Abstract: According to certain serial NC turret locale test data and small sample Weibull distribution method based on Bayesian theory, for NC turret reliability model, is proposed. For the two parameters of the reliability model, swarm optimization algorithm is used to estimate parameters. More accurate results of the analysis can be got, using this modeling approach to establish the reliability model of NC turret.

Key words: machine tool, NC turret, reliability model, small sample, particle swarm optimization
