Accelerated life testing method of machine tool numerical control system

The invention discloses an accelerated life testing method of a machine tool numerical control system, comprising the following steps: carrying out the accelerated life test on the machine tool numerical control system; analyzing and processing testing data; and evaluating the mean free error time of the machine tool numerical control system. The consistency of the testing data by the accelerated life testing method is better than the consistency of the on-site collected data, and the service life distribution condition and the failure occurrence condition of the machine tool numerical control system can be rapidly evaluated.
