Subtractive manufacturing, such as CNC milling and turning, removes material from a block or stock until only the required shape remains.
Computer Numerical Controlled (CNC or just NC for short) machining describes end-to-end component manufacturing that is highly automated, thanks to computer-aided design and manufacturing programs. A part starts as a digital CAD file, which is converted into the commands and toolpaths needed to produce the part in a particular machining center. These commands dictate what tools to use and when to use them to cut the features of the required part.
