What does NC machining mean?

I have been engaged in mold and NC programming 10 years. CNC generally refers to digital control. There are many such machine tools. It can be said that almost all machine tools now have CNC numerical control. More detailed information is available online. You can have a look. Here I will give you a brief explanation:

NC machining refers to machining with NC machining tools. CNC refers to programming and controlling CNC machine tools with CNC machining language, usually G code. The G-code language of NC machining tells the NC machine tool which Cartesian position coordinate to use, controls the feed speed and spindle speed of the cutter, and the functions of the cutter converter and coolant. Numerical control machining has great advantages over manual machining. For example, the parts machined by numerical control have very high precision and good repeatability. Numerical control machining can produce parts with complex shapes that cannot be completed by manual machining. Numerical control machining technology has been widely popularized, and most processing workshops have numerical control machining capabilities. The most common CNC machining methods in typical workshops are CNC milling, CNC turning and CNC wire cutting (WEDM). CNC milling tools are called CNC milling machines or CNC machining centers. Lathe used for NC turning is called NC turning center. The G-code of NC machining can be programmed manually, but it is usually that the workshop automatically reads CAD files with CAM software to generate G-code programs to control NC machine tools.
