【Abstract】 CAD/CAM is Based on the numerical control (NC) technology.With rapid development of NC technology,more and moee kinds of NC machine tools have been created.It is imperative to have a kind of economical NC machine tool that can display both figures and processing trace.This kind of NC machine tool can automacically program and process spares as long as inputting data.Therefore,this GNC numerical controlled communication system with figure-displaying that automatically programs with advanced computer longuage has been developed .更多还原
