The Application of Performance Degradation Analysis in Machine Tool Spindle

Abstract:

As a key part feature of the machine, machine tool spindle has the characteristics of high reliability and high precision. The traditional test methods used to short the test cycle and analyze failure life of small sample data are inappropriate. Firstly, the reliability testing system of machine tool spindle was expounded; then, research status and the statistical analysis method of the performance degradation analysis used in the reliability test of machine tool spindle system were expounded. The influence to the credibility of the reliability test for machine tool spindle was put forward and analyzed: stress selection, feature selection, failure threshold selection and small sample analysis. Accelerated degradation test was given for further research in the reliability test for machine tool spindle.
