We could say that CNC is an electronic driver of the Cutting System dependent on the designs by the client and the profiles of the parts to be taken a shot at nourished into the framework before the start of the activity. Making use of built-in electronic and software automation, CNC can control the cutting process calculating all available parameters, both the ones determined by the Cutting code (G-Code) fed into it beforehand and the real-time cutting data provided by the relevant sensors. It adjusts the proper gas mixture and velocity, the feed rate and the torch movement along the three axes, and the power of the Source. The cutting process is automatically continuously adjusted in the best way, much better than by the most experienced operator.
