A CNC machine is a computer controlled carving machine.
CNC= Computer Numeric Control.
In most cases a CNC machine is programmed by a programmer using CAM software who uses the software to apply tool paths to a 3D or 2D model of the part they want to make.
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.
CNC machine works like the Robot, which has to be fed with the program and it follows all your instructions.
