【Abstract】 By analysing and researching the CNC system based on traditional industrial controller, aiming at the deficiencies, an Embedded CNC system based on CORTEXA8 microprocessor and embedded operating system( Win CE7) is proposed. The combination of embedded real- time operating system and high performance microprocessor makes real- time multi task processing ability of the CNC system greatly improved, which makes up for the real- time deficiency of the traditional NC system. According to the require-ment of CNC machine tool for the communication efficiency, networked manufacturing and the development of industrial wireless communication, completing communication of machine tool by using the Zig Bee wireless module. The debugging of the system shows that : the module of NC system is working properly, and can realize the wireless communication between the host computer and the controller.更多还原
