Human being is a characteristics species among all living species that distinguish itself from all other living species by its ability to magnify and extend its own capabilities. Earlier, the human being has been described as a tool utilizing other animals for carrying out the work generally ascribed by him for himself. The capabilities of man along with his desire for knowledge and improvement leads to the development of a device called “A machine”. A machine, as per one of the definitions given in ‘Oxford English Dictionary’ is “An apparatus for applying mechanical power consisting of a number of interrelated parts, each having a definite function.” The evolution of machine is attributed to the propagating power of machine which is inherited from its ancestor machines. Existing machine tool makes the pathway for the manufacturing of more advanced machine tools which successively serves to accelerate the evolution of new machine tools.
