An unconventional machining process (or non-traditional machining process) is a special type of machining process in which there is no direct contact between the tool and the workpiece. In unconventional machining, a form of energy is used to remove unwanted material from a given workpiece.

Non-conventional machines, on the other hand, are those machines that operate automatically with the help of computers and there is no need for human intervention or operator. These are usually controlled by an automatic robot or computers. Examples of operations that uses non-conventional machines are car painting in car manufacturing plants, welding car units and in manufacturing processes where in there is extreme high and low temperature involved that humans cannot withstand.

Non-traditional machining has the following characteristics: The hardness of tool materials can be significantly lower than that of workpiece materials; The material can be processed directly using energy such as electric energy, electrochemical energy, sound energy or light energy.

Non-traditional machining can be thought of as operations that do not use shear as their primary source of energy.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.Non-traditional machining processes can be classified according to the source of energy used to generate such a machining action: mechanical, thermal, chemical and electrochemical.Industrial requirements that lead to the development of non-traditional machining depends on hardness, strength,flexible or slender to support the cutting or grinding forces and complex shape of the part that needs to be machines.
