What are the Advantages of Computer Numeric Control For CNC Milling?
All of the movements of CNC mills rely on Computer Numeric Control, which is a computer program derived from a 3D digital file of the desired finished part. Early automated machine tools relied on punch cards to control their basic movements in a systematic fashion. This technology worked but it was a slow and cumbersome system and punch cards could not be modified once made. These were later replaced by magnetic tapes, disk drives and now fully digital instructions.
