Let me first introduce you about what is CNC machine, so CNC stands for Computer Numerical Control. When computers are used to control a Numerical Control (NC) machine tool than the machine is called CNC machine. In other words the use of computers to control machine tools like lathe, mills, shaper etc is called CNC machine.
The cutting operations performed by the CNC is called CNC machining, in CNC machining, programs are designed or prepared first and then it is fed to the CNC machine. According to the program, the CNC controls the motion and speed of the machine tools.
How CNC Machine Works
•First the part program is inserted into the MCU of the CNC.
•In MCU all the data process takes place and according to the program prepared, it prepares all the motion commands and sends it to the driving system.
•The drive system works as the motion commands are send by MCU. Drive system controls the motion and velocity of the machine tool.
•Feedback system, records the position and velocity measurement of the machine tool and sends a feedback signal to the MCU.
•In MCU, the feedback signals are compared with the reference signals and if there are errors, it corrects it and sends new signals to the machine tool for the right operation to happen.
•A display unit is used to see all the commands,
programs and other important data. It acts as the eye of the machine.
