Abstracts: Computerized Numerical Control(CNC) m/c is one in which the functions and motions of a machine tool, are controlled by means of prepared programmed containing coded alphanumeric data. CNC uses coded instruction the code used to program CNC units is generally called "Gcode" and "M-code". So, our project is the maintenance of CNC machine and programming. Many components are manufactured in CNC, it’s a vast field of manufacturing of products .So we have chosen this project because it is beneficial to our college faculty and we can expand our knowledge regarding CNC machine to students of college. And how maintenance and working of CNC is to be done. CNC turning center was available in our college but there was no one in our college to operate the machine so the machine is in unworking condition. There were many technical and non-technical problems associated with this machine. Problems are as follows: ? Unsuitable work place. ? Incorrect electric supply ? Low hydraulic pressure ? Foot pedal switch was not working due to problem in the limit switch. ? Jamming in the chip conveyor. ? Service require in chuck, turret, etc. ? Lubrications requirement.
