摘　　要：文章采用基于软硬件协同设计的方法研制开放式数控系统。在建立系统三层结构数学模型基础上,通过分析系统约束条件和优化目标,划分了系统软硬件功能,并建立了硬件抽象层,最后对系统软硬件功能进行了详细设计。目前,该系统在广州机床厂数控铣床上进行加工实验,加工半球的圆度误差小于12μm,实验结果满足工厂对数控系统的精度要求。An open CNC system based on hardware/software codesign is discussed in this paper. The threelayer structure mathematical model is built as the foundation of the system. By analyzing the system constraint condition and optimizing target, the system hardware and software functions are divided. This paper also presents the method of creating hardware abstraction layer and detailed design of the software and hardware function. The machining experiments with this system in Guangzhou Machine Tool Factory shows the roundness error of machining semi-sphere is below 12μm, which satisfied the precision requirement of the factory.
