Design of CNC System Based on ARM

NC technology, which directly decides the function and performance of manufacturing equipments, is the key technique group that supports the modern equipment manufacturing industry. Open computer numerical control system based on PC and the Windows operating system has been a major development direction and s study focus of the current numerical control technology. This paper brings forward a hardware design method of open CNC system based on ARM embedded microprocessor. By test and research, it is proven that the designed open numerical control has complete functions and excellent performance, and could meet the request of modern numerical control machine tool for open numerical control system.
