A CNC controller controls each and every movement of the CNC machine by issuing commands through the CNC softwareIn essence, it is just like a human brain that controls each movement of the human bodyThe controller is made up of components such as a circuit board with various electronic components, and the software which is passed on to the controller from the computer that executes the command once it is deciphered and the appropriate motors are activated.

Job of this piece of Equipment

A CNC machine consists of one section that actually does the desired job-work, be it drilling, milling, cutting, etcHowever, it needs to get the commands and co-ordinates before it can start the jobA CNC controller is assigned the work of converting a computer program, which essentially is a set of commands that is fed into it by a programmer or controller into actual physical motionThe controller then deciphers these commands and proceeds to activate the related mechanical part of the CNC machine such as the driller, cutter, etc.
