摘　　要：分析了实时多任务操作系统RTLinux在数控系统螺纹加工设计中的应用。针对螺纹加工过程中常见的技术问题,提出了在RTLinux体系结构上,实现高精度螺纹插补的算法,给出了计数脉冲信号中断处理和柔性加减速控制的方法。实践证明,基于RTLinux的螺纹加工数控系统,既能够保证系统的实时性,同时能满足人机交互的要求。The application of real-time multi-task operating system, RTLinux, in the design of CNC lathes thread processing system is analyzed. Regarding common technical problems in the process of screw threading, based on the structure of RTLinux, an algorithm for high-precision screw thread interpolation is presented, and a method of the counting-signal interrupted processing and flexible acceleration-deceleration control is given. It has been proved that the new CNC system based on RTLinux can meets the real-time control requirements.
