CNC machining (Computerized Numerical Control) is a technology for manufacturing precision parts, using a machine equipped with a microcomputer that is integrated into the control part of this machine. The production of parts is therefore carried out in an automated manner. Machining is called a type of defective machining, consisting in removing (cutting) small parts of the processed material. The removed layer of material is transformed into a chip. The scope of this machining includes services such as milling, turning or grinding.
