In general, the difference is that an NC machine requires the user to program in coordinates (x,y,z), while a CNC machine allows the used to import a CAD/CAM file or program a visual curve b) Why was the noise increasing with the decrease of diameter as the machining progressed? Whenever the noise increased the machine was working harder....
