Abstract： FMECA played an important role in reliability maintenance of CNC machine tools. Current researches focused on 4 aspects：comprehensive evaluation of multiple factors， integration of multi-source hierarchical information，integration of multiple analysis methods，and dynamic characteristic modeling. By systematically combination of existing research results，the advantages and existing problems of the 4 aspects were analyzed.Evolution path of machine tool failure modes，effects and criticality analysis were explained by the integration of the characteristics of industrial needs， which provides a theoretical basis for building a high-precision machine tool reliability evaluation system.

Key words： CNC machine tool；reliability analysis； failure mode，effect，and criticality analysis （FMECA）；research status
