Retrofitting a conventional milling machine to a computer numerical control (CNC) milling machine using DC servomotor / Joupin Sabin

CNC milling machine is one of the machine that ever manufactured which evolved from the so-called computer numerical control (CNC) technology. As far as CNC is concerned, the subject on CNC milling machine system is very wide. This thesis only provides some fundamental idea about the milling machine and CNC system. The knowledge of conventional milling machine as well as he CNC systems theoretically and practically is very essential in the retrofitting of the conventional milling machine to a CNC milling machine. The idea presented would enable someone to at least control an operation of basic CNC milling machine that is its XY table movement. Generally and theoretically, a conventional milling machine is retrofitted to a CNC milling machine by replacing the manually operated handwheels with electrical or hydraulic motors that can be controlled from digital computer. Also, In this thesis, an example of DC servomotors control system is provided and explained in certain extent which is needed in the project assigned.
