Study on Reliability Test Methods of Machining Center

As the main subject of the reliability research, the reliability test is an important technological way to improve the reliability of the machining center (MC). Based on the failure characteristics and reliability research status of machining center, some related issues to the MC’s reliability test were studied in this paper. Three reliability test methods of MC, field test, laboratory test and virtual test were introduced, and the advantages and disadvantages were analyzed. It has some engineering significance as it provided a guideline to select a correct and effective method to the reliability test of MC.
