We are going to look at the process, machinery, etc. in later paragraphs. But let's first make clear what CNC milling means and bring clarity to some of the more confusing points about the term itself.
First, people often ask for CNC machining when looking for milling. Machining entails both milling and turning but these two have distinct differences. Machining refers to a mechanical cutting technology that uses physical contact to remove material, using a wide range of tools.
Secondly, all CNC machining uses CNC machines but not all CNC machines are for machining. Computer numerical control is what lies behind these three letters. Any machine using CNC utilises computerised systems for automating the cutting process.
Therefore, CNC machines also include laser cutters, plasma cutters, press brakes, etc.
So CNC machining is a mix of these two terms, bringing us the answer to the question posed in the heading. CNC milling is a substractive fabrication method that uses computer numerical controls systems for automating the process
