A high quality of the machined surface can be achieved which is comparable to that obtained by grinding. When machining hardened materials the specific cutting forces are substantially higher. This requires an adequate spindle power of the machine tool.

Conventional machining can be defined as a process using mechanical energy. The three main forms of energy used in non-conventional machining are thermal, chemical and electrical energy. Examples. Examples of conventional machining processes are turning, boring, milling, shaping, broaching, slotting, grinding etc.

There are three main kinds of machining: turning, milling, and drilling. There are other processes that also fall into the category of machining, but when it comes to modern machining processes, turning, milling, and drilling cover the majority.

A machining process is called non-traditional if its material removal mechanism is basically different than those in the traditional processes, i.e. a different form of energy (other than the excessive forces exercised by a tool, which is in physical contact with the work piece) is applied to remove the excess material …

Classification of Non-Traditional Machining These can be classified according to the source of energy used to generate such a machining action: mechanical, thermal, chemical and electrochemical.

The energy forms include mechanical, electrochemical, thermal, and chemical. The basics of nontraditional machining operations, such as jet machining, ultrasonic machining, electrochemical machining, electric discharge machining, laser beam machining, and so on, are considered.

Abstract:- Non-traditional machining (NTM) processes are now being widely used to generate intricate and accurate shapes in materials, like titanium, stainless steel, high strength temperature resistant (HSTR) alloys, fiber-reinforced composites, ceramics, refractories and other difficult-to- machine alloys having …

Non-traditional manufacturing processes is defined as a group of processes that remove excess material by various techniques involving mechanical, thermal, electrical or chemical energy or combinations of these energies but do not use a sharp cutting tools as it needs to be used for traditional manufacturing processes.

Traditional machining process is increases hardness of work pieces material results in a decrease of economical growth. Non Traditional manufacturing processes can be as a group of processes or activities that cut material by utilizing mechanical thermal and chemical energy or combination of this energies..

Hybrid machining processes are based on the simultaneous and controlled interaction of machining mechanisms and/or energy sources/tools having a significant effect on the process performance to get the benefits and also to overcome the limitation of constituent individual process.

Definition: Ultrasonic Machining is a non-traditional process, in which abrasives contained in a slurry are driven against the work by a tool oscillating at low amplitude (25-100 microns) and high frequency (15-30 kHz). Process: Ultrasonic machining is a mechanical type non-traditional machining process.
