摘　　要：以大口径光学元件精密与超精密磨削为监控对象,搭建磨削机床智能监测系统,探索智能磨削监控共性技术。监测系统以NI-PXI为主要运行硬件平台,建立与数控系统的通信,以机床内部、内置和外置传感器相结合的方式,自动获取机床运行过程和磨削加工过程的重要动态过程信号以及其他相关数据,通过对磨削机床全生命过程延伸数据体系的管理与分析,实现机床热平衡监测与热误差补偿、磨削液循环监控以及砂轮磨削性能退化在线评估等目标,以智能监控方式确保磨削机床长期平稳运行和加工质量稳定。Diamond wheel grinding machining is essential for the accuracy and efficiency of the large scale optical lens. Monitoring system is the indispensable part of the new generation grinding machine for the high demand of the reliability and stability. This paper is dedicated to the intelligent monitoring system of the precision grinding machine. PXI platform of National Instruments Corporation is used to acquire processing signals during machine operating and grinding. PXI controller is connected with the numerical control system of the machine, and the internal sensor signals and the processing parameters can also be output to the monitoring system. All the dynamic and static data related to the machine are stored and managed by the monitoring system database. Thermal error of the machine is acquired by the monitoring system and compensated for high machining precision. Grinding fluid circle system is also monitored and the numerical control system can give alarm for the emergency. Grinding wheel performance is real-time predicted which can give reliable guidance for wheel dressing.
