阐述数控机床回参考点原理,针对数控机床回参考点过程中出现的问题,建立机床回参考点故障树。应用故障树分析法进行定性、定量分析,为快速排除数控机床回参考点故障提供理论参考。
The principle of reference point of NC machine tool is expounded. Aiming at the problems that NC machine tool returns to reference point, the fault tree of reference point of machine tool is established. Application of fault tree analysis qualitative and quantitative analysis, to quickly rule out the reference point of CNC machine tools to provide a theoretical reference for failure.
