Numerical control is the abbreviation of numerical control, and numerical control technology is a method to control mechanical movement and machining process by using digital information.
In the early days, there were two versions:
NC(NumericalControl): stands for ancient and primitive numerical control technology.
CNC (Computerized Numerical Control): Computer numerical control technology-new edition, the preferred abbreviation form of numerical control.
NC may be CNC, but CNC is by no means an old CNC technology.
Extended data
The NC machine tool automatically processes the machined parts according to the pre-programmed processing program.
According to the instruction code and program format specified by the NC machine tool, we write the processing route, process parameters, tool path, displacement, cutting parameters and auxiliary functions of the parts into a processing program sheet, and then record the contents of this program sheet on the control medium, and then input it into the NC device of the NC machine tool, thus guiding the machine tool to process parts.
