Abstract

CNC machining centers were analyzed by the failure mode, effect and criticality analysis (FMECA) method for identifying the weakest links of a CNC machining center and obtaining that the spindle system is the primary factor that affects the reliability of CNC machining centers. The spindle system was analyzed at different feed speed by the finite element method. The results have important guiding significance for the reliability research of CNC machine tools.
