摘要：In order to realize a high speed and high accuracy prosthesis shaping equipment (PSE) control system, this paper proposes a new software-hardware architecture of a five-axis high performance NC system. The software part of the proposed architecture follows the rules of the hierarchy and modularity. The inheritance, scalability, and stability are ensured on the whole system and local parts. According to the idea of modular design, the framework uses the client-server mode in the communication and scheduling level. With this way, the reliability of the module management is ensured. The hardware part of the proposed architecture consists of two main parts: the controller and I/O module. The controller is based on FPGA and uses PCI bus and IPC interface. The I/O module is based on ARM
