece. For example, AJM, USM, WJM and AWJM processes are based on mechanical energy; CHM is based on chemical energy; ECM is based on electrochemical energy; and EDM, LBM, PAM and EBM are based on thermal energy. Since Electron Beam Machining (EBM) is one thermal energy based process, so here material is removed by melting

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

Macro-scale hole fabrication on a solid surface requires several different metal cutting operations based on the size and accuracy requirement. One typical series for hole making can be— (i) Centering, (ii) Drilling, (iii) Boring, (iv) Reaming and (v) Honing. Centering is carried out to locate the hole for easy and accurate alignment of a drill. Although it is optional, but centering can improve precision. Drilling is a process of originating

In order to make a macro-scale hole on a solid surface, a series of different machining processes are carried out depending on the finish and tolerance level requirement. One typical series of hole production can be— (i) Centering, (ii) Drilling, (iii) Boring, (iv) Reaming, and (v) Honing. Centering is performed to locate the hole center, drilling is carried out to originate a hole and boring is carried out to enlarge

Machining

In conventional machining operations, the cutting tool comes in physical contact with the workpiece to remove material in the form of chips. This chips flow over the rake surface of the tool before leaving the cutting zone. Presence of relative velocity under high contact pressure between the flowing chips and rake surface of the tool leads to excessive rubbing and heat generation. Excessive cutting heat or temperature has several detrimental

Cutting Tool or Cutter is a wedge shaped device that compresses the workpiece material during machining to gradually remove excess material by shearing in order to obtain desired shape, size and accuracy. Geometry, orientation and material are three important factors that influence performance of a cutting tool in accomplishing material removal. Every conventional machining operation employs a physical cutting tool. Although basic shape and feature of such cutting tool vary

Non-Traditional Machining (NTM) processes employ different forms of energy in their direct form to removal material from the workpiece. Such energy forms include mechanical energy (AJM, AWJM, USM), chemical energy (CHM), electro-chemical energy (ECM), thermal energy (EDM, LBM, EBM, PAM), etc. The mechanism of material removal also varies accordingly. As the name suggests, chemical machining employs an appropriate chemical solution to etch away material from work surface. Such chemical solution

By definition, machining is one of the secondary manufacturing processes by which excess material is gradually removed by shearing from a pre-formed blank in the form of solid chips using a wedge shaped cutting tool in order to get desired shape, finish and tolerance. It follows subtractive manufacturing approach to fabricate desired object. Examples include turning, threading, facing, drilling, boring, milling, shaping, etc. Such conventional machining processes are unable 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
