cnc is abbreviation of Computer number control. Is a computer numerical control, refers to the computer as a general numerical control system in the control device, used for processing machinery parts.

Is currently widely used in manufacturing as a processing technology, it can be said that now the symbol of manufacturing. cnc machining center give full play to the computer fast computing and storage capabilities. It is characterized by the simple and customary language to describe the geometric shape, processing technology, cutting parameters and auxiliary information of the processing object according to the rules, and then the numerical calculation by the computer, calculation of the movement trajectory of the tool center, post-processing, Generate parts processing program, and process simulation. For the complex shape, with non-circular curve contour, three-dimensional surface and other parts of the preparation of processing procedures, automatic programming method with high efficiency and good reliability.
