摘　　要：数控机床的参考点是作为机床确立坐标系的重要依据,一旦参考点的确立发生故障,就会使加工零件坐标系的建立出现故障,影响加工速度和机床运行效率。研究西门子840D SL数控系统回参考点的工作原理和工作方式,并根据现场故障现象实例分析和排除设备故障,从而提高排故的速度和机床运行效率。CNC machine tool reference point is important for the establishment of the machine coordinate system.Once the reference point establishment fails, it will make the machining coordinate system failure and affect the processing speed and effi-ciency of machine tool.This paper studies the working principle and working mode of the reference point of the SIEMENS 840D SL numerical control system,and analyzes and eliminates the equipment fault according to the fault phenomena in the field.
